There can be several reasons why a phone can access the internet but cannot make or receive calls. Below are some common causes and potential solutions:

### 1. **SIM Card Issues**

- **Faulty SIM Card**: If your SIM card is damaged or not properly seated, it might affect your ability to make calls while still allowing internet access[5].

- **Solution**: Remove your SIM card, inspect it for damage, and reinsert it properly. If the problem persists, consider getting a replacement SIM card.

### 2. **Network or Account Issues**

- **Account Restrictions**: Issues with your mobile network account, such as unpaid bills or account restrictions, can block calling services while still permitting data usage[8].

- **Solution**: Contact your service provider to ensure your account is in good standing and that there are no restrictions or issues.

### 3. **Device Settings**

- **Call Settings**: Incorrect call settings could be the culprit. For instance, if you have settings that prefer internet calling apps or have the "Use Internet Calling" option enabled, it might interfere with regular calls[2].

- **Solution**:

- Navigate to the Phone app.

- Tap on Menu -> Call settings -> Internet Call Settings.

- Ensure that "Only Internet Calls" is not selected.

### 4. **Antenna or Hardware Issues**

- **Radio Antenna Problems**: The antenna responsible for voice calls might be damaged or improperly connected[2].

- **Solution**: Check for physical damage or connections related to the phone’s hardware. It might require professional inspection if the issue is internal.

### 5. **Software Issues**

- **Software Glitches**: Software bugs or outdated firmware can cause calling functions to malfunction while leaving internet capabilities unaffected[8].

- **Solution**:

- Restart your phone.

- Ensure your phone's software is up-to-date.

- Reset network settings: Settings -> General Management -> Reset -> Reset Network Settings.

### 6. **Airplane Mode**

- **Accidentally Enabled**: If airplane mode is accidentally enabled, it will disable call functions while Wi-Fi remains active for internet access[8].

- **Solution**:

- Go to Settings.

- Ensure airplane mode is turned off.

- Toggle airplane mode on and off to refresh the connection.

### Summary

To troubleshoot a phone that can access the internet but not make calls, check the following:

- SIM card integrity and placement.

- Account status with your service provider.

- Call settings and preferences.

- Physical condition of the antenna and hardware.

- Software updates and potential glitches.

- Airplane mode status.
