If you live in the UK and have a PAYG SIM card with a ton of free text messages and another with a bunch of free minutes, you will probably of used either the two mobile phones way or keep switching SIM cards each time you want to send a text or make a voice call. I personally havent done this my self as I got fed up after trying for a day and just paid a larger bill instead. The Wind DUO 2000 comes in answer to this. It has 2 screens, 2 keypads, and 2 SIM card slots. It allows you to use 2 phones together on one device so you can have the convenience right there with out the hassle of switching off and on and changing SIM cards.
Overall it does look like a fairly good option for those wanting to use 2 SIM cards and have access to both at the same time with out the hassle of switching them. It isnt a phone that I need personally as I only use 1 SIM card, but I do know a ton of people who could use something like this.
