The new "MagSafe" iPhone 12, 13, 14, and 15 need the iCell Chip where as smart phones before that generation need the Cell Chip.

If you want to talk about priority, it is smartest and safest to get the overall structure of your home remediated but if that is not financially possible for you and your family at this time, we recommend personal protection chips (4-6 per person) as well as getting your personal devices protected (Laptops and Cell Phones).

It varies from situation to situation. Some people live in more remote areas and some live in apartments. It also depends on the amount of devices you have in your home. If you fill out our customized questionnaire I give you custom pricing based on your specific situation.
