All,
Not sure if this belongs in here.
Can any one offer their help / opinion on this situation.
A could of weeks back I lost my previous S3 reported it lost to Tesco Mobile (sim only contract) and brought myself my current S4 LTE. This was locked to orange and I had this removed and all was working fine.
The other week went away and had no signal, not unusual for where I was as I never have any signal there so thought nothing more bout it. Got home a few days later and still no signal.
Intially though it may have been my sim as it was an old standard sim that I had cut down so ordered a replacement. Received this nad out it in the phone expecting to be up and running but no such luck.
Was on the phone to Tesco asking if the network was down and but no.
I then had asked if the phone was locked. It seems that some where along the line with on going insurance claim for the lost phone I have probably mixed them up and had the new phones IMEI blocked as well. the person on Tesco said not a problem that they can send a notice off to get the IMEI bar lifted.
5 days later and still no signal. Every thing else on the phone works, wifi (when hooked up) just no phone signal, Message on lock screen says "no signal - Tesco Mobile"
Is the IMEI still barred? Is 5 days too long for it to be lifted? I keep re- booting in the hope that it needs to be re-booted to re-set.
It has been rooted and running Cyanogen 10.1
Android version - 4.2.2
Kernel Version - 3.0.64-CM-G06b6513
I do not think that there is a problem with the root / mod as it was working fine before. Unless you can tell me other wise.
Thanks for any help advise?

You need to ask the network re the unblocking .
Are you asking a question about your SGS3 ??? I9305 or should you be in the S4 forums ???

Sorry, it's an S3 (4g model)
Called the network the other day and seems as though it has been unlocked to them but not to me. Have tried with an orange sim and same thing.
Will give them a call.
Thanks
I bought a handset a few years ago from eBay - HTC Touch Pro2 - which the owner had obviously reported lost. The IMEI was listed on the CEIR blacklist; both my Telco (T-Mobile) and the original Telco (Vodafone) said that removal of the blacklist was impossible as the bar was permanent.
Might be time to pester Tesco for a new handset if it's their fault!
Afternoon all. In need of some assistance please.
I have done the IMEI check and it says phone is unlocked.
As soon as I out in another Sim other than EE I get the Sim card isn't supported message please contact EE.
The phone is only 5 months old and has now been purchased outright using anytime upgrade . They say I still have to wait until 6 months and 1 day.
Strange thing is when phone is reset and another Sim instered it starts by showing signal bars and LTE, once activated by WiFi it won't pick up the Sim and comes up with this error.
Phone is running Android 11 beta 3 if that makes a difference.
Reaching out for help please
Hello,
So my original note 8 was N950F 256GB Dual SIM bought in 2017. It kept on working fine, until recently it started giving the problems in mentioned order
a. excessive battery drain
b. not being able to charge wired or wirelessly
c. complete blackout.
I went for a lookout of a replacement 256GB , and was able to find one on AliExpress, risky as it always is, i took my bets to order one after some correspondence from the seller who seemed legit and helpful.
Fast forward 22 days, I got the motherboard, installed in my existing body and housing, and voila it turned on and apparently seemed to be working fine. However i came to conclusion that it was originally a N950N (maybe Korea Dual SIM) motherboard which was flashed with the firmware/CSC/baseband for UAE reigon , maybe it was done by the seller knowing my location for ordering and the usage reigon. KNOX status was tipped as well, but it is not rooted as of now (maybe reverted to stock) , so all root sensitve applications (banking , netflix etc) do work as well.
The problem is, though everything works as intended. I am unable to place and receive voice calls reliably. Most of the time the outgoing call never gets placed on the network and drops after waiting for 8-10 seconds, and the incoming callers inform me that my mobile was out of reach for them to ring me.
I suspect it may have to do with the correct baseband not being compatible with local service providers.
Seeking expert help out here for the guidance , download location and the right combination of the firmware components to be used to bring the phone back to a reliable voice calling status to be used in KSA region
All help is much appreciated.

I bought s10 5g last Monday. It's model is Tmobile SM-G977T. It came with android 10 and everything was working fine until I updated it to android 11 one ui 3.1. Now network is very slow, both Wi-Fi and data. I can't receive calls or make calls. Sometimes I have to dail up a number like 5 times before it connect. I tried to downgrade back to android 10 but I get auth error odin. Please help me.
First try contacting the Carrier first, if they can't fix it then either ask for a replacement SIM.
If they can't fix it then the only other choice would be to report the issue to Samsung Members app on your device, they will be able to look into it.
Hi Everyone
I purchased a second hand s20 6 months ago and i am no longer getting any network carrier coverage.
I took my phone to local mobile repair shop and they identified that my base software was South Korean for some reason so they factory reinstalled Android 12 with UK Software. (This still does not work and they are stuck trying to solve the problem)
I'm fairly certain that this issue started when i upgraded from Android 11 to 12.
Please can anyone suggest a possible solution for my phone problem?
Things i have done so far:
1.) Factory reset phone several times including separate network resets.
2.) Tested my new replacement Virgin sim card in 2 other phones (This works)
3.) Tried several working sim cards in my s20 phone (None worked)
4.) Confirmed my phone is not barred or locked.
5.) Checked that i can see other Mobile network operators (Does not connect when i select my provider)
6.) Tested in other cities to confirm it's not a signal coverage issue.
7.) And finally, my phone has the latest Android 12 updates inc local app updates
Thank you
Just to add a further update, i have managed to get my phone working intermittently through WIFI but i still have an issue when outside my home.

Your phone can be in the blacklist as some unpaid fees in the contract of origin provider you purchased this phone. I had exactly same problems and after pay all over due bills phone went into normal.
My S20 Ultra LTE keeps detecting a ghost SIM in the second SIM slot and is making my phone lost signal. Is there a way I can convert it from dual SIM to single SIM?
