Smartwatch plan cost at T-Mobile, Verizon and AT&T: $10, $15 and $10.99 a month, and T-Mobile's up-to-$3 watch plan increase

As of October 17, 2026, a smartwatch line costs $10 a month on T-Mobile's Watch Plan 2.0 ($15 for Watch Plan Plus 2.0, both with AutoPay), $15 a month on Verizon's Unlimited for Apple & Android watches ($7.50 with a qualifying phone plan), and $10.99 a month on AT&T's wearables plans. Each carrier's monthly per-line fees, taxes and a one-time activation charge come on top. T-Mobile also raised some older watch plans by up to $3 a line in July 2026.

Figures above were read from T-Mobile's smartwatch plans, cell phone plans, support and plan update pages, Verizon's smartwatch plans and Important Plan Information pages, and AT&T's Unlimited plans terms, wearables page and Mobility Fee Schedule on 2026-10-17. See sources.

Smartwatch plan prices side by side

T-Mobile: $10 or $15 with AutoPay, $5 on Experience Beyond 2.0

T-Mobile's smartwatch page lists Watch plan 2.0 at $10 a month and Watch Plan Plus 2.0 at $15 a month, both with unlimited talk, text and high-speed data. Both prices are AutoPay prices, and the terms say: "AutoPay discount requires bank account or debit card, otherwise $5 more/line/mo." That makes $15 and $20 without AutoPay (our arithmetic). Both plans are postpaid only and labeled limited-time.

Watch Plan Plus 2.0 adds travel data: up to 5GB of high-speed data in 215+ countries and destinations, then speeds of up to 256 Kbps. For Canada and Mexico the same page gives two figures. The plan card says "Canada and Mexico: Up to 15GB of high-speed data", while the plan's terms say: "In Canada/Mexico, up to 5GB of high-speed data, then unlimited at max 128Kbps speeds." The page also says customers using more than 50GB a month may notice reduced speeds during congestion.

On T-Mobile's top plan the price is lower. The Experience Beyond 2.0 plan card lists "Watch & tablet lines just $5/month", and its footnote says: "$5/month. price via monthly bill credit while you maintain a qualifying Experience Beyond 2.0." T-Mobile's 5-Year Price Guarantee also covers the price of data on wearable, tablet and mobile internet lines added to an Experience plan, but not taxes and fees.

A watch without a phone line costs more. The general terms on the same page say: "Up to $50 more per line/mo. without qualifying voice line."

T-Mobile's July 2026 watch plan change

T-Mobile retired some older plans in 2026. Its watch and tablet update page is for customers who received a text on June 29, 2026, and says: "The rate of your watch and/or tablet plan will increase by up to $3/line per month." It continues: "Your updated bill will be available in the T-Life app after July 13th." T-Mobile says the new plan comes with 2GB of high-speed data, which it calls 4x more than the old plan, and its 5-Year Price Guarantee. It also says some customers see no change. The full list of T-Mobile's 2026 changes is on our T-Mobile price increase 2026 page.

Verizon: $15 or $25, half price with a qualifying phone plan

Verizon's smartwatch plans page lists Unlimited Plus for Apple & Android watches at $25 a month without a discount and $12.50 with it, and Unlimited for Apple & Android watches at $15 and $7.50. The 50% discount requires a smartphone line on Unlimited Plus, Unlimited Ultimate, Get More Unlimited, Do More Unlimited or One Unlimited for iPhone. Unlimited Ultimate gets the discount on two eligible connected device plans; other qualifying phone plans get it on one. "Discount applied to the highest priced eligible plan on account."

Verizon's watch plans have no Auto Pay discount. The Important Plan Information page says: "Smartwatch plans are not eligible for any discount for enrollment in Auto Pay and paper-free billing."

The Number Share and Number Share Plus plans, which let the watch use your phone number, have the same service and price as the Unlimited and Unlimited Plus watch plans, according to Verizon, plus roaming in Canada and Mexico. The plan information page says watch plans have no international roaming except Number Share in Canada and Mexico, where data slows to 3G speeds after the first 2 GB a day.

