Yes, it is possible. The device is compatible and can connect to the local 3G network (Turkcell) with minimal hassle. In addition, even though I had to purchase a two-year T-mobile subscription with my phone, the device is unlocked! Disclaimer: I purchased this phone directly from Google in May 2010. Google is no longer doing this. As soon as I landed in Istanbul, I went to the Turkcell kiosk, registered my IMEI number, purchased a prepaid card, and activated it. You MUST register your phone with the government agency or it may be banned permanently. The next step is to subscribe to the 3G internet service. There are two types of 3G services: 1. Faturali (invoiced) 3G Internet http://www.turkcell.com.tr/bireysel/3G/3Ginternet/tarifeler/faturali3Ginternet Subscription for this plan is automatically renewed every month. And there is an overuse charge which is currently 0,050 TL/MB. 2. Faturasiz (non-invoiced) 3G Internet http://www.turkcell.com.tr/bireysel/3G/3Ginternet/t...
