What network an iPhone is connected to (LTE vs GSM). How to confirm this ?

+6 votes

With the release of iOS 6 and iphone-5 I'm trying to figure out how my app can know if the phone is in LTE mode vs GSM mode.

I haven't seen any updates to the Reachability API which can give whether it is connected to Wifi vs WWAN but I need to know what kind of WWAN connection it is.

Any ideas?

For iO6 and below models, you cannot do this.

As of iOS 7, you can find this out using the

currentRadioAccessTechnology property ofCTTelephonyNetworkInfo in the CoreTelephony framework.

#import <CoreTelephony/CTTelephonyNetworkInfo.h>

CTTelephonyNetworkInfo *networkInfo = [CTTelephonyNetworkInfo new];

if ([networkInfo.currentRadioAccessTechnology
isEqualToString:CTRadioAccessTechnologyLTE]) {
// ... }
