Contact your mobile network provider for assistance with this matter.
I think it should be the 17th pro max issue，due to this sim card working well in my 16 pro max。Overall，iPhone mobile network speed performance always behaves worse than my xiaomi 14 ultra and Huawei mate 60 pro.
I’m from Taiwan, and i also encountered the same trouble with my 5G network, even though the signal bars were full, but when you try to have ping utility test, the latency of network extremely delayed, causing some disturbance to browse, gaming and chat reply. But weird thing is my iphone 17 pro max is working well with my wifi network. And even tried the same sim works fine with my previous iphone 15 pro max that also has a ios 26 ready.
