NOTE
‡
If the SAT icon is blinking or the displayed service area
appears to be incorrect, you may not be able to receive or
make SAT calls - in this case you can update the SAT
registration manually.
‡
The SAT registration only works while your Thuraya XT DUAL
is in satellite mode (Menu > Network > System preference;
see next chapter).
A very powerful function of your Thuraya XT DUAL is to use the
phone either in satellite mode or in GSM mode which will give
you highest flexibility no matter in which area you are travelling.
And to make the usage even easier you can select the network
mode manually or you can set your preference and let the phone
find your preferred network mode (SAT or GSM) as soon as it
becomes available.

while in GSM mode. The phone will then switch to SAT if the
service becomes available.

to a GSM network available in your area. Which GSM network
shall be selected can be set in the menu 'Preferred networks'
