Some old type sim's arn't accepted in newer phones, I have an older BTCellnet sim with free best friend that doesn't work in newer handset. I keep using it in the old handset because I can....! Regards.

it was a water damaged 3310 which is showing CONTACT SERVICE. I had thorughly clean it by alcohol. Then Full flash it through Ufs3. The set runs for one day after that it switchesON showing network and operator logo but after 30-35sec it switches off and switches on automatically then only show the battery bar and then shows "sim card not accepted". Is the cobba is faulty if yes how to check it otherwise any other solution please.
