Top 10 Reasons International Calls Fail (and Fixes)

1. No or Poor Internet Connection

Most common cause — VoIP calls need stable internet.

Fixes:

• Switch to strong Wi-Fi (avoid public/hotspot if possible)
• Move closer to router or use 5G if mobile data
• Try offline mode: Use local access number instead (see related article)
• Test speed: Need at least 100–200 kbps upload/download for voice

2. Low or Zero Balance/Credit

Calls stop when balance reaches zero.

Fixes:

• Check balance in app → Wallet
• Add credit (minimum $5 recommended)
• Enable auto-recharge to prevent interruptions

3. Wrong Number Format / Country Code Missing

Many failures happen because country code (+1, +44, etc.) is forgotten.

Fixes:

• Always include + and country code (e.g., +1 555 123 4567)
• Use contacts saved in MyLine — it auto-formats

4. Recipient's Number Blocked or Invalid

Some countries block VoIP, or number is wrong/disconnected.

Fixes:

• Try calling a different number to test
• Ask recipient to call you back (test incoming)
• Check MyLine status page or support for country restrictions

5. Firewall, VPN, or Network Restrictions

Corporate/school Wi-Fi, VPNs, or carrier blocks can stop VoIP.

Fixes:

• Disable VPN temporarily
• Switch to mobile data or different Wi-Fi
• MyLine uses ports 5060/5061 — ask IT to allow if needed

6. App Permissions Not Granted

Microphone/camera blocked on Android/iOS.

Fixes:

• Go to phone Settings → Apps → MyLine → Permissions → Enable Microphone (and Camera for video)
• Restart app after granting

7. Outdated App Version

Bugs in old versions cause failures.

Fixes:

• Update MyLine in Google Play Store / App Store
• Restart phone after update

8. Temporary Server or Carrier Issue

Rare, but MyLine or your carrier may have brief outages.

Fixes:

• Wait 5–10 minutes and retry
• Check MyLine status page (in app or website)
• Contact support via in-app chat

9. Echo, Delay, or One-Way Audio

Feels like "failed" due to poor quality.

Fixes:

• Switch to Wi-Fi (better than mobile data)
• Use headset/earphones to reduce echo
• Enable "Data Saver" mode in settings for lower bandwidth

10. Recipient's Phone Off or Do Not Disturb

Common but often overlooked.

Fixes:

• Send a text first to confirm
• Try calling again later
