Upco Mobile Messenger 1.0.9

Upco Mobile Messenger offers a promising solution for secure and efficient communication, utilizing multi-level encryption to ensure user privacy. It allows users to connect with others on the platform for free, using simply their phone number as an identifier. Notably, the service prioritizes user privacy by not storing any communication or usage history on its servers.

This application demonstrates robust performance across various network conditions, including those with limited bandwidth such as 2G or EDGE. Despite these constraints, Upco maintains a commendable quality in audio and video calls, delivering HD resolution at 720p while consuming less data compared to many other messaging platforms.

Additionally, Upco extends its functionality beyond its user base through Upco-Out, enabling users to make calls to landline or mobile numbers with the purchase of flexible calling plans or through international airtime top-ups.

Main features include:

• Fast and secure communication backed by multi-level encryption, with no retention of communication history on servers.
• Seamless operation even in slow or crowded network environments, utilizing less data than competing messaging services.
• Free high-definition audio and video calls to other Upco users, with automatic detection of contacts using the app.
• Free instant messaging and private group chats, enhanced with a variety of stickers and personalization options for chat backgrounds and images.
• Capability to send any type of file, contacts, or locations within chats without restrictions.
• Flexible calling plans available for local and international calls to non-Upco users through Upco-Out and Callback services.
• PUSH notifications to ensure that users do not miss messages and calls even when the application is not active.
• Control over data retention after logging out; users can choose to keep or delete their communication history on their individual devices.

*It is important to note that Upco utilizes your internet connection, with recommendations for Wi-Fi use as network data charges may apply based on your personal data plan settings.
