Reviews: Southeast Asia (7 countries) | 5G/4G eSIM | Day Pass/Total Package | 24H Billing | 1-30 days | QR code

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

It's tricky to use as a first-timer; I had to message the service hotline, but after that, it was all good. I think I should have just gotten a smaller GB for the week, I was just paranoid about getting lost in a country I had first visited with a huge language barrier. Hoping I can get a refund on the very first one before this 2nd sim I got. BETTER make sure to activate it in the country you're going to AFTER landing, not BEFORE departure to the target country, since it may activate the SIM that first connects to.  In short: Activate it only when you arrive at your destination. Most airports have FREE wifi!

Reviews: Asia 11 Regions & Oceania 4G/5G eSIM | TikTok & ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | 1-30 Days | QR Code

It's very easy to set up, and in case of emergency, the support team responds quickly. We stopped the data plan because it was difficult to track how much we were spending. We thought we were low, but it turned out we'd used it all. That was probably the only annoying issue. But that was with our previous SIM card; this time, we've learned how to monitor it via mobile data and set daily limits. We recommend it.

Mobile internet sometimes drops in E. The signal also disappeared in the jungles of the Phnom Kulen Nature Reserve in Siem Reap. Otherwise, everything is fine.

Used in Argentina and Brazil, along with my layover in Dubai. It worked well all around. When I had a trouble with the signal, customer service was great to help.
