Ask Lemmy

Used saily once: only works through the app, had to contact customer service so they send me a QR code to set it up. (Could not install the app because it claimed my device was not compatible)

Used airalo a lot in ~5 countries: works fully through the browser or app. No hassle to manage esims for multiple devices from a single device.

In all cases, what I looked for: what's available. Its not like there is much choice. You search for the country and then take the one that fits for the duration you are there. I usually get the smallest data that covers the whole time I am in the country. Unlimited is not worth it if you have WiFi at most places. When i stay for 1+ months its basically always better to get a physical sim. So I get a 3 day esim to cover the first days and then get a sim at a store (not the airport).

Never heard of the other one, but Saily is one of those brands that gets pushed by sponsored Youtubers so much that it automatically makes me suspicious. Basically, this comic.

When traveling I usually get two esims from different providers, for some level of redundancy

It’s fine. I’ve used Airalo a couple times. I suggest getting a little more data than you think you might need, and follow the instructions carefully when setting it up. Also disable data roaming on your main SIM after you set up the eSIM. Good luck!

My esim usage if for data only plans so I look for low price per GB and no expiry. The no expiry is due to me using the esim full-time with voip instead of a traditional cell service.
