How can I get my iPhone insured after purchasing it?

AppleCare Products - iPhone

"Every iPhone comes with one year of hardware repair coverage through its limited warranty and up to 90 days of complimentary technical support. Both AppleCare+ and AppleCare+ with Theft and Loss extend that coverage and give you additional features such as 24/7 priority tech support and accidental damage protection."

How to buy

1. Purchase either AppleCare+ product with your new iPhone.
2. Or buy it within 60 days of your iPhone purchase:

• On your device (go to Settings > General > About and choose AppleCare+ Coverage Available)
• Online (requires you to verify your serial number and run a remote diagnostic)
• At an Apple Store (inspection of iPhone and proof of purchase are required)
• By calling 800-275-2273 (requires you to run a remote diagnostic and provide proof of purchase)

Note: This phone number is from the US Apple website. Check your local Apple website for your area

Unless you purchase Applecare + with theft + loss protection, you are not buying insurance technically. Your device will be covered against mfr's defects and some accidental damage, but it is not considered insurance. You can get that from your home insurance carrier.
