Part 1. What is an iPhone Carrier Lock?

A phone carrier lock, also known as a SIM lock or network lock, is a restriction placed on a mobile device by the original carrier or network provider. This lock ensures the phone can be used only with the carrier that sold it, preventing users from switching to other networks without meeting specific conditions or paying for an unlock.

2. Make sure the iPhone is paid off, not stolen, and the account is in good standing.
3. Contact the original carrier via online portal, support app, chat, or call.
4. Summit the unlock request, and provide IMEI, account details, and contact info. Don't forget to ask for a ticket number.
5. Now the carrier will process your request. You can wait for approval. It will take 1–7 days.
6. Once it's unlocked successfully, you can go to Settings → General → About to verify unlock. It should say "No SIM restrictions".

However, if your carrier refuses to unlock it, you can go back to Part 2 to pick up an iPhone unlocking services online tool. Some of such tools are free to check device status, others charge a fee for both checking and unlocking stages.
