We send you your bill or important information via e-mail or SMS. Convenient, isn't it? Nowadays, scammers also often send emails or SMS messages that are very similar to the ones yallo sends. The scammers try to get you to transfer money to them or provide personal information.

What is phishing?

The term phishing is derived from the English word "fishing". Phishing means obtaining confidential information, such as banking information, credit card numbers, account data and passwords.

Gaining access to this information allows criminals to withdraw money from your account, make purchases or shop online.

The fraudsters will falsify websites and e-mails from well-known companies and ask you to give them or confirm information such as your user name and password. The similarity to the authentic website is surprisingly high.

In order to recognize phishing attacks, caution and common sense are required.

In SMS phishing (smishing), text messages are sent with fraudulent links.

How do I detect phishing?

Spelling mistakes

If you receive a mail with many spelling mistakes, missing salutation or an unknown sender, you should stay alert. However, it is also possible that the phishing mail is error-free.

Unknown URL

Always check the URL before you enter your login details or other personal data on a website. Always make sure that you are on the correct website of the respective provider.


Phishing mails often ask you to act as quickly as possible. Time pressure can therefore be a sign of phishing.



✔️ Check if the sender's email address ends with @notifications.yallo.ch or @newsletters.yallo.ch or @digital.yallo.ch.
✔️ Check - before you click on it - if a link starts with https://yallo.ch.
✔️ Forward suspicious e-mail to abuse@sunrise.net
✔️ Immediately delete messages that you do not trust.
✔️ Have you found a phishing site? Report the phishing sites via web form.


❌ Never pay with bitcoins or vouchers. We will never ask you for them!
❌ Don't click on a link or button in a message you don't trust.
❌ Do "acquaintances" ask for money? If so, always call them to make sure it's him or her.
❌ Don't reply to messages you don't trust.

What to do if I became a victim of phishing?

Immediately change your login details for social networks, payment systems and credit cards or other services.
