Deutsche Telekom turns up HD voice on its 2G network

While most recent hype has been on VoLTE deployments, Deutsche Telekom (DT) is backfilling HD voice service, adding support for AMR-WB on its GSM network this month.

DT has previously turned up HD voice on its 3G UMTS/HSPA-ish network. The carrier notes it is the first one in Germany to support HD on its 2G network.

As standard these days, there’s no extra charge for HD voice calls.
