Many people tend to buy second-hand iPhones from online markets, local stores, pawn shops or through a personal transaction in order to save money! I am also one of them because I can’t afford to buy the latest iPhone model every year. Unfortunately, when you are new to the pre-owned iPhone market there is always the danger of buying a problematic iPhone. The most common problem is the SIM Lock feature. So what can you do when SIM is not supported in used iPhone?
What is the SIM Lock?
Carriers lock the iPhones onto them with the SIM Lock feature. As soon as you buy an iPhone from a Wireless Network you will be able to use only this network’s SIM cards. Sometimes things can get more tricky because there are flex policy iPhones which will get simlocked to the first SIM card’s Mobile Network that you will insert in the iPhone’s SIM Tray.
Unfortunately, the iPhone will remain SIM Locked as long as the contract is active but even when it ends, it is almost impossible or too expensive to use the Carrier’s SIM Lock Deactivation Services to unlock it. This is why many iPhone sellers sell their iPhones without unlocking them first but it will be too late when you find it out.
