Bsnl 4g Volte is not working on Galaxy devices

[IllayarajaC-S23-User]

Dear Samsung Team, I am using the Samsung S23, and I have noticed that VoLTE is not working on BSNL 4G. However, when I use the same SIM in Vivo and Moto devices, VoLTE works perfectly. I have also tried other Samsung models, such as the S23 Ultra and M35, and VoLTE doesn't work on them either. I have followed all the recommended solutions shared by the community and YouTubers, but none of them have resolved the issue. I kindly request that Samsung addresses this problem in the next patch update. Please forward this issue to the technical support desk so that the necessary fixes can be implemented for all Samsung models, enabling us to use BSNL 4G with VoLTE. Thank you for your understanding. Kind regards.
