Xfinity Mobile is yet another addition to the umbrella of internet services by Comcast. It’s (only) available to existing customers. The idea is that you already getting the cable and internet from them, you might want to add the mobile to the mix.

The value you obtain from bundling these services is unparalleled. This is what at least the subscribers think. But is it true? Let's find out!

Xfinity Mobile Customer Reviews

Some long-term users have shared their feedback about the service. Here's what they have to say:

Excellent experience after switching to it from a slow AT&T internet. The website and app are user-friendly, which makes bill payments much simpler. I wish I had switched earlier. Overall, satisfied!
Bryan O
I stay in Chicago, where I have access to a fast 5G connection, but my office in Brookfield sees a major drop in speeds, so I’m unable to play PUBG there in my past time. Understood that Brookfield is outside the circle of Verizon’s Ultraband.
Florence H
Got to know I must keep my Xfinity cable internet to continue my Mobile connection. And I must continue to pay $25 if I wish to continue. That’s a waste.
John T
Already being an xfinity user, I got their mobile unlimited plan and it provides super-fast internet in my home in Minneapolis. My husband and I stream 4K movies and web shows without any buffers.
Eddie E
The service is great, and it didn’t disappoint me. I have enough signal bars throughout the day to do whatever I wish. The only thing that’s bothering me is the automatic payment. They (xfinity) should offer flexibility.
Michelle M
I called tech support regarding the issue I was having with the connection. It took me around a day to connect with them and three days to get the problem solved. Service is good but support could be better.

Is Xfinity Mobile Good? [Detailed Review]

I have been a loyal Xfinity customer for two years now, and I recently got their cellular plan last month to work on my phone to use fast internet on the go alongside unlimited calls and messages.

Aside from basic web browsing and sending emails, I used the internet to stream movies and play online games. In the subsequent sections, you will find my honest opinions and experiences in using the network, alongside its pros and cons, so you can make an informed decision.

So without further ado, let’s delve deep into it.

Internet Speed

Xfinity Mobile uses Verizon’s 5G Ultra Wideband and C-band. 5G Ultraband is the fastest 5G by Verizon which I tested from Miami Beach, Florida. Also, it’s worth mentioning that I subscribed to the Unlimited Intro plan.

Using the Ookla speed test tool, I witnessed download speeds of 448 Mbps and upload speeds of 41 Mbps.

Xfinity Mobile Speed Test

Now I moved a bit farther where the Ultraband was not available, and the 5G speeds dropped to 110 Mbps and 25 Mbps, respectively, for downloads and uploads.

Xfinity Mobile Internet Speed Test

After the entire day of using the 5G network for several tasks, I exhausted the set data limit of 20GB, and the speed dropped to 60 Mbps and 12 Mbps. But the speeds are still enough to stream 4K videos and stay online on other tasks without any issues.

Performance & Reliability

Aside from speeds, performance primarily depends on latency, so let’s discuss that first. When using the Ultraband, values stay at 8ms, dropping off to 23ms, where Ultraband was unavailable. Further, exhausting my data limit, the latency value drops to 44ms.

I tested the gaming performance on my iPhone 15 (base), and to be honest, I wasn’t disappointed a tad. In peak performance areas, bandwidth-intensive FPS and battle royale games went like a breeze.

While in the other (where Ultraband wasn’t available), performance wasn’t that good, but I still managed to play games like Pokemon Go, Clash of Clans, and League of Legends.  And the thing is, there aren’t many fluctuations when you are sticking to a place to play games, stream movies, or download files.

Aside from gaming, the network was used to stream high-quality videos, web browsing, and send emails. Irrespective of where you are or within the data limit, these tasks were free of any jitters or drop-offs.

Availability / Accessibility

Xfinity Mobile operates on Verizon’s 5G network covering around 69% of the US population or 230 million people in ballpark numbers. While its 4G LTE network covers about 99% of Americans.

Here’s the coverage map of Xfinity Mobile 5G (Ultraband & C-band), as reported by FCC.

Costs & Contracts

In contrast to its other services (cable or fiber), Xfinity has a few fees attached to its mobile service. You won’t need to pay any access or activation fees, and only its monthly data plans range from $15 to $65 as long as you only connect the smartphone.

If you extend it further to your tablet or smartwatch, you must pay an additional fee of $10 per month. This makes it the most affordable 5G internet available, bettering Verizon and AT&T.

But the latter adds promos like free HBO Max subscriptions and bundled international data access. For similar services, Xfinity charges $5/$10 for a daily pass or data for a megabyte if you're traveling overseas.

Besides, you must continue paying $25 if you want to stick with Xfinity Mobile while discontinuing its Internet services. But as the connection comes with a no-contract setup, you can opt out of it at any time without having to pay any termination fees.

Another thing worth mentioning is Xfinity Mobile’s HD pass. If you have a 4G smartphone, paying $20 extra for the unlimited plan would let you stream HD videos once data is exhausted. But in 5G, there’s no HD pass, and you can watch HD videos without having to pay for a pass.

Installation & Setup

Installation is no rocket science and doesn’t need calling a technician, just like Xfinity self-install. Just follow the below-mentioned stepwise process to get it done within a few minutes, as follows:

Step 1: If you bought a new smartphone, open the box and take out the contents: nanoSIM card, charger, and any accessories.

Step 2: Open the browser on your laptop, search xfinitymobile.com/activate, create or log in to the existing account, and choose your phone.

select new number or retain the existing number

Step 3: Next, select whether to get a new number or retain the existing number.

Step 4: Press Activate. It takes around 10-15 minutes to complete the process.

Click on Activate

Step 5: You should receive an activation email that includes a new number if you’ve asked for one. If not, ignore it and proceed to the next step.

Step 6: Insert the Xfinity nanoSIM card and explore unlimited possibilities with high-speed 5G internet.

Xfinity Mobile Customer Service

Xfinity Customer Service

Setting up Xfinity mobile was a breeze and it took around a minute or two to complete. You’d find many FAQ pages on the Mobile app to find answers about billing, switching data plans, and setting up a service.

If you’ve any other questions, contact their customer support through Facebook messenger, text, or app chat with an estimated time given. Or you can directly call them at (888) 936-4968.

I first contacted them when the internet on my brother’s iPhone 13 wasn’t working properly and was frequently getting disconnected. The technicians took control of the phone and got it fixed in no time. Although I saw many complaints online about poor customer service, my experience was decent enough.

Learn More About Xfinity Mobile

Comcast launched the Xfinity Mobile service in 2017, and its growth curve has been going upward since then.

You would be surprised to know that the service provider doesn’t use or, rather, they don’t have their own cellular towers. In this case, Verizon’s network is coupled with the provider’s network hotspots.

In certain situations, getting an MVNO (Mobile Virtual Network Operator) is a better deal than subscribing to a major carrier whilst enjoying similar coverage.

The speed cuts down to an extent due to increasing traffic. But, this service is more about combining with other packages and getting more value out of it.

If you're an existing customer of their cable internet, you can add the mobile service and enjoy unlimited data, text, and talk at a mere $45 every month. Also, make sure you have a 5G-enabled device to access the internet.
