Default APN Settings

Usually, your Oi Brazil SIM card comes with pre configured APN settings, meaning you shouldn’t need to do anything. However, if you encounter issues, checking these settings is helpful. To find them:

1. Go to your device’s settings.
2. Locate “Mobile networks” or a similar option.
3. Find the “Access Point Names” section.
4. Check for an APN starting with “oi” or “oibrasil”.

Manual APN Configuration

If your device lacks the correct APN or you have persistent connection problems, manual configuration might be necessary. Here’s a general guide:

1. Access your device’s APN settings as mentioned above.
2. Tap “Add APN” or “New APN”.
3. Input the correct Oi Brazil APN information. Obtain this from Oi Brazil’s website or customer support.
4. Save the new APN and set it as default.

3 Basic Troubleshooting Steps

1. Verify APN Configuration

The first step in troubleshooting APN issues is to ensure that your phone’s APN settings match those provided by Oi Brazil. Here’s what you need to do:

1. Go to your phone’s settings: Mobile Networks > Access Point Names.
2. Check that the APN settings are as follows:
   • Name: Oi Internet
   • APN: gprs.oi.com.br
   • Authentication Type: CHAP or PAP
   • APN Type: default

I remember a time when I couldn’t access the internet on my Samsung Galaxy S21. I checked my APN settings and realized that the Authentication Type was set to “None” instead of “CHAP or PAP”. Changing this setting resolved my connectivity issue.

2. Reset APN Settings

If you’ve made changes to your APN settings and are experiencing issues, resetting to the default configuration provided by Oi Brazil can often solve the problem. Look for a “Reset to Default” option in your phone’s APN settings menu and tap on it to restore the default settings.

3. Restart Your Device

Sometimes, a simple restart can resolve connectivity issues by re-establishing a proper network connection and applying the new APN settings effectively. If you’re experiencing problems with your Oi Brazil connection, try restarting your device to see if it resolves the issue.

7 Advanced Troubleshooting Tips

1. Manually Configure DNS Settings

If you’re experiencing slow or unstable internet connections, manually setting your phone’s DNS (Domain Name System) can help improve connectivity. Try using Oi Brazil’s recommended DNS servers:

• Primary DNS: 200.222.222.222
• Secondary DNS: 201.222.222.222

To change your DNS settings, go to your phone’s Wi-Fi settings, long-press on the connected network, and select “Modify Network.” Expand the “Advanced Options” and change the “IP Settings” to “Static.” Enter the recommended DNS server addresses in the “DNS 1” and “DNS 2” fields.

2. Disable Data Saver Mode

Some devices have a built-in “Data Saver” or “Low Data Mode” that can interfere with APN settings. To ensure optimal connectivity, try disabling this feature:

• On Android: Go to Settings > Network & Internet > Data Saver and turn it off.
• On iOS: Go to Settings > Mobile Data > Low Data Mode and turn it off.

3. Check for Conflicting Network Settings

If you’re using a dual-SIM device or have multiple network configurations, conflicts between settings can cause APN issues. Try removing any unused or unnecessary network settings and ensure that your Oi Brazil SIM is set as the preferred network.

4. Modify APN Protocol and Roaming Protocol

In some cases, changing the APN Protocol and Roaming Protocol can improve connectivity. Try the following settings:

• APN Protocol: IPv4/IPv6
• Roaming Protocol: IPv4

These settings can be found under the “Bearer” or “Advanced” options in your APN settings menu.

5. Enable/Disable Mobile Data Always Active

Some devices have a “Mobile Data Always Active” option that can affect APN performance. Try toggling this option on or off to see if it improves connectivity:

• On Android: Go to Settings > Developer Options > Mobile Data Always Active.
• On iOS: This option is not available.

6. Clear System Cache

Clearing your device’s system cache can help resolve APN-related issues caused by corrupted or outdated cache files. To clear the system cache:

• On Android: Turn off your device, press and hold the Volume Down and Power buttons simultaneously until the Android logo appears, then use the volume buttons to navigate to “Wipe Cache Partition” and select it using the Power button.
• On iOS: This option is not available.

7. Contact Oi Brazil Support

If you’ve tried all the above troubleshooting steps and are still experiencing issues with your Oi Brazil APN settings, it may be worth contacting Oi Brazil support. They can provide further assistance and may be able to identify any network-specific issues or outages that could be affecting your connectivity.

When I was traveling in Rio de Janeiro, I encountered a persistent issue with my mobile data not working, even though my APN settings were correct.
