Wi-Fi calling comes to T-Mobile HTC Amaze 4G, Galaxy S II

On Monday, T-Mobile quietly rolled out a software update for its HTC Amaze 4G that, most notably, introduced the ability to make Wi-Fi calls. An official update today also added that feature and more to the carrier's Samsung Galaxy S II smartphone.

Wi-Fi calling sets T-Mobile apart from other carriers, but until now, it was only available on select phones. In fact, it was one of the five best features we discussed when an AT&T/T-Mobile merger seemed imminent. Given T-Mobile’s admittedly limited cellular network, the Wi-Fi calling option makes for a great fall back when signal is hard to come by. T-Mobile customers using phones like the myTouch 4G have already been enjoying this feature, and T-Mobile seems determined to bring it to as many phones as it can.

The added capability comes in the form of a device upgrade to Android 2.3.5, which T-Mobile claims will also improve the performance of the Samsung Galaxy S II. The update addresses a number of issues, including a "Force close" problem that dropped calls when split in a conference call. Also rolled into the update are improvements to Caller ID and battery notifications. T-Mobile notes that customers must have a GBA SIM card to access the added Wi-Fi calling capability, but most phones should already be equipped with the right card.

 

The new software update will bring greater functionality to already great phones. PCMag gave the Samsung Galaxy S II and the HTC Amaze 4G high marks, with the former garnering our Editors' Choice for T-Mobile smartphones. Both boast solid HSPA+ 42 speeds and beautiful displays, making them excellent choices for T-Mobile customers. Though coverage may be limited, T-Mobile did score second fastest in our mobile network test earlier this year.

The update will be available through an over-the-air download and through Kies Mini, beginning Dec. 14.
