o this is weird, I just got back from a vacation in CA, back home to Portland, or and I have no data what so ever.
Been on Viper's rom for a while. I know Portland just got LTE like this week, not sure if that has something to do with it? Any suggestions? I already reflashed the rom and no dice
Try changing network mode to GSM/WCDMA Auto (or any of the other settings without LTE) and see if you get data.
What build of Viper? And what network icons? I've found the AT&T icons cause more trouble than they are worth. Almost any other ones cause less troubles. If using the AT&T icons, reflash using the stock icons.
Sweet that worked thanks. I did choose ATT icons, I will reflash right now with stock icons.
Hopefully that will make it so I can have LTE without issues, but for now changing the network mode has me back in business
hmm still can't get LTE, I tried putting in a new apn per the insturctions in the AOKP thread, but it still loses data when it switches to LTE
I'm not clear, are you on AOKP or Viper now?
If still on Viper, did you try to reflash the ROM, picking the stock network icons this time. You can "dirty flash" and keep your data.
If you are still on Viper, and on the AT&T icons, I believe changing the network icons actually changes the build.prop, and for some reason this screws with LTE, and simply changing the APN settings won't fix it. Not sure why this is true, its counter-intuitive, you would think the AT&T icons would work better on the AT&T network. But I don't know the details of how the build.prop gets affected by the network icons.

Flashed CM7 the other day (thanks again for the help Carmon!) and love it. Only issue I am having so far is...I've been unable to roam. I live in a fringe area, and normally roam on Verizon towers at home. I attempted *228 several times (while on US Cellular), and the recorded message (voice) states that the update was successful, but the message on my screen says "activation unsuccessful". I am able to make and receive calls and send messages, etc...but the phone will not roam. I have networks set to automatic, and national data roaming enabled. Any ideas?? Anyone??
The screen always says unsuccessful, it's a known glitch. Try setting roam options to home only or whatever, sometimes they get mixed up in the process of building and fixing other stuff.

Appreciate your response! I've tried every setting. Home only gives me US Cellular signal. When set to "Affiliated Networks", the setting will not remain there, it resets itself to Home only. When set to "Automatic", it catches US Cellular signal, but does not roam when there is no US Cell signal.
Surprised nobody else has this problem...
It may be a issue in which we need to go all the way back to stock and do the ADW fix.
Yeah possibly... scarmon do you have that to post? Ive never had to do it and I never copied it down...

I know how to do it but not sure on the names for everything until I'm in there. Let me see if I can find the thread with the.video on it. If not the OP can IM me. He has my Gtalk and I can walk him through it if needed.

Seems that fix is for phones that are always roaming. Is it known to work for the problem I'm having also (no roaming)??
Just got done flashing back to stock and completing the ADW fix. Flashed back to CM7...still no roaming. Tried every setting and every combination of settings with NO luck.

That's really odd... are you sure you're in a roaming area? The phone wont roam if you have uscc signal.

