Hi ​@Kir,

Thank you so much for reaching out to us with your question.

With regards to upgrading and changing your number, these are two separate processes.

To keep your existing iD Mobile account, you would first need to upgrade your contract. If you then wish to change your mobile number, this can be requested separately after the upgrade has been completed. Number changes are chargeable at £25, and any replacement number allocated will be selected at random and cannot be chosen or customised.

Please note that upgrades can only be completed on the original iD Mobile account and number. Changing your number does not affect the upgrade itself, as it is processed separately. 

Regards, 

Zubair
