T-Mobile USA Blames Lack of iPhone for Customer Loss in 4Q 2011
Sequentially, the decline in branded net contract customers was driven primarily by higher branded contract deactivations as a result of the launch of the iPhone 4S by three nationwide competitors in mid-October.Following the collapse of a deal that would have seen T-Mobile USA acquired by AT&T, T-Mobile USA is seeking to reposition itself with a "challenger strategy" and move aggressively to roll out 4G LTE services beginning next year.
Other U.S. carriers have already been rolling out their LTE networks for some time, but T-Mobile has been behind that curve as it has relied on HSPA+ technology that previously gave it an advantage over some of the other carriers in data speeds. But with AT&T having upgraded its own network to HSPA+ even as it is already building out LTE, T-Mobile is now finding itself scrambling to recover from the holding pattern is was in while the AT&T acquisition deal was pending.
