Google’s “unofficial lyric explainer” video explains that “Texts Go Green” refers to the phenomenon when an iPhone user gets blocked, or tries to text an Android user. A sarcastic message at the end of the video says that it is a problem Apple can fix by adopting Rich Communication Services) RCS.
Green bubbles have long been part of the Apple community. Inside the default Messages app, blue chat bubbles mean an iPhone-to-iPhone conversation. When an iPhone user texts an Android user the chat bubbles are green.
Those green chats are SMS messages and there is a real social effect since SMS doesn’t support rich iMessage’s features. Some, like message reactions, get broken if an Android user is in a group chat with an iPhone user.
An iPhone user can long-press a chat to give it a heart, thumbs up, or a different reaction. The Android user sees a text version of the emoji instead of a graphical representation: “[User] loved [text message].”
Rich Communication Services
RCS is a messaging protocol designed as the successor to the older SMS and MMS protocols. It supports iMessage-like features in all texting.
Formed in 2007 it was brought into the GSM Association where it was slowly refined. Features were added over the years, such as group chat, file transfer, visual voice mail, and even chatbots in 2017.
But the rollout of RCS has been messy. Not all carriers and devices support the protocol and it can be implemented in different ways, such as encryption.
Unlike iMessage, end-to-end encryption is not built-in to RCS. Carriers and companies can add such encryption if they choose. Google added support for this encryption in 2020 but only for one-on-one conversations.
Like SMS, RCS relies on an active phone number. Texting gets tied to a cellular bill and can vanish if a payment is missed or because of other cellular network chicanery.
Google offers RCS communication in its Android Messages app as the default. No matter how many messaging apps Google goes through, Android users can have those rich features as long as Google supports RCS.
Apple doesn’t need RCS
People with iPhones aren’t going to stop texting their Android friends just because a green bubble appears. And, the iMessage stigma is only in the United States. Internationally, alternatives have a much higher adoption rate.
These apps support rich features that both ecosystems can enjoy because they’re using the same app. These apps use neither iMessage nor SMS, making them universal. Only an internet connection is required.
Apple probably didn’t create iMessage as a way to lock people into iOS at the start, but the platform has certainly grown that way. It’s effectively a social network, one that Apple can upgrade without waiting on industry associations and carriers.
Apple has shown no interest in releasing an iMessage app for Android either. In the past it was revealed that Apple executives said that an Android version is possible, but would “hurt us more than help us.”
Encryption and other enhanced features are advantages that RCS has over SMS, but for now, it seems the only way Apple is going to support it is if SMS went away entirely.
For now, RCS is merely an alternative and not yet a standard. Despite adoption by some carriers and some companies, it is too little, too late unless Google makes significant changes and improvements.
