Prerequisites
Google account (region matches your network; US region recommended).
US address (see US State Abbreviations Reference).
MPChat card with buffer for pre-auth (GCP billing setup often runs ~$1 verification).
Link card to GCP billing account
Go to Google Cloud Console → Billing → Add payment method.
Enter MPChat card details and billing address (match card page).
System may run ~$1 pre-auth (usually released later — not a real charge).
Once verified, billing is enabled.
⚠️ Ensure card balance covers pre-auth; release timingsee Special Notes on Cross-Border Unusual Billing.
Link card for AI Studio / Gemini API
Add MPChat card in billing/payment settings — similar to GCP.
Used for API usage billing — monitor usage and balance to avoid failed charges.
Symptom | What to do |
Pre-auth failed | Insufficient balance — top up and retry |
Free trial won't start | Virtual cards rarely pass free trials — plan for normal billing |
Address/region rejected | Align account region, IP, and billing address |
Repeated rejections | Don't rapid-retry; switch to clean IP; try later |
Usage charge failed | Keep sufficient balance incl. fee buffer |
Notes
GCP is pay-as-you-go — set budgets and alerts to avoid surprise large charges.
