I will be leaving Germany for half a year (January-June 2020) and I am wondering if I could ask O2 to freeze my account while I am abroad as I am not gonna be able to use the service at all.
Is this even feasible? I left for half a year few years ago and they changed my tariff to the most basic one. During that period, I needed the sms service working for online banking transactions. This time, I wont need the service at all.
I hope someone could help.
