⚡Quick answer
Yes. To place or receive calls in Heyo you must have both:
- An active SIM card (the one you registered with Heyo) that has a working voice-calling plan.
- A basic internet connection—Wi-Fi or mobile data—to route and mask each call. Without either element, the call will fail to connect.
1. Minimum prerequisites
• Active SIM card: The physical SIM card registered with your Heyo account must be present in the device you are using.
• Sufficient calling balance: Your SIM card must have an active calling plan for outbound calls.
• Basic internet connection: Wi-Fi or mobile data is needed to initially route the call for masking purposes.
• Up-to-date Heyo app: Install the latest version from Google Play or the App Store.
2. Step-by-step: Fix common calling issues
- Check your SIM card and plan
- Ensure the SIM is properly inserted and active.
- Dial your carrier’s balance code (e.g., *123#) or open the carrier app to confirm voice minutes.
- Verify the correct SIM (dual-SIM phones)
- Go to device Settings → SIM & Network.
- Set the registered SIM as the default line for calls.
- Confirm your internet connection
- Open a browser to test Wi-Fi or mobile data.
- On mobile data, make sure Heyo has data permissions in OS settings.
3. Troubleshooting a suspended account
• If your account has been suspended (for example, due to a payment issue or blacklisting), you will be unable to make calls even if your SIM and internet are active.
• The Heyo app shows a “Suspended” banner; follow on-screen steps to update payment and reactivate.
4. What will NOT work
✖️ A phone without the registered SIM inserted.
✖️ A SIM that has no active calling balance.
✖️ An internet-less environment (airplane mode, poor reception).
