1. Check the coverage of your XPLORA. You can find the indication for coverage in the upper left corner of the screen.
If you see dark gray bars or a crossed phone symbol it means the XPLORA doesn't have reception.
However, full bars on the watch don't necessarily mean that the watch has sufficient coverage to establish mobile data connections. To check if the watch is able to access mobile data, please go to the Menu "My watch" and open the sub-menu "Info". If it says "Services available" or "Services of access" under Network State, the watch has sufficient coverage to connect to the internet.
Try to get into an area with better coverage. Often coverage varies even within the same apartment. Usually it is better near the windows and best outside the building.
Please note that XPLORA 1 and XPLORA Care are using 3G, unlike smartphones who most often use 4G and 2G. In addition, XPLORA watches are designed to be carried directly on the body, which means their antennas can't be as strong as the ones used in smartphones. Even though your smartphone might have full reception, your XPLORA can experience insufficient coverage.
If you have tried all of the things above and the watch still shows "Waiting Service", you might not have sufficient coverage to use your XPLORA with the current SIM-card. Please try a different SIM-card.
