With iPhone holding a 58.65% market share in the US and 28% globally, iMessage has become deeply embedded in workplace communications, particularly within financial services.
However, this widespread adoption has exposed critical gaps in regulatory compliance frameworks that were designed for more traditional communication channels.
The consequences of improper iMessage compliance practices have become increasingly severe.
In 2024 alone, the SEC handed out over $600 million in fines for messaging compliance violations—pushing the total past $3.5 billion since 2021. It’s a clear sign that organizations need to get serious about the compliance risks tied to Apple’s messaging platform.
In this article, we’ll cover different iMessage compliance challenges, including:
- How iMessage archiving works for BYOD
- Dual SIM and personal messages archiving issue
- RCS and cross-platform security
- iMessage end-to-end encryption vs. compliance
The BYOD Archiving Dilemma: Where Privacy Meets Compliance
The rise of Bring Your Own Device (BYOD) policies has made iMessage compliance more complicated than ever.Unlike traditional communication channels that can be easily segregated between personal and business use, iMessage’s architecture makes it virtually impossible to capture only business-related communications from personal devices.
When employees use iMessage for business communications on personal devices under BYOD policies, all personal communications are also captured, creating massive privacy concerns.
This all-or-nothing approach forces organizations into difficult decisions — either accept the privacy implications of comprehensive message capture or risk non-compliance with regulatory requirements.
The technical reality is stark. iMessage does not route via mobile carriers, making it almost impossible for carriers to create an archive of messages sent and received on devices. This fundamental architectural difference compared to SMS means that traditional mobile device management (MDM) tools often cannot effectively monitor or archive iMessage communications.
Organizations have attempted various workarounds, including implementing “disable or block” policies for iMessage.
However, these approaches are still unreliable.
The case of Deloitte illustrates this perfectly. Their iMessage blocking system became ineffective after iOS updates. This resultet in 95 out of 99 firm-owned iPhones operating with the non-compliant iMessage functionality fully enabled, leading to approximately 676,000 unarchived business communications and a $200,000 FINRA fine.
To address BYOD archiving challenges effectively, organizations should establish clear policies that require employee consent for comprehensive message capture when personal devices are used for business.
It is crucial to take data privacy into account and ensure that employees are fully aware that data from their personal devices is being captured.
Dual SIM Complications: One Device, Multiple Compliance Headaches
The adoption of dual SIM technology has introduced another layer of complexity to iMessage compliance. Many professionals now use devices with separate personal and business lines, expecting to maintain clear boundaries between their professional and private communications.
However, Apple’s implementation of iMessage with dual SIM devices creates serious compliance challenges. Users typically have one Apple ID for both SIMs, and iMessage registration can be problematic when trying to use two different numbers on the same device.
This limitation means that organizations can’t easily separate business and personal iMessage communications even when employees have dedicated business phone numbers.
The technical constraints are particularly frustrating. When you register a number for iMessage, it has to be used on a device, and in Apple’s database structure, registering another number on the same device may disconnect the former one.
This database limitation prevents the seamless dual-number iMessage functionality that businesses need for compliance.
For compliance teams, this creates a blind spot where business communications that happen through iMessage on dual SIM devices may not be properly captured or attributed to the correct business context.
Organizations must address these dual SIM scenarios by potentially requiring separate business devices or specialized archiving solutions that can handle the complexity of Apple’s iMessage architecture.
The Personal Message Filter Problem: An Impossible Separation
One of the most persistent challenges in iMessage compliance is the inability to filter out personal messages when capturing business communications.
Unlike platforms such as WhatsApp Business, which offers separate applications for personal and professional use, iMessage and Signal do not enable users to switch between personal and business communications, as data can only be captured in its entirety through the phone number linked to the device.
This technical limitation forces organizations into uncomfortable positions regarding employee privacy. When an employee uses iMessage to conduct business communications with clients on a BYOD phone, all personal communications will also be captured.
The lack of granular control over message types means that compliance solutions must choose between comprehensive capture (violating privacy) or selective capture (risking regulatory violations).
The regulatory landscape hasn’t adapted to these technical realities. Financial firms, in particular, face strict requirements to capture all business communications, but regulators have not provided clear guidance on how to balance these requirements with employee privacy rights when using platforms like iMessage.
