Samsung Galaxy A22 5G never shows 5G

My 'Samsung Galaxy A22 5G' never shows "5G" on its status bar, despite being where 5G coverage is proven (checked on another 5G smartphone of mine). It only shows "4G+". https://www.gsmarena.com/samsung_galaxy_a22_5g-10873.php lists this phone as having 5G bands: 1, 3, 5, 7, 8, 20, 28, 38, 40, 41, 78, 79 SA/NSA/Sub6 Entering my phone's IEMI into https://www.imei.info only shows the following: IMEI.info: LTE-FDD: 800, 900, 2100, 2600 and IMEI.info: LTE-TDD: 2300, 2500, 2600: I verified that its 'Network mode' is set to 5G/LTE/3G/2G (auto connect). I also tried resetting its network settings via General management > Reset > Reset network settings. Still, it only shows 4G+. It never shows 5G. Any idea why?
