Here's another tutorial on how to get GPT for free using Indonesian GoPay: Preparation work and account registration Prepare an email address: Register an email address (it is recommended to use a newly registered "account" specifically for handling this matter). Download apps: Download WhatsApp and GoPay (Indonesian electronic wallets) through the Google Play Store or other external app markets, and complete registration and login using your domestic+86 phone number. Register GPT account: Switch the network proxy (ladder) to the Japanese node, and then use the 163 email address registered in the first step to register a brand new ChatGPT account. Obtain trial and payment configurations Find the trial entrance: After logging into GPT, click on "Upgrade Plus" at the top of the page, or check for any discount tips in the bottom left corner. The goal is to find the option for "0 yuan trial". Switch country/region: In the bottom right corner of the subscription page, manually switch the region to Indonesia. Fill in the billing address: * Choose GoPay as the payment method. Use the online 'Singapore Address Generator' to generate a virtual Singapore address and fill it in on the billing page. Set up payment PIN code: Open the GoPay app on your phone, click on the profile in the bottom right corner, find the setting item containing the pin keyword, enter and confirm the payment password twice. Verification and anti deduction fees Mobile phone number verification: Go back to the GPT subscription page on the web page, click subscribe, select+86 (China) where you are required to enter your mobile phone number, and fill in your domestic mobile phone number. WhatsApp QR code: The verification code will not be sent via regular SMS, but will be sent to the WhatsApp you just registered on. Enter the verification code to complete the subscription. Cancel automatic renewal: To prevent automatic deduction after the free trial period ends, you need to immediately return to the lower left corner of the GPT page: click Settings ->Account ->Management, and cancel the subscription.
