I have a new unlicked Samsung Galaxy A3. I joined 48 and the APN automatically went to Tesco Mobile. I have deleted it everyday and manually set up the 48 APN but it keeps reverting back to Tesco Mobile after a few hours.I have also used the 48 tweaker to no avail. If I can't find a solution and I have Google this for a long time and can't find solution I am going to have to leave 48. Has anyone had a similar problem or have a solution to this problem. I have contacted 48 but they seem unable to assist.
