In some cases your hotspot might not be detected by the device. In this case make sure the option ‘Allow others to Join’ is enabled. Besides that, it is also essential to know whether the provider of your sim card enables creating a personal hotspot. You can try to connect other phones with your personal hotspot to see whether that works. As a final check, see whether your internet connection is strong enough. If you are still not able to connect to the hotspot, don’t hesitate to contact the Envision Customer Service team.
