Sim swap??

[4K]

i bought the new phone with o2 line. i would like to have the same number which is also o2.

How can I swap the same number?

It's referred to as migration

If you are already with O2 you can just use the old sim card

If wanting to use the new sim you need to do a sim swap

@4K If you're not comfortable doing a sim swap yourself, call into an O2 store, if you have one nearby, and they'll do it for you. Be sure to bring photo ID if you choose to do that.
