Roamer has raised $1.3 million (£770,000) seed investment for its mobile app that "eliminates mobile roaming charges" for users around the world.
The funding has come from investors including Richard Frank, the founder of Dial-a-Phone. Roamer’s technology is available in most countries and enables users to link their regular mobile number to a local SIM card via the Roamer app.
This provides for "an easy and comprehensive roaming experience", said Roamer, including low-cost calls and locally priced data. Customers can also use Roamer via WiFi in order to make calls from their own number, without the need to swap their SIM card.
Such methods are potentially more convenient than traditional services that have been popular among travellers, such as voice over IP (VoIP), because they do not rely on the person back home having to subscribe to or download a specific service. The person at the other end of the call simply answers or calls back in the usual way.
Roamer co-founder Simon Rabin said, "The new investment round, including funding from industry veteran Richard Frank, will help us to widen our unique service and bring it to a mainstream audience.
"Our beta customers have already reaped the benefits of Roamer while on their travels. With the proliferation of mobile use in everyday life, there is really no excuse in hitting consumers with excessive roaming charges anymore."
Despite recent changes in European legislation which seek to regulate roaming charges, consumers are still footing unnecessarily high mobile phone bills. Outside of the EU, less regulation and industry collaboration exists and operators are able to impose higher surcharges on customers.
Roamer says users benefit from savings of up to 97 percent on international roaming charges.
Roamer is free to download and is available from the App Store and GooglePlay, with users simply topping-up their account on a pay-as-you-go basis.
The exact cost of each local call is transparent and made easily available to the customer in real-time. There is no need to navigate complicated mobile roaming price plans or purchase add-ons, said Roamer.
Accessing voicemail via the app is free - users can record a personalised greeting and Roamer emails each message to the user directly as an MP3 file.
