Remember when the popular messaging app Signal announced it would no longer support regular text messages (SMS and MMS)? A lot of people were confused, even upset. For years, many of us used Signal as our main app for all messages, both secure ones and standard texts.
It felt like a sudden change, leaving many wondering why a useful feature was being taken away. But the reasons behind this decision are more complex than you might think, touching on big problems in how our phones send messages today.
The Big Change No One Saw Coming
For a long time, Signal offered a simple way to manage all your messages in one place. You could send encrypted messages to other Signal users and regular SMS texts to everyone else. This made it a convenient choice for many, bringing a sense of security to their daily communications.
Then came the announcement: Signal would remove SMS and MMS support. Users would need a separate app for their standard text messages. This news sparked a lot of discussion and left many users looking for answers about this significant shift.
Why Signal Dropped SMS: The Real Story
Signal isn't just trying to make things harder for users. Their decision came from deep technical problems and a desire to stay true to their mission of secure, private communication. The company shared some key insights into why this change was necessary.
They explained that supporting insecure protocols like SMS was actually causing more harm than good. It created confusion, technical headaches, and even made Signal look bad for issues it didn't cause. It was a choice made to protect Signal's core purpose.
The
Rise of RCS and Its Problematic Nature
One major reason for dropping SMS is the upcoming technology called RCS (Rich Communications Services). Think of RCS as the next generation of SMS, offering features like typing indicators, read receipts, and better media sharing, similar to modern chat apps.
The problem is, *RCS doesn't play well with third-party apps
- like Signal. Imagine trying to send a text to a friend through Signal, but their phone automatically replies using RCS, and you never see their message. This kind of communication breakdown is only going to get worse as RCS becomes more common.
Signal cannot add RCS support because Android phones don't offer an easy way for third-party apps to connect to it. This means that, eventually, any app trying to handle SMS on Android will run into big problems with RCS. The days of using an app like Signal for all your texts are truly numbered.
The Hidden
Difficulties of SMS Support
Supporting standard SMS and MMS is surprisingly difficult, even for a well-made app. Signal has to make its app work perfectly across thousands of different Android devices, running many different versions of the operating system. Add in hundreds of cell phone carriers, and you have a recipe for constant bugs.
The SMS protocol itself is old and full of quirks. Signal spent valuable time trying to fix these issues, time that could have been used to improve its secure, encrypted messaging features. It was an investment in an insecure system, pulling resources away from their main goal.
When SMS Goes Wrong:
Bugs and Blame
Many common problems with text messages are actually flaws in the SMS protocol itself, not the app sending them. For example, a few years ago, old Valentine's Day messages were delivered nine months late to many people. This was an SMS bug, but some users blamed Signal for it.
