After dealing with countless signup issues, payment verification problems, anti-fraud blocks, billing confusion, and AI service limitations, I decided to write everything I know in one place.
Save this post. What you are reading is the result of two years of hands-on experience helping hundreds of small and medium-sized businesses activate Google Cloud Free Trial accounts and start using AI solutions in their companies.
1. What Is Google Cloud Free Trial?
Google Cloud offers new users:
- $300 USD in free credits
- Valid for 90 days
- No automatic charges during the trial period
When you sign up, Google requires:
- Personal information
- Tax information depending on your country
- A payment method
The payment verification process is handled by Google’s anti-fraud systems, and sometimes legitimate users are blocked because their account does not look trustworthy enough.
2. What Can You Use the $300 Credits For?
The credits can be used for many Google Cloud services:
- Compute Engine (VMs): Yes
- Cloud Storage: Yes
- Cloud Run: Yes
- Cloud Functions: Yes
- Kubernetes Engine (GKE): Yes
- Cloud SQL: Yes
- BigQuery: Yes
- Vertex AI / Gemini Agent Platform: Yes
Google AI Studio API: No
Be extremely careful with this. Many people believe they are testing Gemini using their $300 credits, but they are actually consuming another billing method.
Before using any resource, always verify if it is eligible for Free Trial credits.

IMPORTANT: Your Google Cloud Free Trial credits can be used for Gemini AI, but only through Google Cloud’s AI platform (formerly Vertex AI, now part of the Agent Platform ecosystem). They cannot be used for Google AI Studio.
3. Payment Verification Problems
Most signup failures are not technical errors. They are Google’s anti-fraud system refusing to trust the account.
The two errors I have seen the most are:
- OR_BACR2_44 — Payment Method / Account Trust Issue
This error usually means Google does not trust the combination of your account, network, location, and payment method.
Common causes:
- Virtual cards
- VPN or proxy
- Mobile network IP
- New Google account
- Browser privacy tools
What usually helps
- Use a physical credit card
- Use a traditional bank card
- Make sure your card name matches your account
- Use your home WiFi
- Disable VPN/proxy
There is no guaranteed fix. The goal is to make your account look as legitimate as possible.
- OR_BACR2_59 — Higher Risk Anti-Fraud Block
This is a more complicated issue.
It often happens when Google flags:
- Your IP address
- Your personal information
- Your account history
Some solutions that worked:
- Different Google account
- Different IP address
- Different network
4. The Prepayment Requirement
Some accounts are required to make a prepayment before receiving the free credits.
The amount varies by country and risk evaluation.
Typical range: $10-$50 USD
This payment is refundable.
5. How Prepayment Works
The prepayment creates a billing balance, and this is where many users get confused.
The prepayment is not completely separate from your Google Cloud usage.
Example:
You receive: $300 Free Trial credits and you make: $20 prepayment
If you use only eligible services, your Free Trial credits are consumed first.
However, if you use a service that is NOT eligible for Free Trial credits, Google can consume the prepaid balance.
Always verify if a service is eligible before using it. Check eligible services:

6. Requesting a Prepayment Refund
I want to be transparent here: I have not personally tested every refund scenario. This information comes from reports from users I helped and people sharing their experiences.
The refund can be requested using the dedicated refund button.

The refund approval email usually arrives quickly. However, the money can take a week or more to appear back on your card.
If it takes longer than two weeks, contact Google Cloud support and specifically ask to speak with a human agent. Automated support often cannot solve billing cases.
One thing that is still unclear:
Some users reported that requesting the refund may remove their Free Trial credits.
I have not confirmed this personally.
7. The “Activate” button trap
This is one of the most important things new users need to understand.
During the Free Trial, Google may show a very visible button saying: “Activate”
Many people think this means activating their free credits. It does not!
This action converts your account into a full billing account, which allows Google to charge your payment method after the Free Trial period ends.
Your Free Trial credits and remaining trial period do not change:
- You still have the same $300 USD credits.
- You still have the same 90-day trial period.
- You do not lose your remaining credits.
The main difference is what happens after the trial ends.
With the Free Trial, Google does not automatically charge you after expiration.
With a full billing account, your services can continue running and Google can charge your payment method if you do not manually stop resources or disable billing.
One important benefit of activating the full account is that your quotas and service limits increase. The Free Trial account operates with more restrictive limits, and users working with AI services often hit those restrictions. After activating the full account, higher quotas become available.
But remember: If you forget to disable billing after the trial period, Google can charge your card. And a small mistake can become a huge bill. Be careful. Billing alerts only notify you. They do not stop spending.
PS: Do not panic if your billing page shows your Free Trial credits as expired after activating the full account. This does not mean you lost your credits. The credits are reactivated as credits from the full billing account, so they continue to be available.
