We are not quite sure why manufacturers are so reluctant to publish this information but one of the reason could be that it is quite complicated. Many devices have carrier policy which will tell the modem to limit combinations because if device supports over 128 combinations the modem will slow down. Therefore it is better to limit CA combinations per mobile phone operator. ...
