I've been having this problem probably once a day since I've gotten the phone where my phone will lose data signal while switching between 3G and LTE and the only way to get data back is to restart the phone. Turning airplane mode on and off won't work either.
Ive had that issue too..but most of the time it switches back n forth no problem

I haven't noticed any data problems until today. I am unable to connect to 3G. We do not have 4G in my area.
These problems are probably bugs in the LTE System.

why should bugs in the LTE system affect 3G?
the 3G our phones use is not exactly the same as standard 3G unless you force your phone into EVDO 3G via the ##778 menu. which if you are not in a 4g zone I would recommend simply for stability. The 3G our phones use is basically a layer between 3G and LTE as I've had it explained to me.. I really don't know much else about it though, sorry. I'm sure someone else here can shine more light on it however.

oh that's really interesting. thanks for that little bit of info. had no idea.
Same problem with it dropping data signal and never coming back without restart. At least now i know its not a hardware issue
I've had the same problem lately

damn.. i was actually hoping this was a small problem with a simple solution... everything else about the phone is perfect except for this one problem.
Having the same issue here....when switching to cdma I get no 3G just 1X.....hope they find a fix soon
Sent from my HTC Rezound
same here guys. call Verizon and let them know. I think it helps if a bunch of us make them aware.
I've had a ton of weird data issues with the Rezound. I get 1x where i should get 3g, i get 3g where i should get 4g and i get nothing way too often.
I've only had this happen once with the rezound. Shows nothing but bars, no data can be used. Sometimes switching to 3g or 4g in lte on/off helps.
Had this problem intermittently on both my wife's and my bolts, completely agree its just a lte being a new tech issue.
I've listened to a podcast on how the handoff works and its definitely not fool proof.

phone will reboot and you should get 3G back
This changes your network from eHRPD back to EVDO Rev.A. For LTE phone owners, eHRPD causes 3G to die (most of the time anyway) when the LTE network has problems. Get back on normal EVDO and you're good to go.
^ from Jntdroid on another forum (not sure if we're allowed to post to other forums here) I'm not positive on where he got it from, but this is a capability of all HTC 4G phones
I've had occasional issues with being down to 1X, but even that was only during nationwide 4G network issues, definitely get in touch with VZW about that... not that they have enough sense to fix anything *sigh*
Data Connection slow to Acquire (3G/LTE)
If I'm on the subway, or somewhere with no service, then come above ground, I get voice (full bars) but no data -- it could take upwards of 3 minutes+ for data to come back up. Any thoughts?
I've been losing my 3G service throughout my city, being restricted to 1x so many times lately where I SHOULD be getting 3G!(4G isnt available in my area yet). It's really annoying...perhaps nexus isnt theeee only one...
^should I try calling and programing what the user implied? Again, I am not in a 4G area...

Same issue as you. I live in a 3G area only and my 3G drops out a lot. Even a reboot doesn't get it back. Not sure what to do :/
I switched from Verizon to Cricket, had my DX2 flashed at a shop and switched over Cricket. Everything works, but I rarely get 3G data. Usually it pops up for a minute or two, then disappears for a few hours again leaving me with only 1X.
Does anybody know the way to update Crickets PRL info? Or is there anything else I can do to get 3G connection more reliably? I know it isn't a signal issue, as it just simply doesn't work well anywhere whereas others using Cricket have 3G and good signal.

I'm sorry, but the name Cricket alone sounds solo, not sure how their network runs, but is this all you have? You can try calling Cricket, to manually activate your phone, changing our entering the codes manually...good luck, love to hear outcome..

Also, I have experienced the same issue on Verizon, mostly when connected to a Network Extender. Toggling my wifi on and back off (with a connection having been established) usually does the trick to force it back into 3G.

Cricket is a pay-as-you-go service in the Phoenix area and probably SW USA in general. It runs on Verizon's CDMA network, just typically given lower priority. However, I am basically unable to get 3G connectivity period. The phone has been flashed from Verizon to Cricket and activated and everything seems to work with exception of reliable 3G.
Mods please sticky this.
There's been several threads with people saying that they are getting intermittent slow or no data connections. Some people suspected throttling.
I did some digging around and found that it is a common issue on all ATT LTE phones. I have read up on various fixes, found one that worked, and will summarize it here.
Create a new APN that is EXACTLY the same as your current one with two exceptions:
1. APN: phone
2. APN type: internet
Save the APN. You should now have 2 APNs. Make sure that the original AT&T PTA APN is the selected one with the green dot.
What we've done here is replace the APN just for internet, and left everything else the same. If you try setting the type of the new APN for everything, it breaks MMS.
There are several dead spots in my town where I get incredibly slow or no data , despite my wife's iPhone working just fine. I made this change and now it works perfectly. Same top speeds for upload and download.
The only thing I cannot test is LTE, since I am not in an LTE area. From what I've read, this is an LTW APN so it should work.
Thanks. Works great and I'm in LTE area.
Very interesting.. thanks for the post.
Just for clarity, we're not to remove "internet" from the original PTA, right?
Edit: Oh, and we can name it whatever we want, I'm assuming? Or does it have to match the original to replace it?

