Fix Android Not Making Calls But Can Text

If your Android phone can send and receive text messages but won’t make or receive calls, the problem is almost always in the cellular voice network settings, not the phone’s hardware. This guide walks you through the most common fixes, from a simple restart to resetting your network settings, and explains why texting works while calling doesn’t.

Why Texting Works But Calling Doesn’t

Text messages (SMS/MMS) and voice calls use different parts of your carrier’s network, even though both go through the cellular radio. SMS is a control-channel service that can work even when the voice channel is blocked or misconfigured. Voice calls, especially on 4G LTE and 5G networks, rely on VoLTE (Voice over LTE) or VoNR (Voice over 5G New Radio). If VoLTE is disabled, not provisioned by your carrier, or the network doesn’t recognize your phone’s IMEI, you’ll see full signal bars and can text, but calls fail immediately or drop. Another common cause is a software glitch in the Phone app or a temporary network registration error.

Before You Start: Quick Checks

These take less than a minute and solve a surprising number of cases:

• Check for a red “No SIM” icon in the status bar. If present, power off, remove the SIM, and reinsert it.
• Try calling a different number (landline or another mobile) to rule out a specific contact issue.
• Check if the person you’re calling is also on a network that’s down — but if you can’t call anyone, it’s your phone.
• Look for an “Emergency calls only” message — that means the phone isn’t registered on your carrier’s network.

Fix 1: Toggle Airplane Mode

This forces your phone to re-register with the nearest cell tower. Swipe down from the top of the screen to open Quick Settings, tap the Airplane mode icon to turn it on, wait 10–15 seconds, then tap it off. After the signal bars reappear, try making a call. If that fails, do a full restart: press and hold the power button, tap Restart, and wait for the phone to boot completely.

Fix 2: Check and Enable VoLTE (Voice over LTE)

VoLTE is what allows calls to go over the data network. If it’s off, your phone may fall back to 2G/3G, which many carriers have shut down. To check:

1. Open Settings → Network & internet (or Connections on Samsung).
2. Tap Mobile network (or SIM & network).
3. Look for VoLTE or HD Voice — if there’s a toggle, make sure it’s on.
4. If you don’t see the toggle, your carrier may have it permanently enabled, or your phone model doesn’t support it on that network.

If VoLTE is on but calls still fail, try turning it off, restarting, then turning it back on. This sometimes re-registers the service.

Fix 3: Reset Network Settings

This clears saved Wi-Fi networks, Bluetooth pairings, and cellular settings, but does not delete your photos, contacts, or apps. It’s safe to try. The exact path varies by manufacturer:

• Stock Android (Pixel): Settings → System → Reset options → Reset Wi-Fi, mobile & Bluetooth.
• Samsung: Settings → General management → Reset → Reset network settings.
• OnePlus: Settings → System → Reset options → Reset Wi-Fi, mobile & Bluetooth.

After resetting, you’ll need to reconnect to Wi-Fi and re-pair Bluetooth devices. Then test a call.

Fix 4: Update Your Phone and Carrier Settings

Carriers push small configuration updates (called PRL or carrier services) that tell your phone how to connect to their towers. To check for updates:

1. Go to Settings → About phone → Software updates (or System updates). Install any pending system update.
2. On Samsung, go to Settings → Connections → Mobile networks → Carrier settings and tap Update if available.
3. Also check the Google Play Store for updates to the Phone app and Carrier Services app. Open Play Store, search for “Phone” and “Carrier Services,” and update if needed.

Fix 5: Clear the Phone App’s Cache and Data

A corrupted cache in the Phone app can cause calls to fail while texts work fine. Clearing it won’t delete your contacts or call history (those are stored separately).

1. Open Settings → Apps (or App management).
2. Tap Phone (or Dialer).
3. Tap Storage & cache → Clear storage (or Clear data).
4. Confirm, then restart your phone.

Note: On some phones, clearing data may reset your call forwarding settings or speed dials, so you’ll need to set those again.

Fix 6: Reinsert or Replace the SIM Card

If the above fail, power off the phone, remove the SIM card tray, and inspect the SIM for any visible damage. Clean the gold contacts with a soft, dry cloth and reinsert. If you have another phone available, put the SIM in that phone and try calling — if it fails there too, the problem is the SIM or your account, not your phone. In that case, contact your carrier to check if your line is provisioned correctly for voice service.

When to Contact Your Carrier

If you’ve tried all the steps above and still can’t call, the issue is likely on the carrier side. Tell them:

• Your phone can text but not call.
• VoLTE is enabled (if it was).
• You’ve already reset network settings.

They can check if your line has a voice service block, if your IMEI is whitelisted, or if there’s an outage in your area. Sometimes they need to refresh your network profile or send a new SIM.

Frequently Asked Questions

Why does my Android say “Not registered on network” when I try to call?

This means your phone can’t connect to your carrier’s voice network. It often happens after a software update or when you’ve been in an area with poor coverage. Toggle Airplane mode, restart, or manually select your carrier in Settings → Network & internet → Mobile network → Network operators.

Can a dead battery cause call failure?

No, but a very low battery can cause the phone to drop calls or fail to initiate them if the system prioritizes power saving. Make sure your battery is above 20% and test again.

Will resetting network settings delete my contacts?

No. Network settings only affect Wi-Fi passwords, Bluetooth pairings, and cellular configurations. Your contacts, photos, and apps are untouched.

Why does my phone work on Wi-Fi calling but not on cellular?

Wi-Fi calling uses your internet connection, so it bypasses the cellular voice network entirely. If Wi-Fi calling works but cellular doesn’t, the problem is with your carrier’s cellular voice service, not your phone’s speaker or microphone. Check if VoLTE is enabled and contact your carrier.

Do I need to back up before trying these fixes?

Most fixes are safe, but clearing the Phone app’s data may reset call forwarding settings. It’s always a good idea to back up your contacts and important data before making any changes, just in case.

What if I have a dual-SIM phone?

Make sure the SIM you’re trying to call from is set as the default for calls. Go to Settings → Network & internet → SIM cards and check which SIM is selected for calls. Also ensure that SIM has voice service enabled.
