Problems activating new SIM card

[jnscoelho]

I ordered a new SIM card from Sky about a week ago. Got it in the mail on 7th August and I've been trying to activate it since, without success.
I've tried 3 different devices (computers and phone) and 3 different browsers (Chrome, Edge, Firefox), cleaning cookies and history, nothing works.
Every time I click on "Activate SIM" on the Mobile product settings page, I'm redirected to a page where I get an error message saying 

It would be nice to be able to use the service that I've ordered...

To get you some help with this error message have escalated your post to the Sky Messaging team who should be in touch with you regarding this via a blue/red chat bubble which will appear at the bottom of this page. It can take up to a few hours to be contacted via this.

When the chat bubble does appear you will need to respond to it as soon as you can or it will be closed if there is no response within 48 hours. To start the conversation just type in it.
This isn't a live chat so replies may not be instant.
