Htc Zara CL network problems. - HTC Desire 601

This is my first XDA post, so please bear with me.
So I have an htc Zara CL (HTC desire 601) with flashed dirtyunicorns ROM. Everything is good, except my mobile data. Now I don't use data, but it is always on and there is no way to turn it off. Also, I get random drops where the signal has a ! Next to it and says roaming indicator off. Agh! Any help would be appreciated. Here's as much information as I know-
HTC zara_cl
Radio - 1.14.50.0516
rom - dirty unicorns (andrid 5.1.1)
I am rooted, s-off and unlocked bootloader if that helps.

I've been having the same issue with dipping reception. My brother has the same exact phone on the same carrier, but his phone is stock. With both next to each other, we get different readings for network strength. Also, the network will occasionally cut out without ever making it apparent, so you have to make a habit of changing preferred network types back and forth to make sure you don't miss calls or texts. As for turning off data completely, I don't think it's possible. I was digging around the settings for you to see if there was anything hidden, but came up with nothing. Unless you are trying to use data, transfers only happen between you and the network for purposes you won't be billed for (as far as I know).
These are among the mild infestation of known bugs with this ROM on this phone. Sadly, no more weeklies are popping up despite huge numbers of changes to the core of the ROM's framework and base software. I fear we may never get a true daily-driver for this hardware. If only I could go back to InsertCoin or stock...

[BUG] Persistent Data Connectivity Issues

Hey there,
I have had this issue since I got my hands on my Atrix but it still bugs me that the issue has never been fixed. Others also still have these issues, but I hope that with our talented devs, a fix can be found.
When connected to my home WiFi network, Internet works fine.
When I disable WiFi on my phone, Data won't reconnect and the H icon won't reappear.
When I walk away from my WiFi range, Data again doesn't reconnect like it should.
When using data, after a minute or two the Icon will start to show repeated attempts of uploading data when I click something, but will never download anything, causing my website or app to hang and eventually time out. This is oddly fixed by me going to my APN settings, editing Vodafone Australia (my internet apn) but not changing anything and then going settings > save. Causing data to disconnect and reconnect correctly. (most of the time)
This is very annoying. I can stay connected to data for a max of 5 minutes, and I know it's not the network as my friend with a GT540 Optimus can stay connected for hours at a time at the same place in the same conditions.
If any dev can help then it would be greatly appreciated (or if anyone knows of a fix), I am willing to help test anything created and also provide any logs that may help narrow down the issue (although I made need assistance in retrieving those logs as I've never tried) in addition, the mods used on my phone can be found below in my signature except the radio info which is 1.77.30P
You can contact me on this thread, PM or rarely in the freenode chat
Thanks for your time.

is there really nothing I can do to help? This issue alone is making me consider selling up and buying a SGS2 or Sensation, since I rely heavily on a constant data connection.
I guess my only option is to wait for CM7 and hope that fixes the issues I'm seeing..
Wifi connection at my house is a pain. It won't connect to it at all unless I go into the wifi settings menu and turn it on from there. I also have problems with it losing data connection when going into the Market or Navigation...which was pretty bad on my trip to Arkansas. I just thought it was my Atrix.
Personally, every Android phone I have owned has had glaring hardware/software issues EXCEPT my Inspire. I'm switching to Apple. *prepares to be flamed*

LOL, i won't flame you. Android vs iOS is the same argument as Windows vs MacOS.
It's a "Features" vs "Stability" trade off. Apple maintains better stability by cutting down features, locking things down and limiting usability <- not that hard to accomplish. Try to work in Windows 7 under non-admin account and without installing useless crap. You will be surprised as to how smooth and nice everything functions.
But for me, Android / Windows feature list wins by a large margin. I've only had one frustratingly buggy Android phone and it was a Droid 2 Global. Again, not Android's fault but Motorola's for releasing crappy software.
Anyway, if stability is your main goal, then iPhone is the phone for you
You might want to also try a Nexus phone (perhaps Nexus 3?). I've heard they are supremely stable. (never actually owned one )
p.s. I've seen a quote by someone on here, that half the fun from owning an Android phone is modding it. And for me that's 100% true.

Is that the right radio for your phone?
I thought the 30p was for AT&T only? Could this be your problem? You may need an international radio.
I know you have an unlocked AT&T, but I thought the radio was carrier specific, and not phone specific.
I could be wrong though. My wife tells me I am always wrong!

hmm that seems like a good idea, but can I even flash an international radio on an AT&T handset? Also Vodafone Australia uses the exact same frequencies that AT&T use except AT&T 4G is considered Vodafone 850.

