7 imo alternatives worth switching to in 2026
imo is free, works on weak networks, and supports international video calls in more than 170 countries. The catch is the ad load. Reviews on Trustpilot, Google Play, and the App Store consistently flag ads that cover the screen after calls, full-page interstitials when you exit, and an advertising identifier that imo collects by default for ad personalization. The app also disrupts Bluetooth audio for some users and continues ringing after declined calls until the phone is rebooted.
If the ads, the call quirks, or the data collection finally tipped you over, this guide covers the seven best imo alternatives we tested in 2026. Each one solves a specific imo weakness, whether that’s ad-free calling, default end-to-end encryption, or reliable group video meetings.
| App | Best for | Free plan | Starting price | Standout feature |
|---|---|---|---|---|
| Mainstream replacement | Yes | Free | E2E by default, 32-person calls | |
| Telegram | Group calls and channels | Yes | Free | 200,000-member groups |
| Viber | International calls | Yes | Free | Viber Out to landlines |
| Signal | Privacy-first calling | Yes | Free | Sealed Sender metadata defense |
| JusTalk | Family video chat | Yes | Free | Doodle-on-video, Kids mode |
| Google Meet | Quick group meetings | Yes | Free | 100 participants, 60 min free |
| Zoom | Long meetings and webinars | Yes | $14.99/mo Pro | 30+ hour meetings on Pro |
Why people leave imo
The ads are aggressive. Full-page video ads play when you open the app. Banner ads sit on the call screen. Interstitials appear after calls end and after you decline calls. Users on Trustpilot describe the experience as “unusable without paying for a quieter alternative.”
Bluetooth and call handling bugs persist. Multiple reviewers report imo disrupting paired Bluetooth devices when a call comes in, music continuing during calls, and the app ringing past a declined call until the device reboots.
Tracking by default. imo collects an advertising identifier, IP address, and device model from launch and uses them to deliver tailored ads. Data sharing with third parties is disclosed in the privacy policy and not opt-in.
Battery and storage drain. imo runs background services for chat sync and call delivery, which consume notable battery on older Android devices. Cached call clips and stickers can grow into multi-gigabyte storage hits if not cleared manually.
The alternatives
WhatsApp — best mainstream replacement
WhatsApp is the obvious swap for users who want imo’s free messaging and video calling without the ads. Group calls go up to 32 participants, every chat and call is end-to-end encrypted with the Signal Protocol, and the app has 2 billion users across 180 countries, which is roughly the same global reach imo claims.
For one-to-one and small group video, WhatsApp vs. imo isn’t a close fight. The interface is cleaner, there are no ads, and call quality on weak networks is competitive thanks to adaptive bitrate. WhatsApp also supports voice messages, document sharing up to 2 GB, and Communities for organizing larger groups by topic.
Where it falls short: Meta owns WhatsApp and collects metadata (who you message, when, from where) even though message content stays encrypted. Group calls cap at 32 participants, far below Zoom or Meet for larger team meetings. There’s no PSTN dialing.
Pricing:
- Free: messaging, voice, video, group calls, communities
- vs. imo: free for both; WhatsApp wins on ads (none) and default E2E, imo offers VoiceClub which WhatsApp doesn’t
Migrating from imo: No importer for chat history. Sync your phonebook and contacts already on WhatsApp will surface immediately. Your imo group chats need to be recreated.
Bottom line: Pick WhatsApp if you want the smoothest, ad-free swap from imo. Skip it if you specifically need imo’s VoiceClub or live voice rooms.
Telegram — best for group calls and channels
Telegram brings free group video calls for up to 1,000 viewers (with 30 active speakers), unlimited cloud storage, and the broadest channel and bot ecosystem of any messaging app. For users who liked imo’s group features but wanted more breadth, Telegram is the upgrade.
Voice Chats inside groups effectively replace imo’s VoiceClub. Channels handle one-to-many broadcasting in a way imo doesn’t really attempt. The desktop and web clients are first-class, not afterthoughts.
Where it falls short: Default chats and group calls are not end-to-end encrypted; only Secret Chats are E2E and they don’t cover groups or video calls. OCCRP reporting in 2024 documented infrastructure ties to Russian-affiliated operators. Scam channels and crypto malware remain a problem.
Pricing:
- Free: messaging, voice, video, group calls, channels
- Telegram Premium: monthly subscription for higher upload limits and faster downloads
- vs. imo: free for both; Telegram wins on group size and bot ecosystem, imo offers PSTN-style dialing on weak networks that Telegram doesn’t match
Migrating from imo: No importer. Sync your phonebook, recreate group chats by inviting people via deep links, and use Voice Chats inside groups for the live-room experience.
