Unlocking phone with no number

[Dumpling22]

Hi,  could someone please help??

I am currently trying to organise my life and that involved sorting out old mobiles...  I think I am going to pass my old EE Huawei phone to my Dad but can't seem to find a phone number for it which the online form needs.  I transferred my number to my new phone that I am using now.

Thanks.

If the device had been on your contract for at least 6 months, even if that contract has now been cancelled, you can just apply using the Unlocking your device form as the Pay Monthly option and giving the mobile number that it originally came with. It will first show your new current phone on that number, if any, & ask whether that is the device you want to unlock? If not, you will then have to type in the IMEI of the old phone.

Thanks for your reply.

It asks for the phone number of the device you want to unlock and that is the number I'm struggling to find?

It's the no. you moved to your new phone. You just said so.