Someone more technically minded with the Atrix will have to answer this. I thought the hardware was the same, so in theory flashing the wrong radio shouldn't do anything but give you data loss if it doesn't work. Then again, I am frequently wrong.

epic find. that's my post on an old user handle which I haven't bothered to change yes, I won this phone but so far it's been quite bugged. I originally thought that I was given a prototype/dev model since they shipped it before it was released but now I know that's not the case.

Weird 4G LTE problems

So my HTC EVO 4G LTE has been treating me very nicely.. great battery life and CM10 is smooth as ever.. the kernel I have is great and I get a 2.0 GHz overclock without problems. The weirdest issue has been haunting me lately. On CyanogenMod 10, I am unable to use the 4G LTE service that is located on a tower about 150 feet away from me at this moment. The issue is that while the phone connects to the service and I can call and text, for some reason data never works. I get 4 bars that I could only get from this tower, and looking in the phone information section of *#*#4636#*#*, I see that the tower shows up as LTE. Now it used to be that on Sense, I could turn on airplane mode, wait about a minute, and then connect to 4G LTE.. but now not even airplane mode can get me connected to it. There should be no reason that the phone can't connect to the tower because the signal, when connected, is very very strong. Does anyone know of any potential fixes for this issue? It's been haunting me that I'm located here in Dallas with a 4G LTE phone on Sprint next to a known working 4G LTE tower and people around me with Samsung Galaxy S3s and other 4G LTE phones are connected but I can't. Thanks for your help in advance.
By the way, I did search the forums and surprisingly no one has an issue similar to this in any of the topics that I checked.
Bump.

Did you post the issue in decks thread? That's where I would post, if that's the ROM you're on.

I installed the new radio from the OTA onto my phone and I thought it'd fix the problems but the problem was only temporarily fixed when I reflashed CM10. 4G LTE worked for a few hours.. but then after I went into a building, the signal dropped to 1 bar, turned on 3g, and call quality became utter crap.
I would post in deck's thread but I'm not sure the issue is specific to CM10.. I used a sense rom and for the first few hours of use it worked great and I would get strong LTE signal.. but after that I seemed to again be able to connect to the tower that's transmitting 4G LTE and in the network settings it would show up as LTE, but no data connection could be established.

May sound simple, but did u do a full wipe between roms? Factory reset? I know after going s-off I had to call sprint so they could send me an update to fix data and calls.

Yes, I did full wipes between roms including factory reset and system wipes. Only my SD cards are left unwiped.
I called sprint support today inquiring about that but the guy just had me go into ##72786# and reset my network connection settings.. didn't help the problem.. Any name to that update that I can ask them for that'll help me get it?

They should have recognized it if it was an error. So calling sprint won't do much. There's an app called network in google play store. Has the option to switch to different bands, or a lot more than any stock program will let u switch to.
Try switching from CDMA auto to Evdo/LTE or the other LTE options and roaming bands they have on there and see if it helps. Hopefully someone with a fix will see this thread soon enough. Only other thing I can think of is the ##4636# (digits may be wrong)and switch some settings in there.

Nothing of the sort fixes the issue.. I'm gonna try reflashing radios.
I'm on 1.15, S-On, HTCDev unlocked, CM10.I have the same issues.
When i reflash the kernel, LTE will work for several hours, and then I get the gray bars of doom. Oddly, I still get a data connection with some apps (Reddit Is Fun, etc.), even though the phone shows no data. It's been so frustrating that I've considered going back to sense...

Yeah that's exactly what happens to me.. and no matter my attempts to airplane mode the phone refuses to connect to 4G LTE data after a few days of reflashing.. So odd.
Just clean flashed deck's most recent build from IRC (9/19?) and I'm having the same problem as before. This time it didn't even make it an hour before LTE went away.
And after searching around, apparently we're the only people in the entire world experiencing this issue.

I.E. His statement still stands because we would still be the only people in the world having this problem..
I am honestly stumped as to how to fix this.. Sprint support can't help and I sat in the irc and people would tell me to force lte mode in network settings.. Doesn't work.. Because even though I get data connection.. I then lose the ability to call and text.
I tried paranoid, cm10, and aokp. I couldn't get lte on any of them. And phone calls were at max volume, distorting the speaker even, no matter where the actual volume indicator is.
Went back to a sense based rom and no problems.
1.12 panda hboot, s-off'd, with the new firmware.

