I bought a used iPhone 5 that was locked to Bell network (Canada). For some reason, only Bell iPhones can't be unlocked through those IMEI services. Bell does unlock it for $75, but you have to have been a customer (which I am not), and completed your contract or something. The only solution I've found are r-sim cards that you can buy for ~$30. Has anybody here actually tried them out??
