This global 77-country eSIM is too powerful! One yard to travel through many countries, 4G/5G network speed is smooth. Free choice 1-30 daily use, 24-hour billing is super fair, free card exchange is available. The traffic details are clear, and the seamless switching of travel and business trips saves the trouble of buying cards locally. The first choice for cross-border networks is super convenient!

This was a decent simcard for use in the Seychelles, coverage was pretty good but very slow after daily limit was hit. Quite pricy for the limited amount of data, but none the less convenient.

At first, I was thinking of using something like Y!Mobile's overseas service, but I heard that it would cost quite a bit of money, so I hurriedly purchased this eSIM. I was able to purchase it quickly and used it for a day without any problems.

I was able to use it without any problems. If you proceed according to the email that you received the settings, you will be connected immediately. If you do not connect, restart or once in-flight mode and then connect again.
