Microsoft and Opera Software, on Wednesday signed the agreement to extend the Opera Mobile Store to more Nokia phones. Now, Opera Mobile Store will replace Nokia Store as the default app store for Nokia feature phones, Symbian and Nokia X smartphone.

Beginning in the first quarter of 2015, people who access Nokia Store from Series 40, Series 60, Symbian, Asha and Nokia X devices will be automatically redirected to Opera Mobile Store, where they will be offered the opportunity to become customers of Opera Mobile Store and have access to tens of thousands of apps for their Nokia phones.

“We continue to sell and support classic Nokia devices, which remain popular in many parts of the world. We’re delighted to partner with Opera Software and continue to provide a reliable app store experience for consumers and developers alike,” said Rich Bernardo, Vice President, Phones, Microsoft.

“When the current users of the Nokia Store are migrated to Opera Mobile Store, they will continue to get fresh, interesting apps for their Nokia phones. The Opera Mobile Store becomes an even more significant player in the app store market, and Nokia mobile phone users get a first-class app store for years to come,” said Lars Boilesen, CEO of Opera Software.

The transition to Opera Mobile Store will enable millions of people who use classic Nokia phones to continue to have a trusted source for apps, games and content. The process of migrating customers from Nokia Store to Opera Mobile Store is expected to be complete in the first half of 2015, at which point Nokia Store will be closed.

When the transition of customers from the Nokia Store to the Opera Mobile Store is complete, Opera is positioned to become the third largest app store in terms of downloads.

With close to 300,000 apps and games available in the store today, and millions of downloads each day, the Opera Mobile Store has a wide reach for developers looking to distribute apps.

Opera Mobile Store today supports more than 7,500 different devices, from feature phones to the most advanced smartphones. It is a trusted platform used by more than 40,000 developers around the world.
