VONR not working and Network issue

[Anjan1234]

I've been using an A55 for the past two months. Its 5G frequently downgrades to 4G in certain areas, leading to very slow internet speeds. However, my other phones, like Oppo Reno 13 and Vivo V40 consistently show 5G in those same locations with no internet speed issues. Additionally, VoNR never works on my A55, while it's clearly visible on my other handsets using the same SIM card. These problems have persisted across both One UI 6 and One UI 7. Please address these issues.
