NOS Reviews 

I am tempted to give NOS a second star because their prices are reasonable and the internet service itself has generally been fast and stable. But boy, is their customer service deficient. We have a holiday home in Portugal. A year ago, we went into their store and signed a new contract upgrading us to a faster broadband. Problem was, NOS failed to cancel the old contract and kept taking the direct debits for it. Telephone calls and store visits followed. We were promised it had been sorted, or we'd be getting a call back (never did), or we'd be transferred to someone who could help, but who then turned out not to speak English and put the phone down on us. Eventually had to go into the bank in Portugal and cancel the DD. But NOS are still sending us payment demands for the contract and threatening to cut us off if we don't pay. 4 store visits and 7 telephone calls and this still isn't sorted. What a colossal waste of time and effort, and unneeded stress, for something that should be straightforward and simple.

Absolutely impossible to cancel your contract when you are not in Portugal anymore. I have a contract with them because I did my Masters Degree in Lisbon and some of my friends moved into my flat after me so they continued using said contract. I am back in Germany now trying to cancel the contract but it is absolutely impossible. Several phone calls (if you are lucky enough to get someone on the phone that speaks english) and everyone telling me that I have to confirm the cancellation via SMS. That SMS never arrives. Then they give you a link to a cancellation form. To send said form you also have to confirm your account via SMS but in my account they list a telephone number that I never owned and of course I also somehow do not have the rights to change that phone number even though I am the only account admin.

Their customer care is extremely difficult to contact and the representatives are not willing to help at all.

Demasiado demorado. Cerca de 1 semana para terminarem uma instalação em condições.

tenho contacto com a verisure de alarmes desde Maio 2021. Fiz o contrato de alarme no dia 29 de maio de 2026 quando fui visitado pela nos em que me foi dito pelos funcionarios da NOS a propor o contracto de alarme deles dizendo que seria da mesma empresa, e que apenas teriam uma parceria com a securitas mas que a empresa de alarmes seria a mesma. indicaram tambem que nao iriam lançar uma fatura no primeiro mês (Junho) para nao duplicar a fatura do alarme antigo (emitiram na mesma) e fizeram uma declaração que a Nos ficou de enviar a verisure para cancelar o contracto antigo. Dado que o periodo experimental seria de um mês, deparei-me agora em julho com outra fatura duplicada e liguei a verisure onde me indicaram que as empresas de alarmes sao concorrentes e nao são a mesma empresa. A informação que me foi indicada foi falsa no acto de concordar com a instalação. Nunca tive intenção de trocar de empresa que presta o serviço, e o que me foi dito é mentira. A declaração de rescisão preenchida no dia de instalação apenas foi enviada agora a 02 de julho para a verisure, onde agora ja terminou o período experimental. irei cancelar o serviço uma vez que as condições que me foram apresentadas inicialmente são falsas. agora parta cancelar querem mais de 1000€

Já ando há dois dias a tentar entrar em contacto com apoio ao cliente da NOS já sou cliente há muitos anos e o serviço de apoio ao cliente está terrível dizem que estão sem sistema INFORMÁTICO COMO É QUE É POSSÍVEL UMA EMPRESA DESTAS DEIXAR CHEGAR A ESTE PONTO!

I am writing to formally report an incident that occurred on 17 June at approximately 3:30 PM on Rua das Gândaras, Seixezelo, Vila Nova de Gaia, which had a direct impact on public safety and service continuity.
A waste collection truck damaged the cabling installed on the building façade, pulling it down and leaving several cables exposed on the ground. This caused a service interruption in the area and created an evident risk to both people and property.
Given the seriousness of the situation, I urgently requested without sucess:

The formal registration of this incident;
Written confirmation of the cause of the fault and the respective liabilities;
The immediate removal of loose cables and the cleaning of the public roadway;
The implementation of measures to ensure the safety of the area;
The permanent and proper restoration of the affected infrastructure.

Additionally, it is important to note that the intervention carried out by the NOS team to restore the service did not meet the minimum standards of quality and safety expected. I therefore also requested that this work be properly inspected and corrected.
I further inform you that there is material damage associated with this incident and that a report has already been filed with the competent authorities.

I am not surprised at the terrible reviews of NOS. They are basically thieves. We cancelled our contract on the 18th May 2026 yet they took two more standing orders from our bank account. Basically, we will have to go into our bank to stop them taking payments. I have heard the same from other former customers. They will not refund the money and refuse to connect you to the accounts department. Thieves. 🤬

Interrupções constantes dos serviços.
Comerciais a ligar para fazer novos contratos, temos sempre.
Mas também temos avarias constantes, que demoram dias a serem resolvidas e nos fazem perder imenso dinheiro...mas ninguém na Nós está preocupado.
Qual fibra mais rápida..só que funcionasse para que pudéssemos trabalhar..

4 weeks with fibre not working, no contact or reasons.. and tied in for 2 years!!

We are filing to cancel and change providers..

Such a shame, we were happy until we just got disconnected and forgotten about!

