Apple's iPhone Handoff feature is designed for people who want to use two compatible iPhones without juggling separate phone numbers. But there is an important cost to consider: Verizon has announced a $10 monthly charge for the feature.

For shoppers considering the iPhone Duo alongside an iPhone 18 Pro, the extra subscription could influence the total cost of owning two phones.

What is iPhone Handoff?

iPhone Handoff allows a supported phone number to be used across two compatible iPhones. Instead of manually moving the number between devices, users can designate a primary and a companion phone and switch which device is active.

This can be useful for someone who wants a foldable iPhone for travel and a conventional iPhone for other situations. It may also appeal to people who prefer different devices for different routines, provided their account and devices meet the feature's requirements.

However, Handoff should not be confused with having two independent phone lines. The feature is designed around sharing one number, and the number is active on one iPhone at a time.

How much does Verizon charge?

Verizon has announced a $10-per-month fee for iPhone Handoff on compatible iPhones running the required software. That adds $120 over 12 months, before any applicable taxes or other charges.

The fee is separate from the purchase price of the second iPhone. Anyone budgeting for an iPhone Duo and an iPhone 18 Pro should calculate the hardware cost, wireless plan, accessories and Handoff fee together.

Who might benefit from Handoff?

• Two-device users: People who want a foldable iPhone and a traditional iPhone while keeping one number.
• Frequent travellers: Users who prefer a different phone for particular trips or situations.
• Apple enthusiasts: People who enjoy using more than one compatible iPhone and want to reduce the inconvenience of switching devices.

It may be less valuable if you usually carry just one phone, rarely switch devices or can meet your needs by transferring an eSIM when necessary. Availability can also depend on carrier support, device compatibility and account restrictions.

Is the extra $10 worth paying?

The answer depends on how often you will use the feature. If two iPhones are part of your everyday routine, the convenience may justify the fee. If the second device is mostly a backup, a recurring charge may be harder to justify.

Before activating Handoff, check Verizon's latest eligibility requirements, supported models, activation steps and any account limitations. Do not assume that every plan or business account supports the feature.

Final verdict

iPhone Handoff makes owning two compatible iPhones more convenient, but Verizon's $10 monthly charge turns that convenience into an ongoing expense. Work out the annual cost before buying a second device, and compare it with the alternatives available on your plan.

Would you pay $10 every month to share one number across two iPhones, or would you rather switch devices manually? Tell us what you think.
