Sonic Fiber vs. T-Mobile Home Internet: What Switching Cost Me

The next thing I decided to tackle in my spending audit plan was my internet. It seemed like a natural next step after looking at my phone bill.

Spoiler alert: I didn't save money on this one. But I did make a switch that got me better internet with better customer service. My monthly cost went from $50 to $49.99.

Why I Chose T-Mobile Wireless in the First Place

When I first moved into my building, my options were Comcast cable or a wireless alternative. After nightmare customer experiences with Comcast in the past, I was resolute about not going with them. I opted for T-Mobile 5G Home Internet, as recommended by a neighbor.

T-Mobile 5G Home Internet Review: What I Liked and Didn't

I used it for a couple of years at $50 a month. It was mostly fine, with some finicky connections here and there. I really liked how easy it was to install: you plug the thing into the wall and presto! What I didn't love was that the freestanding unit had to be positioned on a table near a certain window and pointing just right to get a good signal.

The Sonic Fiber Internet Deal

When my HOA announced it was negotiating high-speed internet for our building, I was happy to hear they went with Sonic Internet. I'd been a Sonic customer before and found their customer service excellent. I remember being surprised to call a local phone number and reach a helpful, kind human on the other end.

For 10 Gbps fiber, the cost was $59.99/month. Residents in my building also got two free months and free installation.

I took the deal.

Should You Buy Your Own Router or Rent? (Save $10/Month)

At the install, I declined to rent Sonic's router and decided to buy my own. The installer recommended this one for my 1-bedroom apartment, which I ordered from Amazon for $99.66 after tax. It arrived two days later.

I'm linking Sonic and the router I bought because I use and love both. I'm not linking T-Mobile, for obvious reasons.

At $10/month saved, the router pays for itself in about 10 months.

Tip: Have Your Own Router Ready Before Install Day

I wish I'd had my router in hand before the install day. The tech said I could use the rented router until mine arrived and then return theirs. But returning equipment, confirming they received it, making sure I was prorated correctly, and double-checking it all sounded like a headache. So even though I wanted my internet up right then, I'm glad I waited the two days without it. Setting up my own router was easy.

How to Cancel T-Mobile Home Internet (It Was Like Pulling Teeth)

Canceling T-Mobile was painful. Very painful. I was passed from one rep to another, each with their own hold time. They had trouble locating my account. Finally, one found it but said they lacked the authority to cancel it. Only a manager could. After several more minutes on hold, I was transferred to a manager who finally canceled my service.

To their credit, I got detailed instructions on how to return the equipment to "avoid non-return and damage charges," whatever those might have been. Rest assured, I bubble-wrapped that thing like nobody's business, and I was relieved to get a confirmation of receipt and a $0 equipment charge.

The next month, I got a bill: "Balance Due: $0.17." What in the world was that for? I'll never know since I couldn’t bring myself to go through their customer service again. I paid it and was done.

Why Customer Service Matters When Choosing an Internet Provider

I've now officially added T-Mobile to the list of giant telecom companies I will never use again. Any company that makes it difficult and painful to cancel a service is immoral, in my opinion. How many people are spending money they don't want to because of this hurdle?

Sonic, on the other hand, I wholeheartedly recommend. Their customer service number is now an 888 number instead of a northern California local one, but there are still humans on the other end. When I scheduled my installation, I spoke with a person I still have saved in my phone as "Sean Sonic Internet." He walked me through the process and was on hand for my questions.

It Feels Good to Pay a Company I Like

I also like Sonic's story. It's a classic underdog tale. They started in the '90s with two young guys at a community college in northern California just trying to get their campus online. They grew the company successfully, and it's much bigger now, even reaching into LA and Texas. I love that their headquarters remains in that small northern California town. They have a good product and great customer service, and I'm glad my money goes to them.

As I learn more about the FIRE movement, I’m realizing it’s not only about optimizing costs. Saving is critical, but so is aligning your spending with your values. Choosing a company I respect and offers the same or better product, even when it saves me almost nothing, is a good thing and worth the energy to figure out.

The Real Cost of Switching Internet Providers

• T-Mobile: $50/month
• Sonic: $59.99/month, minus $10/month for not renting the router = $49.99/month
• Two free months: $99.98 saved (2 × $49.99)
• Router: -$99.66
• Final mystery T-Mobile bill: -$0.17

That brings my one-time savings to $0.15. Add the 0.01/month difference (50 vs. $49.99), and technically, I came out ahead.

The Verdict: Was Switching to Sonic Fiber Worth It?

Yes. I now have faster, more reliable fiber internet from a company I genuinely want to support. By putting the savings from the promotional deal toward my own router, my monthly cost didn't change. That's a win!

Spending Audit Accumulated Monthly Savings

• Cell Phone Audit resulted in savings of $30.24/month
• Internet Audit resulted in savings of $0.01/month

That brings my total savings so far to $30.25/month.
