Old Number

Unfortunately UK mobile number transfers don’t happen immediately, @Ben McKenzie. 

You’ll know iD Mobile have started working on your switch when your old provider’s SIM stops working. 

Sometimes switches to iD aren’t completed until 10pm on the switching date.

Hey there @Ben McKenzie, welcome to Community!

As @andewhite has kindly advised, port’s complete between 8am-10pm on the selected date.

We hope all is sorted now, but if not, please let us know.

Thanks,

Tyler
