In a statement, the company said it had a role in all 5G early adopter trials, with agreements with the top four American CSPs and the top three in Japan and South Korea.
It said, this week it had signed a new 5G deal with BT and a renewed deal with Elisa in Finland.
"Nokia's 5G portfolio is also gaining traction amongst enterprises," the company said.
It said the increasing momentum among CSPs and enterprises was being driven by advances in its technology.
"In February, Nokia revealed it was first in the world to pioneer 4G and 5G network slicing, which enables operators to deliver unique, isolated 'slices' of the end-to-end network to their customers, tailored to specific applications," the company said.
"In April, Nokia introduced the industry's first Dynamic Spectrum Sharing solution that supports spectrum sharing between 2G, 3G, 4G and 5G.
"In July, the company announced it can migrate five million legacy 4G radio units to 5G via a software upgrade, making it easier for operators to move to 5G.
"Nokia made its 5G standalone private wireless technology commercially available in July – the first network equipment provider to do so.
"And in August, Nokia contributed to the world's first large-scale 5G SA launch with T-Mobile in the US."
Nokia Mobile Networks president Tommi Uitto said: "We are thrilled to have passed this 5G milestone. We know we still have work to do and that the market remains highly competitive.
"But, we are moving fast – and these wins make it clear that our progress is being validated by customers. We deeply appreciate their ongoing support and are committed to delivering for them."
