Unlimited 4G FaceTime
Since T-Mobile has now switched over to a prepaid, no-contract model, anyone who has an unlimited plan ($70 per month for individuals) will be able to use the iPhone 5's FaceTime calling feature over both 4G LTE and HSPA+ networks, with no data cap.
Its backup network is HSPA+ 42
If you get bumped out of T-Mobile's 4G LTE network range, you'll fall onto its very fast HSPA+ 42 network, with a theoretical speed of up to 42Mbps down. That's a very quick network in its own right, which should help keep future T-Mobile customers happy after the network begins to roll out LTE in earnest.
T-Mobile's iPhone 5 supports HD Voice, which uses hardware and software components on both the phone and on the network to reduce background noise and amp up call quality.
More specifically, it uses a wide-band adaptive multirate codec, which gives you more frequency to handle the amount of audio coming in.
No Wi-Fi calling at launch
How is the iPhone 5 different from all other T-Mobile phones? It won't initially offer Wi-Fi calling, a key T-Mobile feature that lets you make calls for free over broadband.
T-Mobile's chief marketing officer Mike Sievert said that Wi-Fi calling isn't going to be available at the start, but hinted that it could arrive later. T-Mobile has declined to comment beyond that.
