Good day @Vanreet,

You plan is for hotspots or mobile?

If it is for mobile try connecting manually to these operators.

Good luck

I tried to connecting with these operators but it says forbidden. Is there any other way ?

It's a mobile data plan

There are several experiences sharing the same issue.

I advice you to send a private message to @Fórum  with you customer number.

Thank you

Where did you read that the tariff has Unlimited Internet in Europe?

Hello @Vanreet,

I asked if it was hotspot (device) or mobile data plan (mobile phone).

Please provide more details about your plan.

Thank you

So the NOS store in OPorto sold me an incorrect SIM card to use outside of Portugal even though I requested 1 to take me throughout EU

We are sorry for the situation but @DanielS was a good help, @Marshall Semeniuk 
The mobile internet tariff does not provide for internet traffic in Roaming, only mobile tariffs allow it. 

Best Regards,
