**Important:**

* As an sender's adress the email must include an adress that you have registered in the list of allowed sender adresses in the personal settings.
* In the menu option 'Settings: Access via e-mail' the check box 'I allow messages to be sent via my eCall account by email' must be activated.
* You have to write the telephone number in the international format. Example for Switzerland: 0041 or +41

**Note**
* The capitalization of the recipient's identification doesn't matter.
* Write down the recipient's identification in this format <recipients-identification>@sms.eCall.ch in the To:-box and/or in the Cc:-box of the email as you usually do it with ordinary e-mail adresses.
* If there are more recipients: <recipients-identification 1>@sms.eCall.ch; <recipients-identification 2>@sms.eCall.ch; ...)
* The message being sent to the pager/the mobile phone is composed of the e-mail's subject box and the text box.
* The adress @msg.ecall.ch that has been valid so far keeps valid.
