Does the POCO X7 support carrier aggregation?

The POCO X7 supports 4G carrier aggregation (in-band continuous, in-band non-continuous, and inter-band carrier aggregation), 4G+ and dual 4G.  
Carrier Aggregation (CA) refers to a technique used in mobile networks to combine multiple frequency bands (or carriers) to increase the overall data bandwidth and improve network performance. This process allows mobile networks to deliver higher speeds, better connectivity, and more efficient use of the available spectrum, especially in 4G LTE and 5G networks.
In 4G LTE networks, carrier aggregation supports up to 5 carriers (i.e. 100MHz bandwidth), while in 5G networks, the capability of carrier aggregation is further enhanced to support more carrier combinations, especially the aggregation of low-frequency (such as Sub-6GHz) and high-frequency (such as millimeter wave, 24GHz and above) spectrum.
