While it is essential to choose the right mobile phone service plan from the service provider of your choice, it is also important to choose the right service provider in the first place.

Today, we will take explore the different technologies that wireless service providers use to help you differentiate yourself. In other words, we will be checking out; GSM vs. EDGE vs. CDMA vs. TDMA

General Findings: GSM vs. EDGE vs. CDMA vs. TDMA

GSMEDGECDMATDMA
Information stored on SIM cards.Based on GSM.May use SIM cards.2G system.
Switching phones means only switching cards.Three times faster than GSM.Provider stores information.Predates GSM.
Most widely used, especially internationally.Used by AT&T and T-Mobile.Can’t change phones without provider approval.No longer in use.
Switch SIM cards to use phone in other countries without roaming. Used by Sprint, Virgin Mobile, and Verizon Wireless. 

The two main mobile phone technologies, CDMA and GSM, have been incompatible for years. This incompatibility is the reason why many AT&T phones do not work with Verizon and vice versa.

EDGE is the faster version of GSM and TDMA is obsolete. Therefore, TDMA is no longer a viable option. It effectively boils down to GSM and CDMA, with GSM overtaking CDMA in terms of ease of use for users and consumers.

Speed: GSM vs. EDGE vs. CDMA vs. TDMA

3G network.Three times faster than GSM.3G network.2G system.
Max speed of about 7.2 Mbps. Only about 1 Mbps.No longer available.
Average speed of 2.11 Mbps.

GSM and CDMA are both 3G networks, but between the two, GSM is the faster option. CDMA shows an effective download speed of around one megabit per second, while GSM claims speeds reach up to 7 Mbps. In testing, the practical speed of GSM approached 2.11 Mbps, which is twice as fast as CDMA.

EDGE is three times faster and swifter than GSM and is based on this standard. It is designed to adapt to media streaming on mobile devices. AT&T and T-Mobile have EDGE networks.

Overall, EDGE stands out when it comes to speed.

Ease of use: GSM vs. EDGE vs. CDMA vs. TDMA

Uses SIM cards to store user data.Works similarly to GSM.Doesn’t use SIM cards.Unavailable.
Transferring to a new phone means only swapping the SIM card. Carrier must release or transfer user data to a new phone. 
Better for international use.

GSM network service providers place customer data on a removable SIM card. This approach makes it easier to change phones. Remove the SIM card from the old phone and insert it into the new one.

GSM technology is prevalent in Europe. Combine that with a mobile phone with a removable SIM card, and you have a phone you can use when visiting abroad with a change of SIM card.

CDMA phones may or may not use SIM cards. User informations are stored with your service provider, who must give permission to change phones.

CDMA phones must be programmed with all the carriers you use. When you change providers, the phone must be reprogrammed for that service provider, even if it is an unlocked phone.

Overall, GSM is more comfortable for users to as it is user-friendly, and roaming is enabled for travellers.

Service Providers: GSM vs. EDGE vs. CDMA vs. TDMA

GSMEDGECDMATDMA
Providers include T-Mobile and AT&T.Same as GSM.Providers include Sprint, Virgin Mobile, and Verizon Wireless.Incorporated into GSM.
More popular internationally.

GSM is the world’s most widely used mobile phone technology, popular in the United States and around the world. Cellular carriers T-Mobile and AT&T, as well as many smaller cellphone providers, use GSM for their networks.

GSM is the most popular mobile technology in the United States and the most important in other countries. China, Russia and India have more of GSM phone users than the United States. It is common for GSM networks to have roaming agreements with foreign countries, which means GSM phones are a good option for foreign travellers.

EDGE is an advancement of GSM, so it has the same availability as the previous standard.

CDMA competes with GSM. Sprint, Virgin Mobile, and Verizon Wireless use standard CDMA technology in the United States, as do other small mobile service providers.

Since 2015, all US carriers have had to unlock customers’ phones after fulfilling their contracts. Even if you unlock the phone or buy a new unlocked phone, it is a GSM or CDMA phone, and one can only use it with compatible service providers. However, an unlocked phone gives you a wider choice of service providers. You are not limited to just one.

TDMA, which precedes the most advanced standard in GSM technology, is integrated into GSM. The major US providers of TDMA cell phone services, which used to be a 2G system, are no longer in use.

Conclusion

The quality of telephone service has nothing to do with the technology used by the provider. The quality depends on the network and the structure of the service provider.

There are good and not very good networks with GSM and CDMA technology. You are more likely to have quality issues with small networks than with large ones.
