Phone and internet bundle deals can be worthwhile when the combined, ongoing bill is lower than two suitable standalone services. First identify whether the “home phone” is copper, cable-based digital voice or portable VoIP. Then compare equipment, later pricing, number transfer, how emergency calls get your address, and service during a power or internet outage.
Use the ZIP search to find area-level internet options. Ask each provider to confirm the exact address, phone service and written bundle total; a ZIP result does not approve a home.
“Landline” may mean digital voice over internet equipment
Sales pages often use “home phone” or “landline” for a service that is not an old copper line. Xfinity Voice, for example, is digital home phone service powered by Xfinity Internet and requires an Xfinity gateway or compatible voice modem.[1]
Ask the provider to name the technology in writing:
- Traditional copper voice: the phone line is separate from home internet, though local retirement or availability may affect ordering.
- Provider digital voice: phone service connects through provider equipment on a cable or fiber network.
- Independent VoIP: a separate phone company uses your broadband connection and may allow the adapter to move.
The distinction matters during an outage. The FCC warns that VoIP may not work when household power or the internet connection fails.[2] Do not assume a service remains available merely because the salesperson calls it a landline.
If you do not actually need home phone service, compare the bundle with a standalone plan using our guide to internet without cable TV or a phone line.
When does a phone and internet bundle save money?
A bundle saves only if its relevant total is below the alternatives for the period you expect to keep it. Request three written quotes from the same provider: internet alone, phone alone if sold separately, and internet plus phone. Then compare the bundle with an independent phone option using the same calling features.
Use this worksheet:
| Cost or term | Bundle | Separate services |
|---|---|---|
| Monthly amount now | ||
| Monthly amount after promotion | ||
| Internet equipment | ||
| Voice equipment or adapter | ||
| Installation and activation | ||
| Taxes and voice-related fees | ||
| Domestic and international calling | ||
| Cancellation or equipment balance | ||
| Backup-power equipment |
Do not count a TV channel package as savings if you wanted only cable internet and phone. For cable and internet bundle deals, ask which line items are actually required and which were added to create the advertised total.
The FCC requires a Broadband Consumer Label for every standalone fixed internet plan and says the label discloses price, introductory rates, data allowances and speeds.[3] Compare that label with the internet portion of the bundle. It helps reveal whether the package replaces a suitable entry plan with a larger internet tier.
If the current provider is raising the package price, follow the bill-comparison steps in why an internet bill goes up before removing the phone line or changing companies.
Keep your phone number without canceling it first
When switching in the same geographic area, the FCC says a number can generally move among wireline, IP and wireless providers.[4] Start service with the new company and ask it to port the number. Do not cancel the old phone service first.[4]
Give the new company the account information exactly as it appears on the old bill. Ask about a porting fee and keep the old service active until the new provider confirms the transfer. FCC rules call for a simple port to be processed in one business day, but wireline-to-wireless changes can still take a few days.[4]
Moving complicates the decision. The FCC says keeping the number may not be possible when moving to a new geographic area.[4] Ask the new provider to approve the number and new service address before scheduling cancellation. Our moving internet guide can help coordinate the old and new service dates.
Check 911 location, alarms and backup power
For portable VoIP, the FCC advises giving the provider an accurate physical address and updating it after a move so emergency service can work properly.[2] Ask whether the bundle’s voice service automatically sends the service address, how to update it and what visitors should know.
Power backup is also service-specific. Xfinity says its optional voice-modem battery supports the primary phone number only and can keep phone and alarm service operating for up to 24 hours under its stated conditions.[5] Its main Voice page also warns that voice and emergency service may stop after an extended outage.[1] A battery cannot restore a failed outside network.
Before relying on any bundle for a medical alert, fax, elevator, gate or alarm, ask both companies to confirm compatibility. Xfinity specifically tells customers with home security systems to arrange a compatibility test with the security provider before Voice installation.[5]
Questions to read to the salesperson
- Is this copper voice, provider digital voice or portable VoIP?
- What modem, gateway, adapter and battery does it need?
- What is the total now and after every promotion ends?
- Can you port my number, and should I keep the old line active?
- Which address is registered for 911, and how do I update it?
- What works during a household power failure or internet outage?
- Has my alarm or medical device been approved by its manufacturer for this service?
Compare bundle quotes, not support plans
The call option is for sales and plan comparison, not repair or billing support for an existing provider. Ask for both standalone and bundled written quotes, and do not cancel the old phone line until the number transfer completes.
Want TV in the bundle instead? Compare internet and TV bundles, or check whether DISH offers internet.
Frequently asked questions
Is a cable home phone a traditional landline?
Not necessarily. Xfinity describes Voice as digital home phone service powered by its internet network and requiring voice-compatible equipment.[1] Ask the provider to identify the connection type.
Can I keep my home phone number when changing bundles?
Usually, if you remain in the same geographic area. Start the port through the new provider before ending the old service; moving to another geographic area may prevent the transfer.[4]
Will bundled phone service work in a power outage?
Do not assume it will. The FCC says VoIP can stop during power or internet failure, while provider battery options have their own limits.[2][5]
