Sim 2 no volte

[Thenaxios]

My rog phone 7 has no volte option on sim2. Is this standard?

It works for globe.

Thanks for the reply. Is the VoLTE connection stable? No drops? How about WiFi Calling?

I havent tried wifi calling but volte is stable.

Thanks. I have an ROG 5 and sadly, VoLTE seems to be working at first but drops after a few hours of runtime. The phone needs to be restarted for VoLTE to function normally. Same with WiFi Call.

P.S. I'm using Globe postpaid on sim 2, Smart Prepaid on sim 1. Only globe has VoLTE.  I hope ASUS will support VoLTE with Smart soon. My POCO X4 GT supports VoLTE for Smart and Globe right out of the box.
