aloSIM

aloSIM targets travelers who want flexibility in choosing how long they stay on a single data plan. The app covers over 200 destinations, making it useful for multi-country Asian trips where you'd otherwise need separate local SIMs.

What sets aloSIM apart is the option to buy plans for just a few days of data rather than fixed monthly buckets, and most plans come with a complimentary international phone number for staying in touch.
