I have just recently got a s21 and am having a annoyance where everytime my phone restarts it asks me what sim to use. I am currently using a eSim and was wondering if I can disable the other sims and set it as default?
I don't think you'd be able to disable the sim without there being one in either slot. Could you try putting an old Sim in (a physical Sim) and then if this warning appears it might give you the option to set to e-sim default?
