aloSIM

aloSIM strips things down to essentials for budget-conscious travelers. You get straightforward data-only plans in India without the overhead of calling features you might not need. The referral-credit system rewards sharing the app with friends, so you can build up balance for future trips.

What sets aloSIM apart is the no-expiry unused data on certain plans, meaning if you buy more than you use, your leftover data sticks around rather than vanishing at month's end. It's straightforward, affordable, and good if you just need reliable data without extras.
