Change in SMS senders of AOC services

Until recently, the SMS sent from the AOC services did not have information about the name of the sender, but rather a phone number:

And now, to make it easier to identify where the message came from, AOC services that send SMS report the following sender name: 

Service Sender 
Beast S. Social 
idCAT Mobile (subscribe to the service) idCATMobil 
e-NOTUM AOC 
e-TRAM AOC
