I have recently purchased a new usb modem from MTS. I have seen that there are two options available on MTS applicaton which are broadand and CDMA 1x. I have information about the broadband but I don’t have any information about the CDMA 1x. In broadband mode internet was working fast and fine but when I switched to the CDMA 1x mode then internet became very slow and I also got frequent disconnection. Somebody please tell me about this CDMA 1x.
