O2 do eSIMs now or did you get an EE eSIM?Yep, but it's the best I've got at home when inside. EE are better then O2. Will come down to do I get a signal at work on EE because I don't get a signal at all on O2 unless I wave my phone by the window.
Business and Primary. They are labels added so you can tell the Sim's apart, I assume more helpful if you have two lines on one network.
