Get Zong Wingle but check the signals strength at your location first. 3-4 signal bars are enough for it.
Charji Wingle works fine. I usually get stable 12-16 Mbps speed but it has downtimes as well often during loadshedding. Plus I have observed charji wingle that is offered these days does not properly switch back to EVDO. Instead it switches to 2G (CDMA) and does not connect because Vfone service has been shutdown. It's a software glitch in Wingle (no separate option available for EVDO only and CDMA only. But device can be locked on 4G). They also offer you a Huawei Car charger with it. (Charji cloud is not available. I have confirmed it from OSS. They told me it won't be available for some time probably because that has got some serious manufacturing defects).
