Vodafone Group, the world’s largest mobile company, on Tuesday said it made an offer of roughly $30 million for Swedish GPS application developer Wayfinder.

The offer of $1.47 per share represents a premium of 253 percent compared to Wayfinder’s closing price on Monday of $0.42 per share. The deal is expected to go through without a hitch.

“This is not a surprise. Navigation is the killer app for mobile right now because you can put so many other things on top of it. You start with maps and then you put restaurants and then connect it to a reservation or transaction engine,” said Shahid Khan, an analyst with IBB Consulting.

The deal comes one day after Vodafone announced it signed a deal with Western Union to pilot an application that allows residents of Reading in the U.K. to send money via mobile phones to relatives and friends in Kenya.

Money transfers are already popular in Kenya where a service marketed by Safaricom, a carrier part-owned by Vodafone, has already attracted 4 million customers transferring money within Kenya. (Vodafone Wants $2.5B Stake in Vodacom)

As revenues from voice and data continue to fall, carriers are looking for alternate sources of income and revenues based on applications such as navigation or money transfers along with advertising have become quite attractive.

Stockholm-based Wayfinder offers a number of navigation apps including a turn-by-turn system, along with an application that tracks outdoor activities and another that manages speed-checking cameras.

The company‘s maps cover about 150 countries and it currently has 2 million users.
