Very convenient and quick eSIM registration at a reasonable price. A local SIM card with a similar plan would have cost me about the same. Overall, I highly recommend it! :)

I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.

The sim card is easy to install (in-app). The internet is fast enough. For me the 9gb plan was enough for both: work and personal stuff.

It's incredibly convenient! You install it at home, fly to your destination—in our case, Phu Quoc—and you've got internet right away! The instructions for installing and activating the esim are clear. We traveled all over the island, and we had connection everywhere. 5 GB per day was enough for three phones (two via a hotspot). I highly recommend it!

E-SIM is very convenient these days; I installed it at home. Upon arrival in another country, you're already connected while sitting on the plane. The SIM card worked reliably. We went to Phu Quoc, then Nha Trang.

• Super easy setup: Simply scan a QR code to complete the setup; no need to remove or insert the SIM card. • Uninterrupted service for your original number: You can retain your original number to receive SMS messages (crucial for receiving bank verification codes!) while using international data. • Buy and use instantly: If you run out of data, you can easily add more with a few taps on your phone; no need to search for physical stores. • Stable network speed: Navigation, sending social media updates, and watching videos were all very smooth during my trip abroad; I almost never encountered any network outages.
