Nothing on Blomo’s side stops it. A Blomo card is an ordinary online card number — the online-only Estonia card included — which a merchant can store and charge on a schedule, with nothing to re-enter each month. What Blomo cannot promise is that a given service will accept it: that decision belongs to the merchant, it is made from the card number before your balance is ever consulted, and the only way to find out is to attach the card and see. What Blomo does control is the balance, and that is where subscriptions on a card like this actually break. One Blomo action empties the spendable balance without any money leaving: ordering a new card holds your whole balance until that card is activated. A renewal that lands inside that window fails.
This article is about the mechanics of a recurring charge, because that is where the difference between a card funded from a balance and a card attached to a bank account actually shows up.
What a subscription does that a one-off payment does not
A single purchase is one authorisation and one settlement. A subscription is a sequence, and each step behaves differently.
The first charge is initiated by you, and it may not be the price you expect. Some merchants run a small verification charge and reverse it, some take the full first period, some do both at different moments. The amount that has to be available on day one is therefore not always the sticker price.
Every later charge is initiated by the merchant, not by you. The card details are stored on the merchant’s side and reused on a schedule. You are not present, there is no checkout page open, and nothing on your side gets a chance to intervene before the request is sent.
A failed renewal is usually not retried on the spot. Recurring billing systems commonly re-attempt a declined charge on a schedule of their own, and each service sets that schedule itself — Blomo neither sets it nor measures it, and cannot tell you what yours does. The part people misread is the consequence rather than the timing: the money was missing on the day of the charge, the retry arrives whenever that merchant retries, and by then the balance may look fine while the subscription is already marked past due.
Enough failures and the merchant ends the subscription. After how many attempts, and how long re-attaching the same card takes afterwards, is that merchant’s own rule. Some publish it in their billing help pages and some do not; Blomo has no view into it and does not guess on their behalf.
None of that is specific to Blomo. What is specific to Blomo is how easy it is to make the balance unavailable at exactly the wrong moment.
The Blomo-specific trap: ordering a card holds your whole balance
This is the part worth reading twice, and it is written into the code rather than into a policy page.
From the moment you order a card until that card is activated, the entire available balance you had at the moment of ordering is held and cannot be spent. Not the entry threshold — everything. The hold is a real double-entry posting to a separate hold account, which is why no charge can reach the money: after the hold, the spendable balance is what remains, and a subscription charge simply has nothing to draw on.
The consequences, in order:
- A recurring charge that arrives during the hold fails. The merchant sees a card that cannot pay, and starts its retry sequence.
- The hold is released when the card is activated, and also if an operator rejects the request. It is released in full and immediately; there is no deduction for a rejected request. There is no way to cancel a request yourself: the endpoint does not exist, so only activation or an operator ends the hold.
- If an issue attempt fails, the hold stays. A failed attempt is not a decision — the money remains held until an operator either retries the issue or declines the request.
- The hold is a snapshot of the balance at the moment you ordered. A top-up that arrives after you place the order is not held and stays spendable. That is the escape hatch: if a renewal falls inside the window, topping up after ordering gives the merchant something to charge.
- Only one card request can be open per account at a time.
The practical rule that follows: order a new card just after a renewal date, not just before it. If you cannot choose the timing, top up after placing the order and leave the renewal amount plus fee sitting on the spendable balance.
Blomo states the hold on its own product pages too — the minimum balance is checked once when you order, and the balance is held until the card is active (fees, virtual cards). It is repeated here because the cost of not knowing it is a cancelled subscription rather than an inconvenience.
How much headroom a renewal actually needs
The balance is denominated in USDT whatever the card currency is, and a card payment costs the amount plus the card’s transaction fee.
| Card | Currency | Transaction fee |
|---|---|---|
| Netherlands · Visa | EUR | 0.5% |
| Spain · Visa | EUR | 1% |
| Poland · Mastercard | PLN | 1% |
| United Kingdom · Visa | GBP | 1.5% |
| Indonesia · Mastercard | IDR | 1% |
| Estonia · Visa | EUR | 1% |
Rates from the Blomo fees page, which is the live source — read it there rather than trusting a number in an article.
