When it comes to understanding mobile networks and the type of technology your carrier uses, it can be a bit of a maze. If youโre a MetroPCS user or looking to become one, you might be asking yourself, โDoes MetroPCS use GSM or CDMA?โ Itโs important to know this information as it influences many aspects like device compatibility, quality of service, and international roaming.
TL;DR: MetroPCS uses GSM technology as it is now part of the T-Mobile network.

Comparing GSM and CDMA
Before we go further, letโs clarify what GSM and CDMA mean. They are both multiple access technologies, allowing many users to share the same frequency band. GSM stands for Global System for Mobile communications, while CDMA stands for Code Division Multiple Access.
- GSM: This technology is more widely used internationally. GSM phones use a SIM card, making it easier for users to switch phones by simply transferring the SIM card.
- CDMA: Predominantly used in the US, CDMA phones donโt traditionally use a SIM card. Instead, the phoneโs information is stored directly on the phone itself.
| Feature | GSM | CDMA |
|---|---|---|
| Technology | Time Division Multiple Access (TDMA) | Code Division Multiple Access |
| Data Speed | Up to 384 kbps (EDGE); Up to 42 Mbps (HSPA+) | Up to 2 Mbps (1xRTT); Up to 3.1 Mbps (EV-DO Rev.A) |
| Frequency Bands | 850/900/1800/1900 MHz | 850/1900 MHz |
| Sim Card Usage | Yes, GSM phones require a SIM card | No, CDMA phones are typically tied to a particular carrier and do not use SIM cards for 2G and 3G services. However, for 4G LTE, SIM cards are used. |
| International Roaming | More widely used internationally, hence better for international roaming | Less widely used internationally, hence may have issues with international roaming |
| Call Quality | Generally good, but can vary based on factors like signal strength and interference | Generally excellent, as CDMAโs technology tends to handle interference and signal strength issues better |
| Market Share | More widely used globally | Predominantly used in the United States by carriers like Verizon and Sprint |
| Network Switching | Easier to switch networks as it involves just swapping SIM cards | More difficult to switch networks as the device is typically tied to a specific carrier |
MetroPCS and GSM
The history of MetroPCS is intertwined with these two technologies. Originally, MetroPCS was a CDMA carrier when it was first established. However, things changed after it merged with T-Mobile in 2013.
Post the merger, MetroPCS transitioned to GSM and LTE, which are globally more recognized and widely used technologies. In fact, MetroPCS (now known as Metro by T-Mobile) fully phased out its CDMA network in 2015. So, if youโre currently a MetroPCS user, youโre using a GSM-based service.
Why GSM is a Good Thing
There are several reasons why MetroPCS using GSM is beneficial for you:
- Device Compatibility: With GSM being a global standard, a wide array of devices are compatible with your MetroPCS service. This means greater freedom when choosing your preferred device.
- SIM Card Use: The SIM card functionality allows for easier transition between devices. You simply need to move your SIM to a new device to get it up and running.
- International Roaming: Given the extensive international adoption of GSM, if youโre a traveler, your MetroPCS phone is likely compatible with many networks worldwide.
- Flexibility: As we mentioned earlier, GSM phones use SIM cards. This makes it easier to switch phones, transfer contacts, and retain your information when upgrading your device.
- Wide Variety of Devices: Because of GSMโs popularity, phone manufacturers offer a vast array of GSM-compatible devices. From high-end smartphones to budget-friendly models, the choices are endless.
The Shift from CDMA to GSM
As noted, MetroPCS initially used CDMA but shifted to GSM after the T-Mobile merger. This shift is reflective of a broader industry trend. Many carriers, even those traditionally on CDMA like Sprint, have started to transition to GSM and LTE.
The reason for this shift is largely about universal appeal and advanced technology. GSM is more widely accepted around the world, which allows users greater flexibility in using their devices internationally. Furthermore, GSMโs SIM card feature is a user-friendly way to manage devices and personal information.
MetroPCS Alternatives
While MetroPCS, or Metro by T-Mobile, uses GSM, there are other carriers you may consider if youโre looking for a CDMA network. Major carriers like Verizon and Sprint use CDMA technology, though itโs worth noting that most carriers are now moving towards the global standard of GSM and LTE.
If you have an old MetroPCS device that is CDMA based, I recommend upgrading to a GSM device. While MetroPCS transitioned to GSM, they continued to support their CDMA network until June 21, 2015. After this, CDMA devices could no longer be used on MetroPCS.
Conclusion
In conclusion, itโs clear that MetroPCS uses GSM, not CDMA. This move, initiated by their merger with T-Mobile, ultimately provides more advantages to MetroPCS users. With GSMโs global acceptance, wider device compatibility, and SIM card convenience, itโs clear why MetroPCS and many other carriers are opting for GSM.
Remember, the key to a satisfactory carrier experience lies in understanding your unique needs and how your carrierโs technology aligns with them. So, whether youโre a globetrotter needing extensive international coverage or a tech enthusiast who frequently upgrades devices, MetroPCS and its GSM technology have much to offer.
