Sonic Internet: 10 Gig for $49.99 With Taxes In, $59.99 With a Phone Line — and a $40 Card in LA and Dallas

Sonic internet at two live Bay Area addresses in September 2026 comes down to one question — do you want the phone line? At a 10 Gig street in Oakland, Standard Fiber 10 Gigabit is $49.99 a month for 12 months, then $59.99, taxes included, and Fusion Fiber 10 Gigabit is $59.99, then $69.99 with a home phone line bundled in. At an older 1 Gig street in San Francisco, Fusion Fiber 1 Gigabit is $49.99 then $59.99 with the phone line.

Every Sonic internet label says no contract, $0 installation, $0 early-termination fee, unlimited data and 3 ms latency. In its 2026 launch markets — Los Angeles and Dallas — Sonic says service starts at $40 with no introductory rate at all. The only extra is Wi-Fi, an optional device “starting at $5” a month.

Last updated: 7 September 2026. Prices pulled from Sonic’s availability checker at two live addresses on September 7, 2026 — a 10 Gig street in Oakland’s Rockridge district (94618) and a 1 Gig street in San Francisco’s Mission (94103) — including the FCC broadband labels on each results page, plus Sonic’s May 7, 2026 Los Angeles and Dallas launch release; refreshed monthly.

What are the Sonic internet plans and prices?

Sonic internet does not sell speed tiers. At any fiber address you get the fastest speed the local build supports — 10 Gig on Sonic’s newer plant, 1 Gig on the older Bay Area fiber — and the choice is whether to take Fusion (with a phone line) or Standard (internet only). Here is the ladder as it stood on September 7, 2026, built from two live checks and Sonic’s launch release.

Two things stand out. First, the phone line is the $10: Standard Fiber 10 Gig is $49.99 and Fusion Fiber 10 Gig is $59.99 for the same 8,700 Mbps, and Sonic prints the difference on two side-by-side labels.

Second, the Standard label says “Governmental Taxes and Fees: Included in Price,” so $49.99 then $59.99 is the whole bill, while Fusion adds voice taxes for a line with spam blocking, number porting and unlimited calling to more than 60 countries. A 1 Gig street in the city pays the Fusion price for the slower speed — which is the only real penalty for being on older fiber.

What happens when you check a real Sonic address?

The Sonic internet checker is the cleanest in this series and, unusually, puts the FCC broadband label right on the results page. A residential address in Oakland’s Rockridge district (94618) returned “Congratulations! You’re getting 10 Gigabits — America’s Fastest Internet!” and two cards with labels: Fusion Fiber 10 Gigabit at $59.99 (introductory for 12 months including a $10 discount, $69.99 after, one bundled phone line, voice taxes extra) and Standard Fiber 10 Gigabit at $49.99 ($59.99 after, “Governmental Taxes and Fees: Included in Price”).

Both Sonic internet labels: no contract, $0 one-time fees, $0 early-termination fee, 8,700 Mbps typical each way, 3 ms latency, unlimited data, optional Wi-Fi device from $5.

A public address in San Francisco’s Mission (1600 15th St, 94103) returned a single Fusion Fiber 1 Gigabit card at $49.99 — the same introductory structure, $59.99 after, 940/940 Mbps typical — with no Standard option and no 10 Gig, because that street is on Sonic’s older 1 Gig plant.

We also tried Santa Rosa City Hall and Dallas City Hall; both returned “No service is available — yet,” which is a reminder that Sonic internet is a street-by-street build even in its home county and that the Dallas launch is still lighting addresses. Enter your address in our internet comparison tool to see Sonic next to Xfinity, AT&T Fiber, Astound and the 5G carriers, then run Sonic’s own checker for the label at your exact address.

What fees does Sonic add to the advertised price?

Add it up and a Sonic internet bill on a 10 Gig street is $49.99 for the first year and $59.99 after, taxes in, plus $5 if you rent Sonic’s router — or $10 more each way with the Fusion phone line and its voice taxes. That is one of the cleanest fiber bills on this site: the $10 step at month 13 is the only moving part, and it is printed on the label rather than buried in a footnote.

How fast is Sonic internet really?

On the 1 Gig plan the label says 940 Mbps each way at 3 ms, which is the practical ceiling of gigabit Ethernet and what a wired test should show. On 10 Gig, the Oakland labels say 8,700 Mbps each way, again the overhead-limited ceiling of a 10 Gig port — and you will need a 10 Gig-capable router and NIC to see anything close to it over a wire, and Wi-Fi 6E or 7 to get past 2 Gbps wirelessly.

