Important Information

IMPORTANT: Be cautious of providers advertising "Unlimited Data" without clearly disclosing their limits. Vague wording about slowdowns "beyond their control" that "normalize the next day" usually points to a hidden daily cap — always check directly or review their website for details. Our eSIM includes a clear 3GB daily high-speed data limit. Once reached, speeds reduce to 128kbps for the rest of the day. Your high-speed data refreshes every 24 hours from activation, giving you a fresh 3GB each day for the duration of your prepaid plan.

Linda S.

Worked well no problems

SIM card was great this is the second time Iv used one overseas worked well no problems at all I’ll be using Sim Corner again

Kenneth S.

Not worth the money

The data capacity depleted very quickly. . . . . I believe some sort of scamming took place. . . I will never use this service again.

Anne H.

Excellent

I've used these SIMS in various parts of Asia and Europe, and found them to be easy to use and reliable. It's so much more convenient to purchase one before I leave home rather than waste time and energy looking for one at my destination.

Wendy C.

Very good, worked as expected and hoped for.

Great, worked in all 3 countries I visited - Nepal, India and Sri Lanka. It did take 4 hours to activate in Sri Lanka after turning on, but was very quick in India and Nepal.
