Sprint mobile virtual network operator CREDO Mobile on Monday announced the upcoming availability of the Samsung Galaxy S5. Starting from May 1, the flagship handset will be offered for $149.99, some $50 lower than some of the bigger players. The deal, as you might expect, does require a two-year service agreement and only lasts through the end of the month. Like other wireless providers, CREDO will toss in some bill credits good for up to $350 per line (up to five lines) for those who break a contract. Because CREDO piggybacks off of Sprint’s network, this version of the Samsung Galaxy S5 is tri-band 4G LTE ready.
