For those that don't know, US Mobile is one of just a few MVNO's that offer A La Carte pricing. With A La Carte pricing, you get to custom build your own plan, you only pay for what you need. If you don't need talk, you don't pay for talk, you just pay for texting and data.
The first change to discus with US Mobile is that they reduced what they charge for 2.5 GB of LTE data. Previously the charge was $25, but now it is just $20. The other change is that you can now get 6GB of 4G LTE data for $35 instead of 5GB. If all you need is data on T-Mobile, you'll be hard pressed to find a provider that offers more data for less money on the T-Mobile network.
A summary of US Mobile's updated plans can be found in the infographic below.
One thing to note is that the prices listed do not include taxes and fees. Furthermore, there is a $2 per device network access charge. This means that the true cost of 6GB of 4G LTE data will be $37, plus any taxes and fees which will vary based on where you live.
