Airbnb is partnering with T-Mobile parent Deutsche Telekom to preinstall its app in Android smartphones sold across 13 markets in Europe, including DT’s home market of Germany. Those who register for the service through DT will get €30 vouchers to stay in Airbnb rooms. While Airbnb has partnered with companies like business travel platform Concur to integrate its accommodation inventory, this is the first time Airbnb is working with a carrier to expand its business.
