Programmable Wireless SIMs May Experience Connectivity Issues With SK Telekom In South Korea

Incident Report for Twilio

Resolved

Connectivity issues with Programmable Wireless in South Korea have been resolved. Our connectivity partner for Programmable Wireless steered the traffic away from SK Telecom and LGU to Korea Telecom. Devices using Programmable Wireless SIMs are expected to only use Korea Telecom (KT). In case your devices haven’t moved to KT, rebooting the devices or sending a connectivity reset will cause them to switch over to KT. Please see https://support.twilio.com/hc/en-us/articles/360020619893-Resetting-a-Wireless-SIM-s-Network-Connection for more information.

Please be advised, roaming options in South Korea have changed and SK Telecom is not a network option open to Programmable Wireless.
