Lost phone

[#1]

Hi I have misslaid my phone I am sure it is at home but cannot find it.

So I had a spare sim card that I have put £10 on but with a new number.

How can I transfer my old number to new sim if I ask for a PAC code will they text it to my old number that I cannot get access to?

What should I do ?

You just need a sim swap

Hi, you can't transfer your number between accounts. You need an unactivated sim to do a sim swap on your original account at

Thanks for info I have ordered a new sim. Can I transfer the credit from the sim I paid for yesterday on a new number to my old number after I do a sim swap or is that £10 wasted.
Thanks
Jeff
