It shouldn't create a problem at all.</P> Sun, 15 Nov 2020 08:56:24 GMT https://community.o2.co.uk/t5/Apple/Dual-Sim-on-iPhone12Pro/m-p/1408952#M166408 Cleoriff 2020-11-15T08:56:24Z https://community.o2.co.uk/t5/Apple/Dual-Sim-on-iPhone12Pro/m-p/1409200#M166416 The only thing to be aware of is at the moment you cannot use 5G with dual sim (until Apple release a software upgrade), so if you have both SIMs on you will be limited to 4G only Mon, 16 Nov 2020 10:44:50 GMT https://community.o2.co.uk/t5/Apple/Dual-Sim-on-iPhone12Pro/m-p/1409200#M166416 PhoneChanger 2020-11-16T10:44:50Z
