Hey @New-User9


Try looking in...




Sim Card Manager.

Dual Sim Always On.


Are both sim cards on the same network or different networks.


I ask as if they are both on the same network you may need to ask your network if they support surfing while making or receiving a call.


I have two different network sim cards in my phone so I'll check how mine behaves for you.




If I use the same sim for calls and internet then my internet stays On during a call.


If I use one sim for a call and then the 2nd sim for internet then internet disables during a call.


From googling I've read that some say having voLTE activated on the calls means internet remains !


Unfortunately as I'm a Payg Customer my UK Network isn't providing 4G calling aka voLTE to my account yet.


So in conclusion this looks to be a network restriction and not a restriction of the Phone itself.
