Please can anyone here help by telling me what to do, I have a problem using mtn sim on my HSDPA Universal USB Modem. It was working before i removed my mtn sim to make call, but now its having issue with the mtn sim or any other mtn sim. the universal hsdpa usb modem can hardly see the sim while it sees other netword sim easily.

Hi guys please isn't there anyone here who knows how to fix this?

you have not told us your problem

The modem is not recognizing any mtn-sim. It was properly browsing on it before, after removing the sim to make call with it, and i inserted the line back into the modem, it started having issue with seen the sim, when i click connect it will show authenticating for a while and disconnect, its not connecting with it any more, i still have bundle on it and it hasn't expired.
