You need to do a sim swap from your OLD sim. All info here

I can’t do that as I don’t have the old sim to even do it with I’ve lost the old sim and can’t find it but they gave me a blank one so what can I do

[Liv2]

But I can’t remember the old number as I don’t have the old SIM card and I can’t make calls on the blank one at all any other suggestions