I'm having the same Issue. Seems to have started with a Rev of CM10 around the beginning of September. I have been running a Sense ROM for the past few weeks, but I check in every so often to see if deck's made an update. Nothing has worked so far. Anyone have an update or solution to this problem?

I am having the exact same issue as you with the "Greg bars of death". I had good consistent 4g at one point in early September (possible unofficial 9/6 build based on saved speed tests) but not since then. I have also found that having LTE off gives me more reliable 3G data.

Join the club... it's the typical LTE connection issue with the EVO LTE. Its not your phone or updates. Even a 100% stock EVO LTE with all the updates has this issue.

[Q] Unstable data connection

I've had an odd issue which after many attempts, I have been unable to resolve. Constantly, since the day I bought my HOX+, it loses its HSPA connection, falls back onto 3G, then after a period of time, resumes HSPA. It happened on the stock rom, CM, AOKP, and my current Venom ROM.
It is not a signal strength issue, to my knowledge. I've had several other phones in this town, and I have never ever experienced this with any other phone, even remotely. While watching this issue happen, my signal strength remains constant -63 dBm 25 asu. TBH I don't honestly know what those numbers mean, but for anyone that can help, maybe you need them.
I have the international HOX+ with a Bell SIM card. I love this phone, but this issue is interminably annoying and is the one remaining thing that's keeping me from really enjoying the phone. Any assistance anyone can offer I'd be very glad. Thanks.
Change the sim card.. and try....not just the rom...

I have an international HTC One X on AT&T (Didn't want their version) and I see my phone go to 3G when it's idle but it goes to H right after I initiate something that requires data. Is that what you mean?
Oh, and does anyone know how to check if this phone is using HSPA or HSPA+. In the settings and by using the 4636 dialer code it doesn't say so. On my Galaxy Nexus it will say HSDPA:8.
Haven't tried switching SIMs. I don't have another one to try, but they're cheap, I'll see if that helps. Also, in the 4636 menu, it shows HSUPA 9, which I believe is HSPA+

Borked 1x antenna?

Recently I have been experiencing, like many others, difficulty maintaining my 3g connection. It drops out at random times, sometimes staying off for 18 hours at a time regardless of reboots, flashing different roms, resetting my phones profile or reactivating my handset.
One thing I have noticed though, is the fact that my phone never goes to 1x. Ever. It's either 3g or nothing.
Do my questions. Is there a way to test the function of my 1x antenna if it is indeed separate from the 3g antenna?
If they are not separate, is there a way to reset it in some way?
I am currently running the latest radios from The good Capt. Throwback, my thought was to downgrade them and see if functionality returns.
Any ideas on how to proceed after that would be appreciated.

ETA: running Jamie's latest PAC and have run PAC and RootBox almost exclusively. Stock kernel. No tweaks. Flashed latest radios about 30 days ago.

Jeezz...I had almost the exact same thing happen to me the other night...I had chalked it up to messing with a torrent app...but out of no where I lost my 3g connection, and it went to 1x...and the 1x would also cut out leaving me with nothing at all every 5 mins or so(the weird thing tho, is when the 1x connection would disappear I would lose the 3g symbol but in the network type it would list EvDo now...but I would not have any connection).
Naturally I was crappin my pants lol, I can't use the update profile feature on my phone, it's on Boost. So I went ahead and flashed the phone over again...Still the problem was there....So I did a factory data reset....still the problem was there....finally I went ahead and did the ##786# factory reset, flashed the phone again...Finally I was back on evdo like normal.
(BTW, my Evo LTE is now running 4.0.4 stock and there happened to be two of my friends here with their flashed to Boost Evo's, which were all running on EvDo with no issues...Plus I fired up my OG Evo 4g that is also on my Boost account and it was running on EvDo no problem whatsoever....so I knew this was some crazy issue with my Evo LTE)
I'm just glad the hard reset fixed it, I've been paranoid ever since though checking my network status, making sure I'm on EvDo lol.
Thanks for the responses. I've tried every reset I can find. Flashing the older radios didn't help either.
At this point, I'm just trying to figure out if the 1x radio is functioning. At least I wouldn't completely lose my data connection when the 3g drops out.
This happened to me when they were doing tower work in my area. Lasted a few days then I had 4g in areas I never did before.

