here's the thing: some carriers have the option to enable 2G regardless the ios version, while other carriers had this option from ios 8.1; but starting ios 9.3 this users lost the ability to enable 2G
So it seems that the truth is in the middle... This unhappy combo: having a newer version of ios than 9.3 and a carrier that is influneced by the version of ios will leave you with the impossibility of enabling 2G.
AT&T will have completely shut down it's 2G network by January, after having announced that would be the end date for their USA 2G network some 3 or 4 years ago. T-Mobile has (reluctantly it sounds like from the press) extended their final shutdown to 2020, but is largely trying to restrict 2G to select users (e.g. alarm companies who need to transition fixed radio transmitters). Rogers is the only company in Canada still running a 2G network, but only for another couple of years.
Since most of carriers have not sold 2G only consumer devices for years, in anticipation of shutting off those old networks, they see no need to support the feature on their consumer devices. For the most part, legacy 2G networks are only being kept up for commercial users, and yes, the carriers are removing the ability for consumers to utilize 2G since they are getting rid of 2G and wish to reclaim that bandwidth with the FCC for new technologies. So you are right, they don't want you even trying to use 2G connections, even where still available, as they want to be rid of that legacy technology (and now largely under utilized bandwidth) as soon as they can. Keeping it active is actually holding them back from updating and expanding newer services.
