Hi guys,
I've tried searching but have not found the answer. I successfully rooted and loaded AOKP, as well as CM10 and one other ROM. On all of them, I can make calls and use wi-fi, but can't get mobile data. The signal bar shows "3G" and "H+" at times, but never turns blue when wi-fi is off. I've checked http://support.t-mobile.com/docs/DOC-1976 (t-mobile site) which includes instructions on APN settings for data and picture mail, but that didn't seem to solve the problem. I've also tried turning Airplane Mode on and off, and I've done a factory reset and cleared Dalvik cache for each ROM. The SIM card is about 4 years old, if that matters.
Thanks a lot for the help!
Sounds like the sim card my sim card is less than a year old and randomly my phone doesn't have network and a message comes up and says to clean my simcard because its dirty or corrupt. So I turn my phone off take out the sim wipe it on my pants lol and insert it back in and its fine after that. I would get a new sim and try it out or use a friends sim and see if it works correctly if not then it sounds like the sim port on the phone itself.

Hi all, i'm currently on MIUI 1.8.26 but this started with 1.8.12 but i don't think the rom is the problem.
So in short, Tmobile gave me a new SIM for idk what reason. My phone just signal just stopped working so i had to get a new one, (there fault) now that i have the new one, everytime i turn on wifi or just after a short period of time i lose data and it doesnt come back. I have to pull battery and take out SIM card for 10 secs for it to return... any ideas?
You mean when you turn wifi on your 4g/2g icon disappears from the status bar?
yes that's what i mean. It just shows the bars. but my browser doesnt work or i cant send mms. basically no data...
Are you actually connected to a wifi network?
No i turn off the wifi to check if i have data but i dont. but yes i am connected to a network when it is on. But still this never used to happen until i got that new sim card...
Yea not sure. If it started when they replaced your sim card then I'd probably just go have them replace it again. In the mean time have you tried a hard reset to fix the connection issue? It might work and save you from having to take out the sim card each time. To hard reset you hold volume up + power for several seconds until the phone shuts off and reboots.
Finally someone has some answers I have been trying to find out what a hard reset is for a while and how to do it.
I AM having the same issue but instead ofwheni shut offwifi it happens when I shut off the phone. I installed EB 1.08 and it is giving me problems. Later I will try a hard reboot.
Hi,
I'm a quite newbie in the htc android tweaking world, so please be a bit understanding.
I know that there was a thread like this on this forum, but I couldn't find now. I'm sorry for that. If anyone can point me that thread, I will paste my post there, and ask for closing this one. I know that it is annoying when users create multiple threads with the same topic.
Well, I bought my phone on an auction as British T-mobile branded, but sim lock has been removed. I used it in Poland without problem, but when I got to Belgium I started to have major issues with Base network.
Since the phone had simlock removed not legal way, I S-offed with revolutionary (my HBOOT since then is in version 6.something - is this good or bad?), then rooted, finally debranded by installing original, signed Europe ROM, although I tried several roms before.
I used ClockworkMod as my recovery tool, but recently I read that it is deprecated, so I flashed it with 4ext recovery. I'm happier with the new tool.
Anyway, My problem is that before I could not use any simcard from BASE, the phone refused to connect saying that sim card refuses the connection.
It was with any andy version, so I actually applied the 1.47.401.4 update that everyone hates, and I didn't see any difference.
Then, very recently I found a post about a new radio version 20.48.300822U_3822.09.08.20_M. I applied it, and also copied the RIL files. It got better, I finally can connect. I had to drink for that Two months of fighting...
But every time the signal drops badly, the phone disconnects from the network and refuses to connect again saying that sim card doesn't allow connecting this network, and shows notification that BASE network is unavailable. Despite that, GPRS data connection is active, and I can connect to internet. Isn't that odd?
Then I need to reboot to 4EXT, and whipe Cache and Dalvik cache. It usually happens once per day - at my work, where I have quite network signal. Supprisingly after cache whiping, the phone can connect, and it seems that signal strength gets better...
I'm glad that after clearing the cache everything works, but I would be even more happy if I wouldn't have to do it... Does anyone know the problem? Has experienced something like this? Has a solution?
Should I use the new 2.3.5 based official rom? Can I transfer data somehow, so when I flash the phone, I still have the data that was there before flashing?
Hey, i'm on Mobile Vikings wich uses the BASE network but i never had anything like this before, could it be a kernel issue?

