3G is Sunsetting

Prepare Now for a Smooth Transition to LTE

For system integrators, service providers, manufacturers, and other companies whose businesses involve cellular-connected business equipment, 3G sunsets aren’t a crisis—but a call to action. Cellular carriers are gradually ending support for 3G networks, leaving LTE as the only option.


You need to act now to determine which devices these sunsets affect and how to update or replace them as quickly and painlessly as possible. That’s where Telit comes in.

Steps to Prepare for 3G Sunset

  1. Assess your 3G deployments (which devices, how many, where)
  2. List the 3G speed and throughput needs for your 3G terminals, gateways, modems, and devices.
  3. Determine which Telit module series your devices are running.
  4. Identify any voice-capable LTE devices that run on anything other than Voice over LTE (VoLTE).

3G Sunset Dates

Cellular technology keeps evolving.

That’s why the 2G network sunset began a few years ago. And it’s why the 3G sunset is happening now, with Verizon shutting down all 2G and 3G networks by the end of 2019, other carriers in 2021 and AT&T shutting down by 2022.


Carriers are already terminating new 3G activations and reducing 3G service availability on CDMA, GSM, and HSPA networks.

Why Now?

For carriers, sunsetting 3G opens up the available spectrum necessary to operate more cost-effective 4G and 5G LTE networks.

For businesses, 3G sunsets mean challenges in the short term as you’ll be pressed to transition fully to LTE before service is disrupted and ultimately terminated. But over the long term, the transition will enable you to run your IoT and other devices on faster, more efficient 4G and 5G LTE networks.

LTE Devices on 3G Networks? That's a Problem.

Numerous consumer and business applications still rely on 3G networks for voice communication, including alarm panels, wearables, elevators, and other IoT devices. The devices themselves may be LTE, but in many cases, they’re running voice on 3G networks, which means voice service will be disrupted and ultimately ended with the 3G network sunset.

To avoid any surprises, businesses need to identify every 3G device and connection and build a roadmap to LTE. For voice applications, that likely means migrating to Voice over LTE (VoLTE) to improve voice quality and alleviate future service problems.
