Ernsthaft, #O2 muss mal #AMRWB und #WiFicalling sowie #VoLTE & #Vo5G konsequent ausrollen!

I mean, I don't expect a #Tablet to have good #Audio quality.

• Frankly I'd be content with #Codec2-level #AMR since no carrier properly implements #AMRWB anyway. Everyone who even halfasses #AudioQuality will plug in a headset anyway...

But being able to just chug in a #SIM and test it by calling it is something people do need rather often!

• Even if it's just for a few calls like booking a data package on the go!
