T-Mobile USA: Understanding network compatibility of an unlocked iPhone 5
Any GSM iPhone 5 model A1428 will support T-Mobile's LTE network and HSPA+ speeds of up to 21 Mbps. To experience DC-HSDPA up to 42 Mbps on T-Mobile, you need an iPhone 5 GSM model that supports T-Mobile's AWS band (1700/2100).
To find out if your iPhone 5 supports AWS band (1700/2100), follow these steps:
- Identify your iPhone model number. You need to have iPhone 5 model number A1428.
- Tap Settings > General > About and check if your serial number ends with any of these four-digit combinations:
Note: You can also locate your iPhone 5 box and verify that the label includes "1700/2100" under the UMTS/HSPA+/DC-HSDPA bands.
If your iPhone meets both of the above criteria, then it supports AWS band (1700/2100). When using a T-Mobile SIM card, you will be able to access T-Mobile DC-HSDPA speeds up to 42 Mbps (depending on availability).
Any iPhone 5 model A1428 includes full support of T-Mobile's LTE bands at the same speeds if it is unlocked. iPhone 5 model A1429 does not support T-Mobile's LTE bands.
- Starting with T-Mobile availability, you can purchase iPhone 5 models that support AWS band (1700/2100).
- If you have one of the iPhone 5 models that supports AWS band (1700/2100) and are experiencing any cellular-connectivity issues, see this article.
