LTE connection problems - Sony Xperia S, Acro S, Ion

My Lt28at(h) shows that it is connected to the LTE:13 system but the data traffic is weak at best, some apps works at right speed, but others, play store, browser and a few others, really don't function or tell me there is a network error to even to make sure that I am connected. I am on net10, I have recently reset the phone, checked and double checked the apn, I am at a loss. (As for play store, cannot revert back to "factory settings" as it will only let me force stop and disable, same with play services)

who do you have service with? i've been experiencing the same thing with my phone and i'm on straight talk with the at&t towers

I'm with net10 (both net10 and straight talk owned by tracfone) on att towers as well, I have flashed and reflashed all 3 variations of the jb baseband with no avail as well as a full reinstall. any suggestions would be greatly appreciated.

must be a network thing... as i've flashed different roms and still had the problem.. i have to pay my bill tonight so i'm going to see if when they refresh my data if that changes anything

[Q] [SOLVED] T-Mobile G2, no service anywhere, error while searching for networks

I've been struggling with a problem that I just solved in a stupid way so I'm posting to help other googlers.
As I was using my phone recently, I lost service like I had gone into an area devoid of towers, but service never came back. I verified that another TMobile phone (similar plan) found towers and service just fine. I tried everything I could think of from upgrading Cyanogenmod and the radio to reverting to the stock firmware. No matter what I did, the phone would not get signal. When I went to Settings -> Wireless & networks -> Mobile networks -> Network operators I would simply get "Error while searching for networks".
It turns out that the SIM card had seen the end of its days. I went to the TMobile store and had the SIM card switched out for a new one (free) and everything worked again.
The explanation I was given was that old "legacy" SIM cards sometimes will just stop allowing you to connect to the towers with no other symptoms.
TL;DR: If your TMobile (maybe other carriers too) phone isn't connecting to the towers anymore, don't panic. You probably need a new SIM card and you can probably get one for free.
Seeing the exact same problem in the last few days
Found your post by googling the error message - I've got the exact same situation on my G2, the behavior started this last weekend. The phone sometimes connects but is very, very inconsistent. I'm missing almost all text messages, or getting them up to a day late. I guess it's off to a t-mo store for a new SIM card if this doesn't stop. Funny thing is this phone was purchased with a (supposedly) new SIM card - hard to call it "legacy".
Thank you, I just stopped getting service today randomly and nothing I did could get it back. I went in to panic mode and was flashing and wiping and everything I could think of then I saw this post. I didn't think it could work but sure enough it did.
way to be....i learned my fact for the day.
mine just bit the dust.
called t-mobile and they suggested a new SIM as well.
ah well
I had the same issue and after doing tons of troubleshooting i seen that there was a space right under the keyboard that was fully flush with the phone. I lightly pressed until both sides snapped back into place and full service returned. So if you have this issue check to see if there are any spaces open and snap it closed.

Mine has been doing this sporadically, it comes and goes and sometimes I cannot get it to find a service provider. I have to keep doing it over and over and over. Sometimes I have to set phone down and come back in a few minutes to do it again and it finally shows a provider.
The question I have is if you take your phone into Tmobile store to have sim. card replaced do you have to revert phone back to stock G2? Will they say something to you if you are rooted and running CM?
This problem happened to me too and a SIM swap fixed it. They don't check if you are rooted- they might ask you to reboot and change some settings to rule out the obvious stuff like airplane mode, correct carrier, etc.
Maybe not same issue, but also have a soultion for similar issue on G2X
Maybe I didn't have the exact same issue, but I had the exact same symptoms, so throwing my solution up here for other Googlers trying to troubleshoot this as well...
I actually have a G2X, went to Canada where I disabled roaming data and used the t-Mobile wifi calling stuff primarily...
When I got back home to the USA, I couldn't get a signal, but I also didn't have the little x next to the icon... When I went into my settings, I couldn't seem to get the "Use 2G Network" setting to stay off, and of course I couldn't make calls or anything over the mobile network...
So I figured I just needed to force the phone to register on the local network, maybe all the roaming got it mixed up or something, but when I went to the "Network operators" setting, I couldn't "Search Networks" and "Select Automatically" didn't work either, I kept seeing the error "Error while searching for networks".... spent some time playing with libril.so and friends, but it made no difference.
Anyway, long story short, it turns out that there's a setting in the T-Mobile "Wifi Calling" app under "Connection preferences", if you select "Wifi Only", it applies to your setting all the time, even when wifi is disabled, disconnected, and even if the "Wifi Calling" app is disabled too !! So just change that setting back to something else when you're done requiring that behavior and everything will work again, Yay!

I can verify that this is the solution that works. I have the LG G2 w/ T-Mobile. I hadn't had any problems until today. Stumbled upon this thread after the T-Mobile chat support couldn't help me. Went to System Settings and turned wifi calling off completely. Back in business.

