In order to remove an operator from the Blacklist and being able to reconnect to it, you can easily follow below steps :
From EUI Dashboard
- Click "Endpoints" tab
- Select the ICCID/Endpoint
- Click on "Operator Blacklist"
- Click on the red cross beside each operator you want to remove.
Once removed, do not forget to do reset connectivity on the endpoint for the changes to take effect.
You can follow the same steps if you have several operators you want to remove from the blacklist.
