I am using iPhone 7, iOS 12.0.1 and I cannot find toggle to switch between data networks 2/3/4g. How and where do I find switch, is there any way? Its always in 3g mode and due to which battery drains real hquick even if data is off.
There never has been such a switch. The network selection is dependent on your carrier.
Often iOS update include carrier updates which can control whether switching cellular types are allowed. Many carriers are phasing out 2G so they can reuse the frequencies for more efficient newer technologies. They want to reserve the limited remaining 2G for phones that can't use anything newer, so they disable 2G option in carrier updates for phones that can use 3G or faster networks.
With a modern phone, there shouldn't be much difference in battery usage between 2G and 3G, anyway.
Few hour ago I updated to iOS 12, before this (using iOS 11) I had these 3 2/3/4g options so its not carrier dependant at all. Not a good upgrade, draining battery like ****.
Cannot find switch/toggle to 2g/3g/4g
