The recent announcement from AT&T that they will shut down their 2G network latest year-end 2016 has been discussed a lot lately. It is safe to say that mobile operators in developed markets will continue transitioning their handset users and networks towards 3G and 3G LTE. But mobile operators in general have a growing number of M2M terminals in their networks and they know that over 90% of them are using 2G modules today. Many of them are recently deployed and expected to run without intervention for maybe another five to ten years. Going there, changing SIM, terminal or in worst case the entire device is a very costly thing to do. This is probably why mobile operators in general don’t talk about when they plan to terminate their 2G networks. And I don’t think we will see many announcements like the AT&T one for the next few years, especially not in Europe. Also, let us not forget that many operators in developing countries only have 2G so it will definitely be around for quite some time.
Over the air provisioning of SIM-cards will solve some of the 2G sunset problems but if you need another module in your terminal it will obviously not help. One or two operators in a market, or why not an MVNO, can gather all the 2G terminals and continue service them until the bitter end. The remaining operators would lose some clients but free themselves to go wild on 3 and 4G.
