That's because Samsung not provide volte 4g upgrade completely it will 4g ready phone on 2'nd Sim both Sim slots are NOT Compitable with complete Volte 4G....that what I felt and realise just because I use 2 BSNL Sim on 2 different phone and also facing issue with Wi-Fi 5ghb band may having same issue on galaxy m31 on Jio fiber network.. If anyone's can known how to fixed plz tell me unless all 4 years security update and android update provided by compny that means this phone now won't be get any updates and useless within year

Dear all, I'm using samsung s23 the Volte is not working on BSNL 4g whereas the same sim I tried on Vivo and Moto the volte is works perfectly fine , and also tried other samsung models. S23 ultra and M35 volte won't works, did all workaround which shared on community and you tubers doesn't works, so samsung needs to be fix on next patch update. Experts pls forward this issue to technical support desk to address the issue on next patch update for all samsung model so that we can use BSNL 4G with volte. Thanks for your understanding 🙏 namaste
