5G, the fifth generation of mobile networks, was first commercially deployed in December 2018 in South Korea, marking the world's inaugural 5G rollout. By April 2019, South Korea solidified its pioneer status with nationwide coverage, though Verizon in the US launched hours later, sparking rivalry more than the "first" claim.
Global expansion accelerated in 2019, with more than 50 operators launching services, including China, which surpassed 100 million subscribers by mid-2020. By 2023, 229 commercial networks existed worldwide, with growth driven by India, Brazil and African nations, where affordability initiatives lowered device costs. Despite the cost reduction, infrastructure costs and spectrum barriers remain.
The technology's evolution continues, with 5G Standalone networks expanding. China leads in infrastructure, covering 96% of towns with nearly 2 million base stations, while industrial applicationsāfrom offshore fishing to smart citiesādemonstrate 5G's transformative potential.
This week, Mobile Magazine highlights the top 10 telecom providers delivering 5G coverage around the worldālisted in no particular order.