Bottom line: Pick Telegram if your imo use is mostly groups and broadcast-style sharing. Skip it if default end-to-end encryption matters.
Viber — best for international calls
Viber is the closest direct match for imo’s international-calling angle. Free voice and video calls between Viber users, end-to-end encrypted by default, work in 190-plus countries on weak connections. Viber Out adds paid per-minute calling to landlines and mobile numbers, so you can reach contacts who never installed any messaging app.
For users who picked imo specifically to call family abroad, Viber vs. imo wins on quality and on the missing landline option. Communities scale to a billion members in theory; group voice and video calls handle up to 50 active participants. Stickers, GIFs, and basic chat features all work without an ad layer in most regions.
Where it falls short: Viber shows ads in some regions, particularly Eastern Europe and parts of Asia. The app interface is heavier than Signal or WhatsApp, with games, shopping, and sticker-store tabs cluttering the navigation. Rakuten ownership means corporate data flows back to a Japanese parent company.
Pricing:
- Free: messaging, voice, video, group calls
- Viber Out: per-minute international rates to landlines and mobile, paid as you go
- vs. imo: free for both; Viber wins on default E2E and PSTN dialing, imo wins on the absence of ads in some Viber regions
Migrating from imo: Viber syncs your phonebook automatically. Contacts already on Viber surface immediately. Group calls need to be set up fresh.
Bottom line: Pick Viber if you make international calls and want PSTN dialing as a backup. Skip it if seeing ads in any region rules a messenger out for you.
Signal — best for privacy-first calling
Signal is the cleanest privacy upgrade from imo. Every chat, voice call, video call, and group call is end-to-end encrypted by default. Signal stores almost no metadata, only your phone number and last connection date. There are no ads, no advertising identifier, and no data sharing.
For users leaving imo specifically because of ad tracking, Signal vs. imo is the strongest contrast on this list. Group calls handle up to 50 participants, screen sharing works on desktop, and call quality is reliable on weak connections thanks to adaptive bitrate.
Where it falls short: Signal still requires a phone number to register. Group sizes top out at 1,000 chat members, smaller than Telegram or Viber. Discovery is essentially zero, you bring your own contacts. There’s no PSTN dialing, no channels, and no public discovery.
Pricing:
- Free: every feature, no ads, no upsell
- vs. imo: free for both; Signal wins on privacy and no ads, imo wins on cross-platform discoverability
Migrating from imo: No importer. Verify your phone number, share your Signal link with contacts, and let people install. The lack of bots, channels, and stickers is the trade-off.
Bottom line: Pick Signal if your reason for leaving imo is ads and tracking. Skip it if you need broad discovery or large public groups.
JusTalk — best for family video chat
JusTalk is built specifically for family video calls and group video chat with friends, which is much of what imo is actually used for. The app is free, has no full-screen ads on the call surface, and includes a Kids mode that limits the contact list to approved family members. Doodle-on-video, fun filters, and group video chat for up to 50 people round out the feature set.
For users who picked imo for kid-friendly family calls, JusTalk vs. imo is a notable upgrade on usability. The interface is bright, the contact list is simple, and the Kids version (separate app) is one of the few mainstream messaging apps that explicitly targets younger users with parental controls.
Where it falls short: JusTalk is smaller than the giants on this list. If your contacts aren’t already on it, you have to convince each person to install. The privacy posture is weaker than Signal or Threema; the app is closed-source and the privacy policy permits broader data use than the encrypted-messenger camp.
Pricing:
- Free: full messaging, voice, video, group calls
- JusTalk Premium: optional monthly subscription for HD video and ad-free experience in some regions
- vs. imo: free for both; JusTalk wins on kid-safe modes and a cleaner call surface, imo wins on raw user count
Migrating from imo: Sync contacts and JusTalk surfaces existing users automatically. Group chats need to be recreated.
Bottom line: Pick JusTalk if family video is the core use case and you want a cleaner call screen than imo. Skip it if you need the largest possible contact network.
Google Meet — best for quick group meetings
Google Meet is bundled into every Google account, which means most contacts already have it without installing anything new. Free meetings hold 100 people for up to 60 minutes per session, with HD video, captions in 50-plus languages, and screen sharing. For ad-hoc work meetings or family video calls scheduled through Google Calendar, Meet vs. imo is a faster, cleaner experience.
