Update enables Visual Voicemail, LTE network connectivity
Reportedly, T-Mobile is planning on sending carrier updates to unlocked iPhones used on its network on or around April 5. The update should enable LTE and Visual Voicemail to the devices brought to the carrier. The update will be pushed only to iPhones running iOS 6.1 or greater.
The internal notice obtained by TMONews says that 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 [Over-the-Air] to all iPhone devices on the T-Mobile network."
One week later, T-Mobile will start carrying its own "uncarrier" version of a subsidized phone. For an up-front cost of $100 and $20 per month for two years, users can purchase the iPhone 5. The iPhone 4 and iPhone 4S will also be available in select markets --though without LTE access -- at a cost of $15 down and $15 per month for 24 months for the former, and $70 down and $20 per month over the same period for the latter.
T-Mobile's LTE network is currently running in seven cities: Baltimore, Houston, Kansas City, Las Vegas, Phoenix, San Jose and Washington D.C. More cities are promised by the end of the year.
The new Simple Choice plans offer unlimited calls and texts on all plans, with data driving the price differences. A 500MB plan will cost $50 per month, while the 2GB option will cost $60. Data allowances including tethering, with data speed constrained down to 3G once the cap is used up. Another option, offering unlimited national 4G coverage for $70, will include an extendable 500MB limit for tethering.
