Is there an easy east to see if my 3 mobile XZ is locked to the network without using another SIM? I know the bootloader is locked.
Thanks

Check if IMEI is correct. Use #*06* on the dial pad and see if it matches the phones original IMEI

Support for Tesco mobile

Hello, does anyone know if I flash a custom rom, or a specific rom, will it support Tesco mobile? I have rooted the phone, and it is factory unlocked, but for some reason, the phone will not register on Tesco Mobile. It wouldn't before I rooted it either. Options for Vodafone, Orange, 3, O2, appear, but that's it. Giff Gaff even worked. Any ideas please would be very helpful.

Have you tried to manually enter them in and save it, they normally come through if you restore to default.

Can you explain what you mean by manually entering, and how I do this please?

I've got the settings sorted, however still shows no mobile network when I try dialing a number. I've even got four signal bars so don't understand what's wrong!

Carrier sim lock

Ha there.
Is it possible to remove Carrier sim lock on the phone by any mod, rom or app??

No, contact your carrier to request a sim unlock. Most carriers will do this for free, or charge a little amount after your contract is done. If your contact still runs, you will probably need to pay extra.

[Q] Phone Locked Update to 8.1

Is it safe to install the developer preview eventhough the.phone is in a contract on a certain telco? Does.it. Not affect the signal functionality?
Or it is only applicable to open line phones??

Click to expand...
Click to collapse
Since you don't flash the Radio ROM, but only the OS itself, it should work.
Ah ok.. But is there a way that the phone can be sim unlocked?
