I've just upgraded my SIM only contact to another SIM only contact. I'm being sent a new SIM card but can I continue to use my existing SIM? If I have to use the new SIM card then will my existing number be usable on the new SIM card?

An upgrade order would normally be processed within 24-hours,
Your existing iD SIM should continue to work - a new (inactive) iD SIM might be dispatched, in case your existing SIM doesn’t fit your upgrade (iD seem to assume you’ll always be upgrading your phone).
+22Can you confirm if this was an upgrade or a new connection? A new connection would give you a new SIM card with a new number.
+22If it’s an upgrade then your number should stay the same. Not sure why you have been sent a new SIM card though. Please double check the documents to make sure you haven’t taken a new connection with a new number.
Hi
Thank you for getting in touch.
With an upgrade, a new SIM would not usually be sent as this is just a change on our system and should not impact your SIM or number.
Can you please double check your order confirmation that is an upgrade to your current plan and not a new sale?
Thanks,
Nat
