可通过获取 MNC 来区分，中国移动系统使用00、02、04、07，中国联通GSM系统使用01、06、09，中国电信CDMA系统使用03、05、电信4G使用11，中国铁通系统使用20。
获取方式：

#import <CoreTelephony/CTCarrier.h>
#import <CoreTelephony/CTTelephonyNetworkInfo.h>

CTTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [info subscriberCellularProvider];
NSString *mnc = [carrier mobileNetworkCode];
