What's new?

1. T-Satellite Network support

• The MultiLine mobile app now supports T-Satellite Phone Service from T-Mobile on devices with this capability, allowing for seamless connectivity in open areas where traditional cellular or Wi-Fi coverage is not available.
• When connected via satellite, users can send and receive messages via SMS, MMS, WhatsApp, WeChat, and LINE, as well as access voicemail.
• Initially, while on the satellite network, specific functions such as voice calls, Exchange contact sync, and onboarding will be disabled due to satellite bandwidth restrictions.
• The app will provide feedback when these features are unavailable.

See Using MultiLine on Satellite Network for more information.

2. Updated Microsoft Intune SDK

• We’ve upgraded the Intune SDK to version 21.0.0.
