There may be a few settings you would need to check if your 5G service is not working.
- Check that the preferred network type is “5G (preferred)/4G/3G” – this ensures that if 5G is available, it will lock into that signal, and if it is not, it will lock onto the 4G network.
- If there is a “5G network mode” setting, set it to “auto-select”. Please note that settings may differ by phone model and manufacturer.
