![]() Unfortunately, the PPP functionality does not support data connection handoff between the EVDO and LTE networks, so you have to break the connection and reconnect with the appropriate ATD command when necessary. Connections to the 3G EVDO network can be made with the standard ATD#777 command. You can connect to the LTE network using standard ETSI 27.007 GSM-style AT commands like AT+CGDCONT and ATD#99* and such. Of these, only the AT command and the QCDM ports are really usable in Linux. The UML290 exposes four USB interfaces: a standard CDC-ACM AT command port which supports PPP, a QCDM port, a WMC port, and a raw IP network port. ![]() Inside is a Qualcomm MDM9600 chipset providing both CDMA 1xRTT and EVDO on the standard North American 850 MHz Cellular and 1900 MHz PCS bands, and LTE on Verizon’s Upper 700 MHz C-block band. Despite being quite large (over twice the size of a normal 3G modem) it’s not a bad device and performs quite well in speed tests. Along with the LG VL600 this modem was the launch device for the Verizon 4G LTE network late last year.
