I got my Three 4G Mifi today and put the SIM in, turned it on but for some reason the connection doesn't show up on any of my other devices like smartphone, pc or TV.
When I had mine delivered around 4 months ago the SIM card wasn’t active. So if the device is showing 2 red lights on the front you’re in the same situation. Mine took three days to be activated and I then had 2 GREEN lights showing and all was good. So if your device is showing 2 red lights,your sim is yet to be activated. If it’s showing 2 green lights then check the device WiFi name which will be displayed on the inside under the battery. Also check in settings to ensure your WiFi network hasn’t been set to hidden. Good luck
