I have a back to back trips to Bali and Japan. I want to use eSIMs (not used before). Looking at Ubiqi (that gets good reps in both places), it's cheaper for me to buy two separate Indonesia and Japan plans (short one-off each), rather than the "Best Asia" plan that covers both countries.

My questions are:

1. Can I just purchase both before I set off? If so, will my phone automatically connect to the correct one in the correct country?

2. Instead, should I purchase Bali now, and then Japan when heading off?

3. Although these are two separate "plans", is it still just one eSIM?

thanks in advance,
