If your unit arrives broken

Cell2Jack does not list a separate manufacturer warranty. If your unit is broken, the fastest fix is Amazon's own 30 days return window: a full refund or a free replacement, no explanation needed. See returns and refunds.

Past that window, mail it in using the steps below and we will do what we can. We do not promise a fixed coverage period beyond Amazon's return window today.

Before you send it back

Almost every problem people report is a setup issue, not a broken unit. Check your power adapter, your cable, and your wall jack first. The help center fixes most issues in a few minutes.

If it is still broken, mail it back with a note that covers the problem, your order number, and when and where you bought the unit.

How to get a replacement

  1. Ship the broken unit, the cable, and a note with your order number to the address below.
  2. We send your replacement once it arrives and we confirm the problem.

Where to ship: Cell2Jack #119, 171 Main Street, Los Altos, CA 94022.

Outside the United States, please include a return envelope.
