Verizon 4G Configuration

The following steps were used to configure a Pantech UML290 4G modem (Verizon) to establish a connection using gnome-ppp and may be useful for other models with some modification.

1. Install gnomeppp by opening a terminal window and entering "sudo apt-get install gnome-ppp".
2. Right-click on the Applications menu and select Edit Menus. Locate GNOME PPP in the Internet category, select it, then click Properties to the right. Modify the Command field to read "gksudo gnome-ppp"
3. Start Gnome PPP and fill out the basics, entering the username as "XXXXXXXXXX@vzw4g.com" (replace Xs with the phone number associated with the modem), set the password as "vzw" and check Remember Password, and enter phone number "*99***3#"
4. Click Setup. In the Modem tab enter Device "/dev/ttyACM0", select USB Modem as the Type, and enter "100000000" as the Speed. At the bottom of the window uncheck "Wait for dialtone". All other settings on this tab should be correct by default.
5. Click on Init Strings and enter the following:
   Init 2: AT Q0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
   Init 3: ATE0V1
   Init 4: AT+CPIN?
   Init 5:AAT+CLCK="SC", 2
   Init 6: AT+GCAP?
   Init 7: AT+CMEE=1
   
6. Close the Init Strings window and switch to the Options tab of the Setup window. Make sure everything on this tab is unchecked EXCEPT "Check Default Route" and "Ignore terminal strings (stupid mode)"
7. Close the Setup window, connect the device if it is not already connected (wait a few seconds for it to initialize), then click Connect.

If all went will the modem should connect, though it may take roughly 10 seconds after "Connected" appears for internet connectivity to become available. If it appears to be connecting but you are not able to reach the internet, make sure there are no other active network connections causing confusion; if you find there are other network connections active be sure to disconnect and reconnect via gnome-ppp after disabling the other connections.