Subject: Formal Complaint - Billing Dispute and Warning - Account
​To whom it may concern,
​I am writing to formally contest the unjustified increase in my monthly bill. I hereby confirm that my bill for the previous month was paid in full, as has been the case for every single month prior.
​It is completely unacceptable that you are claiming amounts that have already been settled and doubling my tariff without any prior notification or contractual justification.
​Please consider this message a formal warning: if this situation is not rectified immediately, I will have no choice but to expose this dispute publicly on social media and report these practices to the relevant regulatory authorities (specifically through the Livro de Reclamações and ANACOM).
​I demand an immediate correction of my account balances and a written confirmation that this issue has been resolved.
​I expect your response within 48 hours.
​Sincerely,
​[Cherrier roland ]

Ils sont venus faire une installation chez moi , l'installation des porc

It’s not the fastest, and not the cheapest. It works kind of minimum acceptable with occasional downtimes in f internet acess. Beware as if there’s a bigger issue you may go 2 to 3 days without internet. And this is in the center of Lisboa, Avenida Liberdade…. Imagine outside the center of the capital

A fuir !!!! personnel très désagréable et obstiné, service client formé à faire du forcing. Accrochez vous bien si vous voulez résilier et surtout avant la fin de " fédilisaçāo" même avec un motif légitime,cas de retour à l'étranger, ils forcent les clients de rester quitte à les menacer de prélever le montant restant de la fédilisaçāo.
Personnel très ancré sur ce qu'ils ont compris de la part de leur supériorité, et supériorité inflexible qui ne souhaite pas évoluer sur un monde plus ouvert et constructif. Système qui tourne surtout autour de l'argent et qui souhaite surtout écraser le peuple.

Worst experience ever
If you are not portuguese - NEVER AT ANY COST SIGN A CONTRACT WITH THEM.
No proper support, no way to easily cancel the contract, no easy way to eve nrenew it.
It's a trash dump not a service provider

so bad it has made me depressed
Truly dog shit stuff mate
Somehow it gets worse every day XD?

Estou há três dias consecutivos sem serviço de internet da NOS e a experiência tem sido absolutamente inaceitável.
Desde o início da avaria, já realizámos mais de dez contactos com o apoio ao cliente. Em cada chamada recebemos informações contraditórias: primeiro disseram-nos que se tratava de uma avaria geral com resolução prevista “em breve”; depois foram sucessivamente adiando prazos que nunca se concretizaram.
O mais grave é que, ao longo destes dias, tenho recebido repetidamente SMS automáticos da NOS a informar que o serviço já tinha sido restabelecido e a pedir que reiniciasse os equipamentos. Cada vez que recebia essas mensagens, voltava para casa com esperança de conseguir finalmente trabalhar normalmente — apenas para descobrir que continuava sem qualquer acesso à internet.
No último contacto telefónico, fui finalmente informada por uma colaboradora de que:
1. a avaria ainda nem sequer tinha sido identificada;
2. não existe previsão real de resolução;
3. e os SMS enviados automaticamente pelo sistema não correspondem ao estado real da situação.
Ou seja: durante dias fui induzida em erro por comunicações automáticas falsas, enquanto o problema nem sequer estava a ser efetivamente tratado.
Esta situação causou-me prejuízos profissionais e financeiros concretos. Trabalho parcialmente a partir de casa e fui obrigada a deslocar-me diariamente para outros locais com internet, acumulando despesas de transporte (Uber) que já ultrapassam o valor da mensalidade do serviço.
Considero inaceitável:
a interrupção prolongada de um serviço essencial;
a falta de transparência;
a ausência de informação fiável;
e o envio automático de mensagens incorretas que apenas aumentam o transtorno dos clientes.
Exijo:
- o ressarcimento do período sem serviço;
- uma compensação pelos prejuízos causados;
- e uma resposta clara e séria por parte da NOS.
Neste momento, pondero seriamente cancelar o contrato, dada a total falta de confiança na forma como esta situação foi gerida.

DON'T USE NOS nor MEO!!!!!
I went to NOS for two phone lines.
1. I wanted a month to month contract and not a 24 months contract. DISREGARDED!
2. After my ex partner went back to Canada, I tried to cancel THAT number. NO GO BECAUSE APPARENTLY I SIGNED A TWO YEARS CONTRACT!!!
3. On the phone to dispute for hours! Finally got a message about some resolution. What exactly? I don't know!
4. Went to Canada to help my wife with her Visa. Was there for ten months. Couldn't cancel, even that I have a recorded statement that, if I went back to Canada, they would cancel the contract.
5. Was told to file a complaint with NOS. Couldn't find the shortcut online on their English website. Finally found it on the Portuguese website. Discrimination against English speakers?!!!
6. One day before I came back to Portugal, I got the message that my contract was canceled and litigation threat.
7. Was able to file a complaint with Livro de reclamacao after I found the shortcut on their Portuguese website.
8. Some of the customer service support people are nice, others rather rude. Most of them are helpful
9. Staff at stores are not reliable as they OBVIOUSLY don't listen or maybe prey on the inability of newcomers to understand Portuguese. That's just my guess! However, I got screwed over twice, as I tried to update the contract, they put that as a new start date of a new 24 month period contract without my consent or understanding. Total scam!
10. AVOID AT ANY COST AND RATHER GO TO VODAFONE! Choose PREPAID ONLY! Yes, a bit more expensive, but no binding contract!

Those guys are mental or something. I tried calling the support once to get more details before using their services. The support didn’t answer. But now, when I already moved on with another provider, they call me 10 times per day and I can’t stop it. When I ask them to speak English they just hang up. And then call and speak Portuguese again….
