This article describes how Chat functionality works on mobile devices. It covers Android and iOS platforms.


Chat List screen

The Chat list screen is the best place to check active chats and initiate new chats (both one-on-one and group ones).

The conversations listed here display the last message posted. 

Android iOS
LastPostedMessage LastPostedMessageiOS

They also display the chat name (for group chats) or contact name (for one-on-one chats), and the number of unread messages.

Note: The chat sorting will constantly change. The system is designed to display the chats containing the most recent messages on top. Only pinned chats are not affected by this rotation and are displayed on top even if they don't contain any recent messages.

Chat screen

Note: if someone is composing a new message, you will be able to see the *username* is typing message on the chat's screen (works for both group and one-on-one chats).

           Note: currently system won't allow sending multimedia messages (pictures/voice messages/etc)

Initiating a new chat

Chat can only be started with a person who has Intermedia Unite services enabled. It is not possible to chat with external users.

Initiating a one-on-one chat

There are two ways to initiate a new one-on-one chat.

To start a new chat, you may tap the Chat button on the Contacts screen.

Note: if you are unable to see the Chat button nearby the contact, this indicates that the user doesn't have the Intermedia Unite services enabled or is an external contact.

Initiating a group chat

Important: once you invite the person to a group chat, they will be able to see the whole group chat message history. If the participant is removed, the chat history will be wiped from all of the user's devices. Every User can rename and add/remove members – all chat members have equal (owner) permissions.

There are two options to start a new group chat.

Note: Participants will be able to see a new chat only after the first message is posted. Also, if the chat name hasn't been specified during the creation, the system will automatically assign a generic one. However, the name can be changed to a manually defined name later on.

Creating a new chat from the Chats screen

To start a new group chat, you may tap the Add Chat button on the Chats screen. Then, the application will ask you to select multiple contacts who should participate in the group chat. After the participants are selected, tap Done, enter the chat name and confirm the creation.

Pin to top

Chats can be pinned; they will be displayed on the top of the chat list. 

Note: Pin preferences are not synchronized between user's devices and are unique for each device. Also, unlike the desktop application, the mobile application won't display the chats you have with the contacts from the favorites list at the top of your screen.

The chat can be pinned:

Chat history

  • Full chat history is retained indefinitely allowing users to access past conversations. All chat members have access to full chat history;
  • Chat history is synced across all devices;
  • The messages are encrypted when transferred and at rest;
  • At this point, the chat history can't be cleared to prevent losing critical information.


Delivery status indication

Delivery status indication notifies when a message is delivered to a collaborator.

Note: Single check mark indicates that a message has been delivered to a server. The double check mark indicates that a user has read a message (for the group chat, it indicates that at least one member of the chat has read the message).

Important: a user will receive an email with the missed messages (while offline) if they are not online for 5 minutes after the message has been sent.

Android iOS
DeliveryStatus DeliveryStatusiOS

Push notifications

Once a message is received by a user, a push notification appears. The push notification will be followed by vibration and sound.

The application behavior on Android can be adjusted in the app settings. 

My Account > Settings > General - enabling/disabling push notifications for incoming calls.

My Account > Chat - enabling/disabling push notifications for chats.

Important: iOS application only allows to use the system settings.


The counters are designed to:

  • count non-read messages in each chat on the Chat List screen;
  • count how many chats have non-read messages on the Chats icon in the main menu;

Note: if a user with several mobile devices reads a chat on one of them, this chat will be considered read on all the devices.
