IMessage costs

iMessage is a service that allows you to send text messages, voice messages, photos and videos to Apple devices such as iPhone, Mac and iPad using the Internet connection.

The only expense to have to have iMessage on your device is the activation cost, equal to 0,30 € (or the cost of an international SMS according to the tariff of your operator). Subsequently, the service has no recurring cost and allows you to send messages for free, provided you have an active Internet connection (Wi-Fi or 3G / 4G) and communicate with another person in possession of an iMessage account (otherwise a classic SMS is sent at the cost foreseen by your tariff plan).



Any reactivation of the service after a deactivation entails an additional charge of 0,30 euros. The charge, therefore, occurs for each activation and not for the activation of the single account.
