The configuration changes made by Tele2 are successful. 25% of Tele2 SIM cards are now back in operation including all the Estonian SIM cards (which are used for roaming in Sweden).

Tele2 has now started to un-block the rest of the SIM cards which is expected to take 1-2 hours to complete.

Tunstall will be among the prioritized customers to be un-blocked.

Removing routing to bypass suspected nodes seems to have stabilized the failure rate for our subscribers.

Troubleshooting is ongoing and the issue is still affecting data and voice communication network sessions over 2G, 3G and 4G networks.

The supplier, Tele2, is working with its vendors to resolve the issue. They currently suspect a node routing issue which are currently bypassing which will restore service to their subscribers.
