Key Features of GSM:
- Uses SIM cards to authenticate users
- Supports international roaming
- Offers better coverage and capacity
- More widely supported by mobile devices
CDMA (Code Division Multiple Access)
CDMA is a wireless communication technology that uses a different approach to manage multiple users on the same frequency band. Instead of using TDMA or FDMA, CDMA uses a spread-spectrum technique to transmit data. CDMA networks are commonly used in North America and parts of Asia.
Key Features of CDMA:
- Does not use SIM cards; instead, uses a unique identifier stored in the device
- Offers better security and resistance to interference
- Supports faster data speeds
- Less widely supported by mobile devices

What is the difference between GSM and CDMA networks?
The primary difference between GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access) networks lies in the technology used to connect calls and transmit data. GSM networks use a time division multiple access (TDMA) method, where each call is assigned a specific time slot. In contrast, CDMA networks use a spread-spectrum technology, where all calls are transmitted simultaneously, and the receiver filters out the desired signal.
This difference affects the way phones operate on these networks. GSM phones use a SIM card to store subscriber information, while CDMA phones typically store this information directly on the phone. As a result, GSM phones are generally more versatile and can be used on different networks by simply swapping the SIM card, whereas CDMA phones are often locked to a specific network.
Is the Verizon iPhone 6 Plus a GSM or CDMA device?
The Verizon iPhone 6 Plus is a CDMA device, as it was designed to operate on Verizon’s CDMA network. However, it’s essential to note that this iPhone model also supports GSM networks, making it a dual-mode device. This means that the phone can work on both CDMA and GSM networks, depending on the region and the SIM card used.
Verizon’s iPhone 6 Plus model (A1522) supports various frequency bands, including CDMA, GSM, and LTE. This allows users to roam internationally and use their phone on different networks, including GSM-based networks. Nevertheless, the phone’s primary functionality is still tied to Verizon’s CDMA network.
