The fact that the phone is still under contract shouldn't matter in terms of taking it to AT&T.
This is important, because not only must the wireless technology be the same in order to have device interoperability among different wireless operators, but the spectrum frequencies and the so-called band plans used to define those spectrum frequencies in devices need to be the same too.In the early days of LTE deployments, the frequencies used by US operators were all different.
While upgrading coverage inside the West side of the Moscone Center, T-Mobile has also deployed 4G HSPA+ service in the 1900 MHz band to test the live network on a small scale. While T-Mobile insists this is just a coincidence, the timing seems almost too convenient, suggesting that the carrier is attempting to show off their iPhone-compatible service to the exact audience they hope will eventually become their customers.

But as I will explain later, this is only the case because you're taking a 4G LTE device from Verizon to another carrier. Verizon had a nationwide license for 700MHz spectrum that only it had access to, and the band class used in its LTE devices was used only by Verizon.
But if you look at the chart above, you'll see that some of the supported frequencies and band classes overlap. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Import charges previously quoted are subject to change if you increase you maximum bid amount. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. That's a question asked by one Ask Maggie reader confused by the puzzling state of device interoperability. As Verizon and other wireless operators expand their networks, they're starting to use common slivers of wireless frequency to deploy their service.

I'm sure you realize that for years most cell phones weren't interoperable among all the US carriers. There's always been a big divide between AT&T and T-Mobile devices, which for the most part have always been interoperable, and devices from Verizon Wireless and Sprint.
While iPhones from AT&T and T-Mobile could operate on Verizon's LTE network because the devices all include support for LTE bands 4 and 13, which are used by Verizon for its LTE service, they don't support CDMA at all.
This technology is used throughout much of the world and relies on SIM cards, which can be swapped in and out of unlocked devices to provision service. So wireless customers wouldn't be able to access Verizon's voice or 3G data network.This table offers information regarding the 4G spectrum frequencies and LTE bands supported by the four major US wireless operators. So for the most part, even though Verizon and Sprint devices use the same technology and often use the same spectrum, they can't be used on each other's networks.In the era of next-generation 4G wireless networks, all the major mobile carriers throughout the world, including the four major operators in the US, are finally using the same technology, known as LTE.
But unlike with the older GSM and CDMA technologies used to deliver 2G and 3G services, carriers have been deploying this new technology using different wireless spectrum frequencies.
