Not possible to make calls, sms or Data-Connection - XPERIA X10 Q&A, Help & Troubleshooting

Hey,
My problem:
Yesterday I flashed a few MIUI-ROMs, now I have neither a data connection, nor can I send or receive SMS. Also, calls are not possible. However, I can log in to the mobile network.
Kernel is reflashed, tried another ROM and already restored via SEUS.
Do not go on.
Can you help me?

I had this happen to me, my gsm card went bad cause the phone got hot when i loaded a kernal that was o/c, ATT swapped my sim for free, the funny part was that after I messed with the rom, I got no "faulty sim" or any alert that it was actually bad.

[Q] Can't make calls

I have looked at all of the threads and here goes...
I can't make phone calls. When I do I get a friendly message saying, "connection cannot be made." It seems to me that there is a disconnect with my provider. The provider is Sunrise Switzerland. Thus I am suspecting that I can make a call, but because I am not officially logged into the network for calling it is not letting me make calls. I am making the assumption that if it was a ROM issue I would not get the pre-recorded message from Sunrise.
Here are the details on the phone:
It is a Sony Xperia with the latest update 2.1 baseband .54. It is a "branded" phone from Orange Switzerland, but completely unlocked. I checked on the branded by looking at the services numbers.
I then modded the phone, and the phone call problems began. I did wipe everything as per the regular instructions. I upgraded using xrecovery. The phone can connect to Sunrise, and per the services menu it states connected to Sunrise. I can use the Internet connection, thus surf, get email, etc. What I cannot do is make a phone call.
Model: X10i
Android version: 2.2.1
Kernel Version: 2.6.29
Build Number: FreeX10-beta4_zdzihu
When I originally started the device I was asked for a network code and dismissed that dialog. Anything to do with it? And if so how do I get it back?
I want to stress that I wiped the machine clean with factory reset, etc, etc...
Because I posted in the wrong forum I got one answer, and followed it.
Namely I installed the Wolfbreak's ROM for my baseband. That just made things worse. I could not even get on my network.
Interestingly I decided to fallback to my original ROM, and on that I cannot make phone calls, nor receive (due to not being on the network), or data does not work. If I restore back to the ROM that I used, namely the Free then data still works, but not calls.
Found the answer and it is bizarre...
Essentially what happened is that my installation of Xperia went correctly. The problem is that I have two sims. The way to use one sim or another was to not have the other phone on. Or at least that is how I was using it.
I phone Sunrise and I told them my phone is activated. He said, "no your other phone is on." I pointed out and he then said to activate my phone. I did as per his instructions and all went ok.
The funny thing is that this was a "bug" in their system that they patched. And the patch JUST happened to be the same day as when I upgraded my phone to the new ROM.
The tech support was nice and cracked up laughing...

HELP NEEDED!!! Cant send or recive calls!? PLEASE HELP!!!...

EDIT: Just tried a 3 sim card and it worked so I will get another T-Mobile Sim to see if the problem is a didgy sim card...strage as the sim works when I put it in a micro sim to sim adapter in another phone!?
Im in the UK, with T-Mobile and randomly cant send/recieve calls or texts
I called T-Mobile and they refreshed the network settings but I still cant call...they said it wasnt anything to do with network coverage as it was displaying i had signal, but in call settings > additional settings or call forwarding > voice call:
it says "Network or Sim error"
my sim works in another phone too so its not a dodgy sim...so it is 100% down to the phone that I cannot call or recieve calls or texts so not just call settings being messed up, problem surfaced 2 hours after flashing Foxhound 0.3 (but in those 2 hour calls/texts were working)
I have done hard reset, and facory reset, restored a backup...also flashed stock XXLF2, and also LF8 but all with no luck
My IMEI number is displayed in about phone, it is displaying full signal, and T-Mobile in the dropdown menu and im able to use my mobile data from T-Mobile so what is wrong, and how can I fix this?
Would be forever grateful to whoever can help me out...even if your not sure any ideas are welcome as my £500 phone is as good as bricked to me!
I will take it into T-Mobile to see if they will replace the handset under warranty but how do I go about making it seem it hasnt been rooted or flashed custom ROM, I know I need Triangle away but what order etc?
Thanks allot
Remove root apps .
Run Triangle Away

