Hi, I have an O2 homespot contract and would like to register it in meinO2 app in order for me to access my bill informations, but upon registering it seems that I need to enter the mobilfunknummer which I can't find in the simcard package, there's only Simkartenummer. Is there a possible way to know what my mobilfunknummer of my homespot sim card?
Thank you and hoping to get some answers.
