How to enter WhatsApp for the first time
If you don't have an account yet and want to find out how to enter WhatsApp for the first time, proceed as follows.
A device was used Android, after installing and starting the official WhatsApp app (if you have a smartphone without Google services, you can download it from its official website), accept the conditions of use of the service by pressing the button Accetta and continue and give consent for access to contacts, by pressing on the voice Continue.

How to enter WhatsApp with another number
Are you already registered for WhatsApp but would like to use the app with a second number? At the time of writing, WhatsApp does not integrate a function that allows you to use multiple accounts at the same time (or the same account on multiple phones).
The only thing you can do, if you want to "bypass" this problem and enter WhatsApp with another number, is to resort to WhatsApp Business: the version for business users of the messaging platform (which can also be used without problems by private individuals) which can be installed at the same time as the standard version of the application and allows you to register with a different number than the latter.
After installing WhatsApp Business, which is available for Android (if you have a device without Play Store, you can take it from an alternative store) and iOS, all you have to do is register the second number you want to use on WhatsApp Business, following a similar procedure to the one I showed you in the previous chapter dedicated to the "classic" version of WhatsApp: apart from the presence of some specific function for the business, in fact, the applications are identical.
If you want to know in more detail how to proceed, I refer you to reading my guide on how WhatsApp Business works.
How to enter WhatsApp without SIM
Do you want enter WhatsApp without SIM? This can also be done. In fact, to use WhatsApp on a device, the SIM associated with your account does not need to be inserted in it. The thing that matters, in fact, is that when configuring the account the SIM is inserted on any device capable of receiving the SMS with which to verify the number (clearly it must not be a number already associated with another copy of WhatsApp, under penalty of immediate disconnection from the latter).
In fact, there are also some online services they provide temporary numbers can be used to register on WhatsApp but, from what I have been able to personally see, they almost never work (as the numbers are few and are almost always already used by other users for the purpose in question).
Anyway, if you want more information on how to use WhatsApp without SIM, I urge you to take a look at the tutorial I have dedicated to the topic.
