My husband is a truck driver and has a Bell Samsung Galaxy Discover. Currently, he uses two phones - one for in Canada (Bell phone) and a generic ATT phone.
I went and unlocked the Discover phone and tested it to make sure it was unlocked. I put my Telus sim card in it and it works fine. When my husband puts his ATT sim into the Samsung Galaxy Discover, he is getting invalid sim. I thought these phones were good to work with ATT when unlocked. It works fine with his Bell sim card.
Any ideas or is it just that it isn't compatible with ATT?
