Opera’s “Mini” browser will soon become the default web browser for Microsoft’s existing feature phones and Asha phones portfolio, says the mobile web browser.

According to the license issued, the agreement applies to mobile phones based on the Series 30+, Series 40 and Asha software platforms. Nokia’s own Xpress browser offered data compression services similar to those offered by Opera Mini.

So this means that every Nokia user who uses the Xpress browser should move to the latest Opera Mini browser. New devices will come with Opera Mini pre-installed.

“We continue to sell and support classic first and feature phones as well as the Asha range, which have performed well with millions of people who want new mobile experiences at lower price points,” said Rich Bernardo, head of legacy business, Phones, Microsoft.

“The agreement with Opera will enable us to provide continuity of service as we transition from Xpress Browser to Opera Mini.”