I am in a roaming area...as I mentioned above, I live in a fringe area, and my phone (usually) constantly switches between US Cell and Verizon. Now, it does not switch...it just goes from US Cell to NO service.
On another note, since I re-flashed, I am not receiving sms. And when I send sms, they are blank???
When you went back to stock did you flash the EH09 Build or did you flash EE19.
Edit. Didn't mean to double post
I did a full flash back to stock Froyo since I had the files already...
Everything is working except sms...
ok I tried download new UL2 modem I follwed dirrections first off NO ltw (maybe not in my area) but 4g icon only 2nd my download speed like .15mb
then I reflashed the UL4 modem one comes with now I get decent speeds but seems cut off a lot.. this isn't huge issue as I use wifi at home but when im out and about (which havn't tested yet) im not sure.
now I did follow UL2 let modem direction wondering if changed setting RAT setting shouldn't have... if u reflash modem to rat settings go back? when flashing modems back forth I read you delete Dcache and cache which I did but am I missing something? something else do after or something... thanks
when downloading with just network it cuts out stops in middle of download ... i dunno what deal is anyone else got info on this? if I reflash a modem back do i need fix permsions?
well i flashed orginal modem working alright guess thought icerom have better donwload speeds but wow its slick and clean looking I really like it :O) yaaaa
I had no issues with the ucld2 radio while I briefly tried it. I'm going to be honest a say u don't seem experienced enough to be messing with the RAT settings of the radio, and should leave the default settings alone. On first boot after install dial *#2263# and set to auto, then menu > end, and reboot.
Make sure your apn is set correctly, especially if you are with rogers. Using the ltemobile.apn with the skyrocket even in an area without late results in data drop outs, as the phone searches for late signal. Same goes for AT&T. Make sure you are using 3g apn values, which will work fine for 4g.
I'm having the same problem. I tried Sky ICS 4.2a, then 4.2a-8, then 4.2d, and now 4.2a-9.
I've been using UCLD2 on these and had no problems, until today when I installed 4.2a-9 and all of a sudden I can't stay on LTE more than a couple minutes. It drops down to HSPA and drops the data entirely. I've NEVER had this problem, and I've tried every radio there is. I flashed back to UCLC4 and I'm still having the problem.
I'm searching the forums for a fix right now. I might just wipe again and start over with the base/modem.
EDIT: I've tried changing the RAT on both new radios by pulling the SIM, setting LTE/ALL, then Automatic. No change.
After months of having this reoccurring issue myself, I FINALLY figured out a solution. It had gotten so bad on mine that wiping the rom won't matter... the only solution was to wait for several minutes/hours until it returned or switch to a Sense-based or a GB rom. This fix should appeal to those who had to return to older roms due this issue driving them insane!
Let's clear up a few things first.. to those having this issue and being able to restore data by going into airplane mode might wanna invest in a new sim card. Best to go into a retail location and pick one out yourself. The newest ones (model number TM9177 or higher) work the best and have the fewest data drop offs. That should fix a lot of users intermittent data issues from returning.
If you still have data issues and already have a newer model sim card (TM9177 or higher) OR have data issues that don't get fixed after a reboot, switching into airplane mode, wiping, normally have to wait a long time for it to return on its own, etc.... then this part will fix it. :highfive:
Go to home, menu, settings, wireless & networks, more, mobile networks, access point names, menu, and FINALLY add a new apn. Chose whatever for name of apn (maybe tmobile alternate, tmobile 2, or whatever), the next line, the actual apn, with be "wap.voicestream.com" (no quotes, duh). Next add this line to MMSC... "http://mms.msg.eng.t-mobile.com/mms/wapenc". Everything else should be left as is. Now hit menu, save apn. This new apn seems to work with all features I've tried... text messaging, full data access, same speed as default epc.tmobile.com apn, tethering, etc. Haven't tried MMS but the settings for that line is there in our alternate apn we just made. Please post results on that if anyone still uses that feature So... that's it. The old apn works nicely and you say GO TO HELL! to the annoying data icon flashing on and off forever!
Be sure to post your results/experiences to confirm but it seems to be gone on 4 other MT4GS CM9/10 users besides my own. I REALLY HOPE y'all are as happy with this fix as much my family, friends, co workers, and I are! Do forget to use the thanks button
Also... you can try "internet.voicestream.com" for an additional apn. I'm not sure if MMS will work on that one even with the MMCS set as "http://mms.msg.eng.t-mobile.com/mms/wapenc" but it's work a try. If anyone wants to check it out is welcome to. Again... post your results. I'm not sure how long tmobile will leave these old apns active but I bet it's longer than anyone will be still using this model lol! Enjoy!
I've been one of the lucky ones not to have had this problem but if this fixes the issue of those that have been, this is one NIIIICE CATCH! GOOD WORK, sino8r!!
I'm very anxious to hear how this works out for everyone!
Intermittent Data 3G 4G Loss Disconnect
Wow, Thanks. I've been fighting with this all day.
I've been running SilverL CM 10.1 for a couple of weeks and today suddenly lost my T-Mobile data connection.
I tried many solutions (I wish I'd found this thread sooner). Wiping Cache, Fix Permissions, Reflashed, different Kernals, different loads. Going back to Gingerbread worked, but I lost the data when I went back to ICS/JB.
There was even another thread that was close with deleting all APNs and creating a new one, but the settings still weren't there.
This took care of it right away.
THANKS !!!!