[Q] some SMS not received on Samsung SIII i9300

I have this problem with my Samsung S3 i9300, running on it's stock ROM, the phone functionality is fine. (not using on data network or wifi)
Means phone calls are able to be made and received without any problems.
SMS can be sent and received as well, but sometimes, messages are not received!
I've switched the SIM to another phone, and then all the messages are coming in...
I've changed the SIM to a new one but still the problem remains.
Later on, I've flashed the phone to another ROM (S4 Revolution). It was working for awhile then it's happening again.
Now, running on CyanogenMod 10.1.3, it's been fine for awhile until yesterday, with over 5.3k of SMS, certain messages aren't coming in again.
Have any one of you had this issue before? I mean SMS is like the most basic function in a phone and it's not perfect on my S3!
For the record, the application there aren't any application installed prior to that problem, and there are more than 1gb of memory available.
I guess formatting the phone or resetting it would help, or clearing all of the SMS, but would I need to do it everytime? hmmm...

lg k7 cannot send or receive messages.

so ive had my k7 for a while now, and every now and again i wouldnt be able to receive any sms messages. i could send them, but i could not receive them. they would all come flooding in at once. today, it stopped working completely. i cannot recieve any messages whatsoever. not even from myself. ive tried to use teh mmi codes, but i always get an error message. when i go to my service providers, i cannot search for any networks, yet if i hit auto connect, it says i am connected to the network. ive even tried putting the sim card into someone elses phone. it would take forever to send the messages, but it would work, and i could receive messages when my sim card was in their phone. i am at a loss and getting kind of desperate. i have even flashed the phone back to its origional state, updated the firmware, yet the issue persists. i don't know if this could affect anything, but just in case it does, i have amplify and ive disabled a lot of the t mobile wakelocks and google play wakelocks. i also have apps2sd, and linked my t mobile app and messages app to my sd card. i dont use the stock messasging app, because whenever i try and use it, it is incredibly slow at sending messages. i live a little over a block away from the nearest cell tower, so connectivity isnt an issue. is my sim card damaged or have i messed something up? any help would be greatly appriceated.

My Xperia Z2 suddenly cannot make or receive calls unless i'm on GSM

Hey Guys,
Desperate lurker here saying First of all thanks for all the guides and everything that the devs and everyone that the community has done. I've search all of google and xda but i can't seem to figure out what's wrong with me Xperia Z2 .D6503
. T mobile carrier.
Basically since yesterday, I noticed that my phone couldn't receive or make any phone calls. but data internet, wifi internet and text messaging was working fine. Whenever people call me, i would just get a voicemail notice. At the time I was on the Marshmallow Existence rom. Ive done a lot of troubleshooting since then and still I can only make a call on GSM Mode.
Here's what i've done.
Wiped data and "reset" my phone on the Existence ROM - didn't work.
Wiped everything and flash Resurrection ROM - didn't work still.
Used someone else's sim card , couldn't receive calls either.
Use my sim card on a different phone - that one worked (SO IT'S NOT THE SIM CARD'S FAULT)
Placed back my sim card in the Z2 and reset flashed the stock rom from this page https://forum.xda-developers.com/xperia-z2/general/stock-t3355768
but that didn't work either.
I've also manually put the Tmobile APN.
Basically calls only work when changing it into GSM mode. but when i put LTE/WCDMA/GSM. Calls made under LTE/WCDMA/GSM Won't even make a dialtone when I make a cal. It basically just ends after a few seconds
I'm starting to think it might be a hardware issue because no matter which ROM i put, no matter how many factory resets and data wipes i've done. I can only make calls on GSM Mode.
Does anyone have any other ideas or should I just cry and buy a new phone.?
I suggest you to flash your phone with flashtool v0.9.18.6 and flash 291 ftf and wipe all
@whatsadophone
Have you try resetting APN for your SIM card when on your device?
thanks to everyone who tried to help. I don't know what happened. but after i tried putting the sim back in the Z2 to check my signals using Signal Spy, It suddenly can use LTE again. Only problem is since i installed that stock ROM, I lost my recovery mode and can't get it back. But i wont push my luck and just keep it like it is till i buy a new phone.
