Frontier Business Phone: Honest Review & Alternatives
Updated September 2026 · how we test and make money
Frontier acquired Verizon's landline business across Florida, Texas and California in 2016, which is how a great many businesses ended up as Frontier customers without ever choosing them. If your phone lines were Verizon and now say Frontier on the bill, that is what happened. Verizon has since bought Frontier itself, and Frontier now calls itself a Verizon company. The service still carries the Frontier name, and nothing on this page changes because of it.
That history of inherited accounts explains most of what follows. It also explains the most practical point on this page: transfers away from Frontier can stall on paperwork, because account records that changed hands in an acquisition often don't match what the business has on file.
Worth keeping if
A business in a Frontier fiber area that wants internet and phone from one local provider and does not need mobile apps, texting, or remote-worker features.
Time to switch if
Anyone still on inherited copper lines paying legacy rates — that is the clearest upgrade case in this entire category.
What it really costs
Traditional Frontier business lines land in the same territory as other legacy copper — commonly $50–70 per line per month before long distance, with taxes and fees on top. Frontier has been investing heavily in fiber, so in some areas the more relevant offer is fiber internet with phone bundled, which is a better product than the copper it replaces.
The pricing complaint we hear most is not the headline rate but the drift: bills that creep upward over years on accounts nobody reviews, for lines nobody has audited. Legacy accounts are where money quietly leaks.
The honest assessment
What it does well
- Substantial fiber build-out in parts of Florida, which is genuinely good infrastructure where you can get it
- Local presence and technicians in markets the national carriers underserve
- Traditional lines are reliable at the basic job of providing dial tone
- Bundling phone with fiber internet can be reasonable value where the fiber is available
Where it falls short
- Legacy copper accounts inherited from Verizon carry outdated records, which makes porting away slower and more error-prone than average
- Feature set on traditional lines is minimal against any modern cloud system
- Customer service reputation is weak, particularly on older accounts
- Per-line pricing scales poorly as a business adds staff

How to switch away from Frontier Business
- 1
Pull a current bill and work from it, not from memory. This matters more with Frontier than with most carriers. The authorized name, account number, and service address must match Frontier's records exactly. Accounts that moved over from Verizon often carry details that no longer match the business as it is today.
- 2
Audit the lines while you are looking at that bill. Long-held accounts routinely include lines for a fax nobody uses, a modem long since retired, or an alarm circuit that was replaced years ago.
- 3
Allow more time than usual. Budget three to four weeks to move several lines off an older Frontier account, and don't be surprised by a rejection over a records mismatch. It doesn't mean anything is wrong; it is the normal shape of this particular move.
- 4
Keep the fiber if you have it. If Frontier fiber is your internet and it is good, keep it and move only the phone service; a cloud phone system runs over any connection.
The step that matters most is the last one everywhere: never cancel before the numbers have moved. Our guide to number porting covers the paperwork that causes most delays.

Frontier Business questions
Is Frontier part of Verizon now?
Yes. Verizon bought Frontier, and Frontier now describes itself as a Verizon company. The service still carries the Frontier name. For moving your numbers nothing changes: the name, account number, and service address you submit must still match the account records exactly.
Why did my Verizon business phone become Frontier?
Frontier acquired Verizon's landline operations in Florida, Texas and California in 2016, so those accounts transferred wholesale. Nothing about your service was supposed to change, but the record-keeping from that transition is exactly why porting numbers away from these accounts is more error-prone than average.
How much does Frontier business phone cost?
Traditional business lines commonly run $50–70 per line per month before long distance and fees. Internet-based alternatives run $10–30 per user with far more included — so a business with several legacy lines is usually looking at a substantial monthly saving from switching.
Why is porting away from Frontier difficult?
Because many of these accounts came across from Verizon with records that no longer match reality — an old business name, a service address formatted differently, an authorized contact who left years ago. Ports are rejected on exactly those mismatches. Copy every detail from a current bill rather than typing what you believe is correct, and expect the process to take three to four weeks.
Should I keep Frontier fiber internet if I change phone providers?
If the fiber is good, yes. Cloud phone systems run over any internet connection, so keeping Frontier for internet while moving the phone service is entirely normal. Just ask what unbundling does to the internet rate before you cancel the phone portion.
Can I keep my number when leaving Frontier?
Yes — porting is your legal right and Frontier cannot refuse a valid request. Keep the existing service active until the transfer completes, because canceling first releases the number and it can be lost permanently. Given the records issues on these accounts, this rule matters more here than almost anywhere else.
