Where are you located?
Did anything change on your phone before the problem arose?
Can you try your SIM in another unlocked phone to see how it works there?
Maybe your SIM has developed a fault and you need to try a replacement?
Do you mean that you have no connection to the 48 network at all - i.e. no signal bars?
What happens if you do a manual search for networks?
Can you see and connect to 48?
If not then what happens?
Any error messages?
If you need to contact 48 support about this then see the links in my signature below.