[HOW-TO] Get a Data Signal While Roaming

Background:
Ever since I've had this phone I couldn't get a data signal while roaming in areas where I knew one was available. Old phones would get data while roaming without a problem.
The Epic Touch would just give a notification saying "you have lost data connectivity" or something.
I understand certain Sprint roaming areas just plain don't have data available. This howto can not fix that.
What this howto does help you do is get a data signal while roaming in areas where a roaming data signal is available.
Credit:
This was apparently discovered by someone on the sprint forums, and I found a reference to it on the Android Central forums, so I do not know who credit goes to for discovering this.
What to Do:
It's best if you are in a roaming-only area to test this, or if you can force roaming. You'll also need to be on the stock kernel (rooted is fine) so you have the ability to update your Profile.
Let's do that now. Go to the Settings menu and tap About Phone - system updates - update profile and wait for it to complete, then tap ok.
From the home screen, tap Menu - Settings - Wireless and Networks - Roaming - Roaming Settings.
Un-check all options here (voice and data for both domestic and international)
With no boxes checked, tap the "Data" box under domestic roaming. Tap only this one, not voice.
You will get a box asking you to confirm. Click yes. This will then automatically enable voice as well.
Another pop up with a red box will ask if you really want to use data while roaming. At this point you can tell it to never ask again and click Roam.
Now you can use data while roaming where it's available!
Update:
after trying this multiple times to verify it works, occasionally the final pop-up with the red box disappears before you can read it. I was able to long press the home button to show recent apps, then tap the "Data Roaming Guard" app. Then I could tap Roam.
This is critical for me as sometimes I am in roaming areas for work and I need internet and this phone is the only access I have. Now I can use it!
Report back with any corrections or feedback. Mileage may vary.
I don't know if it's necessary to update the profile. I have that step in there because that is the sequence I used. If you try it without updating the profile, let me know. This would allow people on a custom kernel to do this too.
I spent an hour and a half with Sprint yesterday on the phone trying to resolve this. They turned me over to new reps three times (including to the international support department) each one not aware of my issue so I'd have to explain everything again.
Finally I started digging on the web and found the tip on AC. Took me 2 minutes.
DOH! Stupid Tapatalk.
Mods, please move to General. Didn't mean to start this in development.
Thanks for sharing this. I will try this out.
Sent from my PC36100 using xda premium
I have the same issues. My girlfriend has an EVO and she will have data while roaming, and I wont. Even if were right next to each other.
Thanks, this worked great for me & did not have to update profile. I am on stock rooted deodexed rom.
Worked for me! Thanks, that was very annoying!
thanks! now i can play wwf at work lol
I did this awhile back when I saw it on the AC forums. I also read this phone cannot roam on PCS networks because of a limitation in the radio so there still may be times it won't roam when other phones will.
Greetings All!
I was able to make roaming calls before; but I followed these instructions and now I can use roaming data as well. Fortunately Atlanta is a pretty good 4G metro area so I rarely need to use roaming data. Usually either 3G or 4G is available. Nonetheless it's nice to have the option.
FYI I forced roaming by using the Roam Control app and have verified that for the first time with this phone I have a nonzero "Sprint 3G Data Roaming" entry in the detailed usage screen on the Sprint website.
Many thanks!
Cheers, Henri
Ok, glad this is working for people! I know it was the biggest gripe I had about the phone by far.

Agreed. And such a simple solution. Thanks again.

[Q] Losing Network is Making Me Crazy

I've had Background Data set on restricted on a number of apps for several months with no problem. Specifically, Play Store and a few others. Recently, I've started getting error messages when trying to launch Play Store saying that Background Data needs to be enabled. This is even when I'm on both strong network and wifi signals (and also set on network preferred). All of this is intermittent and if I re-enable background data it might - or it might not - connect. Until I reboot.
Also, (and this has nothing to do with background data restriction) when I'm in an area with strong network coverage, if I try to launch a web browser, it will often pop up with a bunch of ISP icons ( ATT, Comcast, etc.) saying that I need a wifi connection. This is outside with no neaby wifi and a strong network signal. And - my wife is standing right next to me with the same phone and none of these issues.
Phone is not rooted and no weird apps.
No problems with voice or text
Did a hard reset. Spent Waaay too many hours on the phone with Tmob. Got a new sim card.
Tmob agreed to send me a replacement but it's on like a twelve day back order.
Anyone have any ideas on what's going on with this phone? - Thanks
Anyone? Please?

Mobile Data stops working

Hello,
I live in an area (like many of us) there T-mobile service isn't that great. I daily drive through areas with zero service and I have almost no service at my house so we utilize WIFI Calling.
I have been finding for the past few months that when I return to an area of good service (phone showing full bars of 4G or 4G LTE) that I cannot move any cellular data. If I reboot the phone then everything works again for a while. I have tried to toggle into airplane mode and back but this does not help, only a full reboot helps.
Does anyone else get this? Its very annoying to have to reboot the phone when I need to use cellular data. Appreciate some input. Phone is NOT rooted and running the latest available software from T-mobile

It happens all the time for me. I've not been able to figure out why it happens, but I've seen some speculation in other threads where people think it can break when switching between H+, 4G, LTE, etc. Some people have reported that switching to airplane mode and back fixes it, but it doesn't work for me. Only a reboot will fix it for me.
Here is another thread with some discussion on it:
http://forum.xda-developers.com/galaxy-s6-edge/help/mobile-network-data-connection-drops-t3097605
Thanks for the response. I'm not happy to hear it appears to be happening to everyone. I wonder if any of the carriers have reported this to Samsung?
I cleared the cache partition on my phone 2 days ago and I've been good since...that doesn't mean it fixed it but its been a while since I had 2 good days!
THIS HAPPENS TO ME OMG!!! I thought I was going crazy... it happens quite often in NYC where we travel by subway underground... Switching to Airplane mode then back indeed fix it majority of the time, but it doesn't work sometimes...
Also, this happens when i am on Wifi for extended period of time, and then leave WiFi, the phone will show 4G LTE but wont' push any data.
Going into Phone status will show that you have no IP Address...
edit: btw, i've done an exchange with Tmobile, and still happens on the phone, Swapped SIM card as well, doesn't solve the problem. T-Mobile ran diagnosis, and found nothing wrong. I suspect it might be T-Mobile's network configuration...
Also, I can almost 100% reproduce this when I am playing a game that requires periodic connection (like loading acount info), and then playing in the subway while doing data connection between subway station (we have internet at the station, but not in the tunnel) will break my 4G LTE data connection...
