I have a usb720 internet modem. I do not EVER text with this modem. EVER. I am getting text spammed. I have to pay for every text I receive. Verizon tells me I am unable to block texts with this modem without upgrading my account. I say BULL. This amounts to extortion. Either verizon gets paid from me receiving unsolicited text spam, or verizon gets paid for me to upgrade my account. Make it stop or I am going to cricket.
