You haven’t specified exactly what you need such support and what business or target audience you want to cater to. Anyway, 5G services are still a rarity but available in around 40-50 countries and territories. It is still not widely available in the US, but the deployment is underway. Through an app that can cater to the features and lightning-fast speed of 5G, you also need a smartphone to support 5G services.
5G-enabled smartphones are also limited in the market and are expensive. But the latest
mobile app development means you are not far away from getting the most of 5G services in 1-2 years.
