Quick Answer
When your Android phone can send texts but won’t make calls, the problem typically stems from network settings, carrier issues, or specific call-related configurations rather than a complete connectivity failure. Start by checking airplane mode, call barring settings, and VoLTE/Wi-Fi calling options. If basic toggles don’t work, resetting network settings or updating your carrier settings usually resolves the issue without needing professional repair.
Understanding Why Texting Works But Calls Don’t
Text messages and phone calls use different network protocols and pathways, which explains why one can work while the other fails. SMS messages travel through a separate signaling channel that requires minimal bandwidth and doesn’t need the same continuous connection that voice calls demand. Voice calls require either a circuit-switched connection through your carrier’s voice network or a VoIP connection through LTE (Voice over LTE/VoLTE). When something disrupts the voice pathway specifically, texts continue functioning normally because they operate independently.
This distinction matters because it narrows down troubleshooting. You’re not dealing with a complete hardware failure or total signal loss. Instead, the issue likely involves call-specific settings, temporary network glitches, or configuration problems that affect voice services only.
First Steps to Take Immediately
Before diving into complex solutions, run through these quick checks that resolve most calling issues within minutes. Toggle airplane mode on for 10 seconds, then turn it off. This forces your phone to re-establish all network connections and often clears temporary glitches in the voice network registration. Check whether Do Not Disturb is active, as some configurations block incoming calls while allowing texts through. Look at your signal bars to confirm you have network coverage, keeping in mind that even weak signal usually suffices for texts but may fail for calls.
Restart your phone completely. This simple step clears cached network data and resets all communication services. Many calling problems disappear after a fresh boot because it forces Android to re-negotiate network settings with your carrier from scratch.
Call Barring and Call Forwarding Settings
Android phones include call management features that can prevent outgoing or incoming calls without affecting texts. Call barring might be activated accidentally, blocking specific types of calls based on criteria like international numbers or all outgoing calls. Open your Phone app, tap the three-dot menu, select Settings, then look for “Call settings” or “Supplementary services.” Check whether any call barring options are enabled and disable them.
Call forwarding can also create situations where calls appear to fail. If all calls forward to a non-working number or voicemail immediately, you might think your phone isn’t making calls when they’re actually being redirected. In the same call settings menu, verify that call forwarding is either disabled or set to your correct voicemail number.
Network Mode and Carrier Settings
Your phone’s network mode determines which cellular technologies it uses for calls. If set to “2G only” or experiencing issues switching between networks, voice calls may fail while texts still work on the basic 2G connection. Navigate to Settings > Network & Internet > Mobile Network > Preferred Network Type. Ensure it’s set to “5G/4G/3G (auto)” or whatever the recommended automatic setting is for your carrier. This allows your phone to select the best available network for voice calls.
Carrier settings updates contain important configurations for how your phone communicates with your specific provider’s network. Check Settings > System > System Update or Settings > About Phone for any available carrier settings updates. Installing these updates can fix compatibility issues between your phone and recent carrier network changes.
VoLTE and Wi-Fi Calling Complications
Voice over LTE (VoLTE) enables HD voice calls over 4G networks instead of dropping to 3G for calls. When VoLTE malfunctions or your carrier requires it but it’s disabled, calls fail while texts continue working on the data connection. Go to Settings > Network & Internet > Mobile Network and toggle VoLTE on if available. Some phones list this as “Enhanced 4G LTE Mode” or “4G Calling.”
Wi-Fi calling can interfere with regular cellular calls if configured incorrectly. If Wi-Fi calling is enabled but your router has restrictive firewall settings or unstable connectivity, calls might fail while texts use cellular data. Try disabling Wi-Fi calling temporarily to test whether cellular calls work normally. If they do, either fix your Wi-Fi calling setup or keep it disabled.
SIM Card Issues
A partially unseated or dirty SIM card can disrupt voice services while maintaining enough contact for text messaging. Power off your phone, remove the SIM card, inspect it for dirt or damage, clean the gold contacts gently with a dry cloth, and reinsert it firmly. Make sure the SIM card tray clicks completely into place.
SIM cards can also develop faults over time. If your SIM is several years old, contact your carrier for a replacement. Modern SIM cards contain updated security certificates and network configurations that older cards lack, and replacing an aging SIM often resolves mysterious calling problems. Most carriers provide replacement SIMs free at their retail locations.
Resetting Network Settings
When individual troubleshooting steps fail, resetting all network settings provides a comprehensive fix that doesn’t delete personal data. This reset removes all saved Wi-Fi networks, Bluetooth pairings, VPN configurations, and cellular settings, returning everything to factory defaults while preserving your apps, photos, and files.
