I have PTCL Charji device. Telenor MiFi device costs Rs. 2500. I am wondering, if I need to buy the MiFi device as well or if I can just get Telenor 4G sim and put it in PTCL Charji device and use it. Does anyone have any experience with this? I already have a 4G device, it'd be great if I don't have to buy Telenor's MiFi device too.
