SIM Activation

Hello ​@PAUL311,

Thank you for your message. Could you please confirm whether your data plan is prepaid or postpaid? The activation process may differ depending on the type of service.

Once we have this information, we’ll be happy to guide you through the correct activation steps.

Kind regards

Hi. 
It's a post paid account.

I am going to use it in a 5G router.

I've tried putting the sim in a phone, but no success.

Regards 

Hello ​@PAUL311,

Thank you for your feedback. 

Since its a post paid, the card is already active as its delivered.

When you tried it in a smartphone, did it request a pin code? Did the card established a 4G connection? 

Thank you 

I have the same problem - new data only SIM, post paid.  I have put it in iPhone but does not work as no internet access.  I have a full NOS signal but it seems card it not activated.  Do I need to activate it somehow?  Thank you.

Good afternoon ​@Rebecca Hunt,

We’re happy to help. For data-only SIM cards, manual activation by the customer is not required. Have you tried the mobile data SIM card in another device?

Thank you

Thanks for your quick reply, I have tried the SIM in a wifi router, plus an iphone XR and iphone 14 - both show the following message:-

“Could not activate mobile data network

PDP authentication failure”

Hope you can help!, thanks ☺️ 

Good afternoon, ​@Rebecca Hunt 

Thank you for the details; this information is very helpful.😊

The message “PDP authentication failure” indicates that the SIM card is unable to authenticate the data connection on the network, which is usually related to the APN settings or the service activation status.

Given that you’ve already tested it on several devices, everything points to the issue being related to the SIM card or service.

Please send us a private message to the ​@Fórum profile with your mobile internet SIM card number so we can verify that the service is properly active and help you resolve this as quickly as possible.

Thank you

A few days ago, I purchased a SIM card from NOS company. After inserting it into my phone, it showed no service and there were no signal indicators.

Hello ​@Fabio marques cunha, welcome to the NOS Forum.

We appreciate your message and are here to help you.

To do so, please give us with more details about the situation.

What type of SIM card did you purchase and which tariff plan is associated with it?

Thank you

This card, I am a Chinese tourist, I don't know how to contact you, so I can only try on the forum. I don't know what to do now.

Hello ​@Fabio marques cunha,

Can you please tell us how much you paid for the SIM card, or whether you have already made any top-ups?

Thank you

I can provide my phone number, as well as the SIM card PIN and PUK codes. Could you please check in the backend or on the terminalCan you help me activate it?

Hello ​@Fabio marques cunha,

We have removed the images you shared as they contained personal data. For your protection, we recommend that you do not share personal information publicly.

Please test the SIM cards in another device and let us know whether the issue persists or if it has been resolved.

Thank you

I have tried several devices, but I still cannot use it.

Thank you for your feedback, ​@Fabio marques cunha.

Based on the information available, we recommend visiting the store where you purchased the SIM cards so that the team can verify what happened.

Once you've visited the store, please let us know the outcome. We'll be happy to help you.

I am currently in Belgium and cannot reach Portugal.

Hello ​@Fabio marques cunha,

As the SIM cards were purchased in Portugal, they must first be activated on the Portuguese NOS network before they can be used while roaming abroad.

As you are currently in Belgium, we kindly ask you to manually search for available mobile networks with the SIM card inserted in your device. This will allow us to check whether the SIM card is able to register on a network and activate the service.

If the SIM cards were never connected to the NOS network in Portugal, they may not have been activated correctly, which would explain why they are not working in Belgium.

Thank you
