SIM CARD NOT RECOGNIZED

njazi123 — Thu, 07 Apr 2016 01:40:24 GMT

Hello.
I just bought an sony xperia m2 from a guy.
Whenever i insert my sim card it recognizes it for a few minutes until maybe an hour and then it says that there is no sim card inserted.
The xperia m2 is TELECOM BRANDED, does this have anything to do with my problem?
Thank you in advance

Hi @njazi123,

Welcome to the community.

Does this happen with other SIM cards? Are you able to test another SIM?

Hello CameronT

I have not used other sim cards but i know this one works because i use it in microsoft lumia 535 dual and works perfectly.

Thank you for replying

@njazi123

It could be that the phone its still locked to that carrier, and using other SIM cards won't work, the odd thing is that you don't get a notification requesting the unlock code.

@njazi123,

Can you test your phone in safe mode and see if the issue persists?

Can you also confirm if you cut the SIM card down to size to fit your M2?

I tried the safe mode and it still doesnt work.

Yeah the is no code nothing at all.
Some times when i enter the sim card i doesnt recognize it at all.
I have to restart the phone a few times untill it accepts the sim card and then when it accepts it after a few minutes it says there is no sim card.
I fount out that it is because of the carrier.
Many say the solution is to install an unbranded firmware.
What should i do?

I think this may be the issue. If your SIM card has been cut down, there may be minor damage to it, causing the phone to be unable to read it correctly.

Ask for a replacement SIM of the correct size from your network carrier and see if it's any better.

I am sorry for my bad english.
I bought the sim card in its size.
I wasnt cut by anything it was already cutted by the carrier i got it from.
The dimmentions are all right.

@njazi123,

Oh right. Sorry for the misunderstanding.

It's very strange that it is recognising the SIM and not cancelling it for up to an hour.

I would still recommend trying another SIM as a test but if your are on a different network to the one the phone is branded with, then @uliwooly will be correct here.

There is no official way that I can advise to flash different firmware onto your handset, I'm afraid.

i found out that i can unlock my sim carrier.
It says i have to type some codes.
I dont need to flash anything or do anything similar.
All i need is to type some codes.
I wil try that.

Can you answer me something?
If i just flash a generic unbranded rom will it damage my phone?
Everyone said that just flashing a rom wont hurm it but i am not sure.

@njazi123,

Rooting your phone or unlocking your bootloader always has the potential to cause damage to your handset which is why I am unable to officially support it.

The network that the phone is locked to may have access to the code to unlock it from their network. You will have to contact them and see what they say. Often there is a charge for unlocking a handset from a network, but it is up to them.

I do not want to root or unlock the bootloader.

It says that i can just flash without unlocking or rooting.

But anyway thank you very much for your help.

I will try to contact the carrier brand.

Thank you again

You could flash the phone with either flashtool or Xperifirm, but if the phone its locked to a carrier, it won't make a difference, you still need the code to unlock it

@njazi123

I wonder if the attempts have been used

You can check this under Service Menu

i took it to the service center and they told me that it has a problem.

Water went in the phone and thats why it wont show any services although it recognizes the sim.

It need to be fixed .

Thank you for answering me guys
