Hi
I've just got my new phone and transferred SIM from oldphone to new one, Ive just realised in the box there is another SIM saying SIM swap as O2 are encouraging to upgrade all Sims. Will anything bad happen to my phone if I keep my old SIM in. It seems to be working fine now

Hi @Simswap1 

Nothing bad will happen to your phone if you keep the old sim in other than you will only get 4G. If you have a 5G phone and are in a 5G area,then you need to do a sim swap Guide: Sim Swap: a mini guide 2017 update from your old sim
