AT&T Unlimited LTE Hotspot $20 without AT&T phones

Hid my Mobley three days ago so no one would steal it, while I was gone. Forgot where I hid it and spent hours and hours looking everywhere. Almost panicked and about ready to call ATT to put the acct. on hold. Was walking down the hall and it just hit me where I put it for safe keeping. It's bad to get old...
