Hello, thank you for the responses @Bumer and @o2_Gerrit . I emailed the cancellation request to given email address. I have one more question about Prepaid card. I have o2 Loop Prepaid card, which allows me to have Data packs with validity only for maximum 1 month. I am looking for something with more data and with validity of 6 months or 1 year or so. Then I found this pack of yearly 100 GB, which I found cost effective. But I dont understand this need to buy new SIM card and new number. Can't I just make this recharge for yearly data like 100 GB or something? What is the solution? I dont want to loose this number.

The solution would be to order a new 100 GB card and transfer the phone number to it.

internal porting form

o2 does not offer a change to the annual package.

Hello @Abhi30 ,

has anything been answered and solved to your satisfaction or is there something that we can still do for you? Please let us know.

Kind regards, Sven
