The device requires a SIM card - you will not be able to activate it without a SIM. If you are swapping from another Verizon 4G device you can use your existing SIM, but if you are swapping service from a 3G-only device or if you plan to sign up for Verizon's month-to-month service, you can add a SIM card here.
Add a SIM card (optional) - details

This refurbished no-contract modem is "like new" (no packaging included) and is perfect for:

  • Customers wanting to sign up for Verizon's month-to-month service (simply call Verizon after receiving the modem to set up service and receive a SIM card [or add a SIM card above])
  • Existing Verizon customers who want to swap to a more current device or need to replace a lost/broken device, but don't want to alter their contract (purchasing this device will NOT extend or alter your Verizon contract - once you get the new device, you can insert your SIM if you're swapping from another 4G device, or you can contact Verizon to do an "ESN swap" and get a SIM for the USB551L [or add a SIM card above])
    • If you are swapping from a 3G-only device and currently have an old unlimited plan, you will NOT be able to keep your plan. Switching to a 4G device requires you to choose a 4G plan.
    • The USB551L has a standard-sized (2FF) SIM slot - if you plan to use a 3FF microSIM, you'll need the micro-to-standard SIM adapter.
  • IMPORTANT: This is a VERIZON modem - it cannot be used for any other service providers.
  • You may need VZAccess Manager to activate your modem - if you don't already have it installed, you can download it at

connects easy with no problems and fast. I like the built in slim jack too. I had no problems registering it with Verizon and clean paperwork from made it easy and no surprises.
