I recently switched to Ting, I don't do contract phones, T-Mobile's signal at my house sucks ass, and the customer service at VM and Boost (being the same outsourced indian buffoons) is abysmal.
Went to ting, got a discount on my phone (samsung transform ultra) it took a little while to arrive because they had them on backorder, the phone actually was cheaper then the same phone on boost...
Unfortunately when it arrived the phone was damaged and could not be activated.
Sounds bad but wait....
Quick call to ting, no holding or automated system, they troubleshooted the phone to check the problem (the phone looked fine) once it was established that the phone itself was the issue they issued an RMA.
2 days later my new replacement phone arrived via fedex and the original one was shipped back to them free of charge (of course)
Phone was activated and haven't looked back since, coverage is great, made better by the fact that there i free roaming onto Verizon for talk & text
Last month's bill was $27, admittedly I'm not a heavy phone user and if you are it may work out more expensive than one of those "unlimited" plans, if you're not you could save quite a bit.
The following link will get you $25 off a phone when you order:
