Is my iPhone 11 GSM or CDMA?

Answered by James Kissner

Let me provide you with a detailed answer to your question about the iPhone 11 and whether it is GSM or CDMA.

To start with, the iPhone 11 model A2221 is commonly known as the GSM-Only or Global Version. This particular model is widely available outside of the United States and Canada. So, if you are located outside of these countries, chances are you have the A2221 variant of the iPhone 11.

Now, let’s discuss the differences between GSM and CDMA. GSM and CDMA are two different cellular network technologies used by carriers worldwide. GSM (Global System for Mobile Communications) is the more prevalent technology worldwide, while CDMA (Code Division Multiple Access) is more commonly used in the United States.

The A2221 variant of the iPhone 11 is primarily designed for GSM networks. It supports a wide range of GSM bands, making it compatible with carriers globally. This means that if you are using a GSM-based carrier, such as AT&T or T-Mobile in the US, the A2221 variant will work perfectly fine.

However, it’s important to note that the A2221 lacks support for legacy 3G CDMA networks and FDD-LTE Bands 14 and 71, which are used by some US carriers. This means that if you are using a CDMA-based carrier, such as Verizon or Sprint in the US, the A2221 variant might not provide full network compatibility.

In practical terms, this means that if you are using a CDMA-based carrier with the A2221 iPhone 11, you might experience limitations in terms of network coverage and connectivity. It’s always recommended to check with your carrier if you are uncertain about compatibility.

To summarize, the iPhone 11 model A2221 is primarily a GSM-Only or Global Version. It works well with GSM-based carriers worldwide, but may have limited compatibility with CDMA-based carriers in the US due to the lack of support for certain CDMA networks and bands.

I hope this detailed explanation helps clarify the GSM or CDMA compatibility of your iPhone 11. If you have any further questions or need additional information, feel free to ask!
