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.
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.
Hi there, just wondering if anyone can help with a small problem I'm having after flashing a new ROM - {ROM}[T][STOCK][JB 4.3][UB&LB][9.2.A.0.295] Official Firmware - Rooted&Deodexed 18/02, by DaRk-L0rD. My problem is that when I first turn on my XperiaT, I usually have no service on my phone - i.e- I cant make calls at all. The phone works fine for everything else, but I have to manually go into Settings-More-Mobile Networks and after a few seconds the phone picks up the signal and the bars appear. If I don't do this it will just sit there for hours not getting anything! I've tried entering the Phone Information menu through *#*#4636#*#*, and setting the preferred method to WCDMA, and I've made sure that in the Mobile Networks settings that is also the preferred method, however it seems that if I reboot the phone, or the battery dies and I switch it on, it randomly forgets these settings and I get nothing. If I try to enter the Settings-About Phone-Status screen when I've no signal then I get force closed, but when I have signal it opens no problem and my IMEI is there and is correct. Also, sometimes the little red missing SIM icon appears alongside the red x on the bars, although this doesn't happen all the time.
It's a small issue because it only happens maybe 80% of the time, and it's not a big deal going into settings and reactivating things, but it's a bit of a hassle at this stage.
Previously I used "[ROM]XperimenT 3.5[T/TL][9.1.A.1.145][Locked & Unlocked][23/09/13]" by TiMiN8R without this issue so I know that the phone/sim are actually ok as it only started immediately after flashing the new ROM.
You can see from my three screenshots that I have no service for two minutes, enter the mobile networks menu, and finally after being in that menu for a few seconds up pop the bars!
If anyone can help me out I would really appreciate it.
Hi, everyone!
So, my Nexus 5 only works when I set it to use 2g network.
Explaining it more clearly: when I set 3g, everything starts to go a little crazy. The phone signal gets lost back working, sometimes it doesn't even recognize the sim card
When I try to access network settings and network operators it gets really slow and sometimes the phone crashes and reinitiates.
I've tried setting a new rom and I am running the most recent version of Cataclysm right now. I've tried changing the phone modem driver too (actually I think I have just reinstalled it) and nothing.
Interesting thing is: sometimes when I turn 4g on, the internet signal works, but when I try to make a call, the signal gets lost and it appears a "turn off airplane mode" pop up.
That's it, guys. Thanks in advance for any help you can give to me and I'm sorry for any english mistakes...not my native tongue.
This handset was absolutely fine until it updated to Nougat then it wouldnt sign onto the network. It see's the network fine, just wont ever register on it. Sometimes shows a signal bar but emergency calls only, other times a circle with a 45 degree line through it. I have tried multiple roms and all the same, I should add that Secure Boot is enabled and since it updated to 7.0 I cannot downgrade back again. I have checked the phone hasn't been blacklisted, all comes back clean.
Can anyone help? It works fine apart from this unable to connect to network, try later problem.
Thanks in advance
