Hi, I need to leave my country for a couple days, but my cellphone plan doesn’t cover data oversea and I don’t like to rely on WiFi. A relative suggested that I try Saily, which is an esim provider that you can load with whatever you need in the country you’re visiting but I’m again reluctant to use an app when I don’t know how trustworthy it is. Has anyone ever faced the same issue? Should I simply let go of my internet connexion and enjoy a couple days off the the internet? Cheers and thanks for your help
