Movistar, Orange and Vodafone will all provide direct carrier billing technology to a mobile ticketing app in a deal engineered by DOCOMO Digital.
The e-Park app enables customers to buy tickets for parking spaces in 13 Spanish cities and gives them the chance to offer time left on meters to other users.
Customers of the country’s three largest operators can now pay for the service, which has been downloaded by over 500,000 Spaniards, via their mobile bill.
It is the second time that DOCOMO Digital, which provides the technology platform behind the carrier billing, has persuaded Movistar, Orange and Vodafone to work together.
The telcos also provide carrier billing to bus company Alsa, which told DOCOMO Digital it did not want to work with just one operator in 2015.
Announcing the e-Park deal, DOCOMO Digital cited research from Ovum forecasting a $180 billion revenue opportunity in carrier billing.
It said operators had a better chance of unlocking these revenues if they put aside their differences and worked together.
The company has also signed deals with Sunrise, Three Ireland and Vodafone UK, but Spain remains the only country where operators appear willing to work together.
Fernando González-Mesones, COO of DOCOMO Digital, said: “Our mission is to provide value both for companies and users to ensure more and more people, no matter what payment methods they use, are able to access the many advantages e-commerce and m-commerce brings.”
