Does RCS work on iPhone in India?

The position today, network by network

The iPhone column follows what Apple enables for India, which today is Reliance Jio. On Android, RCS works across Jio, Vi and Airtel wherever the handset has it switched on. The iPhone 13 floor on Jio is from our own field observation, not from a published Apple or Jio document, and you will not find it in most write-ups on this topic.

What Apple actually requires

Apple added RCS in iOS 18, released in September 2024. But the operating system is only half of it. Apple's own wording is that to use RCS you need iOS 18 and a cellular plan from a carrier that supports RCS messaging on iPhone. Support is switched on per carrier, in the carrier settings Apple ships, which is why an iPhone and an Android handset on the same network can behave differently.

Take Airtel. On Android, RCS is delivered through Google Messages, and Airtel numbers with RCS switched on receive it today. On iPhone, RCS is delivered through Apple's Messages app, and Apple has not enabled Airtel there yet. Same network, two unrelated switches, and only the Android one is on. That is why an Airtel customer on Android gets the rich message while the same person on an iPhone gets SMS.

The part that is not in the documentation: iPhone 13 and above

Here is a detail you will not find in most write-ups on this subject, and it changes your reachable numbers. On Jio, RCS works from iPhone 13 upward. It is not simply a question of the iOS version, because iOS 18 itself installs on much older hardware, back to the iPhone XS and XR. So reading Apple's "you need iOS 18" line on its own will lead you to overestimate how many iPhones you can actually reach.

The likeliest explanation is that carrier enablement reaches the handset through Apple's carrier settings bundles, which are issued per carrier and do not have to behave identically on every device. We are describing what we observe on the network rather than a rule Apple or Jio has published, so treat it as a practical floor rather than a specification.

The planning consequence is straightforward. An older iPhone on Jio, even one running current iOS, should be counted as an SMS recipient. It still gets your message, just in plain text.

The detail most pages miss: iPhone users can turn brand RCS off

iOS carries RCS business messaging, not just person-to-person chat, and Apple gives the customer a separate switch for it. Under Settings, Apps, Messages, RCS Messaging, there is an RCS Business Messages toggle. Someone can keep RCS on for messaging their friends and turn brand messages off entirely.

This is worth planning for rather than being surprised by. Even on Jio, where iPhone RCS works, a share of your iPhone audience will have opted out of business RCS specifically. They are not lost: they receive the SMS version. But it does mean iPhone reach on RCS should always be treated as a subset of the addressable base, never the whole of it.

What your iPhone customers receive right now

The practical answer is simple, and it is the same answer for every handset that cannot show a rich message. Capability is checked at send time. An iPhone 13 or newer, on Jio, running iOS 18 or later, with business RCS left on, receives the full version: your verified brand name and logo, images, cards and tappable buttons. Every other iPhone receives a clean SMS version of the same message.

So no customer is skipped because of their phone or their network. What varies is how rich the message is when it lands. That is the core reason RCS is safe to adopt as an upgrade to your existing SMS rather than as a replacement for it, and it is covered in more detail in RCS vs SMS.

One honest caveat

The two platforms do not describe iPhone business messaging the same way. Apple documents RCS business messages on iPhone, down to the setting that turns them off, and lists RCS for Jio in India. Google's documentation for RCS Business Messaging, meanwhile, notes that Apple has built its own implementation and makes its own choice of carriers, and directs iPhone questions back to Apple.

What that means in practice is that iPhone delivery depends on Apple having enabled the carrier, and no provider can promise it on Apple's behalf. So we plan iPhone reach conservatively: assume the SMS version for iPhone customers, and treat a rich delivery as upside. That way your campaign numbers hold up whichever way the platforms move.

What to expect next

Airtel and Vi iPhone support depends on Apple and the operators agreeing carrier activation, and none of them has announced a date. RCS is already live across all three networks on Android, so the direction of travel is clear even though the iPhone timing is not.

Because this is exactly the kind of status that changes without notice, we recheck this page against Apple's carrier list and operator announcements rather than restating what was true last year. The date above is when it was last verified.

How to check your own phone

On an iPhone, open Settings, then Apps, then Messages, and look for an RCS Messaging section. If the section is absent, your carrier is not enabled for RCS on iPhone. If it is present, you will also find the separate RCS Business Messages switch there. On Android, open Google Messages, then the settings menu, and look for RCS chats to see the status of your number.