In short:
My phone was original British T-Mobile branded. I s-off my phone, rooted, changed roms but I still had no connectivity to Base in Belgium. I tried experimental roms, original roms, branded roms, radios... but nothing changed. After switching to original HTC European rom, applying 1.47.401.4 update and flashing the newest radio, I have connectivity, but still in bad signal range, my phone would disconnect from Base, and display me a message that the sim card doesn't allow connecting to this network. Then I need to boot to 4EXT, clear cache and dalvik cache, and after reboot everything works fine for a day or two...
Update:
Today clearing cache didn't work... After searching for network, I select BASE and I get a message saying that sim card refuses to connect to this network. Clearing cache, going to flight mode, just restarting the phone - nothing works... What else can I do?
There is one another thing I find weird - in mobile networks settings, every time I select network mode WCMDA or GSM, it always goes back to "WCMDA/GSM Auto" and I can't chage that.
Buy proximus or mobistar. I reccomend mobistar, best signal in BE

Yeah, but they have expensive internet. If I had just for calls, I would not buy belgian sim card at all, but use my polish number. Call prices are not that much different in roaming...
By the way, I switched to the new, 2.3.5 OTA update based rom by proxuser, but still no luck.
After many hours of stuggling, searching for answers - I found another thing that helps me: sim card needs to have a pin lock enabled. That's crazy, but works - When I loose my connectivity (described above), I reboot the phone, enter pin and everything works fine... sometimes I need to switch to a drifferent pin locked card first...
It would be better if I had not to do it everytime I loose range... So I see that sim settings are also somehow cached and switching to other sim card that has pin enabled cleans that cache. is there a way to clean that cache without having to switch sim cards?
Where can I find this cache? is it a file that could be deleted (or cleared)? formatting /cache partition, as well as clearing Dalvik cache didn't work, so I guess it is not there...
Because the procedure to renew the connection looks now like this:
1. turn off the phone
2. enter sim card that you know that will connect
2. boot into recovery, wipe cache and dalvik cache, reboot
3. provide pin and wait until it connects to a network
4. power off, switch card to the belgian one, power on
5. wait until it connects by it self. if it doesn't start from point 1...
it usually catches after 1 or second time...
agh, ity only worked for some time... now nothing works... I can not even connect to BASE using any other sim cards that are in roaming... I'm able to connect with other mobile phones, but not this... But it connects to Mobistar and Proximus without problems... I'm suspecting some kind of a defect that appears only with this network. But since I don't have warranty to that phone, I can't send it to the service...
I will try to return to stock rom again...
Now I'm using the phone with my Polish sim card in roaming, but actually I can't use internet then, and all I wanted it for was mobile networking... For a phone just for calling and sending messages any other phone that costs half of the price would be ok...
Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.
I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.

I did try that. Nothing seems to be working.
Greetings folks,
Some weeks ago I flashed the Rom back to stock, and the phone is working absolutely fine, but when I turn on the data traffic, the 3g/hsdpa icon doesn't show up, despite I've got the right apn settings. I also tried my SIM to another device with the same apn configuration and still couldn't get the certain icon, although the other device worked fine with another SIM. I think it's the card (data traffic not enabled in the SIM), but I'm not 100% sure. So, is it the phone or the SIM card? And what should I do to solve it?
I just tried another SIM in my phone and data traffic worked fine, so it's SIM's fault. What can I do so I can fix the issue?
Problem solved.
As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!
Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.
I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.
