To enable 2G networking you have to follow these steps:
Settings -> Mobile Data -> Mobile Data Options -> Voice -> Check 2G
I hope I was able to help you.

2G disable option has been pushed from Apple during iOS 11.3 update for iPhone 6 and above Without prior notificactions.
2g toggle option is available for iPhone 5S Users.
Apple should consider to enable this 2G option during their next update for all iPhone users.
I personally prefer using 2G signals when I am at home and work (Use personal Wifi for internet) this will enhance the iPhone battery life and iPhone performance
how can I turn off 3g and turn on 2g in ios 11.3?
