Apple Watch cellular plans cost between $10 and $20 per month as an add-on to an existing smartphone plan at major U.S. carriers. A cellular plan lets the Apple Watch make calls, send messages, and stream music independently of the iPhone, but the watch requires a supported carrier plan and must use the same carrier as the iPhone.
What Apple Watch cellular plans cost and how they work
Adding a cellular plan to an Apple Watch turns it into a standalone device for calls, texts, and data when the iPhone is not nearby. The cost is an add-on fee to your existing phone plan, and both devices must be on the same carrier. Setup is handled through the iPhone’s Watch app, not directly on the watch.
Requirements before you set up cellular
Apple requires two conditions for cellular setup: the iPhone and Apple Watch must use the same carrier, and the setup must be completed while the watch is within that carrier’s network coverage. The standard setup path is to open the Watch app on the iPhone, tap My Watch, then Cellular, and follow the onscreen instructions. During setup you may also tap Set Up Cellular.
Apple Watch cellular plans at Verizon
Verizon offers smartwatch plans for eligible Apple Watch models through its Number Share feature, which allows talk, text, and data sharing between the iPhone and watch. The plan is added to an existing Unlimited or Unlimited Plus smartphone plan. A standalone plan option with a separate phone number for the watch is also available. An activation fee may apply when first activating Apple Watch with Verizon. Setup begins with an eSIM profile download to connect the watch to the Verizon network. For readers comparing Verizon and prepaid plan options, note that Verizon’s documented smartwatch plans are postpaid and tied to its Unlimited or Unlimited Plus tiers.
Apple Watch cellular plans at AT&T
AT&T uses NumberSync for Compatible Apple Watch (GPS + Cellular) to sync the watch with the user’s iPhone number. A single device plan starts at $10/month with unlimited talk and text. Multi-device plans start at $20/month for adding a watch to an existing plan with shared data. An unlimited plan for Apple Watch is available at $60/month. After setup, the watch can talk, text, and use cellular data on AT&T’s domestic network in the U.S., Puerto Rico, and the U.S. Virgin Islands. The watch must complete NumberSync setup to access the AT&T cellular network.
Apple Watch cellular plans at T-Mobile
Before setting up cellular on T-Mobile, Bluetooth must be on and the iPhone must be connected to Wi‑Fi or cellular. The setup follows Apple’s standard path through the Watch app: Watch app > My Watch > Cellular > Set Up Cellular. The DIGITS plan starts at $10/month and the One Plus plan starts at $15/month. The One Plus plan includes international roaming, faster data speeds, and unlimited 4G LTE mobile hotspot. T-Mobile’s support documentation does not specify a different menu path or model list beyond Apple’s general instructions.
Finding plans at other carriers
Carrier support for Apple Watch cellular varies by region. Apple’s official cellular page shows Verizon, AT&T, and T-Mobile among supported U.S. carriers, but availability depends on your location. Other carriers offering Apple Watch cellular plans include Sprint, US Cellular, Cricket Wireless, Metro by T-Mobile, and Boost Mobile. To find plans at other carriers, check Apple’s cellular page for a current list of supported carriers in your area.
