No Service on Vibrant - Vibrant Q&A, Help & Troubleshooting

I was previously on CM7 Nightly Build 8 when out of no where I experienced a drop in service. Figuring it was just a bug with CM7, I used Odin to get back to stock and then proceeded to flash Bi-Winning. My IMEI and Baseband is still listed but my phone will always say "No Service." Does anyone know what could be wrong?

This happened to me and it was because I needed a replacement SIM card. The TMob rep said I had been using a 2G sim for the last year and that it needed the 3G version. As to why it worked for a year he said that it just does work for a limited time and that time had obviously run out.
Worth a shot ...

What area are you from? I'm just south of Chicago. The last 2 days I have had large chunks of time where data has been unavailable. This is at my house where I have consistent 3g. I think they are up to something....

Thanks for the responses guys, I guess maybe I'll have to go to the Tmobile store and I'm on Long Island.
I just actually Odin'ed back to stock and while my phone still does not pick up any service at my house (which it usually had good service here) I went out and my phone did get some service near the mall in my area. It was only 1 bar though and it only picked up the edge network where usually in that area it would be full strength 3G service. So its not completely broken just extremely weaker than usual. Any suggestions?

the 2g sim card problem happened to me too, so that could be the problem!

No longer getting HSPA+

Just curious if it is my area I live in or me screwing around with my phone. I live in Fresno, CA and we've had HSPA+ here for a couple of months. I was averaging around 3mbps down and 1.5 up from my house and 4-5k at my office. All of the sudden I am getting extremely poor 3g speeds. 200-300k at my house and 600-700k at my office. Just wondering if anyone is from the area here and if they are experiencing the same issues.
The only thing I did was flash the JPM froyo to mess around. I am now back running Bionix fusion 1.1 with stock kernel and ji6 modem.
Edit: Going to Odin back to official JI6, I'll post results in case anyone is curious.
Edit 2: Didnt work, still getting the same speeds. Just talked to a friend of mine down in southern CA and he is no longer getting HSPA+ speeds on his vibrant. Anyone else having an issues like this?
Anyone else in HSPA+ areas having this happen?
yes. very strange. and its ****ing pissing me off too.
i work in addison, tx (dallas suburb basically) and i used to get 4 to alllmost 6mbps down at work. up speeds have always sucked a nut but that's fine with me because you're only sending http requests most of the time so 300kbps is fine.
past few months it has become VERY spotty. some days my down speeds are under 200, the ping times out, and my up speeds are 1.2-2mpbs (WTF!?) this is with four full bars most of the time. its so bad that with the awesome ups, pages IMMEDIATELY time out, i cant even browse little mobile sites like m.facebook.com a lot of the time.
outside of this area, everything seems to go back to almost normal again. i no longer get 4+ down speeds anymore, but they're better, 1.5-2 i can live with.
it started happening before i rooted the phone and flashed any roms. and has never gone back to normal with the other roms i've tried, so im pretty sure it is a network issue.
the only other thing i could think of is maybe my sim card is crapping out, but i dont have another sim to test, as all of my friends dont have tmobile smartphones with a data plan and i'm way too lazy to go back to stock and go argue with a tmobile store rep to get a new sim card for free. mine is probably at least 6 years old at this point.
see what i mean? this could be better i guess since it wont let me select a server near me (this is renton, wa)
pings, in order as those are shown in the screencap are:
92ms
160ms
111ms
93ms
also, instead of UMTS like it used to say, now it just says "Network: Cell"
this makes no sense.
I'm running stock jfd firmware still and my 3g has been sucking ass as of late as well and I'm near Dallas. I was in Addison Saturday night with full bars and good signal and couldn't do anything. Tried espn mobile and it was so slow. Forced it back to edge and it was a lot better. Tmo 3g here in dfw is hit or miss.....mostly miss. I was in Grapevine a cpl wks ago and was getting 5mbps down...never seen that before around here. But I still say its hit or miss mostly.
I have noticed that the 3g speeds I've been getting here in beaumont, tx are way below what I used to get as well. Sometimes 3g is even slower than edge!
I wonder if maybe the T-Mobile network is simply getting overloaded?
Sent from my SGH-T959 using XDA App
im in san antonio and im getting the same average of about 4.5/1.5 like i have since the network upgrade. no problems here so far...i did notice my friends G2 has the H instead of the 3G but isnt any faster than my Nexus or my Vibrant, i figured the g2 would blow away my phones but his g2 averages about 4.5/1....
ive asked this in several different threads and cant seem to get a straight answer. maybe im asking wrong, so I am trying to make my question as clear as possible:
I am trying to figure out if im getting tmobiles new network in my area; (4g/hspa+). before I get flammed, yes, i do realize that our phones wont get 21mps download speed on the new network and the best we should see is 7.2mps, but probably wont get that in real world experience.
So i have been getting better speeds in the past few weeks in my area (between 1.5 and 3mps download) but that alone does not tell me if i am getting a good 3g signal or poor 4g/what ever its called signal.
When you go into settings> about phone> status, it says mobile network type. I am assuming that the Mobile network type will change depending if on new network, 3g, or edge....? (hspa, hspa+, hsdpa) Can anyone confirm or deny that this should or will change depending on what area we are in and what type of data connection we are connected to?
The other way someone told me to check is by downloading mobile signal widget and it will display 3g or H. For me this does not seem very accurate but it does display 3g or H...
The reason I dont know if Im on their newest/fastest network is because they have a coverage map on their website for HSPA+. my city is not on it, but a city about 15-20 miles away is on it. I did not really think i would be getting it since its not my city, but like i said ive noticed somewhat faster speeds, nothing like 4-6 mbs download that would confirm it for me, but enough to make me unsure and question.
so sorry for the long post. basically just wondering if network type under about phone will change depending on if im getting normal 3g or their newer/faster network and if that mobile signal widget is an accurate way to tell
thanks

