SMS texts (e.g., the green messages on iPhones, and most messages sent from the stock Chat app on Android devices) are not encrypted, which sets them apart from most internet-based messaging services like iMessage or WhatsApp. Accordingly, it’s best not to include sensitive data like a bank account number within them.

Apps like Slack and HipChat are enormously popular in today’s workplaces. However, they log your conversations and may allow supervisors to view information without your knowledge. Use discretion or resort to other communications channels for private matters.
