Hi, I am having following two issues: a) Data does not work in 3G in my iPhone 11 Pro max. Data in 4G works fine. Whenever, 4G is not available my phone switches to 3G, but then data download doesn't work in 3G. I can make call, however. b) In "Setting>Mobile>Mobile data Options> Voice & Data>" only 4G, 5G are available, not 3G. How do I select 3G? (However, whenever 4G is not available I can see 3G bar at the right/top corner, but data doesn't work). Regards,