If you have a vibrant you never got HSPA+, you just benefitted from its speed, the phone isn't capable of the +

every single time ive bought a new phone from tmobile, the rep always takes the sim cards out of the box and uses my existing one.
a buddy of mine left tmobile because they wanted to charge him $20 for a sim card.
i actually brought that up with the tmobile twitter account and they just said "sim cards are usually not free"

That's strange. I've always gotten my sim cards free from t-mobile. Just tell them the existing one keeps giving you a sim card error and that when you purchased your vibrant they took the sim card that came with it (because they typically do). They will take your old one and replace it with a newer one.
I told the rep I would not buy the phone without a new sim. He immediately swapped it from my g1 to a new one.
doubt it will help, but have you switched to airplane mode, reboot and then turn airplane mode so it finds your network again? I didn't even have data this morning and that fixed it.
Remember t mo is in the process of a major upgrade to their network too...
Every time I buy a phone from a TMO retail store and they go to take the sim I tell them to keep their fingers off and leave it in the box because I paid for it already. What they will do is put it in their binder for when the next poor schmuck walks in having lost their sim so they can get charged for it.
They try to give you the same BS about it costing money and maybe that's true if you lose it, but not with a brand new phone purchase. Even my new Vibrant I ordered from loyalty came with a new SIM in the box. I just kept it as a spare. The things these stores do to double-dip a measily $20.
honestly i probably should have but i assumed it was normal since i have never had network connection issues when going to buy a new phone. i've never even batted an eyelash when they did this.
if i odin my phone back to stock and take it up to them i'll definitely bring it up if they try to charge me.

Service Problems?

So maybe once a week or once every other week at night, my phone does not want to get a signal. I usually have pretty a good signal, although I am in Iowa. I have done battery pulls and taken out the sim card for about an hour but whenever the phone boots up It has service for about 5 seconds, and then it just looses it. I tried taking it back to Best Buy and they called AT&T for me. AT&T said I just wasn't getting service. Anybody else have any problems like this?
I've always had spotty coverage, but it's due to my area. I live in an area with spotty LTE coverage, and when connected to LTE my phone cannot send or receive data. It pings back and forth between LTE and HSPA+ which is pretty annoying.
I only have HSPA+ in my area. I usually do well with that. I just dont understand why this only happens on select nights. I wont get service until tomorrow morning now.

(Telus S3) Shoddy service after root?

So I receive my Telus S3 on release day, activated it, and had no problems (that I noticed, but I was connected to WiFi most of the time.)
Rooted it about a week later, and I can barely get service. Rather, I'll get a couple minutes of connectivity, then it'll disappear for 5-10 minutes. It's not a corrupted IMEI, like this thread is discussing. I've since flashed a stock Telus rom on the phone, and I still have the same problems.
We have low LTE availability in the area, so I thought that may be the problem, but the same thing happens with setting GSM or HSPA in the network settings.

