Identification Differences
Two of the four iPhone 6 models can be uniquely identified by Model Number, which is listed on the back of each device in tiny type. The other two iPhone 6 models are a bit more complicated to pinpoint.
Nevertheless, the four different iPhone 6 models have these model numbers:
iPhone |
Model Number |
As noted above, two of the iPhone 6 models -- both distributed in the United States -- are the challenging ones to identify as they share the A1549 model number.
Consequently, if the A1549 iPhone 6 will boot, the most convenient way to uniquely identify it is with the Order Number -- which Apple refers to as the "Model" within the iOS -- or by its Serial Number listed in software.
To find the "Model" and Serial Number, touch the "Settings" icon on the homescreen and select General > About and then scroll until "Model" or "Serial Number" is visible. The "Model" identifier looks like MG5W2LL/A, which specifically refers to the Verizon A1549 iPhone 6 in gray with 16 GB of storage.
Once you have located the "Model" or the device serial number, EveryiPhone.com's Ultimate iLookup feature -- as well as the EveryMac app for iOS 5 or later, Android, and Kindle Fire -- can identify it precisely.
Network Connectivity & Carrier Support Differences
Each iPhone 6 model supports 802.11a/b/g/n/ac, and specifically 802.11ac with speeds up to 433 Mbps, as well as Bluetooth 4.0 and GSM/EDGE (850, 900, 1800, 1900 MHz).
All other connectivity varies by model:
| iPhone Model | Model No. |
UMTS/HSPA+ DC-HSDPA |
CDMA EV-DO |
TD-SCDMA | LTE Bands (4G) |
| 6 (GSM/North America) | A1549 | 850, 900, 1700/2100, 1900, 2100 MHz | None | None | 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29 |
| 6 (CDMA/Verizon) | A1549 | 850, 900, 1700/2100, 1900, 2100 MHz | 800, 1700/2100, 1900, 2100 MHz | None | 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29 |
| 6 (Global/Sprint) | A1586 | 850, 900, 1700/2100, 1900, 2100 MHz | 800, 1700/2100, 1900, 2100 MHz | 1900 (F), 2000 (A) | FDD-LTE (1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29); TD-LTE (38, 39, 40, 41) |
| 6 (China Mobile) | A1589 | 850, 900, 1700/2100, 1900, 2100 MHz | None | 1900 (F), 2000 (A) | FDD-LTE (1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29); TD-LTE (38, 39, 40, 41)† |
In the US, the GSM version of the A1549 iPhone 6 is sold unlocked and without a contract on T-Mobile and it does not support CDMA networks. Apple refers to this model as the "T-Mobile" iPhone 6. Starting on January 6, 2015, Apple also started selling an unlocked version of the A1586 "Global" iPhone 6 in the US, which Apple refers to as the "Unlocked" iPhone 6. Although Apple makes no mention of it, and it is bound by a two-year contract, the iPhone 6 is offered unlocked on Verizon, too.
The China Mobile version of the iPhone 6 supports the WCDMA variant of the UMTS standard on the same frequencies as the other models and the same FDD-LTE and TD-LTE bands as the "global" devices, but UMTS and FDD-LTE formally are "only for international roaming" rather than for use within mainland China.
For complete details regarding LTE support, it will be necessary to check with specific carrier(s) in a particular location.
