Hello,
I have older DSL Classic M Flex tariff and i would like to upgrade it to the DSL Home L Flex.
It is not possible to do the request via my account and i was a bit lost when i tried to call the customer service.
Thank you so much in advance

Hi
welcome to our community. 
Unfortunately there is no chance to change a DSL contract online. We can arrange everything but have some questions first.
Do you wish to keep the monthly cancellation period or are you interested in a 24 month contract with a special offer?
Do you have a router to your contract and wish to keep it?
Please be aware that the flatrate to german mobile networks is no longer included in the new tariff.
Get back to us if you need some more assistance.
Greetings
Hello o2,
thank you for the answer. I am interested in DSL Home L Flex tariff (with monthly cancellation). I got o2 box 6431 router from you (6 years ago). If the router is still usable for the higher tariff, i am fine to keep it (if it is without any fee). If not, i would prefer to buy new router by myself.
Regarding the phone, I do not use it, so i am fine with that.
Thank you!
Fine
you can keep the box for free if you like. I will arrange the change for you within the next days. As a little benefit I will set a discount of 5 EUR for the next six month to your tariff.
Greetings and stay safe
Thank you so much!
I hope the tariff will be still with monthly cancellation.
Vielen Dank!
Amazing!
Thank you