Sounds like a pretty curious case... have you uncovered any causes / solutions yet? Also, before you flashed back to the stock Telus rom, what were you using?
I have a similar issue happening also on my rooted telus phone. I rooted it the day I got it so I cant confirm on how it was before. It is running a stock ROM/kernel. What happens to me is my service will drop from 3 or 4 bars to no service or will show 1 bar but be unable to get any service anyways. Im not in an LTE area but I am in a dc-hspa+ area. Is this what happens to you as well?
The only fix I've found is wait 5-10 min for it to come back.

HTC Titan II drops cellular data connection randomly

Curious issue with my Titan II. Cellular data connection just fails at random intervals. Cycling airplane mode or rebooting the phone is the only way to get it back. HTC blames it on AT&T and AT&T blames it on HTC. I've spent hours on the phone with each. Even got a new Titan II from AT&T, but it went into this constant reboot loop, so I went back to the first unit.
Now comes the interesting part: I live in Detroit and have been traveling to FL quite a bit, this year.. and the issue DOES NOT HAPPEN IN TAMPA. Phone runs perfectly well, there. Here in Detroit, cellular data "up" time ranges from 5 minutes to 14 hours when static. 2 minutes to 20 minutes when driving around town. Drops are less frequent when streaming something.
HTC Titan II stock (FW: 2180.0400.118011.502)
Windows Phone 7.5 (7.10.8112.7)
4G SIM card (3rd one)
Appropriate data plan
Serious thanks for any ideas anyone has. Do I add an APN, throw the phone against the wall, or what? Please do not suggest I change to a different phone as that is not an option.

Yes, I'm facing the same issue.
It seems something related to wifi sleeping when the phone goes stand by and the solution could be keeping it alive in some way....like streaming..
I hope this will be fixed with AT&T Tango 8773 Update (Once it finally come....)

Are you sure you aren't hitting "black spots" on your network? If you have random connection drops in only particular area it is likely the masts and AT&T issue. I've swapped my provider from the one which did 2G/3G signals to 3G only provider. 3G only has better coverage and lesser black spots on the network and hence I hardly see any drops in connectivity. Don't hard reset or anything, it will only make you re-do the whole phone, won't help the cause.
Have you checked if two golden pins on the back cover are making good contact with phone?

Have to rule all of that out as it doesn't happen at all in Tampa. I can drive from Ybor City to Clearwater and back and never need to reset the phone. Here at home, I have four bars and will lose cellular data with the phone in a static location. Driving around in Detroit is guaranteed to make it drop cellular data even with the phone lit up and active. I can have Navigator running and it'll just quit loading maps and giving directions until I cycle Airplane Mode. In Tampa, this doesn't happen.
In Tampa, I've gone the whole week without any need to reset the phone. I can't walk from the gate to baggage claim in Detroit before it loses its data connection.

UPDATE: Cellular data connection is a little better with WiFi turned off. It won't lose it as quickly in a static location, but still loses it as I move between towers. Also had to reinstall a couple of apps that had stopped launching.
Is forcing Tango an option?
I have the same problem,
I live north of detroit.
my phone has been in to htc repair 3 times, i think they have replaced every part in it, the last time i got it back it held connectivity for 11 minutes.
this is on my home tower as well as several towers around me.
Normally all testing was done with wifi off, on towers where the lumia 900 and my wifes iphone have never lost data.
i have been waiting a week for a htc level 2 rep to call me.
we shall see
Keep me posted. Last time I spent time with HTC, they decided that - since the issue only happens in Detroit - that it was AT&T's problem. AT&T, naturally, claims that the problem doesn't appear on any other device, so it must be the device.
Can't wait for Windows 8 phones. I'm getting one.. ANY one.. the first day they go on sale.
Well I just got off of the phone with a level 2 rep from HTC, who seemed pretty confident that the problem is the rear cover. He is sending one out, and says if that doesn't fix it then it will be a phone replacement.

So, I'm in Florida for the week and noticed something.
In Detroit, the status bar says "4G"
In Tampa, the status bar says "LTE"
As before, I have not lost cellular data connection since I landed in FL. Kind of rules out the battery cover as the issue is gone, here. It appears the issue goes away in LTE areas while it's present in areas yet to get LTE. Detroit's LTE rollout hasn't happened, yet. So, it appears I've got another month of suffering before the problem is rectified.
One other note. With Internet Sharing set to ON...
In Detroit, my wife's laptop connects to the phone and can get internet.
In Tampa, my wife's laptop connects to the phone, but cannot get internet. It gets the error msg: "your computer is trying to use a dns server that is incorrect or doesn't exist"
My laptop works flawlessly connecting to the phone's Internet Sharing both in Detroit and Tampa. For the life of me, I can't find anything different in her settings over mine. Both are Win7. Hers upgraded from Vista, mine x64 and new this fall. Also, two internet-capable televisions connect to the phone and get to the internet flawlessly. But something with LTE doesn't like my wife's computer. Odd.
Honestly, I adore everything about this phone except for the data connection issue in Detroit (and a few other areas, it seems).
There HAS to be a setting or SOMEthing I can tweak to get this thing to work in Detroit.
Check battery cover, radio negotiation, firmware of radio

