Works just fine. Was able to transfer my old number over without a hitch, took just a few minutes for it to fully activate. I'm happy, and so is my Nexus5

Works great.  Glad I could find this for my old phone.

Really fast and the transfer was quick and painless.

I will update as to the longevity, but so far there has been a huge boost in performance.

Arrived in time. Configured without an issue. Unit is working good. It safes me time for the backup transfers around 35% compare to the old unit.

Transferred data from Quicken Elements.  Works well except it carries my 403b as a negative quantity.

Worked fine right out of the box. I put my old SIM card into it and it worked right for a week and then stopped. Talked to AT&T, it turns out I need a new SIM card (which they gave me at no charge) since my old SIM card still said Cingular on it, that's how old it was. Working fine now.

Works really well. I used it with Google Voice initially, and that worked well. But when Google Voice stopped supporting this, I switched over to PhonePower (for $35 per year), and that is working very well as well.

For a while I had two phone lines, which was fun as I could switch from one number to another to confuse my friends. In short, the multi-line support of this tiny box works well.

The User Interface via the web interface is nice too, and so is the help pages when I needed explanation.

The only caveat is you will want to update to the latest firmware. I initially couldn't get it to work until I updated the firmware.

Two more tips to ensure fewer dropped calls:
- Set it up as a static IP (this can be done via the built-in web interface)
- Set up a QoS (prioritized network traffic) on its IP address on your network router

It arrived earlier than expected and its easy to activate. I ported my number in a few mins.

Unable to transfer old phone number and minutes. According to Tracphone, it has to be done before the phone is activated or it can't be done. This one is a paperweight and headed for the trashcan.

worked perfectly. Just needed to relocate an internet line from room to room and this worked lik a charm. No problems

Perfect for connecting an older Android phone with a newer one. Was able to transfer files just fine. I was able to charge the older phone using the cable as well.

It works, transferred files through the adapter fine. Fast enough for phone and music usage, haven't had any problems yet.

With Double Minutes and Bonus Codes, this product has worked for me for about 9 years.
They make is Semi-easy to transfer minutes from old phones to new phones and most of their phones are only a few years out of pace with the Big Guys.
But, for $90 a year for service I'm willing to suffer a bit.
