If you only chase one internet promotion in 2026, make it the free mobile line. A single unlimited line runs $25–$40 a month, so getting one free for a year is worth roughly $300 to $480 — usually more than any gift card on offer.
The catch is simple and manageable: it's free for 12 months, then bills at the standard rate. Handle that one date and you've pocketed real money. This guide compares the providers that offer it and shows how to lock in the value. It pairs with our broader internet + mobile bundle guide and the complete bundling guide.
Who offers a free mobile line — and how they compare
Two providers anchor this deal in 2026, with others offering mobile-and-internet discounts instead of a free line outright.
| Provider | The deal | Network | Worth knowing |
|---|---|---|---|
| Xfinity | 1 free unlimited line, 12 months, with qualifying internet | Runs on Verizon's network | Often pairs with gift-card/bundle discounts; deep cable footprint |
| Spectrum | 1 free unlimited line, 12 months, with internet | Runs on Verizon's network | Adds up to $500 contract buyout + savings guarantee; no contracts/caps |
| T-Mobile | Discounted home internet (~$35/mo with AutoPay + voice line) — not a free line, but the inverse deal | T-Mobile network | 5-year price guarantee on home internet |
| Verizon | Mobile + Home discount up to $15/mo (not a free line) | Verizon network | Gift cards on select plans |
Offers are illustrative, vary by address, and change frequently. Confirm current terms before signing up.

How to make sure it stays worth it
- Confirm the qualifying internet plan. The free line usually requires a mid-tier internet plan or higher, not always the cheapest one.
- Check network coverage where you live. Both Xfinity and Spectrum mobile use Verizon's network — make sure that's strong at your home and the places you go.
- Note the 12-month date. Set a reminder for month 11. When the free period ends, decide: keep the line at standard rate, cancel it, or renegotiate.
- Bring your number and a compatible phone if you can — the free line is about service, not necessarily a free device.
- Stack the other perks. Ask about the gift card, buyout, or bundle credit that often comes alongside the free line.
The honest caveats
- "Free" is for 12 months, then standard pricing. It's still a great deal — just not permanent.
- You usually switch your mobile to that carrier to get the line, so weigh it against your current phone plan.
- A line you won't use isn't savings. The value is real only if you'd have a phone line anyway.
- Internet promo conditions apply separately — autopay/paperless and after-promo internet pricing are their own thing.
Frequently asked questions
As of 2026, the two big ones are Xfinity and Spectrum — both include one unlimited mobile line free for 12 months when you take a qualifying internet plan. The offers are similar in structure; the differences come down to which is available at your address, their network coverage, and the rest of the bundle (gift cards, buyouts, internet pricing). Other providers discount mobile-and-internet rather than giving a line outright.
A single unlimited line normally costs $25–$40/month, so 12 months free is worth roughly $300–$480. That often exceeds the value of a one-time gift card, which is why we call it the strongest current bundle perk. The value assumes you'll use the line — a free line you don't need isn't savings.
The line converts to the provider's standard mobile rate. At that point you can keep it and pay the regular price, cancel just the mobile line, or renegotiate. Mark your calendar for the 11–12 month mark so the rollover doesn't surprise you. Cancelling the line usually doesn't affect your internet, but confirm that when you sign up.
It's typically an unlimited talk/text plan with a high-speed data allotment before speeds may slow during congestion — standard for unlimited mobile plans. For one line of normal use it's genuinely unlimited in practice. Check the specific data terms for the current offer.
You can usually bring a compatible phone and your existing number, or buy/finance a new device. The free line covers the service, not necessarily a free phone — though providers sometimes run separate device promotions on top. Confirm device compatibility before switching, since Xfinity and Spectrum mobile run on Verizon's network.
Usually it requires a qualifying internet tier — often a mid-level plan or higher, not always the cheapest entry plan. The exact qualifying plans change with the promotion. An advisor can confirm which internet plan at your address unlocks the free line.
