AIS eSIM2Fly Roaming Network

If you are wondering which networks AIS SIM2fly will connect with while abroad, we’ve compiled some information from AIS.   If more than one country is listed, that means the SIM2Fly will choose the best available network at the time.   This can be quite useful since you can view it as back up coverage.   In larger counties there are many areas where only one of the carriers provide coverage, so have the benefit of automatic carrier switching means you have the best chance at coverage when compare with a single local SIM.

Manual Network Setting

AIS do mention it is possible to manually select your network.  If you find you are in a location and your network choice is switching between carriers or not connecting, you can do a manual network selection.  Go to Settings > Cellular > Network Selection.

Bridge Alliance

AIS is a member of Bridge Alliance and together with the Bridge partnership AIS will roam with any of these partners. Mostly focused on Asia, this is a partnership of Asian telecom companies.   This means and AIS eSIM2Fly will roam on either China Telecom or China Unicom in China – which ever is available and preferred.  Other notable carriers include Softbank Japan, SK Korea, Singtel Singapore and Airtel India.

AIS Worldwide Roaming Partners

AIS has published a list of the worldwide roaming partners.   While updated infrequently, it will give a rough idea of the network your eSIM2fly will be connected to in each country.  Multiple carriers in each country means any of them will work.
