What is email to sms?
Email to sms is a service provided by an SMS gateway software. It allows the user to send an e-mail, and the SMS gateway will convert this e-mail to a text messages and will forward it to a mobile phone.
How does email to sms work?
The most simple email to sms solution requires a techical email box (email@example.com in Figure 1). When the user (firstname.lastname@example.org) wants to send an sms, he will send an e-mail to this technical email address (email@example.com). He will put the mobile phone number (+362011111) into the subject line of the email, and the sms text into the email body.
Ozeki SMS gateway will operate this technical email box. It will download the incoming email (using IMAP), and will forward it as SMS to the mobile network through a mobile phone attached to it. The attached mobile phone in our example (Figure 2) has a phone number of +3620222222. The mobile user, whose mobile phone nubmer is +36201111111 will receive the SMS, and can reply to it. To understand how the SMS reply is sent back to firstname.lastname@example.org check out the sms to email page.
How can I use email to sms?
To setup the most simple e-mail to sms forwarding you need to:
- Connect your Ozeki SMS gateway to the mobile network.

Step 1 - Connect your email to sms gateway to the mobile network
To connect you email to sms gateway to the mobile network you have quite-a-few options. The ideal option for your environment depends on the number of sms you prefer to send. For text message volumes up to 12 000 sms per day, the best option is to use a GSM modem or an Android mobile phone as an SMS gateway. The advantage of this choice is that it often allows you to send unlimited SMS messages free of charge.
For higher SMS volumes you can switch to online SMS services. When you use on-line SMS service providers you can use a dedicated SMS protocol or an SMS API. There are various SMS protocols out there: SMPP protocol, CIMD2 protocol, UCP/EMI protocol and there are many proprietary protocols based on HTTP. Protocols based on HTTP are called HTTP SMS APIs. The best option to connect to on-line SMS services is to use an SMPP connection. The SMPP protocol is widely used in the SMS industry. It is used by mobile network operators to exchange SMS traffic between each other. SMPP was designed for SMS, and it gives you high performance, instant access to submit and delivery reports and precise time stamps related to SMS delivery. So choose SMPP if possible.

The next step is to connect your SMS gateway to your Email server. On your Email server you will have to create a technical email address (email@example.com), and you must allow Ozeki 10 SMS gateway to download emails from this email box.
