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).
T-Mobile just announced the iPhone 5 for their USA network. It is scheduled to be released on Friday April 12th. This new Model A1428 will be the same as the current model A1428 iPhone 5 with one difference. It will enable the AWS 1700/2100 band.
To check and see if your iPhone 5 supports AWS band (1700/2100), follow these steps:
- Go to Settings –> General –> About.
- Check the last 4 digits of your serial number to see if they match these combinations:
- You can also locate your iPhone 5 box and verify that the label includes “1700/2100” under the UMTS/HSPA+/DC-HSDPA bands.
