Pro work with cable management and wiring.

Just got Sonic 10gbps fiber installed yesterday. The field service tech, Raymundo Reza was awesome. The work was professional. His supervisor Johnathan also great. Highly recommended.

Speed test over WiFi router.

Najib did a great job identifying the issues with our modem and troubleshooting why we lost internet connection.

I get a reliable 10G fiber service in San Jose (Naglee Park) from Sonic. The price is unbeatable.

They are advertising $49 month fee. What other fees will be added if I decide to switch from cable? Internet only. Do they charge for equipment?

They don't charge for installation but you will need a router (can rent for something like 5 - 10 dollars a month or get your own - I already had a Deco Mesh wifi network which works fine). I only wanted internet, but the service they offered… 

I am a resident of Los Altos (just off Angela drive) and have been waiting for Sonic to come to the area. Boy would it be nice to move from Xfinity! Now that you have permission to go underground, could you please come here soon?

Hello Tushar, Thank you for your interest in our Fiber service. We are rolling this out as fast as… 

When is it going to be available in San Jose Ca 95116?

I've talked to Sonic and they don't announce their expansion plans to avoid their competitors knowing them. What they encourage is going to their site (internet search for "Sonic Availability") and putting in a specific address and they'll let you… 

Is there a phone number I can call to get a quote and have it installed?

There web site lists: 888-766-4233

Is it true that during Covid, if you signup with Sonic, the installers will not enter your house and will only guide you on how to setup everything? I am technically challenged so I don't think this would work for me. Can anyone confirm?

Yes it's true. They walk you through all the steps. But if you have trouble setting up new technology or electronics you may need to ask someone else to help. It wasn't hard, but some of the cable parts are small amd need to fit together just right.… 

I would like to know how much it would cost per month to have sonic Internet access to use our smart TV and would also like to know if it's possible to have the connection hardwired by ethernet cables to our TV and laptop?

I pay $50 per month all in. The modem has an Ethernet output and I connect that to the router

Does anyone use an Arris Surfboard modem/router with Sonic? I want to change but have my own modem?

No. Arris Surfboard is a cable modem. Sonic offers both fiber optic and DSL (landline phone) connections, but not cable. You could sell the Arris modem on eBay.

FTTH in Burlingame: Unavailable on many streets due to utility poles that would fail wind / vertical loading and/or not enough space for proper anchor separation. Should we pursue replacement poles with PG&E or facilitate micro-trenching option?

PG&E are obligated to repair / replace / reinforce the utility poles they own, while the city is not obligated to allow micro-trenching. Advocating for PG&E to do the necessary work to get their utility poles up to standard seems to be the most… 

I ordered sonic internet and they said they will contact me 1-14 days to install as they need time to prepare? Its been almost 14 days but nothing so far! Did anyone have the sane experience? Should i call them or keep waiting?

Yes, you should call them. They have great customer service / technical support. Keep in touch with them and you will learn to love them. I've been their customer for 19 years and chose them because of great support.

Anyone in Daly City area using Sonic? Is it recommended for this area or around areas?

Hey Lina I personally don't know about people using Sonic in Daly city, sorry but I use it in San Francisco..

Great answers. I desperately need to leave landline carrier Frontier. Can anyone tell me if I were to get phone service, can I keep my number and how large is the calling area? Will I be able to get alerts from the Emergency Broadcast System?

You can keep your phone number. You can call nationally free. I'm fairly certain that Sonic charges for international calls. Our landline doesn't get Emergency Alerts so I doubt that Sonic would. I think that's only used for cell phones. You can… 

In San Francisco, Sonic is 1gbps speed, so does this mean it is Sonic Fusion Fiber - 100% fiber optics with FTTH (fiber-to-the-home) install? The street pole lines seem not to be fiber as they are so thick, unless it's Sonic Fusion DSL?

Our installation included a new line to and into our home and it is fast. Here is a sample: Your download speed is 969.66 Mbps… 

Hey, I'm getting my service installed this week by an AT&T worker, is there anything I should know before getting it installed? Do I have to pay an extra fee afterwards?

Hi Roque, depends. They charged me for changing the preexistent dish antenna.. Check the package (promotion) you got and ve sure that includes installation

So Sonic Fiber isn't available in my area, but their other internet service is(the one with AT&T) it said that upload speeds were around 25 mbs, is that true ?? Is it really worth it?

I can only tell you that I am much further down the list to get fiber, my download through at&t is about 23 mbps.. at&t has many specials and deals that you need to get every year (as prices go up) I have dealt with sonic about 5 times and I… 

Any users in Santa Rosa? I'm really tired of paying for and dealing with Comcast, but need to know the connection will be reliable and the speed will be enough.

I have them and live off Occidental RD and Brittan LN. I can't wait for my year to be up....I'll be switching asap. Slow speeds, my modem/ router is constantly dropping my Wi-Fi connections. There's only so many times I can reboot the modem/router… 

I'm so tired of my slow running AT&T IP so I'm looking for an alternative. Had a beef with Spectrum now looking elsewhere. Is Sonic a good replacement as far as speed is concerned?

Yes. My overall WiFi speeds on my phone are as follows: PING: 4ms… 

Any users in West Hollywood, CA?

I'm in the Beverly/Grove area. I've had them for 6 months. Sunday, November 19, my service went out. Internet and phone, which are bundled. It will be a week before they can send at&t dispatch to find out what the problem is. I don't know if this is… 

I signed up for their $40/month promo. However, I'm forced to rent their router ($9.50/month) otherwise I'll lose my $10/month discount. Is there anyway to only have their advertised $40/month price and not $62.xx which I'm paying now? Thanks

From their Customer Support: "You may opt out of the equipment rental and purchase your own compatible router for service, however you will lose any existing promotions currently on your account." ... In other words, service goes from $40/month to… 

Any users in Petaluma? How is the service? Any comments on the TV, phone, internet package? Advice? Greatly appreciated!

I'm in the East Bay and it's great. I would use their website to see how far you are from one of their centers and see the speed you would get

I usually don't have time to write reviews, but I had to take the time to recognize this location &…read morethe great customer service provided by Luis. I had some issues with my mobile acct & after spending several excruciating mins on 2 calls on 2 different days..I decided I needed to go into a location. As soon as I walked in, Luis had it cleared up & my bill paid within 10 mins. Great Job & Thank you!!

I was in this store last Sunday afternoon. Two employees were helping small groups of customers…read more(family plans, I think), and I was next in line. It became clear it was going to take a while, and I overheard that the manager was at lunch. Fine -- I opted to wait. My issue isn't really the 35-minute wait. It's that during that entire time, neither employee acknowledged the growing line behind me. And by "acknowledged," I mean not even a glance. The line eventually grew to 9-10 people, and not once did either employee say something as simple as, "Thanks for your patience while we help these customers." That's customer service 101. No one was asking them to rush or abandon the customers they were helping. Just acknowledge the people who are standing there waiting. Even when I finally got to the register, there wasn't a cursory "Thanks for waiting." Nothing. These are basic courtesy/customer-service skills I would expect Xfinity to include in its training. I left wishing I could transfer my service elsewhere. Very disappointing experience. 2 out of 10.
