Are intraband CA (2300Mhz) useless?
Depends on the time when you use it. Think of these bands as highways. Intra means same highway, inter means different highways. So when your phone uses intra, it means you are using different lanes from same congested highway, so your speeds will be lower.
I said depends on time, coz "usually" at night, congestion is relatively lower than day time.
Regarding phones with interband CA, the o e suggested above or G52 from
Moto is also a decent option. I usually get around 110-115mbps at night on 2CA interband on Airtel when CA is not disabled.
