Hi ​@Callum87,

Yes, if you've upgraded directly through iD Mobile, you'll usually keep your existing mobile number, even if your new phone uses an eSIM.

However, if the upgrade was completed through a third-party retailer and you've been given a new iD Mobile number, this may have been processed as a new connection rather than an upgrade.

In that situation, iD Mobile doesn't support internal number transfers between iD Mobile accounts. If you do receive a new number and weren't expecting one, we'd recommend:

• Contacting the point of sale to discuss returning the new plan.
• Then contacting our Sales Team via Live Chat to complete the upgrade correctly on your existing account.

You can contact Sales here: https://www.idmobile.co.uk/live-chat

Hopefully it's a standard iD Mobile upgrade, in which case your current number should move across automatically.

Regards,

Gemma M
