Hi @Phanslope,

If you take out a new plan through a third-party retailer such as Carphone Warehouse, this would typically be treated as a new iD Mobile connection, which means it would come with a new mobile number.

Unfortunately, iD Mobile doesn't support internal number transfers between iD Mobile accounts. This means we can't move your existing iD Mobile number onto a new iD Mobile plan taken out through a third-party retailer should you decide to place your order with Carphone Warehouse.

The usual ways to keep your existing iD Mobile number are:

Upgrading directly on your current iD Mobile plan.
Transferring your number to another network and then back again if required.

If you're looking at upgrade deals and have found a better offer elsewhere, we'd recommend contacting our Sales Team to discuss the options available on your existing account and see whether there's a suitable upgrade available that allows you to keep your number.

You can contact them via Live Chat here: https://www.idmobile.co.uk/live-chat

Thanks,

Anneline
