tmobile lte issues or phone issues - T-Mobile HTC One (M7)

For the past week I've been having problems with my phone seeming locked in "wcdma preferred" mode despite it being actually set to lte/cdma in Phone Info menu. I'm in San Francisco and my daily commute path is completely blanketed with lte, and I have never had any problems connecting to lte until this past week. Usually as soon as I arrive in SF on the train, my phone immediately connects to and stays connected to lte. But at around the time tmobile rolled out their new plans (March 25ish?), my phone has been connecting to hspa 4g and remains on hspa until I force a lte connection by going into phone info menu (*#*#7696#*#*) and choosing lte only. This is particularly irksome because the 4g signal is only 2-3 bars while the lte signal is a full 5 bars. For whatever reason, my phone is clinging onto the hspa connection and passes my signal from tower to tower without actually passing it up to a lte tower. Once I force a lte connection, my phone will remain on lte and will pass back and forth between lte towers as it did before.
Anyone else notice this happenning recently?

Try setting it to gsm/wcdma/lte auto under settings -> mobile data -> network mode.

The gsm/cdma/lte auto setting is the default setting the phone shipped with, and changing it back to this didn't solve the problem. I use lte/cdma because I wanted to eliminate edge bands altogether since data is practically unusable when connected to edge, and the phone has an annoying tendency to fall back onto edge prematurely.
During the times affected, the phone seems to be locked onto the "wcdma only" setting, regardless of what was actually being selected.
I called tmo a few times and the issue seems to be resolved now. I'm certain it was an issue on their end, probably some software provisioning problem that came up when the new rates rolled out. For what it's worth I am on the now grandfathered $20 unlimited data plan.

I'm still trying to understand what T-Mobile was thinking when they changed their plans. Way to keep themselves super competitive.

[Q] Phone prefers 3G to 4G??

I have noticed that my phone seems to prefer 3G data to 4G where I live. (I'm in the Stow, OH area for those curious)
At first I thought I simply didn't pick 4G up at my house because I've never had the strongest 3G signal here either. But if I go into the Phone Info and switch the radio to "LTE mode", it switches to 4G no problem.
For some confirmation that the software wasn't being glitchy, I did a speed test and got ~5mbit down (like I said, I may not have the best 4G coverage... I get upwards of 18mbit when I'm in the Akron area). And for additional confirmation, I placed a call and was also able to simultaneously surf and do another 5mbit speed test. So it is definitely connected to 4G.
For more experimentation, I switched it back to the usual "CDMA + LTE/EvDo auto". The icon switched to the 3G symbol. I then tried placing a call, and I was able to simultaneously use data, but it was clearly 3G speed. So it seems it used the 4G radio for the call, but the 3G radio for the data (weird).
So, I'm wondering if anyone else has noticed it this kind of behavior? Perhaps in the fringe coverage areas this will be most noticeable.
My phone dose this too. I think its poor 4g service and stuff. Im sure it will inrpove eventually
Interesting...
Now I put it on the "CDMA Auto (PRL)" option. speed test indicates 3G speeds. But then I place a call, and the call AND data are both working-- at 3G speeds. So maybe this was what was happening on the CDMA + LTE mode I selected before.
It appears Verizon has some sort of simultaneous 3G technology now?? I wasn't aware of this-- certainly about time, though.
But my initial conclusion does seem to be true-- it's preferring the 3G coverage to the 4G coverage. Perhaps this is a battery life decision. Or something else completely weird is going on.
Either way, I'm plenty happy with the phone.

problems with re-connecting to 3g after dormant/wifi try this if in LTE launch city

I have been having problems with re-establishing a 3g connection after either being on WiFi or after a phone call after checking settings my phone was set to LTE/CDMA in the setting under mobile network I have sense changed this to CDMA only and now it connects automatically what I am thinking is happening is because Houston is a launch city is that it is connection to the LTE tower but won't connect because it is getting the command not to since the towers aren't live. It appears that the phone isn't releasing the LTE connection like it should. I am not sure if this will affect people not in the 6 core test/launch cities but I am thinking it is here.
On a side note since doing this I have noticed a faster 3g connection.

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.

I'm more skeptical than you, trust me, but it would explain how so many people get the same problem with replacement handsets, as that piece is often not replaced
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.....

LTE issue with multiple ROMs and radios. Should I get a new SIM?

I used to get LTE around here with this phone. Since about a month ago, things have gotten weird. If I use LTE/cdma/evdo mode or global, it just goes to 3G and never connects to LTE. If I go to LTE/gsm/wcdma, it gets LTE but no voice or text (which makes sense because Verizon isn't GSM). The LTE performance also seems really bad in this mode. It seems as though 3G is somehow prioritized above LTE, so if both are allowed it defaults to 3G. Manually switching APN's doesn't help. If I select "LTE - Verizon Internet" it doesn't connect to data and then after about 30 seconds goes to "EHRPC - Verizon Internet " and connects to 3G. Similar results on multiple different ROMs and radios.
I'm wondering if the SIM card could somehow be to blame. If I go to the Verizon store, will they give me a free SIM despite having CM on my phone? Don't care about warranty, phone is over a year old.
Are you on a custom or stock Rom? Is there a "Global" setting under networks? That's what my s4 uses. I don't think it could be your SIM cause if it was you wouldn't have any signal at all, not just 4g.

Sprint/T-Mobile LgV60

Is anyone else whos on sprint/TMobile having issues where the phone cant decide wether to connect to a sprint or TMobile tower? When im at my home i have a very weak TMobile 600mhz signal and a strong sprint band 41 signal due to the magic box. I also can pick up the band 25 signal the box uses and my phone refuses to just use the stronger faster sprint signal. It absolutely insists on using the TMobile signal. Is anyone having similar issues? Even on wifi its causing network interruptions so i have to reload a page several times to make it use the wifi.

Mine jumps a lot but never connects to the magic box. I don't think it's enabled for B41? I have a Pixel 3XL that I activate (and deactivate my V60) when I'm at my camper which is where my MB lives.

Mine works with Band 41. Its a big one in the nearby city. It works with all sprint and TMobile bands. Its just prioritizing TMobile bands over sprint ones regardless of signal quality

I have no idea of this is related but.. I'm on T-Mobile, with T-Mobile home internet as well, and for the last several days my phone is having issues connecting and the home WiFi is doing the same thing. I'm in a rural area so my signal is weak, but it's been fluctuating WILDLY since the merger and sometimes it does seem like my phone is struggling trying to decide what to connect to. There's definitely something going on with the network at least in my area for the last 2 weeks for sure

Sounds like this will be happening until the transition is done/5G is more widespread. These are TMobile models. When mine was first turned on at the store it had the T-Mobile splash screen. The ability to access sprint towers was added via software update post merger. I figure once the 600mhz band is fully rolled out the issue will go away as a result of the signal being strong enough.
