- Firstly, ensure your antenna is fully extended with an unobstructed view of the sky.
- Check to see if there is any signal strength, using the relative signal strength indicator bars displayed in the upper side of your display. The more bars that are displayed on your mobile handset, the better the signal.
- If there are no bars at all, check whether you are outside the coverage area.
- You should also check if your SIM card is valid, and whether your new network is authorized.
Please note: Mobile Satellite handsets require a clear view to the sky. If you are inside a building, tunnel, or other structure that limits your view of the sky, the satellite signal may be weak or unavailable.
