How to Change WhatsApp Phone Number on iPhone
Pretty soon, SIM cards will be extinct and swapping your current phone plan will be as easy as installing a new app. But even today, people are getting new cell contracts while swapping their cell provider, which often comes with a new number. As you may know, WhatsApp usage is tied to a phone number for several reasons. Thus it makes sense to know how to change a WhatsApp phone number to continue usage on the new phone number.
Why does WhatsApp even require my number in the first place?
WhatsApp uses your regular GSM phone number to make sure that spammers can’t abuse the platform for illicit advertising purposes. This is one of the major reasons you always have to provide a phone number when installing and activating WhatsApp. Of course the linking of a phone number is also useful for law enforcement purposes and the tracking of harassers or (potential) terrorists.