I can only hope that's the case, Thick. It would be the best possible outcome.
By the way, thanks for the kernelly goodness.
It's the most likely cause, sprint has really been stepping up the rollout, in less than 2 months my lte coverage has practically tripled
could be eHRPD switching, I know deck got it all fixed up in the cm10 nightlies.....are you in a LTE area?
if not try setting mobile data to just CDMA and see if it sticks. I had that issue on the early cm10 builds where it would try and switch and just drop data completely.

My area in Jersey is on the short list for LTE activation in the short term, so there's a really good chance of this being the case.

My confusion comes from not having 1x coverage where I used to have it. Is that coverage dropped once LTE is activated? That would explain my issue.
I have read up on the eHRPD handoffs being an issue, but since I don't have LTE coverage at the moment I ignored that as a cause. I'll check out the newest Deck build and see if that helps anything.
Thanks for the help.

What is going on with Sprint Service

As some of you have probably read.
I gave up on the M9, mostly prompted by dropped calls, or calls going straight to voice mail.
I had the M9 replaced and gave it to my wife. It's been near perfect for her, she even dunked it and it's still running great.
My G4 is now doing the SAME thing. Although it has not dropped many calls, tons of calls go straight to voice mail.
Had a very important call this morning and even shutoff LTE, WIFI and Bluetooth and only had 3G on. And it went to voice mail.
The signal is not great, but should be fine for CDMA. Previous generation phones were fine (M8,M7, etc.)
I do see the signal bounce. Where it will be 3-4 bars one minute and none the next. The bouncing can be common in weak LTE (which is definitely weak).
But it's even bouncing with LTE off.
Even at home with two phones in the same location.
My wifes M9 will work, but my G4 will go to voice mail.
Where a couple months ago at home
My wifes M8 will work, but my M9 will go to voice mail.
Could their be something on the account that limits my phones? Like wrong bands or something. Not enabled for Spark but on a Spark Network.
As soon as Verizon gets the LG V10, I'm 99% sure I'm gonna switch. Don't know what else to do.
I don't really care for how locked down Verizon is, but I need a working phone.
This problem happens at multiple locations.
Any ideas appreciated.
I know this isn't specifically an M9 issue, but I know their are more experienced folks around here that might know something.
It is related to M9 TYPE phones though (Spark Generation 2-ish phones). It started when I switched from M8 to M9.
Upgrading my wife from M7 to M8 went fine and from M8 to M9 went fine.
Upgrading me from M8 to M9 went south and from M9 to G4 went south.
All SIM cards cam with respective phones.
All bought new.
All S-Off and/or rooted.
I may have found the answer. Read this !! It has to do with having WIFI on and phone going to sleep. Which is exactly what happens on G4 and M9.

I disagree...I'm using the opposite settings that he is saying to use & I've never had this issue (that I know of). I don't make alot of outgoing calls...most are incoming...I also have my work cell fwd'd to my M9 so I don't have to carry 2 devices...I'm on Wifi a majority of the time, I get calls & texts all the time w/ no issues...the only thing I have checked in Advanced WiFi is Wifi Optimization, Keep Wifi on during sleep set to always
Fix
------
The fix is to not have Wifi on when the phone is idle/sleep. change your Wifi settings below to the screenshot below.
Settings -- > Wifi -- > MORE -- > Advanced -- > "Keep Wi-Fi on during Sleep = Never"
I also have "Network notification" and "Always allow scanning" enabled.

