Walmart offers the refurbished Straight Talk U240C Unimax Mobile Wireless Hotspot, model no. STUXU240CR.MB15, with a 1GB Data Plan for $19.99. Choose in-store pickup to avoid the $5.97 shipping fee. Factoring in the free data's value, that's a savings of $20 and the best deal we could find, although last month we saw a new unit (but without the 1GB of data) for $10 less. The hotspot features a web interface and connections for up to five devices.
A 1-year warranty is provided, although it's unclear who supports it.