Find this option in Settings > System > Reset Options > Reset Wi-Fi, Mobile & Bluetooth (exact wording varies by Android version and manufacturer). After the reset completes, your phone will need to reconnect to Wi-Fi and might require you to re-enter your SIM PIN if you have one set. Test calling immediately after the reset, as this resolves the majority of persistent calling issues.
App Permissions and Phone App Data
The Phone app itself needs specific permissions to access your microphone, contacts, and phone functions. If these permissions get revoked accidentally, calls may fail. Go to Settings > Apps > Phone (or Dialer) > Permissions and verify that all necessary permissions are granted, especially “Phone” and “Microphone.”
Clearing the Phone app’s cache can fix corruption in stored data without losing your call history. In the same app settings screen, tap Storage, then “Clear Cache.” Avoid “Clear Data” unless you’re willing to lose call logs and app settings. After clearing the cache, test whether calls work properly.
Carrier Account and Service Issues
Problems on your carrier’s end can restrict voice services while leaving messaging intact. If your account has an overdue balance, some carriers suspend calling privileges but allow texts. Log into your carrier account online or through their app to verify your service status and payment status.
Temporary network outages or maintenance in your area might affect voice services differently than text services. Check your carrier’s service status page or contact customer support to confirm there are no known issues in your location. If tower maintenance is underway, the problem will resolve automatically once work completes.
Third-Party App Interference
Call-blocking apps, VPN services, and security apps sometimes interfere with the native Phone app. Boot your phone into Safe Mode, which disables all third-party apps temporarily. To enter Safe Mode, press and hold the power button, then tap and hold “Power off” until you see the Safe Mode prompt. If calls work in Safe Mode, a third-party app is causing the problem. Uninstall recently added apps one by one to identify the culprit.
When to Contact Support or Consider Hardware
If none of these solutions work, the issue might involve hardware damage to your phone’s antenna or cellular radio, though this is less common than software problems. Water damage, drops, or manufacturing defects can impair the voice radio while leaving other functions operational. Schedule service with your phone manufacturer if your device is under warranty.
Contact your carrier’s technical support as a final step. They can run diagnostics on their network end, reprovision your account, or identify whether your phone’s IMEI is properly registered in their system. Sometimes carrier-side resets fix problems that no amount of phone-side troubleshooting can address.
Frequently Asked Questions
Can I still make emergency calls if my phone won’t make regular calls?
Emergency calls function differently than regular calls and work even without an active service plan or SIM card. Your phone will attempt emergency calls on any available carrier network, not just your own. If you cannot make emergency calls either, this indicates a more serious hardware or software problem requiring immediate professional attention.
Why does my phone say “mobile network not available” only when calling?
This message typically indicates your phone cannot access the voice network specifically, even though it maintains a data connection for texts. The issue usually stems from incorrect network mode settings, disabled VoLTE when your carrier requires it, or your account lacking voice service provisioning. Reset network settings and verify your account status with your carrier.
Will a factory reset fix my calling problem?
A factory reset will likely fix software-related calling issues, but it should be your last resort since it erases all data, apps, and settings. Try resetting network settings first, as this resolves most calling problems without data loss. Only perform a factory reset after backing up everything important and confirming that simpler solutions have failed.
How do I know if my SIM card is faulty?
Test your SIM in another compatible phone if possible. If calling works in a different device, your phone has the problem. If calling fails in multiple phones with the same SIM, the SIM card itself is faulty. Physical damage, visible cracks, or a SIM that’s more than three years old often needs replacement regardless of whether it shows obvious problems.
Can a software update cause calls to stop working?
Software updates occasionally introduce bugs that affect calling, especially immediately after major Android version upgrades. Check your phone manufacturer’s support forums to see if others report similar issues after the same update. Manufacturers typically release patches quickly for widespread calling problems. You might also try clearing the Phone app cache and resetting network settings after any major update.
Does this problem mean my phone is permanently damaged?
Most calling issues while texting still works are software or configuration problems, not permanent hardware damage. The fact that your phone maintains network connectivity for texts proves the radio hardware functions. Systematic troubleshooting resolves the vast majority of these cases without repair or replacement. Only pursue hardware service after exhausting all software solutions.
Why can I receive calls but not make them?
When you can receive calls but outgoing calls fail, check whether call barring is enabled specifically for outgoing calls, verify that you have sufficient account credit if on prepaid service, and confirm your phone isn’t in a restricted dialing mode. Some phones have “Fixed Dialing Number” features that limit outgoing calls to approved contacts only. Check your Phone app settings under Call Settings or Security to disable any restrictions.