Tested it with 2 diffrent JB roms fixed data problem in about 10 seconds from selectign new APN. Data speeds are back to normal! Will update if anything changes.
After several days even weeks of no issue then suddenly I get data issues again so I go back to mobile networks to find the second APN I created to be deleted... Anyone experience this?

thanks for the info! i ran across this thread while searching for a new ROM for my mytouch 4g slide, hoping it would fix the issue. once I arrived to the access point names, i noticed that the apn selected was for LTE. I switched to the regular one and now it works great. thanks!
I had this issue while on cm9 releases but it had gone away after I began using unofficial 10.1. Sort of. In certain areas- and I assume with certain towers - my data wouldn't work with some apps (ie., Facebook, Google maps) even though the data icon would show "H" or "3g" locked on and blue consistently. Sure enough, this fixed it right up.
Also, although my phone shows the option for the Tmobile lte APN in the settings, it was not selected by default. Thanks for this!

Okay, so I've been searching the net for days and to no avail. I installed the new Cyanogenmod on my Nexus 5 and found it, well, awful. It kept hanging, restarting etc. Now when I tried to revert back to stock, I downloaded the image file from developers/google/com/android/nexus/images, and there's no 4g. No mobile data whatsoever. I can call, the Wi-Fi is working, but no mobile data. I've tried factory resetting, installing a different radio zip etc. When I install Cyanogenmod again, the 4g works again, but after going back to stock nothing again. Any help?
Wow, this is stupid, but after trying everything, including running every new stock rom, I tried installing the 4.4 (KRT16M) AND IT FINALLY WORKED. I'm gonna leave this up for anyone in the same situation as me.
Well, would you guess, the problem's back, but from a different angle. After installing 4.4.0, and letting the device upgrade itself to 4.4.4, the data worked perfectly. Now I tried to install the android L developer preview and again no data connection.
Does anyone have any idea if it could be a regional issue or something? I tried flashing older radio zip files but to no avail, now back to 4.4.0 .
Try setting a new APN with your carrier settings.
I lost connection all together last Saturday. I flashed CM 11,Friday and all was well. Received a call Saturday, it rang once then lost connection. Had to reboot four times to regain service and that was short lived. After any call incoming or outgoing, I lose service. All APNs are present. WiFi works. SIM alert when SIM is removed. SIM works fine in my N4. Did a complete tear down and it's not hardware related.

Sim works fine in my N4 also
If you loose signal might be a radio problem, still if you have signal but no connectivity try with the new APN, android (CM, stock unless carrier stock) had errors in the APN list for my carrier and I had to manually add it each time I used a new rom for several years.

i think speedtest, advanced download manager, the first time it happend, i had just flashed slimkat 5.10, i set everything up, and i used the LTE quick tile to turn off LTE, my hole signal dissopeared and my phone crashed, i had to restore to stock to get it back. now it does as i discribed erlier.
man, i just got off the phone with a robot from tmobile customer service. she had me turn the phone off and pull the sim card, she told me she "refreshed" my service on her end and the problem was "gone". ya, its not.
I'm running EuphoriaOS (Euphoria-OS-1.1-ls980-OFFICIAL-20150622), which is a custom Lollipop rom. It's been working ok so far up until a few days ago, when my data connection just suddenly broke. Granted, the 4G/LTE wasn't functional before either, but I use wifi a lot and 3G is tolerable. But now I get nothing. Texting and calling are fine, though. I've had to mess with flashing APNs separately to get any cellular functionality before, but reflashing that to fix this new issue hasn't worked. I've googled how to fix this for hours, and I've tried pretty much every "fix" out on the internets. Still... nothing works. When I try to add APNs through the phone settings menu, it says "APN settings are not available for this user." I can tap the 3-dot icon and add the APNs and then tap Save, but the new APNs (or any existing APNs in system\etc\apns-conf.xml) are visible in the APNs settings menu. I tried resetting to default. I tried wiping cache. Tried reflashing the rom. You name it, I tried it. I guess the only thing left is to flash a stock rom and update prl and whatnot. That's a ton of hassle, and I don't even know if that'll work. I could only find stock kitkat roms too... would fixing data on a KK stock rom even do anything?
Help! Thanks in advance!
