Simple Mobile, an MVNO running on T-Mobile's HSPA+ network, has lowered its top-tier of service from $60 to $50. In addition to the price drop, the carrier is also claiming that the network is now faster, though it hasn't qualified that with any technical details. One user on HowardForums — a popular haunt for cell service technicians and enthusiasts — posted what he or she claims is a dealer email from Simple Mobile, saying:

Prior to today, Simple Mobile's High-Speed Unlimited plan offered common HSPA+ speeds until the user hit a nebulous and unpublished limit that hovers around 2GB, according to some HowardForums users. The $40 plan — which also includes "unlimited data," though not at "4G speeds" — was also rumored to be using T-Mobile's throttling mechanism to limit users to 120KBps. No real-world tests of either the $50 or $40 plans have surfaced as of yet, but we're sure that customers won't turn down faster speeds at a lower price, even if Simple Mobile's language is a bit ambiguous.
