Compare Optimum and T-Mobile 5G Home Internet head to head
The speeds and service you get from both T-Mobile and Optimum depend entirely on where you live. T-Mobile offers fiber internet in a tiny portion of its footprint, but 5G fixed wireless internet everywhere else. Your connection quality depends on your distance from the tower. Optimum offers either cable or fiber internet, with differing speeds and prices in different areas.
You’re more likely to get fast speeds with Optimum, and prices are lower for at least a year, but T-Mobile’s superb customer ratings prove that speed isn’t everything.

Plans and pricing: Optimum vs. T-Mobile 5G Home Internet
If you live in an area with Optimum cable or fiber internet, you’ll get faster and more reliable service than you would with T-Mobile 5G. However, fiber internet from either Optimum or T-Mobile is a great choice.
Just keep in mind that Optimum’s rates typically go up after 12 months—something you don’t have to worry about with T-Mobile. Both companies offer free Wi-Fi equipment.
Optimum plans and pricing
| Package | Price* | Speed |
|---|---|---|
| 300 Mbps Internet | $30/mo. | Up to 300Mbps |
| 500 Mbps Internet | $40/mo. | Up to 500Mbps |
| 1 Gig Internet | $50/mo. | Up to 940Mbps |
| 2 Gig Fiber Internet | $60/mo. | Up to 2,000Mbps |
| 8 Gig Fiber Internet | $90/mo. | Up to 8,000Mbps |
* Offers and availability may vary by location and are subject to change. Read disclaimers.
Optimum’s plan roster covers all the broadband bases. We like the 300 Mbps Fiber Internet plan best, as you get blazing-fast symmetrical speeds for a relatively low introductory rate. Its 300Mbps symmetrical speeds may be overkill for some homes, but at $30 per month, you’re not sacrificing much for the extra speed.
If you need faster speeds, Optimum has several gigabit plans, but watch for price hikes. Optimum usually raises prices by $15 per month in year one, and then again in year two.
T-Mobile 5G Home Internet plans and pricing
| Package | Price* | Speed |
|---|---|---|
| Rely Home Internet | $50/mo. w/ AutoPay, plus taxes and fees. | Up to 354Mbps |
| Amplified Home Internet | $60/mo. w/ AutoPay, plus taxes and fees. | Up to 498Mbps |
| All-In Home Internet | $70/mo. w/ AutoPay, plus taxes and fees. | Up to 498Mbps |
* Offers and availability may vary by location and are subject to change. Read disclaimers.
Optimum offers faster speeds and lower prices in most places, but its customer service policies aren’t great. Those low introductory rates feel like a win in the beginning, it’s important to know they could go up by $30 per month after two years.
Meanwhile, T-Mobile offers the conveniences of 5G and stress-free plan policies, plus fiber in a few areas. The setup is super simple—no cables, appointments, or technicians required. Also, moving the gateway to a better spot is as simple as connecting it to power. Any other type of internet service requires rerouting the cabling in your home.

Availability: Optimum vs. T-Mobile 5G Home Internet
T-Mobile’s 5G home internet coverage spans the entire continental U.S. because it runs on excess capacity from T-Mobile’s enormous cell network. It’s fiber network, however, is new and available only in a few places.
Optimum’s hardwired cable and fiber connections are present in 21 states, including a few particularly dense pockets in the east (most notably in the Tri-state area) and coverage sprinkled throughout the South that spills over into Texas and Oklahoma.

Final call: Optimum vs. T-Mobile 5G Home Internet
If you’re after the fastest speeds, Optimum is the way to go. Every one of its internet plans offers faster speeds than T-Mobile. But the trade-off is higher monthly rates and the usual ISP annoyances, like rental fees, term contracts, and price hikes.
On the other hand, if you have average internet needs and want simple, no-hassle internet, T-Mobile’s breezy customer experience has received excellent customer feedback.
