Faulty service caused financial damage...
Sadly zero stars are not Possible. Used Etravelsim in Japan 2 times without flaws. I transit through Korea and bought an Esim for Korea as well 5gb for 30 days even though i just need it for one day. I followed the instructions as adviced in the mail. It worked two times before. For Korea it didnt work at first so i followed the troubleshooting-guide. It suggested restarting the Phone. I did exactly that but what i didnt knew is that certain Settings resetted and my actual Sim connected to mobile data coverage. I used some Apps that need Mobile Data to work a bit for Translation in korea before i got hit with a notification that i now have to pay 47,60€ to my Sim-Provider. As i just connected after restarting the phone and not changing any settings i expected that the mobile data usage was still set for the Esim. But it connected to the regular-Sim instead. All because i did exactly what was told in the activation manuals in the mail. Whats my fault is that i expected things to work after following the Troubleshooting guide and didnt doublecheck what the mobile data usage was set to. I want to mention again that i did exactly what was written down 2 times before and it worked great without a Problem. I contacted the support and even if the answers are increadibly fast they are no help at all as they take troubleshooting further... The problem is not that i dont have mobile data now for a day of Transit in Korea but that because of instructions provided i now have to pay at least 46,70€. I dont recommend at all anymore. Edit after the Reply from EtravelSim: Yes i know what happened. I described it before. It happened because i did follow the instructions that are send via Mail. I dont care about further Troubleshooting when the damage is already done. It occured because i restarted the phone as suggested in the mail instructions. The settings for prefered usage of mobile Data doesnt save. It was one day of transit in Korea i dont need the ESIM to work anymore. Your refund is something i did myself with buyers protection from Paypal.
