Linda there is no web site, only an app. No, it works like a regular phone.
Use app to check your account and number of members in your group
We have used it mainly West Coast, from Anacortes, to no where Az, and have been very happy with the service. We also haven’t had any issues using it as a hot spot for multiple devices.
it is not an AT&T or Vz though. You cannot pick up the phone and speak with someone. The only way to get in contact is through chat, on the app
i have had it a year in November. Check your phone compatibility, they overnight you a new SIM card, activate, good to go
