How to Fix Emergency Calls Only Issue

by

The “Emergency Calls Only” message appears when your phone cannot connect properly to your mobile network. When this happens, you may not be able to make normal calls, send SMS, or use mobile data, except emergency services.

In Nigeria, users on networks such as MTN Nigeria, Airtel Nigeria, Globacom, and 9mobile may see this issue due to weak signal, SIM problems, or incorrect network settings.

This guide explains how to fix it step by step.

What Causes “Emergency Calls Only” Issue?

Common causes include:

  • Weak or no network signal
  • SIM card not detected properly
  • Airplane mode enabled
  • Network outage in your area
  • Incorrect network selection
  • Damaged SIM card

Step 1: Restart Your Phone

A restart refreshes your network connection.

Steps:

  • Turn off your phone
  • Wait 20–30 seconds
  • Turn it back on

This often restores normal network service.

Step 2: Check Signal Strength

If you are in a low coverage area:

  • Move outdoors
  • Go near a window
  • Change location

Signal may vary depending on your provider like MTN Nigeria or Airtel Nigeria.

Step 3: Turn Airplane Mode On and Off

This forces a network refresh.

Steps:

  • Turn on Airplane Mode
  • Wait 20–30 seconds
  • Turn it off again

Your phone will reconnect to available networks.

Step 4: Remove and Reinsert SIM Card

SIM misplacement can trigger this issue.

Steps:

  • Turn off your phone
  • Remove SIM card
  • Clean it gently
  • Reinsert properly
