Quick Answer: Which Is Better CDMA Or GSM?

First, neither GSM or CDMA is technically better; they ultimately provide the same service and the quality of a network depends on the carrier, not the cellular standard used.

Second, GSM phones can be unlocked and switch carriers, whereas CDMA phones are locked to a carrier.

What carriers are CDMA?

In the US, Sprint, Verizon, and US Cellular use CDMA. AT&T and T-Mobile use GSM. Most of the rest of the world uses GSM. The global spread of GSM came about because in 1987, Europe mandated the technology by law, and because GSM comes from an industry consortium.

How do I know if my phone is GSM or CDMA?

Check your phone’s “About” settings.

If you see an MEID or an ESN category, your phone requires CDMA; if you see an IMEI category, your phone is GSM. If you see both (e.g., Verizon phones), your phone supports both CDMA and GSM, and may be either one.

Is CDMA going away?

Sprint will drop ANSI-2000 CDMA by 2023+. AT&T will drop 3G W-CDMA by 2021+. T-Mobile will probably keep 3G W-CDMA going for a few years beyond AT&T. (Their HSPA+42 service performance is good, and they do not have the same spectrum pressure that AT&T has.)

What is the difference between CDMA and LTE?

The main difference between the technologies is that both CDMA & GSM can support cellular and data, whereas LTE can only support data. Therefore, a CDMA/LTE Verizon Wireless phone now has a SIM Card but does not work on GSM Networks such as AT&T.

Can I use a CDMA phone on a GSM network?

T-Mobile and AT&T run on GSM networks. Sprint and Verizon run on CDMA technology. The general rule is that a CDMA phone wont work on a GSM network, and vice versa—they run on different frequencies. However, most new iPhones like the 8 and 8 Plus and some Google Nexus phones CAN run on both technologies.

Is US mobile GSM or CDMA?

Well GSM networks like US Mobile, T-Mobile, and AT&T use removable SIM cards. This means that unlocked phones from other American GSM carriers will work on US Mobile’s network. On the other hand, Verizon and Sprint are CDMA carriers. CDMA carriers don’t use SIM cards and most CDMA phones are locked into their network.

How do I know if my phone is GSM unlocked?

Check the back or on the sides of your phone if it has a slot for a SIM card. If yes, it’s likely GSM capable and should, therefore, work on US Mobile. To avoid uncertainty, check the technical specs. Either just google the name of the phone or check your phone’s serial number.
