You can purchase an AT&T mobile plan and phone from the company's website, which has a good selection of smart phones, tablets and other mobile devices. In addition, you can choose from AT&T's catalog of voice and data plans, including pre-paid and international plans as well as phone accessories.
Online catalog items display device cost, installment options (if applicable), customer reviews and a feature that allows you to check in-store availability by typing in the relevant ZIP code. As the online price and store price of an object may vary, it may be worth your time to compare the two.
When a phone is chosen, you simply click on the "Add to Cart" button. If you already have an AT&T account, you need to log in first before completing the order, whereas if you are new customer, you need to create a personal account. In a similar manner, you can shop and add voice and data plans and phone accessories to your account cart. The website has a live chat feature for extra help in online ordering.
For some orders, you have the option to either having the item shipped to a nearby AT&T store for pickup, or have it delivered to your home or office address.
