I understand that you are encountering an issue with your unlimited data subscription. The message you received states that you can only subscribe to the offer once and suggests checking out the GigaLife App for more promotions and points redemption. Here are a few steps you can take to address this issue:
1. Check your current subscription: Make sure that your unlimited data subscription has not expired yet. Dial *123# or check your balance through the GigaLife App to verify your subscription status.
2. Contact customer support: If your subscription is still active, but you are unable to use the unlimited data, it's best to reach out to your service provider's customer support. They will be able to assist you further and troubleshoot the issue.
3. Update or reinstall the GigaLife App: If the message you received mentions the GigaLife App, make sure that you have the latest version installed on your device. If you already have the app, try uninstalling and reinstalling it to see if that resolves the issue.
4. Check for any fair usage policy: Some unlimited data plans may have fair usage policies, which means that after a certain amount of data usage, your speed may be reduced. Contact your service provider to inquire about any such policies that may be affecting your data usage.
Remember that it's always best to directly contact your service provider's customer support for accurate and personalized assistance.
