Frequently Received Inquiries

Before explaining how to use, we will address three frequently asked questions to alleviate your concerns.

All frequently asked questions can be found on the "FAQ" page.

How does the SMSOnline system work?

SMSOnline automatically posts text messages received by phone numbers managed by the SMSOnline Operating Team and phone numbers provided by paid volunteers on the website.
We use our independently developed Android app to monitor text messages arriving at your phone number and send them to a server we manage. On our servers, we filter harmful messages based on the text of the email and the sender's phone number.
Finally, we serialize the sender against our SMS database and store the message in an SQL database for use on our website. At this time, the sender's phone number is discarded and not stored in the database for privacy reasons.
This series of tasks uses open source APIs such as android.provider.Telephony API. We are also developing natural language processing models to identify and eliminate harmful messages using datasets with anonymized senders.
