The very small number of people who are capable and inclined can now roam between the 5G networks of Swisscom and either SK Telecom or Elisa.

Swisscom has over 6 million mobile subscribers but hasn’t revealed how many of them have upgraded to 5G. Since Swisscom only started to roll out its 5G network in April of this year, it seems safe to assume its 5G subscriber base is struggling to hit six figures. Of those, owners of Samsung Galaxy S10 5G smartphones can now fly from Zurich to Seoul confident of maintaining their newly-won boosted download speeds. The converse is true of SK Telecom’s 5G punters.

“SK Telecom once again proved its leadership in advanced roaming technology with the launch of world’s first 5G roaming service” said Han Myung-jin, Head of the MNO Business Supporting Group of SK Telecom. “We will continuously expand our 5G roaming service to enhance customer experience and benefits.”

“We want to offer our customers the best network – both in Switzerland and abroad,” said Dirk Wierzbitzki, Head of Product and Marketing at Swisscom. “So we are proud to be one of the world’s first providers to offer 5G abroad. We will continue to expand 5G availability abroad with additional partners.”

Swisscom has struck up a similar deal with Finnish operator Elisa, which is also claiming the world first, so it looks like SK Telecom has a fight on its hands. We were amongst the first countries to start building 5G networks in Finland,” said Elisa’s Director of Consumer Handset Subscriptions Jan Virkki. “Now that Swisscom has opened their 5G network, we are more than happy to be able to provide the ultrafast 5G to our consumer and corporate customers travelling to Switzerland.”

Roaming specialist BICS also wants a piece of the action, having got involved in the SK Telecom gig. “Today’s successful implementation of a trans-continental 5G data roaming relation further endorses our position at the forefront of global mobility for people, applications and things,” crowed Mikaël Schachne, CMO and VP Mobility & IoT Business at BICS. We couldn’t find any other corporate chest-beating over this bit of news but there probably was some.