The app handles lossy connections well thanks to Google’s network engineering, supports background blur and noise cancellation on Android, and integrates tightly with Gmail and Calendar so meeting links are one tap away. Live captions are useful for accessibility and for noisy environments.
Where it falls short: The 60-minute cap on free meetings forces a reconnect for longer calls. The free tier doesn’t include cloud recording, breakout rooms, or polls. Google Meet vs. imo on chat is a one-sided fight, Meet is meeting-focused, not a messenger.
Pricing:
- Free: 100-participant meetings up to 60 minutes
- Google Workspace: from $7/user/month for longer meetings, recording, and breakout rooms
- vs. imo: free for both at the basic tier; Meet wins on meeting quality, imo wins on persistent chat
Migrating from imo: Schedule meetings via Calendar and share the link with contacts. There’s no chat history to migrate; Meet is built around meetings, not group chat archives.
Bottom line: Pick Google Meet for scheduled or impromptu meetings. Skip it if you wanted a true imo replacement that lives in your chat list every day.
Zoom — best for long meetings and webinars
Zoom is the most reliable choice when meetings need to run longer than an hour or include 50-plus participants. The free tier handles 100 people for 40 minutes, and paid tiers extend to 30-hour meetings, 1,000 participants, and full webinar tooling with registration pages and Q&A.
For users who pushed imo into work-meeting territory and ran into call quality limits, Zoom vs. imo is a clear upgrade. Recording, transcripts, virtual backgrounds, breakout rooms, and polls are all production-grade. The mobile app handles lossy networks well thanks to Zoom’s media engine.
Where it falls short: Zoom is meeting-first, not messenger-first. Persistent group chat is weak compared to imo’s day-to-day messaging. The free tier’s 40-minute cap is annoying for casual hangouts. Privacy headlines around 2020 still trail Zoom; current encryption is solid for paid tiers but not on by default.
Pricing:
- Free: 100-participant meetings up to 40 minutes
- Pro: $14.99/mo for 30-hour meetings and cloud recording
- Business: $21.99/mo for 300 participants and SSO
- vs. imo: free at the basic tier; Zoom wins on meeting depth, imo wins on always-on messaging
Migrating from imo: Set up a Zoom account and schedule meetings via the app or Outlook/Google Calendar. There’s no chat history transfer; Zoom Team Chat is separate from imo and would need to be set up fresh.
Bottom line: Pick Zoom for serious meetings or webinars. Skip it if you wanted a chat-first imo replacement.
How to choose
Pick WhatsApp for the smoothest swap from imo. The reach is comparable, ads are absent, and E2E is the default.
Pick Telegram if you used imo for groups, channels, or one-to-many broadcasts.
Pick Viber if international calls and PSTN dialing are why you opened imo in the first place.
Pick Signal if ads and tracking pushed you out and privacy is the priority.
Pick JusTalk if kid-friendly family video calls were your main imo use case.
Pick Google Meet for short scheduled meetings, especially if your contacts use Gmail.
Pick Zoom for long meetings, webinars, or 50-plus-participant calls.
Stay on imo if VoiceClub voice rooms are the specific feature keeping you there. None of the alternatives match that exact format.
FAQ
Is WhatsApp better than imo for video calls?
For one-to-one and small group video, yes. WhatsApp video calls are end-to-end encrypted by default, the app shows no ads, and call quality on weak networks is competitive. imo wins only on raw number of users in a few specific regions.
Can I import my imo chat history into another app?
No alternative on this list reads imo’s backup format. Open imo, tap a chat, choose Export, and save messages as text. From there you can keep an archive locally; none of the other apps will ingest it.
What is the cheapest imo alternative?
WhatsApp, Telegram, Signal, Viber, JusTalk, and Google Meet’s basic tier are all free. Among them, WhatsApp and Signal show no ads at any tier, which is the most direct cost contrast with imo’s ad-heavy free tier.
Is there a free video calling app with no ads?
Yes. WhatsApp, Signal, and Telegram (in most regions) show no ads on the call screen. JusTalk is free with optional ad-free upgrades in some regions.
Does imo collect my data?
imo collects an advertising identifier, IP address, device model, user settings, and call metadata by default, and uses that data for personalized ads. The privacy policy permits sharing with third parties. Calls themselves are end-to-end encrypted, but the app’s metadata footprint is large.
What replaces imo’s VoiceClub?
Telegram Voice Chats inside groups are the closest equivalent: live audio rooms tied to a group with a host and listener model. Discord Stage Channels work for larger audio events. Neither is identical, but both cover the live-room use case.
