Most of the mobile device manufactures don’t tell you of supported 4G LTE CA ( Carrier Aggrecation) combinations on their hardware specifications but these are very important to know because they are the key factor to get best performance on your device and network.
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.
