What exactly do you mean by "no service"?
No connection to the 48 network at all - i.e. no signal bars - or just calls/texts/mobile data not working?
When was it working ok last?
What changed in the meantime?
Phone software update, settings changes, factory reset/restore, returned from roaming abroad, etc.?
Are there any error messages on the phone?
If you have no connection to the 48 network then what happens if you do a manual search for networks?
Can you see and connect to 48?
Can you try your SIM in your daughter's phone and her's in your's?
If you need to contact 48 support about this then see the links in my signature below.
