just went to the store to buy a Vodafone prepaid sim card. There were about 60 people in line.
Point of sales are out in a lot of coffee shops. Utter chaos!
If you are a software developer it's best to take a day off or read a book (good for those who have bought a physical one). No reason to stress, isn't your project delayed by more than a day anyway?
In theory, you could have line 1 forward to line 2 when 'unreached'. Of course you'd want the second line to be different network.
It would be good to have regulation surrounding eSIM, because telcos will always find a way to make it awful. E.g. able to do 24x7, max 1hr processing time, no cost to user, able to do via self-service options.
