The user has moved to Europe.  They had a working WhatsApp account in the US before they left. They cancelled their AT&T wireless account before they went to Europe.
Will WhatsApp still allow them to receive and make WhatsApp calls while they are in Europe using the same iPhone, which now has a European SIM?
Is the phone number used only as an identifier?
Thanks.

If cell phone is cancelled, will WhatsApp keep working?

iOS is a mobile operating system developed by Apple; it is a derivative of the Mac OS X desktop operating system, with which it shares many (but not all) common frameworks and other components. These include Cocoa Touch, the Mach/Darwin/XNU kernel and code from the Berkeley Software Distribution (BSD). Each iOS application runs in its own secure sandbox to prevent altering other applications, the operating system, or any other data.

The iPhone is a smartphone made by Apple Inc. It and the iPad, along with several other mobile devices from Apple, run on the iOS operating system, which has its own topic, as does the iPad for device-specific questions. Native iOS applications are written in Objective-C or in Swift using the Cocoa Touch frameworks or HTML5 compiled with the help of a package manager such as Adobe PhoneGap; a common IDE is Xcode.

A cellular phone (also known as a mobile phone, cell phone, hand phone, or simply a phone) is a telephone that can make and receive telephone calls over a radio link while moving around a wide geographic area by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. Mobile phones that offer services such as text messaging, email, Internet access, business applications, gaming, photography and more general computing capabilities are referred to as smartphones.

Cell Phones

A smartphone or smart phone is a mobile phone with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use. They typically combine the features of a cell phone with those of other popular mobile devices, such as personal digital assistant (PDA), media player and GPS navigation unit. Most smartphones can access the Internet, have a touchscreen user interface, can run third-party apps, music players and are camera phones. Most Smartphones produced from 2012 onwards also have high-speed mobile broadband 4G LTE internet, motion sensors, and mobile payment mechanisms.

Instant messaging (IM) is a type of online chat that offers real-time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non-IM types of chat include multicast transmission, usually referred to as "chat rooms". Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (a central server retransmits messages from the sender to the communication device).
