Amazon カスタマー 5 I set it up on an old pocket wifi which I had to have unlocked from the carrier. It doesn’t come with instructions for pocket wifi but the email support staff were really helpful. We couldn’t figure out why it wouldn’t set up but finally I read somewhere that you have to have the website on pc mode. Make sure you know all your passwords for your wifi as well. Make sure you don’t put in too many wrong passwords or your SIM card will lock.
