You can choose to use your Facebook account with the Log In with Facebook button. If you do not have a Facebook account or do not wish to link both profiles, tap on Sign Up with Email Address or Phone Number. The process shown below corresponds to the latter option.

Enter your phone number or email to continue.

Instagram will send you a verification code. Type it in the following text field and tap Next.

Then, you will have to provide some personal information. First, your name and password. Then, your age. After specifying your date of birth, tap Next.

Instagram will have generated a username for your profile. You can change it by tapping on Change username or proceed with the registration with Sign Up.

Instagram will insist on asking you to connect your Facebook account. You can skip this step with the Skip button.

On the next screen, you will be able to upload a profile picture. It is also possible to skip this task and perform it later.

Before we finish, you will see some suggestions of accounts that you may be interested in following. It is the ideal way to fill your news page with content.
