I came back from abroad yesterday, put my sim in my phone and realised I didn't have any service. No data, just emergency calls available. It is now the day after and it still hasn't been solved. I am quite sure it's nothing to do with my area as I have been travelling and moving through areas didn't change anything. Has anyone experienced anything similar? I don't think it's my phone as my other sim card worked well. I'd be very grateful for some help on this!
