I just ordered an S23 upgrade from T-mobile because I am going to the UK for a year and want to use dual SIMS. Can I use two eSIMs at the same time or does one need to be a card in order to have both active at the same time? T-mobile only sent me a QR code for an eSIM, can I use the card from by S20 FE instead? Or can I take it to a store to get a SIM card? I'd like to be able to set up the UK carrier before I leave to make sure it works ok, and obviously I can only do that as an eSIM. (I know I can get a physical SIM when I get there.)
Thanks in advance