Two more numbers shape the headroom you should keep:
- The minimum top-up is 50 USDT. Smaller deposits are not credited, so you cannot top a balance up by the exact three dollars a renewal is short.
- The top-up fee is 1% on top of the amount you ask to have credited. You name the sum you want on the balance, and you send that sum plus the fee: ask for 100 USDT and you transfer 101. The top-up screen shows the figure to send once you type the amount you want. What the merchant can charge is the credited amount, not the amount you transferred — how much to send so 500 USDT lands walks the arithmetic through.
Together those mean the smallest useful refill is larger than most monthly subscriptions, and that a balance kept exactly at the subscription price is a balance that will fail.
Currency: the amount debited is not the price on the label
A payment in the card’s own currency is not converted at all. Anything else is recalculated at the Visa or Mastercard rate for the moment of the transaction, and Blomo has no conversion rate of its own and adds no markup to the network’s rate.
For a subscription this has a specific consequence: a fixed monthly price in a currency other than your card’s currency arrives as a different USDT amount every month. A euro subscription on the Poland card, billed in zloty terms, moves with the rate. Keeping headroom rather than an exact figure is not caution here, it is arithmetic.
If the subscription is priced in EUR, PLN, GBP or IDR, there is a card in the range issued in that currency, and using it removes the conversion from the renewal entirely.
What “prepaid” actually means for a merchant
A Blomo card is funded from a balance you loaded in advance, which is what people mean by prepaid in ordinary speech. Whether each product’s number is registered as prepaid, debit or something else in the databases merchants consult is a separate question, and Blomo does not publish it.
That distinction matters here because a merchant that refuses prepaid ranges refuses subscriptions on them too, and it does so before any balance is consulted. If a service will not accept the card at sign-up, 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 does not promise that any specific service will accept a Blomo card for a subscription. Blomo’s own pages say recurring charges behave like any other online card payment, and that AI subscriptions bill the same way, but the acceptance rule belongs to the merchant. The only reliable test is to attach the card and see.
Card expiry ends a subscription too
Blomo cards are valid for 48 months, and 36 months on the Estonia card (fees). A subscription attached to a card outlives nothing: when the card expires, the stored details stop working, and the merchant treats it as a failed renewal like any other. If the card that runs your subscriptions is approaching the end of its term, replace the payment method before the term ends rather than after the first decline.
And note how this interacts with the hold: ordering the replacement card holds the balance on the old one. Order it in a gap between renewals, or top up after ordering.
Questions people actually ask
Can I use a Blomo card for Netflix, Spotify or cloud storage?
Nothing on Blomo’s side prevents it: the card number can be stored and charged on a schedule like any other online card, and Blomo states that subscriptions bill as ordinary online card payments. Whether a particular service accepts the card is that service’s decision, and Blomo does not promise it in advance. The only way to know is to attach the card.
What happens if the balance is empty when a subscription renews?
The charge fails. Recurring billing systems commonly retry on a schedule of their own rather than immediately, and enough failures end the subscription — but when, after how many attempts, and what happens if you re-attach the card is each merchant’s rule, not something Blomo sets or can see. Its billing help pages are where that answer lives.
Does ordering a new card affect my existing subscriptions?
Yes, and this is the important one. From the moment you order a card until it is activated, your whole available balance is held and cannot be spent, so a recurring charge arriving in that window will fail. The hold covers the balance as it stood when you ordered; a top-up made afterwards stays spendable.
When is the hold released?
On activation of the card, and also if an operator rejects the request — in full and immediately, with no deduction. You cannot cancel a request yourself. If an issue attempt fails, the hold stays in place until an operator retries the issue or declines the request.
How much should I keep on the balance for a subscription?
More than the price. The card’s transaction fee is added on top — 0.5% to 1.5% depending on the card — the minimum top-up is 50 USDT, the top-up fee is 1% added to whatever you ask to have credited (ask for 100, send 101), and a subscription priced in another currency arrives as a different USDT amount each month at the Visa or Mastercard rate.
Does Blomo charge anything extra for a recurring payment?
No. A recurring charge carries the same transaction fee as any other payment on that card, and Blomo adds no markup to the network’s conversion rate. The full table is on the fees page.
