Data Stopped Working - iPhone 13 Pro Max

Same issue since buying the 13 pro max went to several stores and they all are clueless only can get internet via WiFi I'm a sprint carrier but did the swap but pay too if line premium and for what I can't use anything finally got 1 rep to change my virtual esim to a card and phone now works but all pic texts say failed to send but everyone says they recieved but still no data unless on WiFi it's been 2 months and everyone looks at me like I have 3 eyes or something and says idk and sends me on my way! Like really? Idk I feel like it's cuz I'm sprint but did the T-Mobile swap but now I can only think maybe faulty phone has to be what else? So was hoping I wasn't only one and that I could find someone with a fix myself so at least I could use my gps while driving in a my phone that I pay for as well as the data I pay for on. MY not so cheap plan I pay for! Ughh
