The query for T-Mobile landline plans reveals a crucial distinction: T-Mobile does not sell traditional landline (POTS, or Plain Old Telephone Service) service, which operates over copper phone lines. Instead, T-Mobile offers a Voice over IP (VoIP) solution called LineLink that connects your existing home phone equipment to the T-Mobile network via your home internet connection.
This article will explain the details of the T-Mobile LineLink service, outline its features and requirements, and provide alternatives for customers seeking a home phone solution.
T-Mobile’s Home Phone Solution: LineLink
The closest offering T-Mobile has to a landline plan is the LineLink service. This product is designed to replace traditional copper-wire landlines using modern VoIP technology, connecting calls through your existing home internet and the T-Mobile network.
How T-Mobile LineLink Works
LineLink requires a small physical adapter (the LineLink device) that plugs into your home internet router/hub and also provides a standard RJ11 phone jack. You simply plug your regular home phone (corded or cordless) into the LineLink device, and all calls are routed over the internet.
| Feature | T-Mobile LineLink Service |
| Technology | Voice over IP (VoIP) |
| Requirements | Active internet connection (recommended Cable or DSL) and an eligible T-Mobile postpaid voice line. |
| Pricing | Varies, but often significantly discounted for existing T-Mobile wireless customers (e.g., as low as $10 per month). |
| Included Features | Unlimited talk & text, Voicemail, Caller ID, Call Waiting, Call Forwarding, and Conference Calling. |
Note: LineLink service will not work during a power outage or an internet outage, as it relies entirely on power and your broadband connection.
Eligibility and Pricing
Eligibility for LineLink is generally restricted to:
- Existing Postpaid Wireless Customers: The service is heavily promoted and discounted as an add-on line for customers already on a T-Mobile postpaid plan (like the Experience plans).
- T-Mobile Home Internet Customers: LineLink is fully compatible with T-Mobile Home Internet, making it an easy bundle option.
- Pricing: While the initial cost involves buying the LineLink device and a SIM starter kit, the monthly service fee is typically discounted to around $10 per month when bundled with an existing postpaid T-Mobile line.
T-Mobile’s Wireless Home Phone Alternative
In the past, T-Mobile offered a device called Home Phone Connect that connected to the cellular network directly (like a cell phone, but for a home phone). This device, which did not require a broadband connection, has largely been phased out in favor of the VoIP-based LineLink device.
If your search intent is to find a home phone solution that doesn’t require traditional copper lines and allows you to keep your old phone, LineLink is T-Mobile’s modern answer.
Alternatives to T-Mobile Landline Plans (VoIP Providers)
If you are looking for a standalone home phone service or one that offers different feature sets than T-Mobile’s LineLink, several other VoIP providers offer competitive rates and advanced features.
| Provider | Technology | Key Differentiator |
| Ooma | VoIP (requires internet) | One-time purchase of a device (Ooma Telo Air); basic service is often free (plus taxes/fees). Advanced features require a Premier subscription. |
| Vonage | VoIP (requires internet) | Flexible, contract-free plans starting affordably; strong options for unlimited international calling. |
| AT&T | Traditional (copper) & Digital (VoIP) | Offers true Traditional Home Phone plans for those who need service that works during a power outage (though availability is shrinking). |
| Community Phone | Cellular-based (No internet needed) | Uses a dedicated base station that connects to local cell towers, providing a “landline” feel without relying on copper or broadband. |
Frequently Asked Questions
Can I port my old landline number to T-Mobile LineLink?
Yes. T-Mobile offers number porting services, allowing you to keep your existing home phone number when switching to the LineLink VoIP service.
Does LineLink use my mobile data allowance?
No. The T-Mobile LineLink service is a phone line only and does not use your T-Mobile wireless data allowance on your smartphone plan. It uses your home broadband internet connection (cable, DSL, or T-Mobile Home Internet) for calls, using a maximum of approximately 179 KB of data per minute.
Does LineLink support 911 services?
Yes. The LineLink service requires you to register a valid e911 address to ensure that emergency services can accurately locate your home if a 911 call is placed from the LineLink device.
Can I bundle T-Mobile Home Internet and a LineLink phone plan?
Yes. T-Mobile actively promotes bundling its 5G Home Internet service with its wireless plans, and the LineLink home phone solution is fully compatible with the 5G Gateway device. This allows customers to consolidate their home communication services with one provider.
