For Microsoft Azure and Amazon Web Services the honest answer is: do not try. Both say in their own documentation that they do not accept virtual cards, and every card Blomo issues without identity checks is virtual. Google Cloud is different: its billing documentation refuses prepaid cards and says nothing about virtual ones. Of the six Blomo cards, only the Estonia card is registered as prepaid, so Google’s prepaid rule excludes that one and not the other five. In Blomo’s own experience as of 27 September 2026, Google Cloud accepts Blomo cards; the Estonia card remains excluded by Google’s published prepaid rule. That is an observation, not a promise: Google can change how it treats a card range at any time.
What each provider says, word for word
All pages below were read on 26 September 2026. The dates in brackets are the “last updated” dates the pages show.
Microsoft Azure says it on three of its own documentation pages on learn.microsoft.com:
- “Prepaid and virtual cards are not accepted as payment for Azure subscriptions.” — Troubleshoot a declined card (8 March 2026).
- “Azure doesn’t support virtual or prepaid cards.” — Add, update, or delete a payment method (16 September 2026).
- “Virtual or prepaid credit cards aren’t accepted as payment for Azure subscriptions.” — Troubleshoot issues when you sign up for a new account in the Azure portal (5 February 2025).
The first page adds a second condition that matters on its own: “The name, address, and CVV code that you enter must match exactly what’s printed on the card.” On a Blomo card, the name is the one you enter in Latin letters when you order the card.
Amazon Web Services says it in its Knowledge Center article Learn the accepted payment methods for AWS, an AWS-written article on re:Post, which showed “Updated 5 months ago” when read:
- “Amazon.com gift cards, virtual credit cards (VCC), and PayPal aren’t accepted payment methods for AWS services.”
- “Prepaid credit and debit cards are accepted payment methods when they’re from the following card issuers.”
- “Note: It’s a best practice not to use prepaid cards. This is because if the prepaid balance runs out, then recurring payments might fail. Failed payments can result in the suspension of your AWS account.”
AWS accepts prepaid cards in principle, but not virtual ones. For the European seller, Amazon Web Services EMEA SARL, the same article lists “Credit and debit cards issued by Visa, MasterCard, or American Express”.
Google Cloud says it in its billing documentation, Add, remove, or update a payment method (24 September 2026), under “Unsupported payment methods”:
- “Prepaid cards aren’t accepted for payment.”
- “Debit cards that require two-factor authentication aren’t accepted for payment.”
The same page lists “Debit cards with the Visa or MasterCard logo” among accepted cards. Google’s console help has a one-line page, Prepaid cards cannot be used: “Prepaid cards cannot be used on Google Cloud Platform.” Neither page mentions virtual cards.
What that means card by card
Every Blomo card issued without KYC is a virtual card. How each card’s number is registered is a separate question: only the Estonia card is registered as prepaid, and the other five are not.
| Card | Virtual | Registered as prepaid | Azure’s rule | AWS’s rule | Google Cloud’s rules |
|---|---|---|---|---|---|
| Netherlands · Visa · EUR | Yes | No | Excluded | Excluded | Not excluded; accepted in Blomo’s experience |
| Spain · Visa · EUR | Yes | No | Excluded | Excluded | Not excluded; accepted in Blomo’s experience |
| Poland · Mastercard · PLN | Yes | No | Excluded | Excluded | Not excluded; accepted in Blomo’s experience |
| United Kingdom · Visa · GBP | Yes | No | Excluded | Excluded | Not excluded; accepted in Blomo’s experience |
| Indonesia · Mastercard · IDR | Yes | No | Excluded | Excluded | Not excluded; accepted in Blomo’s experience |
| Estonia · Visa · EUR | Yes | Yes | Excluded | Excluded | Excluded as prepaid |
“Excluded” means the provider’s own published rule names the card type. “Not excluded as prepaid” means Google’s prepaid rule does not catch the card — nothing more. “Accepted in Blomo’s experience” is Blomo’s observation as of 27 September 2026, not a rule Google publishes. The same Google page also refuses debit cards that require two-factor authentication; Blomo cards support 3-D Secure (the Blomo terms, section 11: “Every online charge requires your confirmation”), and in Blomo’s experience that rule has not stopped them. Google also checks the payment method when an account is opened — its Free Trial page says it uses payment information “To verify your identity” and “To reduce fraud” — and Blomo does not promise that Google Cloud, or any other merchant, will accept a particular card.
Why “do not try” and not “try and see”
A card that a provider’s terms exclude can still get through a sign-up form: nobody publishes how each check is done. That is precisely the problem.
A cloud account is not a one-off purchase. It holds running servers, databases and the data in them, and it is billed again every month. A payment method that breaks the provider’s rule can be refused at any renewal, not only at sign-up, and AWS itself spells out the consequence of failed payments: “suspension of your AWS account”. Putting a production system behind a card that the provider has said in writing it does not accept means betting that system on a check you cannot see.
So, for Azure and AWS: use a payment method they accept. Blomo is not one of them, and this article is not going to suggest a way around it.
If you use a Blomo card with Google Cloud
Google Cloud accepts the five non-prepaid Blomo cards in Blomo’s experience. Three things are worth knowing before you attach one.
- Google starts the charge, not you. Cloud usage is billed automatically, after the fact. A Blomo card pays from your Blomo balance, so the balance on the day of the charge decides whether the payment goes through. A new card order holds your whole available balance until that card is activated, which can make a renewal fail — ordering a second card explains the hold.
- The billing currency. Blomo cards are issued in EUR, PLN, GBP and IDR, not in dollars. A card in the same currency as your Google Cloud billing account keeps the bill in one currency: for a euro-billed account, that is the Netherlands or Spain card, since the Estonia card is outside Google’s prepaid rule.
- The card’s monthly limit. The Netherlands and Spain cards allow 100,000 USDT a month, Poland and the United Kingdom 50,000 USDT, Indonesia 30,000 USDT. The limit covers everything the card pays that month, not only cloud bills. Current figures are on the fees page.
If Google declines the card, the reason is usually the card number’s range rather than the money behind it. What a BIN is and why a shop declines your card covers that mechanism.
Blomo also issues plastic cards, and a plastic card requires KYC before it is made. This article is about the virtual cards, which do not.
Quick answers
Can I pay for Azure with a Blomo card? No. Microsoft’s documentation says “Prepaid and virtual cards are not accepted as payment for Azure subscriptions”, and every Blomo card issued without KYC is virtual.
Can I pay for AWS with a Blomo card? No. AWS says “virtual credit cards (VCC) … aren’t accepted payment methods for AWS services.”
Can I pay for Google Cloud with a Blomo card? Google refuses prepaid cards and says nothing about virtual ones. The Estonia card is registered as prepaid and is excluded. The other five are not caught by that rule, and in Blomo’s experience as of 27 September 2026 Google Cloud accepts them. That is an observation, not a guarantee: Google can change how it treats a card range.
Which Blomo card is prepaid? Only the Estonia card. The Netherlands, Spain, Poland, United Kingdom and Indonesia cards are not registered as prepaid.
What happens if a cloud payment fails? That is the provider’s rule. AWS says failed payments “can result in the suspension of your AWS account”.
