What is a SIM Lock on an iPhone?
A SIM lock (also called a carrier lock or network lock) is a software restriction placed on a device by a mobile carrier. When an iPhone is SIM locked, it can only be used with SIM cards from that specific carrier — inserting a SIM from another network will display a "SIM Not Supported" error.
Carriers apply SIM locks to devices sold on contract or instalment plans to ensure customers fulfil their payment obligations. Once the contract is paid off, you can request the carrier to remove the lock, making the phone "factory unlocked."
Knowing the lock status is critical when buying a used iPhone. A locked device may not work with your carrier, and unlocking it after purchase can be costly or even impossible in some cases.

Why Check SIM Lock Before Buying?
Avoid Network Incompatibility
A locked phone won't accept your SIM. Check first to avoid buying a device you can't use on your carrier.
Travel Freely
Unlocked iPhones accept local SIM cards abroad, saving you from expensive roaming charges.
Higher Resale Value
Unlocked devices sell for significantly more on the second-hand market than carrier-locked ones.
Verify Seller Claims
Sellers often claim devices are unlocked when they aren't. Our IMEI check gives you the definitive answer.
Plan Your Unlock
If a device is locked, knowing which carrier holds the lock helps you request an official unlock.
Protect Your Investment
Buying a locked device unknowingly can cost hundreds in unlock fees or render the phone unusable.
