Sometimes you can't help it, you need a phone today, and need to go into a store for your phone company. No, buying a phone from Walmart or Best buy and waiting for a sim or doing some eSim thing won't work, you just need to get into a branch today. If an MVNO with no branches works for you, great, but some people need to be able to go into a branch of their cell phone provider/bank/utility.
