I'm looking for a SIM card to use in Vietnam and Singapore next month, and was also traveling to Taiwan and Japan at the beginning of next year.
Not sure what would be the best SIM card solution to just have access to data.
Does anyone have any opinions on this?
If you are going to Singapore first then get a starhub SIM. Order on line and pick up at the airport. It allows international roaming to nearly all Asian countries for data.
Otherwise if Vietnamese first then you can buy a SIM at the airport or at convenience stores. I used vietel when I was there last year. Great 4G
