No. Poco X3 Pro has the Qualcomm Snapdragon 860 processor which does not support 5G.
Asked From experts
The Poco X3 Pro is probably the best phone for gaming at its price. It has a large, well-specced screen, loud stereo speakers, and its Qualcomm Snapdragon 732G processor handles titles such as Fortnite far better than the Snapdragon 665 and Exynos 9611 phones you might buy for the same cash. It's simply miles ahead.

Snapdragon 860, liquid cool technology, and ufs 3.1 need I say more
