Pre-paid carrier GoSmart Mobile adds $30 unlimited talk, text and data tier
The cheapest tier cost $25 a month and includes unlimited talk and text plus the 4G LTE Facebook connection. The $35, $40 and $45 tiers all come with unlimited talk, text and data. The $35 plan gives you 2.5GB of 3G data before you are throttled to 2G speeds. The $40 and $45 plans come with 5GB and 10GB of 3G data respectively. Once that data is consumed, users are throttled to 2G speeds.
GoSmart says "all monthly prices are as-advertised (without any hidden fees or auto-pay requirements), and come without any ridiculous strings attached." And if that sounds a lot like something T-Mobile would say, it turns out that GoSmart is a T-Mobile MVNO. That means that GoSmart subscribers are using the T-Mobile pipeline.
If Facebook is your passion and you don't mind a 3G or 2G data speed for your other connections, you might be able to save some big bucks with GoSmart Mobile. To check them out, click on the sourcelink.