Sonic internet is building its newest plant on 50G PON with Adtran, which is why every new address is 10 Gig rather than 1 Gig and why the company markets itself as “the fastest internet in America” (PCMag) and a CNET People’s Pick over Google Fiber and Verizon Fios for reliability.

The catch is the older plant. Sonic internet began as a dial-up and DSL provider in 1994 and its first fiber, in Sebastopol in 2013, was 1 Gig; a large share of its Bay Area footprint is still on that generation, which is why our San Francisco check returned 1 Gig rather than 10. Sonic says it has built only 10 Gig since 2024, so the mix shifts every month.

The Sonic internet pricing quirk is that a 1 Gig street gets only the Fusion card at $49.99, while a 10 Gig street gets Standard at $49.99 and Fusion at $59.99 — so the 1 Gig customer pays the phone-line price for the slower connection.

Where is Sonic internet available?

Sonic internet’s parent, Sonic Telecom, was founded in September 1994 in Santa Rosa by Dane Jasper and Scott Doty, who had run networking at Santa Rosa Junior College. Jasper ran it for three decades and remains on the board; the CEO today is Nathan Patrick, formerly chief technology officer. The company is privately held and headquartered in Santa Rosa.

The Sonic internet fiber footprint covers more than 70 cities: San Francisco, Oakland, Berkeley, Richmond, San Leandro, Hayward, San Mateo, Redwood City, Palo Alto and Santa Clara around the Bay; Sonoma, Napa and Sebastopol in the North Bay; Sacramento; and a Southern California cluster including Pasadena, Burbank, Long Beach, Irvine, Anaheim, Huntington Beach and the Los Angeles build launched in May 2026.

Dallas is Sonic internet’s first market outside California. The May 7, 2026 release said construction was under way in both Los Angeles and Dallas “with addresses being activated daily through the end of 2026,” at “starting at $40/month” with “no contracts, no introductory rates” — a lower and flatter card than the Bay Area’s $49.99/$59.99, presumably because Sonic is the challenger there rather than the incumbent alternative. If you are in either city, sign up for the Sonic internet address alert; if you are in the Bay Area, the checker will tell you whether your street is 1 Gig or 10 Gig today.

How does Sonic internet compare to Xfinity, AT&T Fiber and Astound?

Against AT&T Fiber, Sonic internet is $30 a month cheaper for a symmetrical gig and, at $49.99 for 10 Gig with taxes included, roughly $195 a month cheaper than AT&T’s 5 Gig, which is the whole argument. Against Xfinity and Astound cable, Sonic internet matches or beats the promo price with a 1,000 Mbps upload instead of 35 or 50, and it does not raise the price by $30–$40 at month 13. Against 5G, the carriers are $10–$15 cheaper with a phone plan and hold price longer, but deliver a fraction of the speed; the only case for 5G in Sonic territory is a renter who moves every year.

Is Sonic internet worth it?

Yes, and it is one of the two or three easiest recommendations on this site. Symmetrical fiber from $49.99 — 10 Gig with taxes included, or 1 Gig with a phone line — free install, no contract, no cap, a $0 ETF on the label and a $10 step at month 13 that Sonic prints rather than hides — plus a 30-year-old company that publishes a privacy pledge and tops Consumer Reports’ satisfaction ranking. If Sonic internet reaches your address, the decisions are whether the phone line is worth $10 and whether to rent the $5 router or bring your own.

Think harder only about two things. If you are on a 1 Gig street and want 10 Gig, there is no upgrade to buy — you wait for the rebuild, and until then you pay the Fusion price whether or not you want the phone. And if you are in Los Angeles or Dallas, check the address before you cancel anything: “activating daily through the end of 2026” means your block may be months away, and the $40 card there is a starting price whose speed Sonic has not spelled out publicly.

What comes with Sonic Fusion, the VPN, email and phone?

Fusion is Sonic’s name for internet plus phone, and the phone half is more than a token: unlimited calling to 60-plus countries, spam-call blocking, number porting, a fax line, and a Mobile Communicator app that takes the home number on your phone. Every Sonic internet account also gets a free VPN, 15 email accounts with 1 GB of storage, personal web hosting and a domain, and fax-to-email.

Sonic sells a mesh Wi-Fi system for whole-home coverage and lets you bring your own router. The company’s privacy policy pledges never to voluntarily sell or share member data and to uphold net neutrality — unusual language for an ISP and part of why its reviews read the way they do.
