Airalo

Airalo worked okay at least in Manila. But speed is not that high at all and upload speed can be quite slow sometimes. I used it only for messaging, maps, Grab, etc. so was okay for me.

It's a roaming network provided by Singtel so it goes through Singapore with latency of a bit shy of 100ms.

If you don't mind the task of getting a local SIM and swapping it in your phone, you'll get better deal and better latency for sure. But as far as prepaid eSIM goes, Airalo does a decent job I think. You just have to lower your expectation a bit.

I was in Manila, El Nido and Coron. It worked well enough in Manila that I had no complaints. In El Nido, I had to manually select a network for it to work. Leaving it on automatic on the phone will choose the wrong network. In Coron, I had no reception once outside the main town. My wife had a physical SIM card and she had no issues.
