An insurance product that covers repair or replacement costs for smartphone screen cracks, water damage, malfunctions, and theft. Multiple options exist including carrier protection services, manufacturer warranty plans, and dedicated insurance from small-amount short-term insurance companies, with enrollment rates rising as device prices continue to climb.
Types of Smartphone Insurance and Coverage Comparison
Smartphone insurance comes in four main forms. First, carrier protection services (docomo, au, SoftBank) cover screen cracks, water damage, and total loss for roughly 300 to 1,000 yen per month. Second, manufacturer warranty plans like Apple Care+ and Samsung Care+ cover accidental damage in addition to natural malfunctions. Third, dedicated insurance from small-amount short-term insurance companies such as justInCase and Mobile Insurance, which accept enrollment regardless of carrier. Fourth, credit card-bundled smartphone insurance that automatically applies when you pay your phone bill with the card.
When comparing coverage, the deductible (out-of-pocket amount) is a key decision factor. Apple Care+ sets deductibles at 3,700 yen for screen repairs and 12,900 yen for other repairs. Carrier protection services charge 2,200 to 12,100 yen per replacement. Some small-amount short-term insurance plans have zero deductibles, though monthly premiums tend to be slightly higher. Choose based on your device price and usage style (likelihood of drops).
Deciding Whether to Enroll and Evaluating Cost-Effectiveness
Whether to enroll in smartphone insurance depends on the balance between device price and repair costs. An iPhone 15 Pro Max screen repair costs 56,800 yen at an Apple authorized service provider, and rear glass repair costs 25,900 yen. If total insurance premiums over two years amount to 24,000 yen, a single screen crack during that period makes the insurance pay for itself. On the other hand, for mid-range devices under 50,000 yen, the gap between repair costs and premiums is small, reducing the benefit of enrollment.
As an alternative to insurance, equipping a shock-resistant case and tempered glass screen protector is an option. An investment of 3,000 to 5,000 yen can significantly reduce the risk of screen cracks, offering high cost-effectiveness. Another rational choice is to reduce device costs by purchasing used or SIM-free devices and simply replacing the phone if it breaks. Insurance is essentially "peace-of-mind money against expensive repair bills" - decide based on your own risk tolerance.
