It passed more than a year since the first post and more than 50 messages exchanged with Fido support team explaining againg and again what is the problem. I got tired starting over with each support team member so I made a video - https://1drv.ms/v/s!AoabbSEVezB0mnP6Jq6RvQBfENlx of the issue.
After all that here is the official response from them:
"The first 2 options in your screenshot are Data Passes and when you don't have any data, you are redirected to the purchase page and asked to choose a Data Pass, therefore those 2 options can be added through there.
However, Data Add Ons (the $10/100 MB option), can only be added through the automated service when calling 611 or by speaking to customer service, therefore it will not work to add it through the Data Passes link."
I asked them to remove the 3rd option or at least put a proper message explaining what must be done but I don't expect to see it fixed any time soon.
Hey @plamenh
Thanks a lot for getting back to us on this 
Just to confirm a few things:
- You need to pay both Monthly Service Fee on voice plan and on data add-on to be able to access the data service.
- Your account balance has to be higher than the Monthly Service Fee on the date it’s charged.
We'll have to take a closer look at the details. You can reach out here or we can send you a PM.
Let us know what suits you best
Hey @plamenh,
I assure you that we're already looking into this and doing everything can we can to get it sorted out as fast as possible.
We'll update the thread once we have more details.
Hey @plamenh,
You're still having the same complications with the 3rd link?
Are you able to use the first two? Can you also confirm if you're on WiFi when you try clicking on the link?
What happens exactly when you select the 3rd option? Do you get an error message?
Hi @plamenh!
Valeska here taking over
We would need to look into that together.
I'm sending a PM your way in the next few minutes.
Talk to you there!
Hey @Jasadd!
Welcome to the Community
I will be happy to look into this with you.
Just to confirm, was your WiFi off when you tried to follow the link?
Also, does your balance cover the cost of the add-on?
That's definitely odd. I will be happy to take a look at your account and see if we can find anything there.
I'll be sending you a PM in the next couple of minutes. Talk to you soon
No word as of now. If you want the data option, I can reach to you in PM and add it on.
Let me know if you'd like to go down that route
Send us a private message when you get the chance and we'll sort it out for you @Dungleaddress
