Verizon global vs. CDMA-LTE – Which one to use and what are the differences?

Individuals seeking enhanced coverage are opting for the network that best suits their location, and this is why a significant number of people have already chosen the Verizon network. Furthermore, Verizon has crafted multiple packages to cater to the diverse needs of users. Selecting the appropriate network type is crucial for achieving better performance and outcomes.

For those contemplating the distinctions between network types, particularly global and LTE/CDMA, we have incorporated the preferred network type into this article.

Before delving into the core content, let’s outline the steps for those wishing to choose the right network type:

  1. Navigate to the settings app on your phone.
  2. Access the “network and internet” section.
  3. Click on the tab labeled “mobile network” to view available options.
  4. Choose the network type that aligns with your preferences.
  5. Save the settings based on your current location.

Even if international carriers are automatically selected, you can always modify the settings using the Connection Manager app. In the following section, we’ve provided a step-by-step guide:

  1. Open the Connection Manager app.
  2. Locate the network settings in the dropdown menu within the app.
  3. Choose the network type that suits your requirements.

What is the difference between Verizon Global vs CDMA/LTE?

In the section below, we have thoroughly explained the difference between Verizon Global as well as CDMA/LTE:

Verizon Global

Opting for the Global network type is an excellent decision if you require top-notch service and signals across all your locations. By choosing this option, you can seamlessly connect to the latest network technology. In instances where the selected technology is unavailable, the device will make efforts to connect to alternative technologies and network configurations.


This configuration proves beneficial for individuals experiencing network and signal challenges in specific locations. Typically, such issues arise in areas where various network types operate concurrently. However, selecting LTE/CDMA settings on Verizon ensures a consistent and reliable signal quality.

It’s important to note that these problems often arise in locations where Verizon operates different network types independently. In these instances, utilizing LTE/CDMA settings ensures a dependable and satisfactory signal quality.

LTE/CDMA is a 4G network setting, introduced with Release 8 of 3GPP in 2009. Since then, LTE has undergone multiple enhancements, such as LTE-Advanced and Pro. One notable enhancement is carrier aggregation, enabling a single user device to connect to multiple channels for higher data speeds. The following peak speeds can be achieved with LTE, the 4th generation mobile network:

  • LTE – up to 300 Mbps in the downlink
  • LTE Advanced – up to 1 Gbps in the downlink
  • LTE Advanced Pro – up to 3 Gbps in the downlink

While these peak speeds are network-generated, the actual speeds on a single device are influenced by the radio signal’s nature and concurrent network usage. Voice over Long Term Evolution (VoLTE) utilizes the packet-switched part of the mobile network for calls and text messages.

In conjunction with the 4G core network EPC, the IMS (IP Multimedia Subsystem) enables voice calls and text similar to other data services. The fallback CSFB (Circuit-Switched Fallback) allows the mobile network to switch on and off for calls in areas lacking voice over internet protocol. Calls and text messages are facilitated by 2G or 3G mobile networks due to their circuit-switched capability.

Turning to CDMA, the migration from 3G to other 2G technologies preceded the CDMA2000 track. The standard CDMA2000 1xRTT or IS-2000 succeeded the old IS-95 standard, offering 3G mobile services. Upgrading from IS-95 to CDMA2000 is seamless due to backward compatibility. Both use a carrier bandwidth of 1.25 MHz and support both circuit-switched and packet-switched communication.

EVDO, employed in CDMA2000, enhances data speeds similar to HSPA in UMTS networks. EVDO achieves peak downlink and uplink speeds of up to 14.7 and 5.4 Mbps, respectively.

What about LTE/GSM/UMTS?

When you travel to different places, you’ll encounter various network types. If you encounter signal problems in a specific location, consider switching to a GSM/UMTS connection type. When journeying to foreign countries, it’s advisable to utilize the Global System for Mobile Communications (GSM). As for UMTS, it stands for the Universal Mobile Telecommunications System and encompasses 3G internet settings.

Conclusion – Which one should you use?

You have the flexibility to use either network type when traveling or residing in the United States. Commonly, smartphones in the U.S. operate with CDMA and LTE network types. Conversely, when venturing outside the U.S., the network style typically shifts to LTE/GSM/UMTS (often automated with Global network configuration). There isn’t a definitive answer regarding the optimal network type to use.

For those prioritizing battery conservation, it’s advisable to consider a network type with better coverage, ideally the CDMA/LTE combination. When traveling internationally, adjusting the global network type on your Verizon phone to align with the destination country is recommended. Verizon acknowledges the need for a two-tier network type to cater to diverse requirements and provides accordingly.
