Ques. Dear TechTantrik,

I have got Airtel 4G Connection with ZTE MF29 router. Since I am not too happy with airtel service, I am planning to get reliance 3G Pro datacard. However, I am told that the Reliance 3G Pro dongle does not allow you to get the sim card out.
How can I connect the reliance 3G Pro with ZTE MF29 router?
