Hi, I bough a prepaid Swisscom SIM card and when installing it in an old iPhone 6 I get a message ‘SIM not supported’. it says the iPhone is from a carrier that is not supported under the activation policy. Can you help?
I also don't know what's the problem but usually when sim card is used with ip for some time then when i insert that sim card to another ip it doesn't work. Is it because of the settings as you said or my phone has a problem
