You can get a WiFi module for your arduino, but it is cheaper to get a Bluetooth module such as an HC-05 with carrier card to make connection easy. This could be controlled from a smart phone or a PC.

Dropping connection can be annoying....But I like the idea of getting control with a smart phone! Xbee worked perfect for me inside the house, but it also dropped the connection outside, so I guess you would have to include a connection recovery in your design with either technology ....

I use an HC-05 which is Bluetooth class 2 (30 meters) connected to my Galaxy Note and it works well throughout my 2-story house, including through walls. If you want better range you can get a Bluetooth class 1 device (100 m).
