What proof of residence can I use for my application for a social security number?

I have been resident in France since April, having owned my French house since 2020. I have been asked to provide the last 3 months of utility bills to prove residency, but my EDF bills were regularised (annual facture) until I had them changed to monthly in August. I use mobile data from my French Lebara mobile account, and I submitted monthly payment to Lebara but I have now been asked for landline telephone or internet provider bills for the last 3 months. I don't have a fixed telephone and I don't have an internet provider because I use mobile data from my French Lebara mobile account. What else can I provide as proof of residency?
