Howardforum Members,

The iPhone 5, 5S, 5C is an older iPhone but there are still many people who want to get the network unlocked. If you are experiencing the message "Sim not supported" that means it is still network locked, and you need to get it factory unlocked in order to use it with another network. The customer here has a Bell iPhone 5S and want to use it on other carriers. Watch this video example on how to unlock iPhone 5/5S/5C
