Official mobile certifications in various markets leak useful information about the upcoming phones. Now, three previously unknown Nokia phone variants TA-1075, TA-1105 & TA-1116 have appeared in Russian certifications.
As you can see in the screenshot below these three Nokia phone variants have passed certifications very recently in Russia.
It is obviously not clear which Nokia phone/smartphone these variants belong to. One thing is sure though with these variants appearing in certifications, HMD may be planning to launch new Nokia phones/smartphones in near future.
HMD is planning to launch Nokia X6 in China and may follow it with release of Nokia 5 2018, Nokia 3 2018 and Nokia 2 2018 and other smartphones.
