2G GSM network has been shut down in some countries and more and more telecommunication carriers are beginning to retire their 2G network towers, like AT&T’s 2G network fully retired by January 2017 and T-mobiles 2G GSM networks by 2020 in favor of their faster 3G and 4G networks. So “2G sunset is coming, what should I do?” Here are the top things you need to know:

What is the 2G sunset and why does it matter?

Carriers are looking to repurpose the towers in their network for 3G and 4G service that delivers much faster speeds and larger bandwidth capable of handling things like video conferences, streaming and other large data packets. So many carriers are taking down their 2G towers.

What will the sunset effect 2G customers?

If you ask “should I worry about the 2G sunset?” of course the answer is Yes. AT&T was one of the first to phase out all of its 2G GSM wireless service since January 1, 2017. Several other carriers have also announced plans to eventually sunset 2G. See the carrier 2G shutdown list.

What should I do?

In order to prepare effectively for the 2G sunset, you need to understand what carrier your 2G devices are using and how long that carrier is planning to support them. Contact that provider to understand their roadmap for the 2G sunset and to ensure you are purchasing for an appropriate timeframe on that 2G GSM network. If your carrier has no 2G sunset plan yet, you can keep purchasing GSM network product. If your carrier already has the sunset plan, upgrade to 3G products soon.
