The first thing that is helpful to do is reset the hotspot. Hold down both the WPS and Power buttons simultaneously for at least 3 seconds and give it a try. If there still will be an issue, check the APN settings via the web interface of the hotspot.
Connect to the hotspot via any WiFi-enabled device and open http://mobile.hotspot (or http://192.168.1.1 or http://192.168.0.1) in your browser. The default username and password is “admin”.
Go to Settings> Profile Management. In the input fields:
Name: Keepgo
APN: internet.keepgo.com
Username: leave blank
Password: leave blank
Save settings, reboot the device, and start surfing. In case of any issues or concerns please contact our Customer Support Team via email (support@keepgo.com) or chat on our website.
