I have had to make a similar purchase decision and went for the new Samsung M33. This is a 5G phone, has Android 12 already installed, 8Gb memory and 128GB storage - still showing 83GB after OS & Apps installed. Has dual SIM slots on the SIM tray plus another separate slot for a SD card. Samsung say they will provide 2 further Android updates & 4 years of security updates. I found their migration App worked well moving files & apps from my Moto phone. Priced at B6990 from Samsung Shop on Lazada.
Week 6 and all working as it should, fast responses on screen & battery averaging over 2 days. US usage you would have to check, I had a query & an English speaking Samsung rep phoned me back within 90 minutes.
