Network locked on my iphone 11 pro

A SIM-locked phone can only be activated with one specific carrier. You must contact that carrier and ask them about their unlocking policy. Here is more information→How to unlock your iPhone for use with a different carrier - Apple Support

There’s no point in requesting in this user-to-user forum, as no one here has access to any information about your phone. And there’s no point in asking Apple, as they cannot unlock your phone either. ONLY the carrier it is locked to can unlock it.

While you seem to have already solved your tech support issue, you may find that the answer provided by Mr. Finch above will be appropriate.

There is probably no way you can use that phone. The phone was financed through EasyPay, and was never fully paid off. If you bought this phone used the seller still owes money to EasyPay.
