Your comment is disingenuous.

Adding the 2018 YouTube Chat isn't fair. Google has products that allow communicating between users. It was never meant to be any replacement for SMS, it was simply a chat system within YouTube. You know, the same YouTube that has had DM's since day 1?

You also said in 2016 Google encourages people to use the Google Messages app. The same app being used today.

Google also launched other apps around the same time. Apps that were in development for a while. Then they shut them down, to focus all of the features/time into Google Messages.

You're also adding very specific apps that Google never intended to make into an SMS app. Like Google Chat or Hangouts Rebrand.

Your timeline is disingenuous. Essentially from 2016 - NOW Google has been working on making Google Messages the one stop shop. Only 5 years less than Apple has been making iMessage.

Samsung supported RCS natively in their messaging apps since about 2013, and my carrier released their own RCS+SMS messaging app around that time to bridge the gap for non-samsung android users

Google was pretty late to the RCS boat lol

I would like to use it but no one else does

Signal removed SMS integration, making adoption less likely.

When I could install Signal on my parents phones, and they could SMS and Signal message in the same app, it was great. Especially since any contacts that happened to have Signal, it just worked. My parents didn't have to do anything.

After Signal removed SMS, my parents just open up Google Messages and message everyone from there. They don't want to juggle two apps. They also don't really understand it. They just go back to the "main menu", select their friends name, and type. Signal shot themselves in the foot.

It is less that people use SMS and more that people just don't use WhatsApp. I have a mix of group chats, including some with SMS and Facebook Chat. However, no one uses Whatsapp.

they're free

They were not always free, and when they were, they were up to a limit. Yes the limit was something absurd, but surprisingly, some people did hit them.

That's why as soon as phones had easy access to the web and enough bandwidth to last a month, people started treating SMS like a last resort, and I have not met a single culture on Earth that didn't think this way in the transition period up to when what you said became universally true.

Plus... People don't want to message only their "contacts", nor want their phone address book filled with trash. Mindblowing, know, who would have thought (other than US apple users????). Facebook's Messenger was one of the earliest to give that to the wide public and it got heavily adopted. But people moved on from even that.

They're not "free", many places still charge per SMS. Even if your country doesn't, you NEED an SMS plan, which costs more than a basic data-only plan. SMS is extremely unsecure. They don't work "everywhere", especially if you're travelling, and your country charges extreme fees to receive SMS out of country (for reference, Canadian carriers charge $15/day to use your phone outside Canada. That's one expensive ass text..).

That being said, I think it's crazy that a large portion of Europe has adopted WhatsApp. I wouldn't touch that Meta garbage with a 100 kilometre pole.

They are not free here but since like no one other than my grandma uses them it's not really important.

They're limited as hell and buggy. The thing that most bothers me is the character limit and then your device sends out multiple SMSs, other devices may not understand that and instead of receiving one message you receive multiple broken ones.

Accents, anything not in the English alphabet: á ä ā ą é ê and so on, good luck with those.

Attaching media is a nightmare, basically the entire MMS protocol is broken.

You're relying on your carrier and your recipients carriers.

International messaging is also completely broken for the reason above. You can forget any media in that case too.

Geez I don't know if I should continue. Did you know SMS was not a feature planned in phones originally but rather it takes advantage of a bug that was never fixed?

In Brazil where I'm originally from people stopped using SMS altogether as soon as the first iPhone got in the market. Android followed shortly after. Viber was the popular choice back then, now WhatsApp is the standard.
