How to Buy an iPhone Online

For most of these models, you can buy used or refurbished ones on auction sites and retail sites. The price you pay depends on the condition of the phone. Unless the phone is designed for a carrier that you plan to use, you will want an unlocked cellphone.

Another option is to buy one directly from the Apple site. However, not all phones are available through the site, and you may have to visit an authorized cellphone dealer to buy a new one. Alternately, you may find a newer model that is used or refurbished from an online retailer. If you purchase from a non-authorized dealer, it may be helpful to buy from a company that offers some form of warranty. Authorized dealers usually include cellular service companies. They may offer you monthly payment plans if you have decent credit and either sign up for new service or upgrade your current phone.
