Frequently asked questions
What does it cost to hold a Prex account?+
The monthly fee is UYU 0, and the account sits on a no monthly fee model. That makes it a cheap place to hold a prepaid card, and any other charges come from what you spend rather than from holding the account.
What kind of card is it?+
It is a prepaid card on the mastercard network. Because it is prepaid, the balance you top up is what you can spend, which suits users who want a set limit rather than an open account.
How fast is money available after a top-up?+
Funding is Credited to your Prex account instantly. There is no waiting period described, so a user can top up and use the balance in the same sitting.
Who runs the account and where?+
The legal entity is Econstar S.A., with headquarters in Uruguay. The licence listing names Banco Central del Uruguay as the regulator, so the account is supervised there rather than in the UK or Europe.
How do I get help?+
Support runs on email, chat and phone. That gives a choice of channels rather than a single route, though the account itself works from the Prex app, per 24/7 access from the Prex app, balance usable at any time.
Does it hold several currencies and crypto?+
The feature list includes multi-currency, crypto and travel. That suits users who want one prepaid card for spending abroad and digital assets rather than separate accounts per currency.
Is it aimed at adults or children?+
The audience covers kids and business users. Parents can set up spending for a child, and small business users can keep spend separate, which is why the prepaid format is a good fit for both.
Does Prex lend money as well?+
It is a direct lender offering personal lending. Borrowing is therefore personal rather than secured or business, so readers wanting an investment property loan would need a different provider.
