As above. In iOS 9?
Can you supply the name of your Carrier so people who are on that particular Carrier can check theirs and report back.
I'm on O2 Uk and the toggle remains on iOS 9.0.2
On Vodafone IT I can only enable/disable 4G (LTE) or enable 4G for Data or for Voice/Data.
2G/3G/LTE switch is gone since iOS 8....
Thats what i'm seeing too.
it's a carrier thing. am on M1 (singapore) too. anyway they're doing away with 2G in singapore soon as far as i heard
