Unlocked Phone not receiving calls

[2860]

Hi @ links to members

My iphone stopped charging so removed my SIM to my old Samsung Galaxy 6 which has been unlocked. I am receiving text messages but not phone calls. Unsure why.

I am currently in the USA and have a new US phone so to set up some of my apps (especially banking Apps) I need to receive a call on my old number for verification but for some strange reason nothing is coming through on my Galaxy 6.

Any advice?

@2860  Try a manual network search and connect to a different network.

is you sim on contact or PAYG ?  
Are these messages text messages or RCS messages?  
is the Samsung device connected to WiFi ?
