If you have an iPhone, you can download tonos para whatsapp from iTunes. However, you will need to allow the Contacts app to access your media. You can also use your iPhone's ringtones to customize your alerts. If you want to send your ringtones to someone else, you will need to visit an SMS gateway Web site. These sites require you to provide a code, which is used to send your message to the recipient's phone.
If you are looking to get ringtones for your Android, you can choose from a variety of free apps. However, you may have to pay to download ringtones from some of these apps. You may also have to pay a small fee if you want to download more than one song.
