In line with earlier rumors, T-Mobile confirmed on Monday that it will launch its first 4G mobile hotspot on Wednesday, April 13th. Built by ZTE, the T-Mobile 4G Mobile Hotspot will allow up to five devices to connect via Wi-Fi and share T-Mobile’s 4G HSPA+ cellular data service. The unit will run $79.99 with a new two-year contract, and a new $84.99 data plan will be available at launch. The new plan provides 10GB of mobile broadband per month with no overages — instead, data speeds will be throttled when the 10GB soft cap is reached.
