How to Email an Isatphone (Inmarsat Satellite Phone)

You can send a text message to an Inmarsat IsatPhone using Inmarsat’s Email-to-Text service, which delivers the email as an SMS message to the satellite phone.

Important:

• Messages must contain plain text only.
• Do not include images, attachments, HTML formatting, or an email signature.
• Leave the subject line blank.

Steps to Send an Email to an IsatPhone

1. Open your preferred email client (e.g., Outlook, Gmail).
2. In the To field, enter the IsatPhone number followed by @message.inmarsat.com.
   • Format: 870xxxxxxxxx@message.inmarsat.com
   • Example: 870776123456@message.inmarsat.com
3. In the body of the email, type your message.
   • Keep it under 160 characters (standard SMS length).
   • Leave the subject line blank.
4. Send the message — it will be delivered to the IsatPhone as a standard text.
