One major distinction between GSM networks and CDMA networks is that the former allows you to make voice calls and transmit data at the same time, while the latter does not. The distinction is becoming less important and will be entirely irrelevant sooner rather than later more on that below. Different carriers have different timelines for this, but Verizon is taking concrete steps to begin transitioning CDMA devices off of the network at the end of — eventually moving all devices to the HD Voice LTE network.

This has implications for people with older phones who want to switch carriers. They will also no longer be able to provide such a device to activate on an existing line or swap one such device for another. However, customers with these devices will still be able to suspend and resume service, change their phone number, upgrade to compatible 4G or 5G devices and activate new lines for 4G or 5G devices.

While the CDMA network will remain available as-is until that date, any service requests related to CDMA devices may receive limited support after the end of Customers are encouraged to upgrade to newer technology.

The next step to offer further improvements is 5G , which is rolling out now. For U. Today, all carriers support voice over 4G and are in the process of installing 5G, which is intended as a single global standard called 5G-NR. If you are still using a 2G or 3G phone, consider upgrading and replacing it with a 4G or 5G phone.

Verizon has already shut down its CDMA network. Meantime, the remaining networks are being truncated to levels designed for devices like electric meters and vending machines, so any remaining 2G and 3G reception and call quality is likely to be poor in advance of formal turnoffs.

While 5G may have higher speeds and low latency, it still has a significant number of obstacles to overcome before it can become the worldwide universal network standard.

Ultimately, the goal to shoot for with 5G is universal compatibility, but many restrictions are working against that goal including software limitations and restrictive permissions that make this difficult to accomplish. At least for now, consumers can feel some relief as even lesser-known brands like ZTE or Nubia support LTE networks from major carriers. Galaxy Buds 2.