You can't remove the original APN - it's not editable. Leave it as is.
You can name the new APN whatever you want, as long as the APN is called phone.
I am so excited to test this out. I just entered those settings and will report back at the end of the day with my results.
I'm in an LTE area as well and have been experiencing an issue where every time my phone goes to sleep google talk looses connection and I no longer get any push notifications for gmail or my exchange email.

The oddest part is that the indicator shows I am connected

Nevermind previous post....
Please note, PTA APN is required if you want to use LTE. Phone APN is for HSPA+. If you are in the area where there is no LTE service, this might be the solution for you as AT&T has a network issue ever since it launched LTE that LTE phones with PTA APN can't get consistent internet access when there is no LTE signal.
So, don't DO this if you are in a LTE area. Or else, you will be forced into HSPA+ network instead of LTE network you paid for.
If you select the phone apn yes....you will be forced into hspa. ..actually in my case it went to no cell connection at all.
There is a theory that simply having it there but not selecting it may help...which doesnt make sense but I am testing it regardless

that's basically what this is - having it there but not selecting it. its almost as if it uses it as a fallback when the PTA apn can't get connected in an hspa area. this would explain why my hspa issue is fixed and others can still connect to lte just fine.
This problem is quite wide spread when Skyrocket was first released. Can't believe AT&T still haven't sort this out.

then you did it wrong. make sure the original PTA apn is the selected one, not the new one. also make sure the new apn type is only internet. I had the same issue when I made those mistakes when I was first testing.
Did this and does not work as people have stated. Doing speed test before adding the apn I would get lte speeds. After adding the phone apn my speed test decreased considerably. This was with att pta selected as well.
ATT has to fix the connectivity issues. For myself, when I do speedtest on lte, it is very sporadic! It times out sometimes while doing speedtest. It's very annoying!

it works for those of us in hspa areas. i guess it isn't going to work for lte areas.
I did the fix and still got 17MBPS on speedtest. I got my mms working btw.
Hrm...i think peopke are doing it wrong. In an lte area, Added it per the directions and the connection issues are slighty better...not completely gone.
No difference in speeds. Lte is the same..hspa+ is the same

Hello,
I am coming from an Inspire 4g phone have been using the Not since its release date. I am having a similar issue with my Note that the Inspire had, but I am unable to work-around the issue the way the Inspire did.
My issue is that while my phone has great cell tower signal, my phone drops into Edge connectivity constantly. Prior to my Note upgrade, my Inspire would do the same thing, but I had a couple of work arounds I could do to lock back into 4G (HSPA+).
A) I could reboot the phone and the overwhelming majority of times it would go back to H+.
B) I could turn the mobile data radio off and then back on and again, the majority of the times, it would go back to H+.
C) The fix I used most often was to go into the phone dialer and dial *#*#4636#*#*. This brings up a back door to the testing screens and I could access the phone information section. In phone information, I could change the preferred network type and I would change from the default WCDMA preferred to either GSM ONLY or WCDMA ONLY depending on the area I was in. This not only work with near 100% success, it also locked the signal into H+ for longer periods of time.
Now that I have my Note, I have the same issue with the phone dropping to Edge service. However, when I try each of the 3 methods above, including *#*#4636#*#*, my phone stays locked into Edge. I can not get it to change.
I called AT&T about the issue and they explained to me that the phone will lock into the stronger signal, so if Edge is stronger, that is what I will get. I told them about my workaround with my Inspire and they could not give an explanation why it worked with that phone. I did talk them into re-sending the network information to my phone while on the call. They sent the information and while I was sitting still with full bars of signal strength, the phone miraculously popped into 4G service. I asked why it would change from Edge to H+ when they sent the network information since I didn't move to affect the signal and they could give me no explanation.
Does anyone have an idea how to make the Note ignore Edge service if H+ is available? If I can't figure this out, the Note is going back and I will stay with my Inspire 4G for now.
Thanks,
Roger

