Avoid Jetpac!
Really poor service. I bought the jetpac esim to cover 6 weeks in Indonesia but had barely any coverage for the whole time. Set up was problem after problem with very poor support (customer services constantly terminating query due to lack of response within short time frame). No signal or internet for days. Ended up on a hotspot on my partners phone (different provider) or searching for WiFi to make basic comms. I eventually cancelled as soon as the data package was used for an alternative provider, which has been reliable. Just relieved I wasn't travelling alone as the lack of connectivity would have left me in a very awkward position. Avoid at all costs, total waste of money!
