# 4 Fixes for Android Phone Not Receiving or Making Calls *Published:* 2026-01-13 *Author:* Farzan Hussain When a 2026 Android phone stops ringing or refuses to dial out, the cause is rarely the radio hardware itself. The four likely culprits are Do Not Disturb running in the background, a Wi-Fi Calling fallback that is silently failing, a SIM or eSIM provisioning issue at the carrier, and a stale carrier configuration that needs a refresh. Run these checks in order on Pixel 9 or Galaxy S25 hardware. The same fixes apply to mid-range Android 15 devices, since the underlying telephony stack has not changed meaningfully since Android 14. ### TL;DR **The pick:** Toggle Airplane mode on, wait fifteen seconds, toggle off. Resolves roughly forty percent of cases. **Runner-up:** If calls still fail, dial \*#\*#4636#\*#\* (most Androids), choose Phone information, and force Set preferred network type to a mode your carrier supports (5G NSA + LTE works almost everywhere). **Skip if:** Skip the home fixes if no other device on your account can place calls. That points to a carrier outage; check the carrier status page first. Confirm it is not Do Not Disturb or a call block ------------------------------------------------ Pull down the quick settings panel and check for the DND icon. On Pixel and Galaxy phones, Do Not Disturb silences ringing entirely unless a contact is in your starred list. Tap the icon off and try a test call. Open the Phone app, three-dot menu, Settings, Blocked numbers, and confirm the caller is not on the list. Also check Spam and Call Screen on Pixel, since aggressive spam filtering occasionally swallows legitimate numbers. Reset the radio stack --------------------- Toggle Airplane mode on, wait fifteen seconds, then off. This re-runs the LTE/5G attachment handshake and frequently restores service. Reboot the phone next if calls still fail; this clears the carrier-config cache too. If you use Wi-Fi Calling, turn it off in Settings, Network and internet, SIMs, then back on. A stale Wi-Fi Calling registration is a common cause of calls landing in voicemail without ringing the phone. Refresh the carrier profile --------------------------- On Pixel, dial \*#\*#4636#\*#\*, Phone information, and tap Refresh carrier settings if the option exists. On Galaxy, open Settings, About phone, Software information, Service provider software version, and tap Update. This pulls a current APN and IMS profile from the carrier. If the option is absent on your device, remove and reinsert the physical SIM, or in the eSIM case, go to Settings, Network and internet, SIMs, tap the eSIM, and use the carrier app to reactivate. Call the carrier as the last step --------------------------------- If none of the above works, the issue is server-side. Call the carrier from another phone and ask them to reset your line provisioning and re-push the eSIM profile if applicable. Verizon, T-Mobile, AT&T, and the major UK and EU carriers all have a tier-one tool for this. While on the line, ask them to confirm VoLTE and VoNR are enabled on your account. A growing share call failures come from accounts that never had VoNR flipped on after a SIM swap. The setup, step by step ----------------------- 1. 1#### Disable DND and check blocklists Quick settings, DND off. Phone app, Settings, Blocked numbers, review. 2. 2#### Cycle airplane mode and reboot Airplane on for 15 seconds, off. Reboot if still failing. 3. 3#### Toggle Wi-Fi Calling Settings, Network and internet, SIMs, Wi-Fi Calling off then on. 4. 4#### Refresh carrier settings Dial \*#\*#4636#\*#\*, Phone information, Refresh carrier settings, or reseat the SIM. 5. 5#### Call the carrier Ask for a line reset and confirmation that VoLTE and VoNR are active. FAQ --- ### Why does my phone vibrate but not ring? Almost always a ringtone or volume issue, not a call issue. Check Settings, Sound and vibration, Ring volume. ### Calls go straight to voicemail. What now? Toggle Wi-Fi Calling off and try a test call. A stale Wi-Fi Calling registration is the most common cause. ### eSIM stopped working after a software update. Fix? Settings, Network and internet, SIMs, tap the eSIM, and use the carrier app to reactivate. Some updates invalidate the profile. ### Can I reset network settings without losing data? Yes. Settings, System, Reset options, Reset mobile, Wi-Fi and Bluetooth. It only clears network configs, not [apps](https://bestforandroid.com/best/apps-android/ "Best Apps Category") or files. Bottom line ----------- Call failures on Android are almost always a software or carrier-side issue, not broken hardware. Cycle the radio, refresh the carrier profile, and verify VoLTE and VoNR are enabled on the account. If the line is genuinely dead, the carrier needs to push a fresh provisioning record from their end. #### How we put this guide together The picks and steps in this guide reflect what works on current Android builds. Our editors test apps on Pixel 8a and Galaxy S24 hardware running Android 15 and Android 16, cross-check against vendor documentation, and update each guide when behavior changes. ### Related on BestForAndroid - [How to Fix an Android Phone That Will Not Make or Receive Calls](https://bestforandroid.com/phone-not-making-receiving-calls/) - [How to Fix an Android Phone That Keeps Freezing](https://bestforandroid.com/fix-phone-freezing-problems/) - [Remove Ransomware From an Android Phone (Step by Step)](https://bestforandroid.com/remove-ransomware-from-android-phone/) - [Stop Popup Ads When You Unlock Your Android Phone (The Real Fix)](https://bestforandroid.com/ads-pop-up-on-unlock-android/)
