[Q] T-999 Won’t Dial or Receive Calls, Shows 4 Bars - T-Mobile, Samsung Galaxy SIII

Samsung Galaxy S3 (T-999) stock, not making or receiving calls. Has been getting worse over the last 6-8 weeks. Now phone is almost unusable. Shows 4 bars of signal.
Phone says dialing, but never connects, no ringing sound. Sometimes after power cycling can make two or three calls. Often does not get data connection, though even when shows 4g cannot access data services. When others call, they go to vox mail. No ring or notification on phone. No error message.
Have tried several trouble shooting steps: Have tried different network modes. Have tired manually selecting T-Mobile. Have booted into safe mode. Have cleared the cache. Have done factory reset. Have tried different know good T-Mobile SIM card, and finally I replaced the SIM & SD Card Reader Module.
Nothing has had any effect, can anyone suggest a next step?

Flash stock firmware and factory reset. If its still happening after that theres a good chance its hardware or network issues.

In case anyone has a similar situation- flashed the factory ROM as DocHoliday77 suggested, but that still didn't fix the problem.
Had to send it off to Samsung for repair, who diagnosed a corrupted ESN and replaced the system board, (or PBA in Samsung speak).
Cost was $70, which also added a new 1 year warranty on the phone, and the customer service was excellent.

I doubt they really replaced the board. Do you have a new IMEI/ESN number ?

It actually wouldn't surprise me tbh. Its a much simpler process to swap a motherboard than to fix the IMEI/ESN problems! (I've done both, many times!)
I'd imagine, just for customer service sake, they would swap the board for a refurb and send it back. Then they can take their time getting around to fixing the original one. Then it would be come the refurb and the cycle of life continues!

Please help me - Updated Info - a Clue?

Money is tight, phone broke, bought a T-Mobile Dash off Craig's list. I am a T-Mobile Customer. Tried my sim card in it before I bought it - made a call - no problem. Got home (8 miles away) and it couldn't stay connected. Searching, searching, searching. Tried husband's sim card - same thing. D/led manual to be sure sim card was properly seated. It was. Called, texted, emailed seller. No reply. Reset phone. Same issue. Switched Sim cards back and forth, back and forth. Was able to make one call for 10 seconds and then call dropped - no service. Now I'm out my money and still have no phone. Is there anyone out there with any ideas?
Update: opened case, wiggled battery, wiggled sim card, finally got some bars. Made a call successfully. Second call - call dropped as soon as connected. Third call - Call dropped before connected. Now it still shows bars but will not make call or send text. Please Please help. Somebody, Anybody??
You might want to perform a hard reset. See the sticky at the top of the page.

What rom r u using? Have you called T - mobile and see if they had any signal reception problems in your area?, cause it can be a dead spot reception area.
Have you tried manually searching for other networks. Where I live, you can occasionally see TMo towers, but I do better to connect to a non TMo tower and be set on manual search.

Same here
I had the same problem with my Dash, and I gave up on it a year ago.
Symptoms:
Phone randomly loses signal every few minutes, gets it back a few minutes later.
Sometimes when it loses signal, it shows a SIM error or no SIM installed icon.
Battery meter varies wildly.
Actions taken:
Purchased new battery.
Tried another known good SIM (my wife's SIM - worked great in her phone).
Flashed WM 6.0 and 6.1
Result: Look at my sig
Anyone else experience this or have any ideas on how to fix? I don't even need the phone anymore, but it still stumps me and annoys me that such an expensive phone (it was expensive when I bought it 2.5 years ago) would suddenly quit working.
Thanks for the reply - at least I'm not the only one. Not that it helps, but .... did your Dash ever work when you first bought it?
Worked wonderfully for a year. I loved it. It started my addiction to smartphones and constant connectivity.

