I mostly travel around Africa & Asia (east, south east, central). Yeah, I used esim.dog with the HK break out IP and it was fine.
I guess my usage falls into two categories:
1. I have reliable wifi, and don't need to use mobile data for work
2. I don't have reliable wifi and I have to use mobile data for work.
If I'm in situation 1, then I don't really care too much. The cheapest junk esim works. If I'm in situation 2, I need a large amount of data and need a local plan.
I've saved your site though, never know what situation might come up. I don't know how esimdb chooses who to index, but I would try to get on there (I'm assuming it's free?).
I've spoken to quite a few travelers and they mostly fall into two groups. Those that use airlo or some other big provider or they use esim comparison sites to get the cheapest offer.
