UnionPay and Visa cards cannot currently be used — they cannot be loaded, paid for, renewed or newly issued, and existing cards are declined in shops, online and at ATMs. Your account, deposits, withdrawals and trading are not affected.

Official migration notice

Migrating from BOS?

Ultimox is the renewed platform operated by the same company as BOS, under the same ownership.

BOS accounts are being upgraded to Ultimox in stages, and existing BOS customers keep their account data and balances.

Start from your BOS dashboard → Official announcement: bos.ultimopay.io/ultimox-migration

How the migration works.

1

Sign in to BOS

Sign in to your existing account at bos.ultimopay.io.

2

Follow the guided steps

When the migration option appears in your dashboard, follow the guided steps described on the official announcement page.

3

Continue on Ultimox

Your account is activated here on app.ultimox.io, where you continue with the same balances and card.

The migration is rolled out in stages. If the option is not visible in your BOS dashboard yet, no action is required from you — it will appear when your account is included.

Important

You do not need to sign up for a new account on Ultimox. If you already have a BOS account, always start the migration from your BOS dashboard — never from an email link or a third-party site.

Questions or verification

You can verify this migration or get help through the support channel you already use — raise a ticket after signing in at bos.ultimopay.io — or email support@ultimox.io.
