How to Fix Slow Cellular Data on iPhone 12 Pro after iOS 18 update?

I have full bars of 5G reception. When the internet does load, it's extremely slow for a few minutes then it hangs again for up to 15 minutes. I've restarted my phone several times, removed the sim, reset network settings but it didn’t help. Going on 48 hours now of not being able to use cellular data on my phone. No issues at all before update to iOS18. Anyone else having the same issue?

I have the same issue. I have a new iPhone 16 Pro Max and I'm on IOS 18.1 Beta 5. My phone shows that I'm on the 5G ultra wide network, but my downloads are abysmal - typically under 5Mbs. WIFI is fine, but cellular (both at home and at work) are terribly slow, so slow that I cannot update Apps from the App Store. I spoke with my carrier (Visible) and they tried a few things, but nothing has helped. I have toggled Airplane mode, Reset Network Settings, rebooted several times. The last suggestion from Visible was a factory reset. I might be doing that tonight.
