Hello. I hope it is OK for me to write in English.
I received today a SIM card for NOS prepaid to test at home if I can do wifi calling with NOS.
I cannot find the definitions to choose wifi calling in my phone, so I am afraid that my J5 2016 is not suitable for this service.
Can you confirm that?
My problem is that I have no signal in my house and was hoping to be able to use wifi calling at home.
Thank you for your attention.
