I am having the same issue. It seems as though Verizon is treating these routers like the jetpacks now. After the 10Gb, they'll (supposedly) throttle you to 3G speeds. I actually lease several of these exact routers to my customers. The first three months of having this plan, I wasn't experiencing any kind of throttle. Each line that had the router on it used at least 60GB. Since the end of March, these routers have been nothing but pot ever since. I did several speed tests on them the other day, and each line produced the same result. The lowest speed I got was 1 kbps down, 5 kbps up. The supposed "3G" I was supposed to receive after the 10GB was nothing but a lie. But here's where the real problem really is. I made several phone calls to upper-level tech support, and got nothing but the run-around. I finally managed to get transferred to the business department, have no idea how that happened, but they were the most helpful surprisingly. I spoke to a nice representative who finally realized what the problem is. The Novatel Tassman router only has 2 radios inside it. One is the 1x, or voice radio, and the other is LTE, or data radio. What happens next explains exactly why you are receiving those terrible speeds, just like I am. Verizon actually sets the network to trigger the 3G modem inside a device once the 4G allotment has been used. I actually thought it was on the network side, but that only applies to the 22GB prioritization or safety mode. So basically Verizon doesn't throttle the speeds on the device itself, it triggers the 3G modem inside the device. The Tassman doesn't have the 3G modem in it, so it picks the 1X, and that's why you are experiencing "2G" speeds instead. They offered to exchange my router for a new jetpack. Very dissatisfied with verizon, Never seen a company who is so stingy.
