Slow and spotty.
I purchased one eSIM for myself and one for my girlfriend. We travelled from Bangkok to Bali with another couple. They used DTAC roaming and were able to use the Indonesian Immigration App upon arrival. Both of our JetPac SIMS were so slow at the airport (even after reboot) that we used out friends’ phone for Immigration. Quite a hassle. Overall, the coverage around Bali was not good. It was very slow. I tried to download a couple of YouTube videos on the way to the airport and I could only get one video (and not a long one) in 90 minutes! I do not recommend JetPac on Bali.
