Review: Sanyo MM-5600
The MM 5600 is among Sprint's new handsets that has mobile originating SMS. This means you can compose and send text messages right on the phone without logging on to Sprint's WAP site. Tapping up on the D-Pad opens the messaging app, after which Send Message is the first option. Then, like on Sony Ericsson phones, you choose the type of message.
The 5600 asks to address the message before composing the text. You can choose a number from your phone book, recently messaged numbers or manual entry. Once this is complete you'd expect to proceed to a text entry window, but after you hit Next, you're taken to an odd screen to edit a number of options, including the message text if you click in the blank field.
The MM 5600 uses T9 for its predictive text, and it is very fast on the phone. The dictionary is already populated with common text and IM abbreviations, further speeding up typing in a message.
Receiving messages works as it should with alerts and a dialog box on the home screen. All messages, even voicemail alerts are displayed like emails from the late '80s (remember Pine?) with lots of text description and dash line dividers as opposed to the more standard modern email type displays common in most phones.
