invalid sim and no sim message with iphone 4s?
i have recently been getting the "no sim" or "invalid sim" message on my iphone 4s. iv tried all that i know from removeing the card and putting it back in, rebooting phone seems to work 4/10 of the time and will get the same message after like a half hour. i took my iphone to the bell store and bought a new sim card and im still getting this message so i do not think its the sim card itself??? any ideas on how to fix this? it is very annoying 😟
iPhone 4S, iOS 6.1.4
