Sorry, I don't really understand as I have no previous experience in using this kind of sim at overseas.
In my case, I need a sim for (1) communication between HK and Taiwan, and (2) dining reservation/souvenirs delivery service at Taiwan. Is that "1 card 2 nos" good enough in my case?
you may buy a 2G sim card at the cheapest cost only for local use. For my case, Union card for my hubby, and local sim card for me. If for any booking like car rental, restaurant, you may leave the local tel no.