Verizon smartwatch plan for kids

Verizon lists Unlimited for Gizmo & CareSmart watches at $10 per line per month. "Gizmo and CareSmart plans are not eligible for discount." Verizon Prepaid separately lists a smartwatch plan at $10 per line per month with 15 GB of high-speed data, plus taxes and fees.

AT&T: $10.99, discounted on Premium 2.0 and Elite 2.0

AT&T's Unlimited plan terms set the Apple Wearables Plan and the Android Wearables Plan at $10.99 a month each, and list "$10.99 per wearable" as the standard non-phone device charge on AT&T Value 2.0 and Extra 2.0. A phone line is required: "If no phone line, first standalone non-phone device will be billed at $75.99."

Two phone plans reduce the watch price:

• AT&T Premium 2.0: 50% off the standard monthly charge for one associated tablet plan or smartwatch wearable plan per line.
• AT&T Elite 2.0: 100% off the standard monthly charge for one associated tablet plan and one smartwatch wearable plan per line, "although the customer is responsible for any applicable taxes and fees associated with the standard monthly service charge for these plans".

AT&T's AutoPay and paperless discount is written per phone line ($10 a month with a bank account or the AT&T Points Plus Card, $5 with a debit card). On travel, the Apple Wearables Plan lets Series 5 and later watches use data in Mexico and Canada, the Android Wearables Plan covers the U.S. only, and AT&T's International Day Pass is not available for wearables. Day pass prices are compared on our international day pass page.

Do per-line fees apply to watch lines?

Each carrier charges a flat monthly fee per line. Only AT&T's watch plan terms name the fee directly; T-Mobile and Verizon list separate amounts for voice and data lines without saying which one a watch line pays.

• T-Mobile lists two rates on its support page: $5.49 per voice line and "Mobile Internet lines: $2.60 per line every month (Regulatory Programs $0.12; Telco Recovery $2.48)." The smartwatch plan terms say "Regulatory Programs & Telco Recovery Fees totaling up to $5.49 per line", and the page's general terms name the $0.50 and $4.99 voice-line amounts "unless you already have a tax-inclusive voice line". T-Mobile's plan labels add that the fees "may not apply to certain data devices/services".
• Verizon lists its Administrative and Telco Recovery Charge at $3.78 per voice line, rising to $4.69 on November 15, 2026, and "$3.97 per data-only line". Its Regulatory Charge is $0.21 per voice line (rising to $0.26 on November 1, 2026) and $0.02 per data-only line. Verizon says the Administrative and Telco Recovery Charge is applied to each line on the account.
• AT&T lists its Administrative & Regulatory Cost Recovery Fee at $4.99 per line per month. Its wearables plan terms say monthly AT&T fees apply per line and include that fee (up to $4.99). The fee schedule does not give a separate amount by device type.

The amounts for phone lines and their 2026 changes are on our carrier fees per line page.

Activation charge for a watch

T-Mobile's watch plan terms say "$35 device connection charge due at sale." Verizon's Important Plan Information page lists an Activation/Upgrade Fee of $40 per line and says: "Activation/Upgrade fees waived for customers enrolled in Verizon Loyalty program." AT&T's Mobility Fee Schedule lists $35 ($50 for subsidized devices sold with a service commitment), and its wearables plan terms say an activation or upgrade fee of up to $50 may apply. More detail is on our activation fee page.

What we could not confirm

• Which T-Mobile fee amount, $5.49 or $2.60, appears on a watch line. The smartwatch page, the support page and the plan label give the amounts above without naming watches in either category.
• Whether Verizon bills a Number Share watch as a voice line or a data-only line for its surcharges. The smartwatch page and the Important Plan Information page do not say.
• T-Mobile's Canada and Mexico data on Watch Plan Plus 2.0: the plan card says up to 15GB and the plan terms say up to 5GB.
• The data allowance on a $5 Experience Beyond 2.0 watch line. The plan page gives the price, not the watch plan it applies to.
• Current monthly line prices for T-Mobile's SyncUP KIDS Watch and AT&T's amiGO Jr. Watch. The device pages we read show device prices and offers, not a current plan price.
• Verizon's standalone price for a watch on an account with no phone line. Its smartwatch page says the standalone plan price applies but does not list it.
