Q: how to recover my iphone 4 when a message says "The sim card that you currently installed in this iphone is from a carrier that is not supported under the activation policy that is currently assigned by the server..." Im from Philippines.

Hello there khraye,

This message appears when the phone is locked to a specific carrier. You will need to contact the carrier the phone is locked to:

How to unlock your iPhone for use with another carrier

Unlock your iPhone

First, your carrier will need to process your unlock request. Then you'll back up, erase, and restore your iPhone to unlock it.

Start the process:

1. See if your carrier offers unlocking. Only your carrier can unlock your iPhone.
2. Contact your carrier and request an unlock. You might need to meet requirements to qualify for unlocking. After you submit the request to your carrier, it might take a few days to complete. Contact your carrier for the status of your unlock request.
3. After your carrier confirms that your iPhone unlock has been processed, go to the next section.

 

If you have a SIM card from a carrier other than your current carrier, follow these steps:

1. Remove your SIM card and insert the new SIM card.
2. Complete the setup process.

 

If you don't have another SIM card you can use, follow these steps to complete the process:

 

1. Back up your iPhone.
2. When you have a backup, erase your iPhone.
3. Restore your iPhone from the backup you just made.

Thank you for using Apple Support Communities.

All the best,
