Speedtalk has a $5 monthly plan for cell phone service. You can get their preloaded SIM at Amazon for $5 plus $4 shipping.
The service level includes 250 minutes OR 250 text or 250MB data per month. So its pretty limited, but for $5 its a pretty decent offering for light users.
You can also get 12 months of service from Speedtalk for $60 at Amazon with free shipping. That works out to $5 per month and the shipping is free. However it does NOT have rollover so the monthly allotment is use-it-or-lose-it.
Speedtalk is a reseller that uses the T-mobile network. I haven't used them myself.