[Q] Verizon Galaxy Nexus Phone/ Data Connectivity Problems

Hi all,
Having some problems with my verizon wirelss galaxy nexus that I just received from amazon wireless. After activating and getting my number transferred from my straight talk account, I've experienced the following problems:
1) Inability to make phone calls - when doing so either nothing happens, I get some error, or I get some automated verizon message that acts like I'm not already activated. Only once has an outgoing call worked.
2) Hit or miss 4g. It works (and works well, I might add) getting speeds up to 5-6mbps two minutes for every ten minutes it doesn't work.
I have called verizon regarding the issue. They made me
1) First, shut off my phone and take my sim card out and put it back in.
2) Then tried reactivating my phone and doing stuff on their end
3) Eventually replace my sim card by going to the verizon store and getting a new one, citing the fact that sometimes amazon wireless can be known to send out bad sim cards.
I then reset my phone to factory defaults when nothing was fixed. Still the same problems persist.
Amazon is sending my a new phone which will be here next week, saying that I may have just gotten a defective phone. Could anyone here on xda help me out with my issues in the mean time? Perhaps there is something you can recommend for me to do to remedy my problems that nobody has mentioned thusfar.
Note: I live in a good verizon area. All verizon phones at my house get great service, except this one.
Thanks xda community

Radio issues

Is anyone else having radio issues with their G-pro? AT&T model here and have been having very obnoxious issues with this device. I'm familiar with the common issues of losing 3g or 4g data while in buildings and such and have always had issues with my phones while in buildings but this phone is by far the worst so far. I'm not sure if it is only a network issue or this specific phone but I can barely get it to send and receive sms inside my house. MMS, forget about it. Calls get dropped immediately when I try to make them at home, etc... Last night I was driving home and on a phone call. Over the course of the 3 hour drive I got dropped at least a dozen times. I've never had these issues with a phone. Any suggestions? Should I try to get a warranty replacement or is this normal?
Could it be your SIM card? I have only had my phone for a week and haven't had problems getting a signal. However, on my old Galaxy Note, I had a similar issue and the SIM was to blame. Have you tried turning your phone off, taking out the SIM and reinserting it to make sure it's in there fully? You could also try cleaning the contacts (the gold part on the back of the SIM).
BTW...was reading your signature and had to LOL at the part about the Nokia Lumia. I tried a Lumia and only made it a month before Android withdrawals set in--so I sold it to help pay for my OG Pro.
Haha, yeah. I liked a lot about the Windows phone but just couldn't stick with it. I'm Android through and through!!!
I'll give that a shot or maybe get into the store and get a new SIM card today. Thanks for the suggestion!
Anyone....anyone...? Bueller....Bueller...?
Swapped the SIM and didn't fix anything. Wondering if it is an issue with the phone itself.

[Q] Drops off network suggestions? -Samsung Note 2 - Wind mobile SGH 889v

So for the past year or so I've seen instances where my phone shows 5 bars and data, however calls go to my voicemail. I find out when I do something with the phone that forces it to rejoin the network.
I've got a 3rd party number that my enterphone uses, that number rings both my wife's phone and my phone at the same time. However very often only her phone rings, both of us appear to have good signals.
It seems that my phone is falling off the network but not showing this fact. If I switch to and from airplane mode it seems to regain network, or if I try to make a call it will fail the first time but work afterwards.
Any suggestion? I already installed Cyanogen about a month back hoping that this would resolve the problem, however it didn't have any impact. Same problems as before...
I'm wondering if flashing the radio would help, if so which files should I use?
I actually gave up on this phone and ordered a oneplus one, however that one arrived completely broken so now I'm stuck with the note 2 until that RMA gets approved or I get frustrated and just buy another phone.
Thanks in advance.

Samsung galaxy A50 SIM/ Mobile data problems

Hello,
Maybe you guys can help me out before I throw this phone in the dumpster.
So my phone started to overheat for no apparent reason and would shut off completely and I took it to the shop to repair,apparently the charging port was the issue, they fixed it for a reasonable price and it was all good.
Day went by with no problems and now today I cant make calls, text or use mobile data. The signal keeps going from 4 bars to 3 to 1 to the no entry sign for both sims.
I've tried swapping the sims, putting just 1 sim in i even factory reset the phone but still nothing, im not sure what else to do here. maybe my sim cards are interfering with each other or theres some obvious issue im missing?
I've tried both sim cards with another phone and both work fine, i instantly receive the configuration message from my phone provider as soon as i boot up the other phone with the sim in it but with the a50 im getting nothing.
No 4g no messages no calls nothing. Any help would be greatly appreciated. The phone is in near perfect condition bought it about 6 months ago and I dont really want to spend any more money taking it to the repair shops and i'll end up just buying another phone.
Thanks.
