I have the same issue, sim showing smarty number but not the number i transferred (which is actually working). I want the sim to show my actual number. I cannot change the sim number in any settings (samsung).
seeing the same thing, i've only just got my sim so this could be a sign i need to move elsewhere. Doesnt work on chrome, edge etc. Clearing browser doesnt work. When i can get it to a stage of asking for a code the code doesnt work. Frustrating.
