Compare · beyond cable & data caps

Swell vs Xfinity, the honest version.

Xfinity uses hybrid fiber-coax technology, where fiber runs to your neighborhood node and coaxial cable connects to your home. Bandwidth is shared among neighbors on the same node, so a fully fiber network behaves differently in practice.

Unlimited vs 1.2 TB

No data caps

Xfinity caps most plans at 1.2 TB/month and charges per 50 GB over. A household streaming 4K, gaming, and working from home can easily exceed this. Swell never caps your data.

0 vs 1–2 years

No contracts

Xfinity’s best prices require a 1–2 year contract with early termination fees. Swell never requires a contract. Stay because you want to, not because you have to.

Symmetrical vs 35 Mbps

Symmetrical upload

Xfinity’s cable upload tops out around 35 Mbps even on their fastest plans. Swell’s fiber delivers the same speed uploading as downloading, critical for video calls, cloud backup, and smart home devices.

Why customers switch

Real reasons people move from Xfinity to Swell.

Break free from data caps

A 1.2 TB monthly cap sounds generous until a family of four streaming 4K, gaming online, and working from home burns through it in a few weeks. Overages add up fast. Swell has no data caps, ever.

Symmetrical speeds that actually work

Cable advertises impressive download speeds, but upload maxes out around 10–35 Mbps. That’s a bottleneck for video calls, cloud backups, security cameras, and streaming. Swell’s symmetrical fiber gives you the same speed up and down.

No contract, no risk

Cable locks you into 1–2 year contracts with early termination fees to get the best prices. Swell’s month-to-month pricing means you stay because the service is great, not because you’re trapped.

No equipment rental fees

A monthly gateway rental adds up to real money for equipment you don’t own. Swell includes a Wi-Fi 7 router at no charge with every plan.

Transparent billing

Cable bills are known for surcharges and mysterious fees. Swell bills show one line item: your internet plan. Nothing else.

Local support, not a maze

National support can mean phone trees, hold times, and retail-store visits. Swell’s local team picks up the phone, knows your neighborhood, and resolves issues quickly.

Questions

Swell vs Xfinity, what you need to know.

Does Xfinity have data caps?
Xfinity enforces a 1.2 TB monthly data cap on most plans, with overage charges and an unlimited add-on for an extra monthly fee. Swell has no data caps on any plan. Use as much data as you need.
Is Swell faster than Xfinity?
Swell offers symmetrical fiber, so upload and download speeds match. Xfinity’s fastest cable plan advertises high download speed but much lower upload. Swell shows its current exact speed options after address qualification.
Does Xfinity require a contract?
Xfinity’s best promotional prices typically require a 1–2 year term agreement, and canceling early results in a fee. Swell never requires a contract, so you can cancel anytime with no penalties.
Can I switch from Xfinity to Swell?
Yes. If Swell is available at your address, switching is easy. We provide free professional installation and set up your Wi-Fi 7 router. Swell service can be installed while your current service is still active, so there’s no downtime.
How much does Xfinity really cost per month?
The advertised price often doesn’t include equipment rental, potential overage charges, and various surcharges, so a realistic bill is often higher. Swell’s price includes everything: internet service and a Wi-Fi 7 router, with no hidden fees.
