Not sure if this is  a phone issue or with the network, I am having some issues with VOLTE  on my S8. Hoping someone can point me the correct way.


Constant dropping to H+ while travelling and does not go back to 4G unless reboot or turn off and on data at 4g supported areas. VOLTE sign dissapears but still on 4g, calls unable to call  in and call out as the VOLTE sign is not lighted. Need to reboot or turn off and on data and it goes back to normal.


Anyone having this issue as well ?
