Hi guys, new to MiFi's and this group...

I recently picked up a box of "electronic junk" and found a few of these 5510's in the bottom of the box. After charging the batteries and doing a hard reset, they all are active and are currently on unlimited data plans due to expire 9-18.

Any chance of "preserving" them? Kinda nice having 4G everywhere I go and on any device I have..
