Mobilicity's much-needed 21Mbps network upgrade may be almost at hand... with a catch. A leak to MobileSyrup reportedly has the HSPA+ network arriving sometime next week in tandem with an $80 Huawei E366 USB modem to exploit the new speeds. However, the Canadian carrier might just slap an asterisk on the end of that "unlimited" tag it's been using so far. Current customers may be relegated to a Basic Unlimited Data tier where any use past 6GB is potentially throttled; anyone needing full speed beyond that would have to either slap on a $20 Premium Data add-on or switch outright to a comprehensive $50 data plan, with both plans bumping the ceiling to 20GB. The two could remain better deals than for the major carriers, at least if you don't mind eschewing LTE. Nonetheless, any truth to the offerings might take away one more choice for truly unlimited data in the True North.
