I am mainly interested to know about connections such as 2G/3G/4G and main
protocols that are available such as GPS/GPRS
Some people say that they can spy only sim card/card code such as in bank
cards etc,some say that they can spy socket itself and some say even interact
with it.
Can someone provide basic explanation on this topic and for example:
If i would be to use 3G/4G network modem for connection instead of 3G/4G
phone with wireless hotspot ,how much secure would i be?
Regards and have a nice day.
