I am about to purchase a Novatel MiFi 2352 or 2372. The MiFi shares a 3G data connection as a wireless access point and it’s battery powered. The difference between the 2 models is this:
MiFi 2352 uses the following bands: Tri-band HSUPA/HSDPA 900/1900/2100 MHz and Quad-band GPRS/EDGE 850/900/1800/1900 MHz. The MiFi 2372 however is: Tri-band HSUPA/HSDPA 850/1900/2100 MHz and Quad-band GPRS/EDGE 850/900/1800/1900 MHz.
According to this page: STC, Mobily and Zain all use the 2100MHz band for 3G.
Qanawati (my channels) is a new service from Saudi Arabia based company Remal IT. The service allows you to check your flight reservations status via SMS.
You can check for available flight reservations on the following airlines: Saudi Airlines, Nas air and Sama. You can also check for reservations on all airlines using IATA, check the status by flight number and check the arrival/departure activity in Saudi airports.

The service is charged by each individual SMS message. Currently only works with Mobily and Zain cell networks. STC is “coming soon”.
