Bought this receive 3G service because newer models support only 4G LTE.
It works well, but there are caveats:
1) Verizon will terminate 3G service at the end of 2020.
They've already extended that deadline once, however.
2) The USB connection is quirky.
The modem springs to a 45 degree angle and will only function of it remains
if it remains near this detent.