Hum.. that's curious. I had the original titan with similar issues.
I disabled wifi when not connected. I replaced battery cover also. The titan2 supposedly fixed that issue with the battery cover because it was a design flaw.
The radio supports 2G, 3G/4G/H and LTE. You may want to check it. You can set the radio it uses and not let the firmware decide which radio to use. You can check the service menu, I forgot the code. Just search for it.
If you use 2G, data and voice are not supported simultaneously. Check and make sure the contacts on the battery cover and on the phone are clear of debris. Use a solution to clean the contacts on the phone.
In the past I manually set the radio to 3G (HSPA and HSPA+) [HTC Pure, HTC HD2 on at&t]. The 3G radio is mature and should have less issues with the radio negotiation.
BTW, there is a keep alive wifi app also.
Thanks. I'll have to look for the codes. It's pretty obvious after going back and forth so much that the Titan II has a flaw with the way it handles AT&T's 4G. Scanning the maps from others who have had problems all show that they're in areas with 4G but without LTE.
Yeah, if I could force this thing to do LTE or 3G I think we'd be fine. It's the Best Phone Ever so long as it gets LTE, 3G or Edge. Anything else and it's crap.
Yes, back connector is okay and I've done this every way one can think of and kept notes. WiFi doesn't matter. On or off, the T2 will lose cellular data connection randomly in 4G areas. NOT in LTE areas. I'm only unable to test it on other carriers.
Similar problem with data
So I have had a similar problem -
I had a Samsung Focus, great phone, but I wore out the USB port - wouldn't charge consistently or sync. I figured I might as well use the insurance I had been paying. They sent me a Titan I - it had the bad microphone issue. So after some messing around they sent me a Titan II.
It has never had consistent data connection. I am in an area where I get the 4G icon (not LTE).
My experience tells me that if I move around and change cell, or lose signal in the cell I am in for any reason, then the phone will NOT connect back to data. It can (almost always) still get phone calls and send/receive texts and so on, but no data. Toggle airplane mode always fixes the problem, until the next time.
Originally HTC wanted to send me a new back cover - AT&T have been completely useless, they have no idea. Eventually after messing around with factory resets, powering on and off continuously, another new SIM card, HTC decided they want the phone repaired or replaced (level 2).
It is still inside the 30 day limit for exchanges from Assurion (AT&Ts insurance carrier) so it's getting replaced. I'll let you know if it fixes the issue, but I haven't been in an LTE area so I can't check that.
Personally I think it is a problem with handing off/reconnecting to 4G tower service - we'll see......
Anyone have the radio codes?
I've had the same problem since I got the device as well; but have noticed that it doesn't happen in all areas around me. My house is one of those areas though that I always lose connections. I've tried every APN / idea I've found on the internet with no luck. It's clearly something to do with AT&T towers. The only think I've not been able to try is a different SIM card in the same phone since it requires a '4G' sim card to even work at all. However the same SIM does work fine in '3G' only phones.
Going with the radio idea, does anyone have the codes to turn off the LTE radio? I just saw the list saying this phone will be long gone before AT&T ever gets LTE in Colorado so maybe just turning it off would help. Every code i found was for the T1 though and it didn't work on my phone.

UPDATE: HTC insisted on sending me a new SIM card cover (since it contains the radio's antenna). Despite my argument that the fact it works in Florida negates antenna as a suspect, they sent it along, anyhow. Naturally, there is no change. It still randomly drops cellular data. And now, I've picked up another spot on the freeway where my calls get dropped. Granted, it happened ONCE, so that could be any number of things. Long story short, it's not the antenna.
Next idea?
Well, I'm in Florida and found a spot where the phone fell back to 4G from LTE. Data issue returned. So, that takes geography out of the equation. The phone can't hold a data connection when using 4G. So, should I go for a fourth unit?
My addition:
AT&T recently rolled out LTE to my area in CT. I never had the problem before on straight 4G. Now, when I go from LTE to 4G (my drive every morning) data just stops working. I push it in to airplane mode and back out again and it works.
BTW - I am running Tango, so that is not likely to be a fix unless a radio update is released with it.

