Prepaid with UM175

[jim768]

I have a UM175 device that I use with prepaid mobile broadband.  It works fine except that I have not found a simple way to activate a session with it.  I always end up having to call in and talk to a person.   There is supposed to be a way to do it from VZAccess Manager but I do not seem to have that option.  I am using the latest version recommended for that device, 7.2.1.2 (2420b).    I am hesitant to upgrade to a newer version because the web site gives the impression that the version needs to be matched to the device.   Does anyone know if there is a version that works with UM175 that supports prepaid session activation or if there is another automated way to do it?      Jim
