The short answer is yes. Globally, 2G and 3G will disappear in the coming years, and in some countries they have already disappeared. It is inevitable, since the frequencies currently used by 2G and 3G will be necessary for 5G (remember that NB-IoT is part of the 5G ecosystem). Most operators have already announced a specific date for the shutdown of 3G networks. For example, Movistar in Spain will turn off 3G in 2025. Some have also set a date for the turn off of 2G, although later than for 3G, given the high implementation of 2G (GPRS) in the field of industrial M2M. It must be remembered that legacy 2G (GPRS) or 3G modems ARE NOT compatible with 4G, and it would be necessary to replace them in the event of the GPRS networks being turned off.

Those responsible for the projects are recommended to take this circumstance into account when choosing the solutions to install. Tellink has Lighting Remote Management solutions in Panels with 2G modems, and others with dual 2G+4G modems. Tellink always recommends the use of dual 2G+4G systems, to avoid the possible risk of shutting down 2G networks, but the cost is higher. The decision ultimately rests with those responsible for each project.
