Portugal will keep it too. Dumb phones are still being sold that are 2G only. Not just that, but “landlines” are still being offered that are really a 2G phone restricted to work only in the vicinity of a home that's not (yet?) covered by actual landlines. It's also used by emergency services. It's considered a technology of last resort, and the service provider that wins the concession to provide it, with 100% coverage of a given area, probably finds it useful that it can meet the conditions with such tech. 3G has already shut down.
