Users of unlocked iPhones on T-Mobile's network will soon be able to take advantage of LTE and Visual Voicemail. These features had been previously disabled because they did not come with network support. Now that T-Mobile is getting the iPhone, they are able to push out OTA updates to all iPhones running on the network.
The T-Mobile Carrier Update is a minor iOS software update that enables official iPhone support by T-Mobile. When installed, the software update enables a handful of capabilities like Visual Voicemail, MMS Settings and Network/Device optimizations that customers do not have access to today.
On April 5, the software update will begin being pushed via OTA to all iPhone devices on the T-Mobile network with iOS 6.1.x or higher.
The update comes one week before the iPhone is officially released to T-Mobile customers. T-Mobile has long allowed unlocked iPhones to be used with their network, though the users had to deal with slower networks due to network compatibility issues. If you're a current T-Mobile customer with an unlocked iPhone, let us know which feature you're most looking forward to.