Organizations are exploring various solutions to this challenge, including requiring employees to use dedicated business messaging platforms or implementing “governed mode” solutions. However, these solutions often require significant changes to existing communication workflows and employee behavior.
RCS and the Cross-Platform Security Gap
The introduction of Rich Communication Services (RCS) support in iOS 18 has created new compliance challenges while potentially addressing some existing ones.
RCS messaging offers enhanced features such as read receipts, typing indicators, high-resolution media sharing, and stronger encryption, but these capabilities come with their own compliance implications.
The cross-platform nature of RCS messaging between iOS and Android devices introduces new security considerations. While the GSMA (The Groupe Speciale Mobile Association) has formally announced support for end-to-end encryption for RCS using the Messaging Layer Security (MLS) protocol, the implementation across different platforms and carriers remains inconsistent.
For compliance purposes, this inconsistency makes staying compliant a real challenge.
When a recipient’s device or carrier does not support RCS, communication may fall back to SMS or MMS, which lack advanced encryption to protect messages. This fallback behavior means that organizations can’t rely on consistent security and archiving capabilities across all communications.
The regulatory implications are still evolving. Cross-border transmissions may trigger different jurisdictional requirements, and secure storage, encryption, and strict access controls are necessary to protect RCS message archives.
Organizations must now consider not only traditional SMS and iMessage compliance but also the hybrid world of RCS communications that may behave differently depending on the recipient’s device and carrier capabilities.
Moreover, organizations that can’t properly capture and archive RCS communications risk regulatory penalties, litigation challenges, and reputational damage. The stakes are particularly high in financial services, where the SEC has shown increased scrutiny of digital communications.
Encryption vs. Compliance: The Fundamental Tension
At the heart of many iMessage compliance challenges lies the fundamental tension between Apple’s commitment to user privacy through end-to-end encryption and regulatory requirements for message retention and monitoring.
iMessage is end-to-end encrypted, and unlike email servers that store messages in accessible formats, iMessage data requires specialized tools to extract and archive messages without violating encryption protocols.
This encryption creates a technological barrier that traditional compliance infrastructure was not designed to handle.
Most legacy compliance infrastructure was designed for email and phone records, but not encrypted instant messaging apps, creating a tech gap that leads to inefficient integration.
The challenge is made worse by Apple’s philosophy regarding message storage. Contrary to email platforms that offer built-in compliance features, Apple doesn’t provide native tools to archive iMessage conversations. This forces organizations to rely on third-party solutions that must work around Apple’s security measures while maintaining compliance integrity.
Some attempt to address this by requiring employees to disable iMessage entirely, but this approach has proven problematic. As shown in the Deloitte case, technical controls like “Disable or Block” policies require ongoing verification, especially after system updates, and failures in these controls can lead to major compliance gaps.

Summary of the Main Points
- iMessage is widely used in business, especially in finance, but its encryption and architecture make compliance extremely difficult. Traditional archiving tools are not equipped to capture iMessages effectively.
- BYOD policies create privacy and compliance conflicts. Capturing business iMessages from personal devices often leads to the unintentional collection of private messages.
- Dual SIM devices complicate message attribution. Apple’s system ties iMessage use to a single Apple ID, making it hard to separate business and personal communication.
- There’s no way to filter personal from business iMessages without workarounds. Unlike apps like WhatsApp Business, iMessage doesn’t support separation or message labeling.
- RCS adds another compliance layer. While offering cross-platform support and encryption, inconsistent implementation across carriers creates archiving and security risks.
- Encryption clashes with compliance mandates. iMessage’s end-to-end encryption blocks traditional archiving methods, forcing companies to rely on third-party solutions.
- Regulators are not making exceptions. Firms that fail to capture and retain iMessage communications are facing heavy fines and increased scrutiny.
- Workarounds like disabling iMessage are unreliable. iOS updates can break enforcement tools, as seen in high-profile compliance failures.
- Effective compliance requires a combined effort. Organizations need the right technology, clear policies, and employee participation to meet regulatory expectations.
- To overcome the issue of archiving personal communications organizations can blacklist personal contacts or Apple IDs to prevent private messages from being captured, while requiring clear employee consent for any data collection from personal devices.
