Signal has never supported SMS messages on iOS, as Apple does not allow changing the default messaging app. Those messages are stored on your cellular provider’s systemsso, instead of a tech company like Facebook seeing your messages, your cellular provider can see your messages. Your cellular provider can see the contents of messages you send and receive. Signal has been supporting SMS messaging since the time it was known as TextSecure. With SMS, messages you send are not end-to-end encrypted. SMS messages received in the app are not the same as Signal messages and do not come with similar security features. The company also shared that including SMS in the Signal app was leading to confusion for some users. Android users will therefore have to pick a new default app if they are plan to text a non-Signal user.Ĭalling plaintext SMS messages “inherently insecure”, the company said that with the rising cost of sending SMS, they have received complaints from users who have been hit with high-messaging fees as they assumed SMS messages were part of Signal messages. The platform shared that the change will only affect people who use Signal as the default SMS app on Android devices.

Signal plans to stop supporting SMS and MMS on its Android app in the coming months, according to a company blog post. The messaging platform cited security and privacy of users, and people confusing SMS with Signal text as reasons behind the decisions to stop support.
