Firstly, please note that an internet connection is not required to use AIR³ as a flight instrument. However, if you do not have an internet connection, you will not be able to access online features such as automatic airspace downloads, live tracking, QNH synchronisation, thermal map downloads, …
To access the internet, you can either use a SIM card or set up your phone as a hotspot. However, note that using your phone as a hotspot can result in an unstable connection and drain your phone’s battery, which can be stressful before taking off. Therefore, we strongly recommend using a SIM card.
Depending on how you use AIR³, you may only need a small amount of data. For example, if you only download airspaces and use Livetracking, you will need less than 1 GB per year.
Some operators offer a second SIM card as part of your existing plan. Others offer prepaid SIM cards with no time limit, such as BNESIM. Check your region and click on ‘Lifetime data’.
You can also get an eSIM card from eSIM.me to add eSIM features to your AIR³. Once you have this card, you can purchase any eSIM plan.
