I bought a phone from them for $10 and it works great for calling and texting. They usually always have deals too!
If you use my code when you buy a phone you will get $20 account credit. The code is this : mike181
The monhtly plan that I have is just $13.99 a month so that's a bargain too in my opinion.
If you know of a better cellphone service let me know! Thanks.