AT&T just switched on LTE metro-wide, last night. Now, the Titan 2 performs just as it does when I'm in Florida. It's nice having a data connection that'll stay good all over town, again.
I have spent some time discussing this with HTC and AT&T. Actually just got off the phone with HTC level 2.
I too have gone through all the options - new phone, new cover, new SIM card (you can just go into AT&T and ask for one, no charge), hard reset, everything.
From the information in this thread, and elsewhere I can say that the phone drops data on one of two things happening:-
- connection to tower is interrupted in current cell, but is re-acquired
- connection is handed off to adjacent tower as you travel to a new cell
Both these things will drop data IN 4G AREAS ONLY. If you are lucky enough to have consistent LTE in your area, you shouldn't have any problems.
Right now I'm working on getting the service menu codes so we can play with the radio settings. It sounds like HTC support reps have been forbidden to give these to end users on windows phone devices (I wonder why??!!).
If I get this information and it provides a fix for this issue, I will (obviously) post it, and I imagine HTC will as well. Here's hoping.....

Cell connectivity completely drops, then comes back, rinse and repeat

I received my new XA Ultra from Amazon yesterday. Popped in my SIM and started setting it up. It had two software updates out of the box, so I applied them, then started installing apps. I noticed that my cell connectivity would completely drop (no bars), then come back. When I checked in the Access Point settings, the option to discover carriers would appear, then disappear.
I assumed it was some kind of software corruption, so I factory reset, but it continued doing it. I also tried pulling the sim out and putting it back in several times. I can only assume that I somehow got a defective unit or that one of the software updates applied the radio incorrectly. I processed a return with Amazon and have a replacement coming later this week.
I hope Amazon doesn't turn around and resell it through warehouse deals. I have received a few devices from them that they clearly didn't test and I was very explicit in my comments for the return. I'm just hoping that my replacement doesn't exhibit the same issues because I'm not sure what else it could be. It's not my SIM. All of my other phones stay connected to AT&T just fine in the same spot.

Did you check before purchasing that it would connect to I'm guessing by AT&T US network's I know yours are different to ours in the UK. I've not had any problems with my normal xa but I'm in the UK

It's definitely fully compatible. It even downloads the correct APNs, but then they just disappear and the signal drops completely. I get full LTE speeds when it's working and nothing when it's not. I also tested a T-Mobile SIM and, while it holds onto the signal longer, it does the same thing (drops completely).
I plugged the phone into a computer and did a complete software restore, which didn't fix the issue. At this point, I'm sure it's either hardware or a really bad ROM update. I'm hoping it's hardware, because if not, that means that the replacement will have the same issue after applying the software updates to it.
This is my second Sony xa ultra with the same issue here's what happened
Purchases from best buy didn't setup until I got home had 2 update applied them signal drop and reset constantly I figured it was because I have bad reception in my area but the more I looked at the phone I noticed the build quality on the metal bumper wasn't sealed in some areas so I grabbed the packaging and headed back to Best Buy keeping note of the signal issues as I drove there (disconnected from WiFi of course) I noticed the signal did not drop connection at all on the way to Best Buy return the phone and explain to him the issues that I had at home with the signal and also wasn't happy with the build quality defect so I returned it and exchange for another one immediately popped the Sim in it downloaded my APN and I had LTE drove home no drop issues connected to wifi installed the two updates then I drop issue return

The replacement model I received from Amazon did it as well. Right out of the box, before updates, it was dropping the signal. Are you on AT&T?
I watched it really closely. I think I know what's happening. It's not falling back to HSPA. When the LTE is too weak, it simply drops completely until it can reconnect to LTE. If you set it to HSPA only in the mobile networks menu, you will never lose your signal. I tested it with both T-Mobile and AT&T with the same results.
This is a pretty major defect.
You might be on to something, yes I'm also on AT&T.. but I can't find HSPA in mobile network should it be GSM only or LTE (preferred)

