That changes today with the introduction of “Unlimited Nationwide 4G Data,” an add-on for the company’s voice / text plans that includes throttle- and cap-free access to its HSPA+ airwaves (which are now up to 42Mbps in many markets). The package costs $20 for “Value” plans — those that aren’t tied to a subsidized device that you purchased directly from T-Mobile — and $30 otherwise, but the catch is that you won’t have hotspot capability.
That doesn’t sound like a horrible deal. T-Mobile will support a Galaxy Nexus while Virgin Mobile will not. Someone seems to get it.
