We just ditched CDMA/Big Red & got 2 Nexus 5 without contracts, mostly for its GSM world phone features with HSPA+ and 4G/LTE - these D820's by LG will work on Sprint's network ... YES. We are covered if & when they merge - no worries about selling the devices in the near future.

Oh, yes - that $30 T-Mo prepaid plan with unlimited text, 5GB 4G/LTE data and 100 mobile minutes every 30 days is a best kept secret, for new activations online only.
