Convenient and Reliable
It is great to keep in contact with home, be able to order a Grab and use maps whilst travelling and to mot rely on free wifi locations.
I did have difficulty in accessing the eSIM but once I followed the troubleshooting guide was then okay.

It is a well-organized app
It is a well-organized app. There is a good selection of bundles, and it is very easy to use. The automatic eSIM installation also works well. It is not the cheapest provider.
