Probably the cheapest smartphone around right now.
. I bought one on black friday for $10 and have used it when mine is in the shop. Ok, it only has 1 GB of ram and 8 GB storage, although it does take a 32 GB micro SD. Hey, it’s only $15. I was able to easily unlock it for T-Mobile, although some have had trouble doing the free unlock lately.
Here are the specs
