I have a customer that has an SOTG and despite loading the latest firmware (1.0.29) and following the suggested modem configuration, he simply cannot get the U620L modem to work. It will connect to the Verizon network, acquire an IP address, then after a few minutes, drop the connection and go through the authentication process again, acquire a new IP address, work for a few minutes then repeat!! The SOTG works just fine with an ATT modem but the customer wants to use his unlimited Verizon data account.
I have seen quite few threads on your forum regarding problems using the U620L with the SOTG that do not appear to be resolved. Since I had confirmed to the customer that this modem does work based on one of your suppliers (3GStore.com) I’m on the hook to provide a solution to him. One interesting piece of information - his iPhone was using the iHeart Radio app to play music over a Bluetooth speaker and every time the U620L modem disconnected from the Verison network, the Bluetooth app would disconnect from the Bluetooth speaker.
I really need you to get a solid fix for this problem ASAP
