In-flight roaming charges

You can now use your Mobile in the Sky with In Flight Roaming

What is it?

In Flight roaming is a new service in where some airlines now have Mobile Phone transmitters fitted onto their aircraft. This technology means that Mobile phones can now be used on flights (where the airlines support it).

How does it work?

An aircraft installed with a mobile phone transmitter can relay calls to and from mobile phones and these calls are routed by satellites. The satellites route the calls to and from terrestrial networks, thus connecting the mobile calls to telecom networks on the ground.

How do I use it?

As is currently, you will be instructed by the crew on the ground to ensure that your phones are switched off before departure. You will only be able to use the service when the aircraft is airborne and has reached a cruising altitude. You will then either be informed by the crew, or a Mobile phone light in the panel above your seat, that you are now permitted you to use your phone.

All Voice, data & SMS use is possible, but some services (such as voice calls) may be prohibited by the Airline. If all services are permitted by the airline, in some cases the airline may limit Voice use to a small number of passengers at any one time. This is to reduce cabin noise.

How much does it cost?

As this is a new technology and there are a number of commercial organisations involved to provide the service, the costs are charged at a premium service.
