Do you filter text messages?

Yes. In order to provide a comfortable experience for many users, we filter content that violates the law, is dangerous, involves pranks, is violent, promotes discrimination, or has a high likelihood of spam during the message processing. Additionally, to prevent privacy exposure, we filter messages from unauthenticated phone numbers. Displaying all messages received by SMSOnline could potentially be misused by malicious individuals to reveal third-party privacy on the site or attempt to lure users into phishing or scams.

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.

Is registration required for using SMSOnline? Additionally, is there a risk of virus infection?

No registration is necessary to use SMSOnline. We value privacy more than anyone else in the world.
However, SMSOnline operates under the laws of Hong Kong, where it is based. Please refrain from using our services maliciously, such as by exposing third party privacy.

Our site is supported by advertising revenue. Internet advertising is often pointed out to be at risk of malvertising, but you can use our services with peace of mind as we entrust the management of our advertising space to reliable partners.

Are there any prohibited actions?

These ASNs and IP addresses are accesses from VPS or SaaS like Amazon AWS, and are clearly distinguished from general access, so we will never mistake them for general users. We continue to fully respect the privacy of bona fide users of us.
Malicious accesses are automatically detected by Cloudflare WAF and this list is to be updated from time to time after human inspections.

And we want to ask all users; Please do not use any websites that steal our phone number.
These sites regularly visit our site and copy messages, but the frequency is only about once every 30 minutes, meaning your message will not be posted on the website while it is valid.

Our website only lists phone numbers that we and our volunteers have helped us obtain, and we shall never allow other websites to steal them.

These accesses are totally illegal since are attempted by our competitor websites to interfere with our normal operation. If investigators require further information, please contact [email protected] and we will share all information we hold.
