T-Mobile USA, the No. 4 U.S. mobile phone service, said yesterday it is offering a $50 per month service plan to long-time customers in San Francisco.
Under the promotion the company is also offering customers a $135 credit if they switch from a rival service to T-Mobile USA.
The test promotion comes after Boost Mobile launched an all-in mobile plan for $50 a month in January. T-Mobile USA is seen by analysts as the carrier most vulnerable to losing customers to Boost.
A T-Mobile USA representative said the plan would only be available to customers who have used its service for 22 months or more and that as the company has “additional details regarding a national plan it would provide” them.
UBS analyst John Hodulik said in a research note that he expects the plan to be available nationwide in coming weeks.
With 85% + consumer penetration here in the US, it makes sense that the price wars would start to heat up. This can only be good for US consumers who need all the help they can get reducing their monthly expenses.
