Rated 2 out of 5 by from Crap. I got it from Cricket. Cheep phone nothing more to say.

Rated 1 out of 5 by from Newest Update Ruined Phone The phone was good for the cost until the most recent software update (8/20/2020). Now cannot get it to work with most Bluetooth devices, including a brand new stereo it worked with prior to this update. And I don't mean a new to me stereo with old technology itself, I mean a brand new top of the line stereo that's currently useless since my Bluetooth no longer connects to it or other devices it was previously paired with. Removed the pairing and redid it now it suddenly cannot even find the stereo as an option to connect to. Trash update that honestly was unnecessary. Cannot see anything else on my phone that has changed or positively impacted by software update at all.
