    2G and 3G Sunsets: When They’ll Happen and How to Prepare

    Carriers around the world are shutting down their 2G and 3G networks. Here’s how to make sure your business is ready.

    Billions of IoT devices rely on 2G and 3G cellular networks. These solutions offer IoT manufacturers an affordable way to keep devices connected anywhere in the world—indoors, outdoors, or on the go. But the technology is decades old, there are better solutions available, and there’s only so much bandwidth to go around.

    And that’s why over the next few years, these networks are shutting down for good.

    1. Why are carriers shutting down their 2G and 3G networks?
    2. How should IoT businesses prepare for the sunsets?
    3. When is the sunset happening?

    Some carriers have already sunsetted their 2G and 3G networks, pulling the plug to make room for newer cellular networks like 4G and 5G. Most other operators have at least made plans to shut them down. Thankfully, they’ve made these plans public—so you won't be caught unaware.

    In this article, we’ll share when 2G and 3G networks are shutting down around the world, as well as what your business can do to prepare. But first, let’s look at why this is even happening.

    1. Why are carriers shutting down their 2G and 3G networks?

    Haven’t cellular carriers heard the phrase, “if it ain’t broke, don’t fix it”? 2G and 3G networks work just fine for most IoT applications. So why wouldn’t cellular providers just keep them around?

    It all comes down to supply and demand.

    2G and 3G technologies have already gone through extensive updates to increase their lifespans and get every last bit of use from their infrastructure. But carriers each have a limited range of radio frequencies they can dedicate their networks to. And the demand for 4G, 5G, LTE-M, and NB-IoT will only increase in the years to come.

    Most 2G networks based on GSM use 850–1800 MHz or 900–1900 MHz bands. And 3G networks use bands between 850–1900 MHz or 900–2100 MHz. More advanced cellular technologies could use these same bands to provide higher data throughput and more valuable functionality. And all around the world, the opportunity these newer networks present is outgrowing the demand for continuing to support 2G and 3G infrastructure.

    So with that in mind, it’s crucial that IoT manufacturers know when the sunset is happening and what they need to do before then.

    2. How should IoT businesses prepare for the sunsets?

    The last thing you want is to be using 2G or 3G networks when a carrier you rely on shuts their network down. Even if you still have years according to an operator’s current plan, you want to be proactive, not reactive. Here’s how to make sure you’re ready.

    Evaluate your current IoT devices

    Some of your devices may depend entirely on 2G or 3G connectivity. Others may simply use it as a fallback when other options like 4G or LTE-M aren’t available. You need to take inventory of every device that relies on this technology, assess which deployments and customers will need to make a transition, and identify the specific carriers your devices use.

    You may simply be able to change your cellular service to a newer technology your devices are already compatible with. Or disable the functionality that searches for 2G and 3G networks. In many cases though, your devices may need significant upgrades to continue operating.

    Know the dates that affect your deployments

    Some carriers will continue supporting their 2G and 3G service for years. Some will make an immediate transition and sunset their entire service on a specific date, and others will gradually throttle down their 2G/3G service as they convert the available RF spectrum to other services. You don’t have to know what every carrier is doing. But you need to learn everything you can about how the carriers your business depends on are handling the transition.

    Create a migration plan

    Once you know the devices that need to switch and the dates they need to switch by, you’ll need to create a timeline for migrating to another solution. This may require coordinating significant updates and retrofitting with your customers. Or it could be a matter of planning out a transition to another service with your carriers. Your migration plan will depend on your business’ unique circumstances.

    3. When is the sunset happening?

    There’s actually no universal date for when carriers will shut down their 2G and 3G networks. Each Mobile Network Operator (MNO) has to decide when it makes the most sense for their business, based on local demand, their goals, and what they’re capable of. Many carriers have already phased out 2G service, and several plan to end 3G by the end of 2022.

    Since you could have IoT deployments anywhere in the world, here’s a complete list of planned 2G and 3G sunsets by country and provider.

    Africa is still behind other regions when it comes to refarming the spectrum to accommodate LTE and there have been no concrete dates for 2G and 3G shutdowns. However, in certain countries and networks, it has been reported that no 2G or 3G service is currently available.

    East Asia is leading the way regarding switching off 2G networks with some other Asian countries following. In certain countries in the region, such as Japan, Macau, Singapore and South Korea, there is no 2G available at all. In addition, several network operators have already planned for future 3G shutdowns.

    In some European countries and networks, it could be the case where 2G may even outlive 3G. For example, Norwegian MNO Telenor announced 3G switch-off in 2020 – five years before 2G. Likewise, Vodafone has announced it is to phase out 3G networks across many European countries in 2021 and 2022.

    Except for Vodafone New Zealand, most large operators have already switched off 2G service in Australia and New Zealand. On the other hand, there has been no plan for a massive 3G switch-off in the region.
