The various ways to get free mobile themes, or wallpapers, include searching online for websites that offer theme downloads at no charge and contacting your cellphone service provider to see what it has to offer. The provider may have free options, depending on your service agreement.
Another more personal way of getting free themes for your phone is to create them yourself. You can do that by choosing from among your favorite photographs, for example, and downloading them to your device. There are also online companies that allow you to select free themes from their stock selections and customize them.
