I'd be interested in Thai AIS Sim2Fly roaming sim within Asia & AU if it were a little easier to top up SIM2FLY the best-value roaming SIM for everyone! They currently only setup eSIM in store and top up can be tricky outside Thailand for non-Thai residents. They also offer a "Global" 15 GB/1 year for ~ $90 USD = $ 6 per GB. It might be an interesting option for those who can't get/don't want ProjectFi/T-Mobile and want to minimize some of the local sim signup hassles. Same plan is available with a physical sim.

Are there any other non-US local sims with better roaming packages than global roaming providers?
