Verizon had the launch exclusive but the HTC One M8 with Windows Phone will be available on other U.S. carrier networks. On Thursday, T-Mobile announced the phone will arrive in time for the holidays and has created a sign-up page for interested customers. The news follows AT&T’s announcement last week that it too will sell the handset. Sprint hasn’t said if it will carry the phone as of this time. Regardless, this is all good news for both Microsoft and HTC as both are struggling in the mobile market. The HTC One M8 is an excellent piece of hardware that runs the much improved Windows Phone 8.1 software; more carrier availability could boost sales.
