Thank you for reaching out to us. It's important to know if you can use an iPhone 4 with or without a data plan and I'll be happy to help. Please be aware, all of our smartphones do require a data plan. Ann154 gave some great information about trying to activate an iPhone 4. Can you tell me more about why you're inquiring about activating an iPhone 4? Are you a current customer and if so, can you tell me if you're explaining any issues with your current phone?
