Ratings and reviews

Typical HK rubbish. Takes about 2 hours to set up, and there is no help at all. I guess there are restrictions on what passwords you can use, but it doesn't tell you anywhere what they are. So you just have to try to find one that will work. And because it won't let you attempt to login after a couple of failed attempts (with the password that you set, but wasn't accepted, even though you got a success message), you have to reinstall 10 times before you finally succeed.

Would like to buy a tourist eSIM, but it's not possible without first registering with a HK local phone number... How would a tourist have a local number?

stopped working and I cannot access my information both online and on the app
