Hello,

I have a Sierra Wireless MC7430 modem which does not support CA on bands B3 + B40. This is what Airtel uses contrary to Jio which uses B40+B40. Anybody aware of modem which support B3+B40?

Here is what MC7430 supports:
Code:
AT!LTECA?

LTEB1: B8, B18, B19, B21, 
LTEB3: B5, B7, B19, B28, 
LTEB5: B3, B7, 
LTEB7: B3, B5, B7, B28, 
LTEB8: B1, 
LTEB18: B1, 
LTEB19: B1, B3, B21, 
LTEB21: B1, B19, 
LTEB28: B3, B7, 
LTEB38: B38, 
LTEB39: B39, 
LTEB40: B40, 
LTEB41: B41,

I noticed that Sierra Wireless MC7430 is picking up 2xCA on Airtel.

Here is the connection dump from Rooter,
