I can confirm that we do offer a $70.00 Unlimited Nation Wide 4G Data plan for prepaid customers. The plan and more details about the plan can be found here: http://prepaid-phones.t-mobile.com/monthly-4g-plans. The plan listed here for $70.00 per month offers Unlimited Voice, Text and web with no data speed cap. I hope this helps.
Hmm. What is the business theory where it makes more sense to offer pre-paid customers much better rates than long time "regular" post paid users? We have two lines, and each using a tiny fraction of our 5G of data. We pay about $77 a month on each line. We also only use a couple hundred of our unlimited text messages.
I just cut back our data to 2G a month on each line. We use a quarter or less of that. That will save $15 a month on our next bill. That means we can no longer tether our laptops to our phone - but that only came up once a year or so.
This is just a "rant". We are pleased with the service and features like wifi calling we can use overseas.