As stated, this is not available in stock rom nor TPC Note 2, which I am currently running. However, based on what I remember seeing on other Samsung phones, the *#*#4636#*#* feature I reference is supposed to do the same thing.
Thanks for the replies. Looks like the RAT feature is locked. Using the Rogers Radio seems to fix the problem, but breaks video playback at this time.
I found it an other thread, so I don't take any credit for it as someone else posted it, but I have confirmed it works on my Galaxy Note
*#*#197328640#*#* > debug screen > phone control > network control > band selection
You need to do this after each reboot though as it does not stick.
To work around this I have made a contact and only left out the last * in it, so all you do is use that as a speed dial and you are good to go
Hey everyone! So I've had this phone for about a month now and I'm pretty happy with it so far. Since I've gotten the phone, I haven't seen LTE pop up once (apparently CT has no LTE yet...) but this weekend I was visiting some friends in Manhattan. I know some parts of Manhattan have LTE. for example my friend has an iPhone (same carrier obviously) and he had LTE while I did not.. I made sure my network setting was on cdma/gsm/lte auto and I even went as far as typing in *#*#4636#*#* to check the radio settings. I did get the LTE symbol for like 10 secs but after that it disappeared and I lost service.. Another note to make is that I'm not on the stock apn setting because I changed it to epc.tmobile.com to boost my hspa+ speeds.
That's why. Lte uses fast.T-Mobile.com apn from what I'm aware of.

As the above posters mentioned make sure you have the fast.t-mobile.com apn.
BUT be sure you spell it right. LOL i made the mistake of spelling fast with fats and it took me 2 days to catch my typo. It would show the signal strength of LTE but not actually connect to it.

Haha that's so funny! One more question even though I wasn't on fast.t-mobile.com and was on epc.t-mobile.com i still wasn't able to see the LTE icon, any clue why? Thanks!
The only thing i can think of is that HTC / Samsung seem to have lower DB reporting of the actual signal strength compared to Apple.
Ive been in a discussion on other threads about how the signal indicator on my Note 2 and HTC One always seem to show low signal when LTE is connected.
Another person chimed in stating that they compared their HTC One to an iPhone 5 and noticed the signal indicator on the One shows 1-2 bars and the iPhone 5 showed full bars LTE.. Same T-Mobile Network phones side by side.
My rebuttal was simple. I downloaded an app that showed on both my Note 2 and HTC One a higher decibel reading then what my phone software was showing.
What leads me to believe this is with 1 bar i can still get 20+ megs down and 15+ megs up. Normally in low signal speeds would degrade.
I was also with Sprint on the GS3 and EVO LTE and the EVO LTE suffered from the same problems early on. They sent out several firmware and radio updates that corrected false and low signal readings and right before i left Sprint my EVO LTE outperformed the GS3 When / IF i could find LTE in Dallas on Sprint.
Give it some time. Im hoping they put more towers online and that devices get radio and firmware updates to perform better with the LTE that TMO is using.
I don't think the APN matters. I use the different APN for faster HSPA and I can still get LTE. I'll show you when I get home or in an area with LTE. LoL!! Also, in that very thread it was stated that changing the APN won't affect your LTE.
perhaps BUT if you misspell the apn then it wont be effective at all.
APN:fats.t-mobile.com you wont get an actual connection to LTE because its supposed to be fast. not fats.
This also happens if its the ONLY apn. If you have multiple APN it will revert back to another that works..
but this only happened to me so who knows..

It could be the radio firmware. HTC continues to update the radio with most releases fixing bugs..you should report this bug to HTC dev. Because I have the same issue NEVER get above 1 or 2 bars on LTE T mo

I just got the HTC One and flashed away Sense the very first day. Despite living in Chicago, the phone's signal has been pretty shotty and even dropped to 0 in areas where T mobile claims to have "4 bars". My girlfriend complains about hearing static in the background despite the signal being clear on my end. After speaking with T mobile customer service today, I was told it could be the phone or the whole rooting thing...not sure whats going on and I only have three more days to return/replace the phone. Anyone here experienced anything like this?

When it comes to service recognition by the radio and software of the phone, the apn doesn't matter. Think about the apn settings as joining a proxy server; if you notice you are just placing IP, web server addresses and port information in that settings page, and you must be already member of the network (have connection) for these settings to be relevant.
That is why if the apn settings are wrong you will still have service but not receive data.
The issue with one phone displaying LTE right next to another which is not (same provider) comes about how the software for the radio is configured and how well calibrated is the antenna of the phone and the radio processor... And a few other environmental factors too.
