To increase your GCash wallet limit, you'll need to verify your account by providing necessary identification and personal information. You can do this by completing the Know Your Customer (KYC) process through the app. Once your account is verified, your limits will automatically increase. Be sure to check the GCash app for any specific requirements and guidelines, or visit their official website for more detailed instructions. If you're uncertain, contacting GCash customer support can also help clarify the process.