It should be something like "GSM/WCDMA Auto" or "WCDMA only". Basically anything without LTE (except CDMA).
I'm honestly just glad to finally have someone else confirm. The chances of having two defective units in a row are extremely slim. Really liked the device otherwise, too, especially for the price.
I tested it for hours. I never got a disconnect on HSPA when I had that set. I just wasn't willing to live with that restriction.
Me as well!! phone is perfect for the price I paid out of pocket I had a BB gift card. I've been shopping for the right phone for a month now I've had about 5 phone from 700 to 200 bucks the expensive ones we're worth the price and the cheaper ones didn't feed my power craving I'm pretty happy with this one for the moment, thanks for the tip
This may be an AT&T SIM related issue.
I have T-Mobile and with my T-Mobile SIM I have no problems. I tried my friend's AT&T SIM, downloaded the APN, rebooted, and sure enough signal drops just like you're experiencing.
I'm having the same exact issue as previous posts with my Ultra. I purchased the unit from best buy the day it came out and using it on AT&T. I love the phone but the issue with completely losing connectivity is a bit annoying. Called customer service and they gave me the same website to fix software issues. Just curious as to why I'll be in same location without movement and then all of a sudden lose my signal.
I have the same problem using cricket wireless which is using att's network, lte signal comes and goes, this is becoming really annoying, is there a fix for this already, or should i return the phone
So I just got off the phone with Sony and they said I would have to send in the phone for repair leaving me with no phone. I've had issues before with phones and the companies just send you a new unit with a box and return label to send back defective unit. The rep said maybe my provider would give me a loaner phone.... Smh Looks like it might be time to leave Sony. Maybe I'll have better luck with the Lenovo Phab Pro 2 coming out next month.
Same issue here, right out of the box today.... Using AT&T reseller and I would have to agree that it is an issue as was mentioned earlier where the phone is somehow not able to fall back on to HSPA on a weak LTE connection so it just completely disconnects. Strange thing is where I am using it (at my desk in my office) I never had an issue of LTE dropping off with other brands of phones. As soon as I left the cell area and started using it at home or at another location further away I had no dropped LTE signals. I think Sony support will be useless unless we can somehow get past the standard support desk. They told me they have no higher support I can be directed to, that I would either just do a software repair (which I assumed correctly would not work) or send it in to service. Not sure what I am going to do at this point, cannot have my phone jumping out of service every 2 minutes during the work day. Any other suggestions would be appreciated.
EDIT: upon further review (using LTE discovery App) it appears that "some" At&t sites are having issues staying connected with LTE band 17 on this phone. I drove up to one of the sites the phone has issues with. It had a solid,strong signal within 1 block of the tower and band 17 still disconnected the radio completely. As soon as it reset and moved to band 4 it stayed on without disconnecting until I moved away from the site far enough for band 17 to kick back in. At that point it continued to disconnect every 1 -2 minutes until I moved the phone mode into HSPA preferred. I don't know what to say about this, band 17 works great on 2 towers within 10 miles of here, but some others and this tower causes the phone to go into a fit. Clearly the phone has LTE issues as any other ATT LTE phone on band 17 I have used in this area has always worked just fine. Anybody have an opinion on this???
I have what I think is the issue, now if we have any way to get this information to anyone who can actually do something about it. I have 2 sites by my home that the phone works flawlessly on LTE... no dropped LTE signal whatsoever. Here is the difference... they are band 17 ONLY sites where the sites my phone is unable to hold a LTE signal when the At&T site is broadcasting both band 4 and 17. That would explain why the rest of the sites around where I work do not maintain a signal either. We need to all contact Sony support and somehow get this information thru to them. The issue is the phone clearly being unable to handle a site broadcasting 4 and 17 which I think is a majority of them.

It's still not falling back in HSPA like it should. If it has difficulty with an LTE connection, it should not drop connectivity completely.

Agreed, but keep in mind that my XE ultra was 1 block from the tower with incredible LTE signal strength and it still completely shut the radio down and restarted. This is not for lack of signal but a complete inability for it to handle a band 17,4 tower. Although it would be great if it just moved into HSPA, that would mean your phone would be in HSPA 80% of the time, even when the LTE signal was completely adequate for the area. This clearly is a defect that makes the phone basically unusable (as it continually shuts the radio on and off) until Sony can figure this out. My concern... there is no way to talk to anyone at Sony that can do anything about this until they get enough support complaints directly related to this issue, this could take months not including the time they need to program an update and fix. Very frustrating.

Frustrated with this as well, hopefully sony fixes this problem more sooner than later
Received an update yesterday and I can't confirm 100% but it appears I haven't had as bad connection (popping in and out). I'm in Houston btw.
I got the update and so far phone has been working fine
The latest updates from sony fixed this issue.. so happy and enjoying it now
