Solved : It was indeed the network parameter of my mobile operator! I tried with another operator and it worked! Mobile data, MMS and mobile access point. Screenshots of the changes made to put back the correct settings. I also inserted Waydroid to find the applications I use: It also works. Thanks for the tracks.photo_2022-05-19_11-40-32.jpg photo_2022-05-19_12-12-58.jpg
