This device hooks to the internet via an Ethernet cable and helps your 3G and4G devices attain more bars in challenging cellular environments.
The unit is new and unused in the original box and with the original accessories. I bought it to help with cell signal on an island where we had a place, but then we sold the place and thus have no need for the AT&T device.
These are $499 new on Amazon and used ones aren't much less.
"Is it still available?" e-mails will be ignored. Cash only. No PayPal. Will not ship.
Thanks for looking!
