I tested a few esim providers for myself and Esim4Travel was one of them. Easy to install and use, no issues. Just read the description and check if the network operator has coverage where you plan to go and you'll be fine. Very good price, would buy again.
Side note: Like with most other esims, traffic is routed through another country (it was Poland for me), so ping was 100-350ms but I had no issues with that (just like most people).
Used MicroEsim in the US with no issues. I always had reception. More affordable compared to many other providers.
Side note: Like with most esims, traffic gets routed through another country (in my case Poland with Polish IP). Expect ping of up to 350ms (in my case). Most tourists/travelers will have no issues with this.
It was nice to have connections all over the places I visited in the USA It was really easy and fast to install it was really easy and fast to install, the connection was great and the fact that you get unlimited data for such a great price actually works fast makes it so much better than the usual sim you would buy at the airport where you only get a few gigabytes.
Ran on AT&T in US and speeds were poor ~ 5Mbps down / 0.05Mbps up with 500 + ms latency. Data traffic is routed through Israel which is why the latency is so high from within the US.
