3G has been shut down in several countries to free up frequencies. 2G was also shut down in several countries, it seems to be still up in most european countries with shut downs being scheduled in the next few years up to 2030.
In Norway, Telia shut down 2G in 2025, but Telenor is holding out until the end of 2027.
In Sweden, Telia is holding until 2027, and all other telcos have already switched it off.
France is shutting down 2G this year.
So the 2G shutdown is a real thing.
Is how it should be country wide in my opinion. Way too many towers up everywhere just so xyz company can get coverage there. Leaving no 1 company to have the "best" coverage.
