3. Scroll down and tap on "choose this plan" next to the plan you wish to proceed with.  
4. On the next page, tap on "continue" and follow the steps to complete the order. A card verification will be required. After completing this step, tap on "place order".  
5. You will receive an order reference number at the end.
