If you're connected to 2G or a slow or unstable network, you can probably still make the calls you need. One of the strengths of Imo Lite, besides its small size, is that it performs well even with poor connections. You can create groups for your family, colleagues, friends, and more.
You can also make video calls using WiFi or your smartphone's data, talking with one person or creating groups with as many people as you want. This app lets you send text, photos, and videos. With Imo Lite, you can communicate with users who have the same version as you as well as users with Imo or Imo beta.
Imo Lite is an instant messaging app with practically all the same features as the standard version of Imo, except it takes up half the space on your smartphone's memory and consumes fewer resources, too.
