Voice call through data quality is very very poor.
2G gives a very clear voice and is the preferred and recommended in the ITU standards.
Technology of 2G and 3G is different.
That is why any mobile phone normally has both true voice and data capabilities for the case of smart phones.
The antennas are also different for 2 and 3/4G
What about WhatsApp, Viber and FaceTime? Sometimes, my WhatsApp calls sound better than my regular voice calls especially on Safaricom! Isn't WhatsApp reliant on 3G/4G? [Though to save data, I often use WhatsApp when I am on a good wifi]