Sprint did (in my opinion) a very poor job with how it handles calls. One of my favorite phones was the evo LTE which not only could do LTE and a call at the same time but if you weren't in 4G it could do SV-DO and work on 3G which it actually worked very well. Especially at the time when I had that phone, I hardly had 4G anywhere so being able to use data at the same time on 3G was great.
That said, that feature didn't stick around long. The m7 had a separate radio for LTE & 1X meaning you could surf at the same time because it had separate radios. This couldn't do 3G which was a step backwards however 4G was becoming more mature.
Fast forward to today and with your modern tri-band device while it supports multiple bands that the previous phones didn't, most people have no idea what that means they usually assuming if it's a 4G phone well then it's just that how is any different.
I have had plenty of people complain to me about calls going straight to voicemail or signal issues. Rather than having separate radios, Sprint just uses CSFB Circuit Switched fallback so when a call comes in, it lets the phone know via LTE and immediately switches back to 1X to grab the call. That said it's by no means perfect especially in a bad signal LTE area can cause issues. When I'm at home or work I usually set my phone to CDMA only since I have wi-fi there is no advantage to be on LTE, causes issues with calls coming through and wastes battery. Most users have no idea about what is actually going on so it's hard to explain to a friend why when a caller calls them, the caller might here 5-6 rings before the phone even goes off. Sprint's LTE signal frankly sucks in most places I go, even right next to the tower sometimes you won't get full signal.
Anyway if your wifes phone works fine in the same spot as your G and you are doing all your testing off of LTE and still having issues that tells me either you have a bad radio again or something is provisioned wrong. I would put the phone back to stock, reset the radio and reactive the phone then do some testing with calls off LTE again. If you still have issues at the point, I would swap the phone. My M9 is pretty good with CSFB, I haven't had too many issues with it but really I think it's a very poor solution how it works especially when your in a fridge LTE area with the phone bouncing in and out of LTE.
Once the network goes all LTE (god knows how long that will take) I think this will be a thing of the past but for now CSFB now it's here to stay. I don't see Sprint ever going back to separate radios like the previous gen phones as they would more likely be focused on voice over LTE instead.

I don't make alot of outgoing calls...most are incoming...I also have my work cell fwd'd to my M9 so I don't have to carry 2 devices...I'm on Wifi a majority of the time, I get calls & texts all the time w/ no issues...the only thing I have checked in Advanced WiFi is Wifi Optimization, Keep Wifi on during sleep set to always

It has not failed in 5 days since I flipped it.
It may depend on the WIFI it's on, IPV6 etc. I don't know.
I think this may have started the same time MMS started failing for SOME folks if WIFI was enabled. Disabling IPV6 on WIFI was a work around (which is disabled on your ROM).
But not everyone had this issue and depended on their router.
So their is weird sh$t happening due to Android changes.
I think this issue is related and not everyone runs into it.
I have had WIFI Calling setup, but disabled it on both M9 and G4 (because it's extremely unstable on every phone I've tried).
Not sure if that is part of it. Like my account knows it's WIFI Calling capable. But my wifes never had WIFI Calling setup, she also does not run WIFI at work. She's never had the problem (even with the same phone I had problems with).
Again I don't know the exact details, and this is not a fix. But disabling WIFI when asleep seems to have stopped it problem. But I need to go a bit longer to be 100% sure.
I've seen similar threads on many phones and carriers and many start off saying "Problem started with 5.x.x OTA update".
I think I was close when I thought it was the optimizer. And before I found that thread, I was testing with WIFI completely off (which also worked).
Something is a miss and there may be more "options" to cause the issue.

Sprint did (in my opinion) a very poor job with how it handles calls. One of my favorite phones was the evo LTE which not only could do LTE and a call at the same time but if you weren't in 4G it could do SV-DO and work on 3G which it actually worked very well. Especially at the time when I had that phone, I hardly had 4G anywhere so being able to use data at the same time on 3G was great.
That said, that feature didn't stick around long. The m7 had a separate radio for LTE & 1X meaning you could surf at the same time because it had separate radios. This couldn't do 3G which was a step backwards however 4G was becoming more mature.
Fast forward to today and with your modern tri-band device while it supports multiple bands that the previous phones didn't, most people have no idea what that means they usually assuming if it's a 4G phone well then it's just that how is any different.
I have had plenty of people complain to me about calls going straight to voicemail or signal issues. Rather than having separate radios, Sprint just uses CSFB Circuit Switched fallback so when a call comes in, it lets the phone know via LTE and immediately switches back to 1X to grab the call. That said it's by no means perfect especially in a bad signal LTE area can cause issues. When I'm at home or work I usually set my phone to CDMA only since I have wi-fi there is no advantage to be on LTE, causes issues with calls coming through and wastes battery. Most users have no idea about what is actually going on so it's hard to explain to a friend why when a caller calls them, the caller might here 5-6 rings before the phone even goes off. Sprint's LTE signal frankly sucks in most places I go, even right next to the tower sometimes you won't get full signal.
Anyway if your wifes phone works fine in the same spot as your G and you are doing all your testing off of LTE and still having issues that tells me either you have a bad radio again or something is provisioned wrong. I would put the phone back to stock, reset the radio and reactive the phone then do some testing with calls off LTE again. If you still have issues at the point, I would swap the phone. My M9 is pretty good with CSFB, I haven't had too many issues with it but really I think it's a very poor solution how it works especially when your in a fridge LTE area with the phone bouncing in and out of LTE.
Once the network goes all LTE (god knows how long that will take) I think this will be a thing of the past but for now CSFB now it's here to stay. I don't see Sprint ever going back to separate radios like the previous gen phones as they would more likely be focused on voice over LTE instead.

