Digital banking platform Revolut said it was launching a streamlined version of its app in Sri Lanka, Chile, Ecuador, Azerbaijan and Oman, allowing customers to transfer money to over 50 countries using more than 30 currencies.
The London-based company said there would be no fee for customers transferring to other Revolut customers.
Transfers to non-Revolut accounts would incur a 1% fee, with a $1 minimum, in the five new countries.
Revolut, which has grown its range of products to include payments services, crypto trading, savings accounts and stock trading since launching in 2015, has said it wants to build a global financial "super app".
The platform, which has more than 18 million customers and 500,000 businesses using its products, said it aimed to be in up to 90 countries by the end of 2022.
It has almost 2 million customers in Ireland.
