MobiGater is a new possibly groundbreaking device that enables you to make Skype calls on your mobile phone without installing any software on your phone.

MobiGater is a Skype to GSM Gateway that connects via USB to a PC to connect to the Skype VOIP infrastructure.
You need to get a SIM card for the MobiGater to make it work. Bulgarian based EURO DESIGN Ltd., the maker of the MobiGater recommends to get a SIM card with low rates on the same network as your mobile phone.
When making calls via Skype you still have to pay for the call to the MobiGater device.

If you make a lot of international calls the MobiGater can save you a bundle here.

The elegant aspect of this solution is that you can use your mobile phone anywhere and make cheap Skype calls. If you have a Symbian S60 2nd edition phone you can also run the Mobiskype software that shows you your Skype buddy list.

The MobiGater comes in a personal use and a profession office version that also features a remote web configuration option. The MobiGater Plus sells for 199 Euro (~$260) and the MobiGater Pro for 299 Euro (~#391).
