I upgraded my mobile today from an iphone 5 to an iphone 8. I have put the sim card in from my iphone 5 and it keeps saying SOS only or no SIM.
I dont have the option in the Settings under "Mobile" to access the menu to make any changes, it just says "No SIM"
I have taken the sim card out and put it back in again a couple of times, turned the phone off and on and the updates are current. Can anyone please help me fugure out what is wrong?
Hmm I suspect the sim has been deactivated if it wont work in your 5. Have a word with support on the live chat below to see if that is the case.
