There are various ways you can do this . A lot of people start with downloading clockskins to desktop . Connect watch to pc and drag and drop into clockskin folded then re-boot
Here is another method
Forget the Geoapp . Its not great
Try watchdroid instead . You will find a whole thread on this in this forum .
If you have a sim card installed you can activate a data connection by turning on the data toggle . Its the one in the middle ( same screen as wifi / bt etc ) on your watch
Thanks
