EFF (Electronic Frontier Foundation) don’t budge: Apple does not offer any option for disabling 2G on its iOS devices, which would pose a major security problem. Conversely, Android 12 finally has an option to deactivate the 2G network (emergency calls can nevertheless pass), a novelty warmly welcomed by the EFF.
The first iPhone was only compatible with 2G (while 3G was available). 2G remained the default network on the iPhone, and it is still not possible to deactivate access to it
Why these virulent criticisms will you tell me? Quite simply because 2G is based on a network protocol that is far too old (1991) to be secure. The flaws of 2G are numerous and remain possible passageways for pirates and cyber-robbers of all stripes. The EFF thus notes that 2G uses a weak and ineffective encryption technique against remote attacks (on-the-fly call interception), that the antenna is not authenticated on the mobile (a hacker can impersonate for a 2G antenna) and that it is even possible to downgrade a 4G call to 2G in order to better exploit flaws in the weakest network.
Will EFF’s appeal be heard by Apple? Nothing is less certain, especially since in many countries (including France), 2G is the default network (especially for emergencies) and the pressure is low, both on the side of operators and politicians, to impose an option to deactivate the 2G network on mobile (which would force Apple to do the same on iOS).
