Review: Huawei Prism for T-Mobile
Calls
The Prism makes use of the stock Android 2.3.6 phone application, and Huawei hasn't done anything to dress it up. That's just fine. In-call features run the typical set: send to Bluetooth, speakerphone, mute, merge calls, etc. The Prism does include T-Mobile's Wi-Fi calling feature, which works well when under the wireless umbrella of Wi-Fi.
Contacts
The Prism uses the stock contact application, as well. With access to myriad different contact databases, the Prism lets you carry a virtual white pages in your pocket. Each contact entry lists gobs of details, and makes calling or sending messages a cinch from any contact card. I like that you can easily switch from seeing a contact's information to your history with that contact (calls, emails, IM, SMS, etc.) and even their photos. Searching through the contact database is a breeze with the built-in search tool.
