Background - I'm currently with Three, and wish to run my contract for another 8 weeks until end of contract keeping my existing number with Three. I had delivered today an O2 pay monthly sim, as I wanted to take up a good 12 month SIMO deal I saw before it ended.
I note from other responses on this forum there shouldn't be any issue with porting my Three number onto an eSim, but in the O2 store where I collected an eSim pack today, they said that I have to port my number onto the physical SIM, then sim swap to the eSim or the port won't work.
My original plan was to initiate the sim swap now, physical to eSim, make use of the data and keep the temporary number for 8 weeks, then port my Three number to the eSim. Were the O2 store correct and this won't work?
