The service didn't work at all
The service didn't work at all. It was impossible to contact them. I sent an email to which there was no response. Was unable to chat through etravelsim.com. Instructions for my version of iOS were wrong. The step "Click on APN and write mobile data" could not be done, because there is no such option. They should provide full instructions for different versions of iOS and also be more accessible if a problem arises. A traveler depends on the esim to work when going overseas.
