Industry experts are skeptical about the viability of the few remaining unlimited data plans, to say the least. And for good reason. It’s hard to make the numbers add up in the long run. High-speed connections like 4G LTE have opened up a whole new world of mobile capabilities, most of which use a lot of data. Continuing to offer “all you can eat” plans at prices competitive with measured plans just isn’t practical. Verizon Wireless and AT&T know it. And it looks like T-Mobile has realized it, too. That’s why T-Mobile will not allow mobile hotspots on its unlimited data plan. Customers must have a throttled plan, which is at a much lower speed. Another indication that unlimited data just isn’t viable in today’s data-intensive mobile world. Consider a Share Everything plan.
