T-Mobile iPhone 5 Possible with Nano SIM in October Adam Mills09/14/2012 A leaked document indicates that T-Mobile is preparing to offer Nano SIM cards for use with Apple’s new iPhone 5, a device which employs a Nano SIM slot. TMoNews unearthed a document that appears to show the carrier’s plans to offer the Nano SIM card sometime in mid-October. No device in T-Mobile’s lineup uses a Nano SIM card and no other phone in the U.S. uses Nano SIM so it’s clear that this is going to be aimed squarely at T-Mobile users who wish to bring the iPhone 5 to T-Mobile’s network.Advertisement Those who want to get a T-Mobile iPhone 5 up and running in October on T-Mobile’s network will have some options. One of those options is to order an unlocked iPhone 5 which comes with a steep price tag and an unknown release date. Read: No T-Mobile iPhone 5, But Hope Isn’t Lost. Those looking to get a Nano SIM for the iPhone 5 will be able to get one through T-Mobile in October.Advertisement Apple will sell the unlocked iPhone 5 for $649.99. And that’s for the 16GB model. The models with more storage space will check in with much steeper price tags. An unlocked 32GB iPhone 5 model is $749.99 while the 64GB iPhone 5 will cost $849.99.Advertisement That’s a pretty steep cost but for those that are willing to pay it, T-Mobile’s network awaits. Of course, we don’t know exactly when the unlocked iPhone 5 will be released in the United States. Verizon told us that it will have the unlocked iPhone 5 available on release day, but we’re still unsure if that’s true considering Apple said it wouldn’t launch until a few weeks after September 21st.

As we pointed out yesterday, the network bands that Apple launched with the new iPhone 5 match up perfectly with the ones that T-Mobile is planning for its new 3G and 4G networks.Advertisement T-Mobile already began shifting its HSPA+ network to 1900 MHz and the carrier says there will be a much larger footprint by the end of the year. In addition, the AWS spectrum that is supported by the iPhone 5 is the same spectrum that T-Mobile will use with its 4G LTE network next year. Those line up exactly with AT&T’s network making an AT&T iPhone 5 an option as well. Anyone going to buy a Nano SIM for use with a T-Mobile iPhone 5?
