Q&A for How to Unlock a SIM Card on an iPhone

You should visit your carrier and show evidence that it's you with your full name, phone number etc.

This must mean your phone is locked to your previous phone carrier. Ask the carrier to unlock it for you, or simply get a new unlocked/locked to your new carrier's phone.

If your friend’s Globe SIM card is locked and they don't have the PUK code, they will need to retrieve it. Contact Globe’s customer support by calling their hotline or visiting a Globe store, as only they can provide the PUK code. Alternatively, if your friend has an account, they can log in to the GlobeOne app or Globe’s website to view the PUK code. Sometimes the PUK code is printed on the original SIM card packaging or documents. Without the PUK code, the SIM cannot be unlocked, and Globe may need to issue a replacement SIM.

It’s probably carrier-locked or restricted. Contact the carrier to request an unlock, providing proof of purchase if requested. Be sure the SIM is compatible with your phone’s network type. For iPhones, make sure there’s no iCloud lock, and for Android, check for Google account locks. If it's recently purchased, contact the seller for help. If issues persist, consult a professional repair service.

If your phone shows Bell as the provider but the IMEI doesn’t match their records, dial *#06# to confirm the IMEI number. Check if the SIM card is from Bell, as the phone may be unlocked and using another carrier. Contact the seller to verify the phone’s original carrier or use an IMEI checker online to see if it’s flagged as lost or stolen. You can also contact the phone's manufacturer for more details. If the issue persists, seek further help from Bell or the seller.
