know the type of network (2G, 3G, 4G) in a javacard application

Question

I am developing a javacard applet and I need to know the type of network to which the phone has been connected (2G, 3G, 4G), does anyone know if that can be done with any javacard or java method? Thank you. Regards Jorge

Answer 1

For know the network wich the phone is connected i have used a Provide Local information command with Device Identities equal "06", in TS 102 223 you can see Provide Local Info and that the value '06' for Device Identities is Access Technology. When this command with this value reaches the phone it will return the network to which it is connected in the tag Access Technology, if this value is equals '00'=2G, '03'=3G, '08'=4G
