I do not receive verification SMS

Have you tried putting the card on another phone?

Hello ​@Marcelo2503, welcome to the NOS Forum.

We appreciate yor message. ​@Guimas  made a good recommendation.
Please confirm whether the same happens when testing the SIM card in another device.

Thank you,

Yes the same happens on another phone.

The SMSs are coming probably from a number that is not Portuguese (Germany and other)

Hello ​@Marcelo2503,

Thank you for the feedback.
Please tell us if you are using your NOS number in Portugal.

Yes, it's NOS number and I am in Portugal

Hello ​@Marcelo2503,

We appreciate the information. Is the SIM card you have new or a replacement (duplicate) card?
Please confirm whether you recently ported an existing number to NOS.

Thank you,

No it's the same number just a new phone.

And I didn't receive the SMS on the old phone either.

Just via another provider.

Hello ​@Marcelo2503,

We’ll help analyze it. Please send us a private message on profile ​@Fórum including the number in question and the associated NIF.

Thank you
