Hello @Sweetsraboni ,

welcome to the o2 Community .

Have you registered the contract to mein o2 that you are trying to access through the app? Do you also get this message when you are going directly through a browser instead of the app or does it work there?

Kind regards, Sven

Hi.

My browser login works fine. Just having the issue with app.

Hello @Sweetsraboni,

What kind of contract do you have with O₂?

Best regards

Hello, I am using O2 DSL connection for home internet.

Hello @Sweetsraboni,

Have you registered your landline number here?

Best regards

Hello @Sweetsraboni ,

how are things looking like on your end, we didn’t hear anything further from you. Were you able to log into the App with your DSL contract as you had hoped to.

Kind regards, Sven
