Xfinity is a great company that every consumer loves. You can have an idea by looking at the stats as to how Xfinity has grown its consumers and made themselves the favorite consumer network across North America. The topic is under discussion on various forums if Xfinity mobile is CDMA or GSM. Any person who wants to switch their networks to Xfinity, or want to upgrade their phone must have this question in mind as they need to have an appropriate phone that would be compatible with Xfinity network. To have a deeper look at the subject, let’s understand how Xfinity operates and what is the difference between CDMA and GSM.

Xfinity Mobile

Xfinity Mobile is a subsidiary of Comcast Telecommunications. They do not have towers or cellular networks of their own. Xfinity uses a virtual network based on Mobile hotspots and towers from Verizon to provide you with the best signal strength. Xfinity’s hybrid network combined with their best mobile hotspots across the US and renowned Verizon towers that are famous for their connectivity all over North America, you get the best coverage and quality no matter where you are. This ensures that you get the right bang for your bucks.

If you are looking to come aboard with Xfinity Mobile, the change is pretty simple for you. If you have an unlocked phone that can work on any network carrier is good to go with Xfinity as well. Xfinity also allows you to have the option of getting a brand-new cellphone from them at the time of sign-up that might be a deal you want to consider. However, if you have a phone purchased from some other carrier and you want to stick to it, it can cause some complications for you.

If you have purchased the phone directly from Verizon and you want it to work with Xfinity, that is quite possible as Xfinity is using the Verizon towers in the first place. However, cell phones purchased from other carriers such as T-Mobile or AT&T would not be compatible with Verizon or Xfinity. These carriers are using different technologies and another technology is locked or disabled most of the time on these phones that you purchase directly from the carriers. Hence, you need to be careful while making the choice. To understand the concept in a better way, let’s have a look at what these technologies are.

Xfinity Mobile CDMA or GSM

CDMA

CDMA is one of the most advanced protocols that you can have on 2nd and 3rd Generation communication that is also known as 2G and 3G. With 4G LTE the technology has changed and there are several bands of frequencies involved but that is a discussion for some other day.

For most communication over a phone, you might require to have 3G connectivity and Verizon uses CDMA for it. CDMA stands for Code-Division Multiple Access that refers to any of several protocols that can be used for transferring data wirelessly. It allows numerous signals to travel over a single transmission channel. This does not only optimize the use of the bandwidth available but also enhances transfer speeds, connectivity, and signal strength for most users.

Since Xfinity uses Towers rented from Verizon, they are a CDMA network. If you want to bring your current phone to Xfinity, you need to make sure that it is unlocked, either bought from Xfinity or Verizon directly or is CDMA complied. CDMA is not supported by most major network providers so their phones might not work on Xfinity for you.

GSM

GSM stands for Global System for Mobile Communication. It is widely adopted all over the world for 2G and 3G wireless communication. However, the fundamental flaw with the design is that it digitalizes, compresses, and then sends the data over a stream that carries one stream in a given time slot.

The purpose is as time-consuming as it may sound and causes you to have issues like slow data transfer speeds, lower communication, less signal strength, and more issues with connectivity. GSM is used by some major networks like AT&T and T-Mobile. However, it is not supported by Xfinity, Comcast, or Verizon in any possible way and GSM enabled devices would not be able to work on Xfinity.

  1. Be wary of bringing over your own phone. Nothing but issues thus far with Note 9. Horrible connection causing apps to perform poorly. Xfinity voicemail does not update with new messages.
