If you need to send a message to someone, or even to yourself, but don’t have your phone nearby, this is entirely possible using email or a wide variety of messaging services.
Steps
Using email

Open your email service or app.

Compose a new message.

The recipient's address should begin with their phone number (including the area code) written consecutively. For example, for the phone number (555)555-1234, it would be written as 5555551234@.

Nhập tên miền dịch vụ mà bạn đang gửi tin nhắn đến. Bạn cần biết nhà mạng của người nhận. Thêm tên miền vào cuối địa chỉ. Ví dụ: nếu số điện thoại ở bước trên là số của mạng AT&T ở Hoa Kỳ, địa chỉ email người nhận sẽ là [email protected].
