Very bad experience with Jetpac!
I bought an e-sim for China, followed all their instructions, but when I activate it and select the rom manually, no Internet connection at all! I did everything the customer care told me to do and all the procedures they described on the website/app, but not even 1 second of Internet connection. I switched to another e-sim, and I used Internet without issues! Jetpac does not have even a telephone number for customer care in China, only through whatsapp (blocked in that country) or email (you will not receive any support during the weekend). I will not use Jetpack for all my future travels at all and I do not recommend it to all the people I know!
