Apple says its iPhone messaging is still the 'best' despite a new RCS upgrade that promises end-to-end encryption. The RCS upgrade, which has come to both iPhone and Android, will 'improve privacy and security,' according to the GSMA.

So, what's the catch? The GSMA acknowledges that the new encryption only works once it's enabled by supporting mobile network operators. This means the rollout will be patchy. It won't happen quickly.

The GSMA is now encouraging its members to leverage these new capabilities and enable more secure RCS messaging for personal and business users worldwide. However, this won't be easy, given the complex global cellular ecosystem that must upgrade for this to really be 'end-to-end.'

Until then, Apple is clearly right. The 'blue bubbles' that indicate iMessage conversations are the only certainty in its walled garden. Apple says that iMessage was built with privacy in mind and has always been end-to-end encrypted. Every message flagged by those blue bubbles is secure.

'It remains the best way to communicate between Apple devices,' Apple says. 'All RCS and MMS/SMS messages, regardless of encryption, appear in green text bubbles on your device,' Apple adds. 'Learn how to have blue bubbles instead.'

The GSMA describes the RCS encryption upgrade as a collaborative industry effort involving Apple, Google, and the GSMA to strengthen modern mobile messaging standards. However, Apple never seemed that keen on this effort.

This is much more critical to Google, which came late to the end-to-end encryption party with Google Messages. Google used this platform to drive the adoption of RCS across Android, having grown frustrated with a slow carrier rollout.

The GSMA says that for smartphone users, the RCS upgrade benefits are simple. E2EE RCS messages can't be read by anyone but the sender and receiver when they're being sent between Apple and Android devices, even by Apple or Google.

This should provide users with the highest level of privacy and security while messaging. But until the upgrade is fully rolled out, Apple's iMessage remains the best option for secure messaging.

We don't yet know how fast this will actually happen. There's a very complex global cellular ecosystem that must upgrade for this to really be 'end-to-end.'

  • The RCS upgrade promises end-to-end encryption for messaging between Apple and Android devices.
  • The GSMA is encouraging mobile network operators to enable the new encryption.
  • Apple says iMessage is still the best way to communicate between Apple devices.
  • The rollout of the RCS upgrade will be patchy and won't happen quickly.
  • Google is more invested in the RCS upgrade, having come late to end-to-end encryption.

The implications of this upgrade are significant. If successful, it could mean that messaging between different devices becomes more secure. However, until then, Apple's iMessage remains the best option.

In the US, where Apple and Google dominate the smartphone market, this upgrade could have significant implications. It could change the way people communicate, making it more secure and private.

As the world becomes increasingly digital, the need for secure messaging is becoming more pressing. This upgrade is a step in the right direction, but it's not a solution yet.

For now, Apple's iMessage remains the best option for secure messaging. But as the RCS upgrade rolls out, we may see a shift towards more secure messaging across different devices.

It's a development that's worth watching. Will it be successful? The outcome is uncertain, and it's likely to take time to determine the impact. The success of this upgrade will depend on various factors, including the speed of rollout and user adoption.
