How do I unlock an iPhone SIM or get carrier unlock approval?
Answer
Carrier unlocks are approved by the original carrier after eligibility rules are met (usually paid-off device and active account history). Request the unlock from that carrier, then insert the new SIM or install the new eSIM and restart the iPhone.
Before you start: stop right away if…
- Third-party unlock services are frequently scams and can put your account at risk.
- Too many incorrect SIM PIN attempts can lock the SIM until you enter the PUK from the carrier.
Follow these steps
Separate SIM PIN from carrier lock
If the phone asks for a SIM PIN, enter the PIN from the SIM tray paperwork or carrier account. If you see SIM Locked or the new carrier never gets service after the PIN works, continue with carrier unlock steps.
You should see: You know whether you need a PIN, a carrier unlock, or both.
Request unlock from the original carrier
Sign in to the original carrier's official app or site, or contact its unlock support, and request a device unlock with the IMEI from Settings, General, About. Ask about eligibility and processing time.
You should see: The carrier confirms the unlock request or explains what still blocks eligibility.
Finish unlock on the iPhone
After the carrier says the unlock is complete, remove the old SIM if present, insert the new SIM or install the new eSIM, connect to Wi-Fi if prompted, and restart the iPhone.
You should see: The new carrier shows signal and Cellular settings accept the new plan.
Avoid unofficial unlock sellers
Ignore websites or callers that promise paid IMEI unlocks outside the carrier. If the carrier denies eligibility, resolve the account reason they give instead.
You should see: You stay on the official carrier unlock path.

Extra tips
What to look for: SIM Locked, Enter SIM PIN, No Service with another carrier's SIM, and carrier unlock confirmation by email or account message.
Before you change anything: Know which carrier originally sold or financed the iPhone. Confirm the device payment is paid off if required. Do not pay third-party unlock websites.
