Unlike Samsung’s other Montes, this is far from a complete package.
The slider reference pertains to the fact that the keypad slides out and the handset skips a touch screen altogether. It looks to be a low-end entry into the market for them trying to piggyback on the Monte name.

The E2550 looks like a redesign of one of their other recent phones and has specs similar to another. It’s not a terrible looking package and feature list and there is certain to be a market for the phone now and into the future. Why they would call it a Monte when it’s nothing like other phones with the moniker is beyond us.
