Curve Curve Pay X
A plan byCurve · Mastercard
Curve is not an account: it is a card aggregator. A single Mastercard (physical or virtual) that forwards every purchase to one of your existing cards, chosen in the app, with the 'Go Back in Time' feature to move a transaction to another card after the fact. In the EEA it is issued by Curve Europe UAB, a Lithuanian electronic money institution supervised by the Bank of Lithuania. It does not custody your funds (it is a pass-through to the linked cards) and does not issue an IBAN. The base plan is free with 0% FX within a monthly allowance; at weekends, though, the free plan applies a 1.5% FX surcharge.

Strengths
- The only aggregator on the IT market: one Mastercard grouping all your other cards, with 'Go Back in Time' to move a purchase after the fact
- Free base plan, no annual fee, with 0% FX within the monthly allowance (EUR 250 on the free plan)
- Does not custody funds (pass-through to the linked cards) and works as an alternative wallet to Apple/Google Pay
- Self-custody: funds stay in your wallet — the platform cannot touch them.
Weaknesses
- At weekends the free plan applies a 1.5% FX surcharge (and beyond the monthly allowance)
- No IBAN and no account: it receives no salary or direct debits, it only adds a layer over your existing cards
- The best features (high FX allowances, broad cashback) are on paid plans (Pay X EUR 5.99 · Pro EUR 9.99 · Pro+ EUR 17.99/month)
- Full KYC required: verified identity, zero pseudonymity.
- Funds can be frozen at the platform’s discretion.
- Subject to regulation (Lithuanian EMI (Bank of Lithuania) · card aggregator, does not custody funds): reporting to authorities and freezes on order.
- FATF-aligned jurisdiction: strong cooperation with authorities.
- Closed source: no way to verify what it does with wallet and data.
Verdict
Curve is a unique idea on the Italian market — a Mastercard that aggregates all your cards, with the ability to move a purchase after the fact — and on the base plan it is free, no annual fee, with 0% FX within the monthly allowance. Hence the B rating. The limits holding the score back are concrete: the 1.5% weekend FX surcharge for those on the free plan, the absence of an IBAN and account (it does not replace a card or account, it layers over them) and the fact that the best perks sit behind a subscription. Useful as a convenience layer over your own cards, not as a primary tool.
Curve does not custody funds — the underlying cards hold the money — but it remains an EMI with full KYC: onboarding with identity, email and phone, every transaction tracked and the issuer able to suspend or close the account. It actually adds a further intermediary and further contracts between you and your spending. No permissionless use, no self-custody: on the sovereignty lens it is a convenience layer, not an autonomy one.

Needs context: the profile is claimed by the company under a paid subscription; Trustpilot flags that the company invites customers to review and has not replied to negative reviews. Distribution: 57% five-star, 24% one-star, 914 reviews in the last 12 months. The overall 2.3 therefore coexists with a historical majority of very good ratings.
Weighted average across 3 public review platforms (97,670 reviews in total), weighted by volume. This is not our rating: it is those platforms’ average.
Community signal
not verified by usPublic opinions collected from third parties, not verified by us. Online reviews can be manipulated: read them as a hint, not as data. The promp.it verdict remains the one above, based solely on official documents.
What users praise
- The product itself, one card aggregating all the others, is appreciated by long-time users
- Useful for paying with wearables where the underlying card is not supported
- When an agent actually picks up the case, resolution can be fast
What users criticise
- Cards and accounts blocked without notice or explanation, sometimes for weeks
- Very slow or absent support, automated replies and tickets with no follow-up
- Identity verification repeatedly failing with no explanation
- Frustration among premium subscribers left without a working card, including while travelling
The service’s own official accounts are excluded from the count. Read 16 Trustpilot reviews published between May and July 2026, plus the star distribution on the profile. Reddit and X were not accessible. Caveat: the Trustpilot profile is a paid one and the company solicits reviews, so the mix may be skewed in either direction.

Abysmal customer service. Blocked my card with no reason given and I cannot get through to the customer service team. Seems to be the same story in hundreds of other reviews.
-
Card blocked for two months, zero support. I've reached out about five times over two months: they say «someone will look into it», then nothing.
-
It was a bit fiddly to set up but works great.
