Have you ever tried to make a call only to be met with the frustrating “SIM not provisioned for voice” error? This common issue can leave you unable to make or receive calls, though other phone functions may still work. As a mobile technology expert with over 20 years of experience, I’ve helped countless users resolve this problem. In this comprehensive guide, I’ll explain what causes this error and walk you through the most effective solutions to get your phone working again.
Understanding the “SIM Not Provisioned for Voice” Error
The “SIM not provisioned for voice” error occurs when your SIM card fails to register properly with your carrier’s network for voice services. This can happen for several reasons:
- A new SIM card that hasn’t been fully activated
- Your SIM card has been deactivated by the carrier
- The SIM is not properly inserted in your device
- There’s a temporary network issue
- Your device’s software is outdated
While this error primarily affects voice calls, other services like data and text messaging might still function normally. However, the inability to make calls can be a significant inconvenience, especially in emergency situations.
It’s worth noting that this error is similar to the “SIM not provisioned MM2” error, which also indicates a problem with SIM card registration.
Common Causes of SIM Provisioning Errors
1. New or Unactivated SIM Cards
When you get a new SIM card, it often requires activation before it can fully connect to the network. If you’ve recently switched to a new SIM or carrier, this is likely the cause of your provisioning error.
2. Carrier and Network Issues
Sometimes, the problem lies with your service provider. Server outages, maintenance, or accidental deactivation of your SIM can all lead to provisioning errors. In some cases, you might even receive a “This number is no longer in service” message, which could be related to SIM provisioning issues.
3. Improper SIM Insertion
If your SIM card isn’t seated correctly in its slot, it may not make proper contact with your device, leading to connectivity issues. This can sometimes result in your phone saying “No SIM card”, even when a SIM is present.
4. Device Software Problems
Outdated operating systems or bugs in your phone’s software can sometimes interfere with SIM card recognition and activation.
Initial Troubleshooting Steps
Before diving into more advanced solutions, try these simple fixes that often resolve the “SIM not provisioned for voice” error:
1. Restart Your Device
A simple restart can often work wonders:
- Power off your phone completely
- Wait for about 30 seconds
- Turn your phone back on
This refreshes your device’s connection to the network and can resolve temporary glitches.
2. Toggle Airplane Mode
Enabling and then disabling Airplane mode can reset your network connections:
- Swipe down from the top of your screen to access quick settings
- Tap the Airplane mode icon to turn it on
- Wait for about 30 seconds
- Tap the icon again to turn Airplane mode off
3. Check for Software Updates
Keeping your device’s software up to date is crucial for maintaining proper functionality:
- Go to your phone’s Settings

Advanced Troubleshooting Techniques
If the basic steps don’t solve the problem, try these more advanced solutions:
Reset Network Settings
Resetting your network settings can clear out any misconfigurations:
- Go to your device’s Settings
- Find “Reset” or “General Management“