I'd blame gremlins yes, weird sh*t...and yeah, we still have ipv6 disabled in ROM for wifi

I know about the call switching for LTE and it sucks. But that was not it. I tried CDMA only and it did not fix it.
Disabling WIFI while sleeping is still working. Not one call has gone to voice mail at work in over a week. It used to happen 2-3 times a day.
I HATE disabling wifi while asleep though. I'd like to still get to the bottom of it.
I think some how it is doing something over WIFI when a call comes in, if WIFI is available. But when the WIFI is in power save mode something gets messed up.
The problem started on OMJ's ROM with IPV6 disabled. So it's not that.
The only thing common is Lollipop, Sprint and my WIFI locations (and a modern single radio triband phone).
I'd like to try getting "WIFI Calling" capability off my account. I think once you set it up once, it's enabled automatically on my account.
I will also say, if I do enable WIFI Calling, it's terribly unreliable. Maybe that's a hint.
The WIFI signal is solid and no issues using WIFI itself.

Having Wi-Fi calling provisioned on your account is just that, it just means if you enable wi-fi calling that your phone has the green light to connect and move forward with the server. That said if you keep wi-fi calling off the fact that it is still provisioned on the account doesn't affect anything at all if the service is not active.
If you only solution is disabling wi-fi while sleeping something in the rom is borked. Return the phone to 100% stock, hard reset it (including the radio) then try using it again. While again CSFB isn't perfect, if the phone is CDMA only you just shouldn't be having this kind of issue. If your not having issues with other phones in the same area with calls going to vm, you know it's not the network and something with the phone. If it does this on 100% stock after a re provision then you have a borked radio and the phone should be swapped. Which I have seen borked radios before, the wi-fi radio in the phone is totally separate from the CDMA/LTE radio.

Did that, returned to stock, same issue. Got Another M9, same issue, got a LG G4 same issue. Just signed up for T-Mobile (have not canceled Sprint yet). Two LG V10's. T-Mobile just announced a huge expansion on their network to cover areas that I needed with LTE (Sprint roams 1x Lakes Region and North in NH).

Not a bad play, Sprint's Network has come along way in the past few years but with CSFB and a crappy LTE signal is most places they still have a lot of work to do. One of the reasons I stay is my plan and they are pretty friendly towards rooting/unlocking for the most part.

The V10 was awesome. T-Mobile was extremely good at My work, My wifes work, Home and all places between. Speeds were 4-8x faster (seriously) than Sprint. Simultaneous Voice and Data VoLTE.
But what the map showed up in NH, didn't match reality at all. Sprint is pretty dismal too, but they at least Roam and you can get 1x or 3G from either US Cellar or Verizon.
But T-Mobile had nothing in the areas Sprints Roams. So I'm sticking with Sprint for now.
I've concluded it's a combination of weak locations, the requirement to switch from LTE to CDMA for calls, and something around that is complicated by WIFI while asleep. Shutting off WIFI or shutting it off while asleep definitely improved things but didn't eliminate it completely. Both phones (M9 and G4) are Qualcomm chips and probably have similar Radio Firmware. But it's overly complicated due to Sprint being a bit behind the ball with VoLTE.
I agree Sprint is not quite so tight on locking things down. T-Mobile is the least locked down, then Sprint, then AT&T then Verizon. I know Verizon would perform flawlessly. But the combination of expense and being so locked down keeps me away. T-Mobile price was really good 2 lines 10GB each, with Carry Over and free Music/Video streaming. And the V10 already had TWRP on day one. The G4 on Sprint does not have TWRP and probably never will. It is rootable, barely.
I convinced my Sister to switch to T-Mobile because she wanted an iPhone and I recommended she not Jail Break it. But she wanted Tether (I was rooting Androids on Sprint for her). She is very happy with T-Mobile. And she generally stays in Eastern MA.
We'll see what HTC does this next time around. But they really need to step up their game. The reception issue really isn't an "HTC" issue. It's a Qualcomm/Sprint issue in my opinion. It's a kludge and I think Sprint is the only one with this kludge.
