Video calls are widely used across India and Bangladesh to stay in touch with family, friends, classmates, and colleagues in other cities or countries. Call quality, however, can change with mobile data speed, device performance, and local network coverage.
Think about how you plan to use the app, including long calls, group chats, international calling, privacy, and performance on slower connections.
1. Free Video Calls Without Time Limits
People who regularly have long family conversations, study sessions, or calls with relatives abroad may find a fixed time limit inconvenient. Free calling should include both voice and video calls with no time limits or need to reconnect.
Calls made through these apps use Wi-Fi or mobile data rather than traditional call minutes, so standard data charges may still apply.
2. Group Video Calls for Family and Friends
Group video calls help families in different cities or countries join the same conversation during festivals, birthdays, and other family occasions. Relatives can exchange greetings, show decorations, or speak with family members who cannot travel.
They are also convenient for study groups and friends who want to talk together instead of making several separate calls. Participant limits, simple invitations, and clear audio when several cameras are active all affect the group call experience.
3. Check App Availability in the Countries You Call
Many families in India and Bangladesh have relatives living or working abroad, particularly in the Gulf, Europe, and North America. When both sides use the same app, video calls over Wi-Fi or mobile data can avoid traditional international calling charges.
Check whether the app is available in the countries you call most often and whether the audio stays clear during international calls. Frequent delays, frozen video, or dropped calls can make regular conversations difficult, even when the app itself is free.
4. Private and Secure Video Calls
Video calls can reveal faces, voices, homes, family members, and private chats. End-to-end encryption helps keep calls private between participants. Two-step verification, logged-in device management, and the option to sign out of old or unfamiliar devices can reduce the risk of unauthorised account access. These controls are especially useful after using the account on a shared computer, an old phone, or a borrowed device.
You should also be able to restrict incoming calls, block unwanted accounts, and control who can view your profile information. App Lock can protect your chats on a shared or unattended phone, while screenshot blocking can prevent screenshots from being taken directly during a video call. It cannot stop someone from recording or photographing your screen with another device.

5. Clear Video Calls on Slow Networks
Video call quality can vary across especially when users rely on mobile data or live outside major cities. Prioritize services built to adapt smoothly to low bandwidth without dropping calls. The app should be able to lower video resolution or frame rate automatically while keeping the audio clear. It should also allow users to switch from video to voice without ending the call when the connection becomes too weak.
imo adjusts video quality according to the available connection and prioritises audio on slower or unstable networks, helping conversations continue when the signal weakens.
6. Works Well on Android Phones
In India and Bangladesh, a video call app may need to run on anything from an entry-level Android phone to a newer premium device. An app might run fine on a brand-new phone, but if you’re using a budget Android device, heavy apps will slow your system down or hog your storage.
Check the app’s minimum Android version, download size, RAM requirements, and storage use before installing it. For example, imo Lite has a smaller app size and is designed to run on phones with limited RAM and slower networks, making it an alternative when the standard app is too demanding for the device.
7. Video Calls on Phones and Desktop
A video call app should not limit users to a phone. Mobile access is convenient while travelling or away from home, while a desktop provides a larger screen for long family calls, online classes, and work discussions.
Check whether the same account can be used on both devices and whether contacts and conversations remain available after switching. Moving to a desktop should not require creating a separate account or sending a new invitation from another service. This gives users the flexibility to answer a quick call on their phone and use a computer when they need a larger display, a fixed camera position, or easier hands-free calling.
Why imo Is a Good Choice for Video Calls in India
imo is available in 162 countries and supports free voice and video calls without a fixed time limit, including group calls. It can be used for conversations within India and Bangladesh as well as regular calls to relatives and friends abroad.
When the connection becomes unstable, imo adjusts video resolution and frame rate while prioritising audio. Android users can choose between the standard imo app and imo Lite, while desktop access provides a larger screen for longer calls.
Call privacy settings, two-step verification, device management, App Lock, and Screenshot Blocking give users more control over their accounts and chats. This makes imo suitable for everyday family calls, group conversations, and international contact across different networks and devices.
