iPhone® 3GS - what’s in the box?
iPhone 3GS pay as you go on O2 network includes 12 months unlimited 3G data and Wi-Fi.
In contrast with an iPhone 3GS pay as you go on Orange network, Internet access is capped to 250MB per-month 3G data. Unlimited Wi-Fi allows an alternative Internet connection via hotspots. The main advantage of Orange iPhone 3GS is perhaps the most important aspect overlooked – better network coverage. After all a phone is no use without a signal.
