Is it T-Mobile GSM or CDMA?

In this blog we will answer the question ”Is T-Mobile GSM or CDMA?” with the latest information about T-Mobile’s performance.

Is it T-Mobile GSM or CDMA?

The telephone company T-Mobile works with GSM and newer technologies in its cell phones. So if you have a phone that works with a CDMA signal, it will not work for you if you want to become a T/-Mobile subscriber.

T-Mobile is a leader in cellular phone services and has long since withdrawn CDMA networks from its services.

It currently only operates GSM technology onwards, which is considered a second-generation network and we are currently transitioning to fifth-generation mobile networks.

Cutting-edge technology is very important for a company with the weight and size of T-Mobile, so they consider CDMA networks to be a thing of the past.

Why does T-Mobile use the GSM network?

T-Mobile uses GSM  because this type of cell phone works with a SIM card and can be used worldwide without any problems and is a data-driven network, although it is one of the first to be developed in the world, it is still popular.

Telecommunications have changed everyone’s life worldwide, which has led to the evolution of connectivity in the world. 

Networks are getting faster and faster and capable of handling a greater data load, T-Mobile is one of the leading companies that have developed great technology projects.

GSM networks are digital networks that are compatible with newer networks and can interact quickly.

They are able to exchange data quickly and that needs fits the communication requirements of today’s world.

In addition, today’s users like versatility and if they want to change their SIM card to another company, change their phone number, or simply upgrade their network, it can only be achieved from a second-generation GSM network onwards


This is a comparison of GSM and CDMA networks to understand their features and benefits.


  • CDMA technology is becoming obsolete because it allows few functions with the cell phone and the phones cannot use a SIM card, which greatly limits their performance and use.
  • CDMA is a technology that gives the user full access to the entire spectrum of available bands, so more users can connect at any given time. 
  • It is also capable of encrypting each user’s individual conversation and the voice data remains protected at all times so that only those participating in the call receive the data.
  • Phones using CDMA networks do not use SIM cards and each phone under this network is designed to work on that specific carrier’s network. 
  • This means that CDMA users are directly tied to their carrier’s bands, and if you need to switch carriers you must buy a new phone. 


  • GSM is the technology developed to improve the portability of cellular phones worldwide and is probably the most widely deployed technology in the world.
  • GSM or Global System for Mobile Communications technology networks, also known as 2G and was the leap into the future in terms of telecommunications technologies from the analog to the digital world.
  • Phones with this technology only need a change of SIM Card to work and not change the cellular equipment as in the past. 
  • GSM also allowed fast Internet browsing on every device.
  • GSM technology can be used around the world and only a SIM card change is required.
  • GSM phones do not require access to the bands of a specific service provider and this makes them easy to unlock.

Which is better between GSM and CDMA?

One is not necessarily better than the other, but GSM has arguably displaced CDMA technology as a natural evolution of technological science.

GSM technology was the first breakthrough into the digital world in telephony and helped drive many other areas of science and technology.

CDMA has certain benefits that GSM technology had to sacrifice in order to expand, such as privacy.

A phone that works under GSM technology is easier to unlock than a CDMA one, it has to have a SIM card slot and if it does not, it cannot be unlocked to be used with another phone company.

T-Mobile network technology and frequencies

Mobile network operations company T.Mobile has a huge presence in many major countries around the world, with 60 million subscribers in the United States alone and growing.

Keeping its technology constantly updated is vital to stay at the forefront of global telecommunications.

We will start the explanation from the most advanced technology to the least, so you will know in depth the connectivity options offered by T-Mobile.

T-Mobile 5G networks

T-Mobile works with XR or extended range, this network covers the entire country, works well both indoors and outdoors, and is typically faster than 4G LTE networks. It works in the frequency band: n71 of 600 MHz.

T-Mobile’s 5G technology also covers networks known as UC or Ultra Capacity, this connection is great as it works faster than Wi-Fi and works excellent in crowded places. This frequency band is highly compatible with high-tech iPhone and Android models.

It works in the frequency bands n41 of 2.5 GHz, n258 of 24 GHz, n260 of 39 GHz, and n261 of 28 GHz. 

T-Mobile 4G LTE Networks

T-Mobile uses 4G LTE networks and they have a download speed that exceeds 3G networks by a large percentage and is one of the most widely used networks worldwide.

The 4G LTE network works in the frequency range 2 of 1900 MHz, 5 of 850 MHz, 4 of between 1700 to 2100 MHz, 66 which is an extension of band 4 and operates in the same frequency ranges.

T-Mobile 3G networks

They are also known as UMTS and HSPA and they are one of the first voice and data technologies used worldwide, currently, T-Mobile supports this network for navigation and voice.

The 3G network operates on frequency band 4 from 1700 to 2100 MHz and frequency band 2 which operates at 1900 MHz.

T-Mobile 2G networks

T-Mobile supports GSM, GPRS, and EDGE networks, which are part of the second generation of telecommunications networks, and are still widely used despite new advanced mobile network technologies.

This frequency range is known as band 2 which operates at 1900 MHz. In this type of technology, internet data does not work while a call is in progress.
