Xfinity’s main draw is its Unlimited 5G plan which promises users 5G connectivity wherever it is available across the United States (US).
Xfinity is a virtual mobile network operator (MVNO) that provides connectivity to Comcast’s (physical) infrastructure. So although Xfinity doesn’t operate a network of its own, users should be able to enjoy the same quality of service as a Comcast user. This means that wherever Comcast has provisioned 5G it should be available to Xfinity Mobile subscribers.
Xfinity Mobile's comprehensive features and reliable service make it frequently mentioned among the top 10 best cell phone plans.
For those that want to check in advance whether coverage is available in their area, Xfinity has a network coverage checker lookup tool. Users just need to enter their zip code in order to see whether 5G reception is available in that locality.

Xfinity Mobile offers both per gigabyte pricing (“per gig”) as well as unlimited data plans. The per gig pricing is tiered according to the number of gigabytes of data provided. Those who are on the plans don’t have to worry about sticking rigidly to their limit. Additional data is billed at $15 per gigabyte and users are able to easily switch between the metered and unlimited plans.
Of course, unlimited data rarely truly means “totally unlimited.” Comcast has provided an Acceptable Use Policy For Xfinity Internet which is posted on the Xfinity site. That policy includes two important clauses:
The unlimited plan offers the lowest per-line cost for 5G coverage of all service providers for plans with 4 lines, reducing the cost per line from $45 a month to just $30 a month. That means the more lines you add, the more you save, making this plan a great option for larger families.
By The Gig pricing:
| Data allowance (GB) | Price (per month) |
|---|---|
| 1 | $15 |
| 3 | $30 |
| 10 | $60 |
| Unlimited pricing | |||
|---|---|---|---|
Number of lines | Intro | Plus | Premium |
| 1 | $45 | $55 | $65 |
| 2 | $30 | $40 | $50 |
| 3 | $30 | $40 | $50 |
| 4 | $30 | $40 | $50 |
| 5-10 | +$20 each added line | +$30 each added line | +$40 each added line |
There are some other important differences between the plans:
Users have two means of getting activated on the network:
Xfinity Mobile provides users with flexibility in terms of how they wish to engage with the network. With the Bring Your Phone option (also called Bring Your Own Device, BYOD) users can keep their existing devices and port them straight onto the network. The option works for most iPhone, Galaxy and Pixel devices. Additionally, the company operates an online store that allows users to buy a device that is guaranteed to be compatible with the network. Users can select from phones by:
The By The Gig plan includes higher quality mobile cellular services during periods of peak network traffic.
Those on the Unlimited subscription get HD Pass which offers a similar performance boost even when the network is crowded with subscriber traffic.
Xfinity gives users access to 5G nationwide wherever it is available and operates an online checker where users can see whether their devices are compatible with the new network technology.
As a MVNO for Comcast, Xfinity operates the network that RootMetrics named the highest-ranked in its 1H 2020 US Report.
5G can provide users with speeds that are up to 20 times higher than 4G network performance.

Xfinity customer support is provided by Comcast who operates a status center that informs users of outages as well as a 24/7 chat facility and social media support over both Reddit and Twitter.
Between the personalized support and the community forums, users should be able to get any network or connectivity issues they might be experiencing resolved expeditiously.
