A few of the modem I've tried cause the sound quality on the other end of the call to sound like I'm calling from a cave. Why is that happening ?
It is not clear to me if some of the modems are pre-set to utilize only certain frequencies and not ANY frequency supported by the hardware.
Is it possible that a modem was created for a specific carrier and thus only supports the frequencies used by that carrier?
Is there an app or any other way to check what GSM & 3G bands are actually being used by the modem in real time ?
