While the iPhone 3G Voice and Data Packages allow you to use this device to its fullest and offer savings over separate voice and data plans, they are not the only options available to you. Other pricing options are available. For example, you may choose to combine one of our new data plans ranging from $30 per month (for 300MB) to $100 per month (for 6GB) with a voice plan. Learn More. They are available by calling 1 888 ROGERS1 or by visiting your nearest Rogers retail location.

$100!!! For 6Gb??? Go fuck yourself Rogers
