iPhone cellular data is very slow
Slow cellular is from weak signal, network congestion, your carrier throttling you after high data use, or a settings glitch. Try toggling Airplane Mode, checking signal strength, and resetting network settings.
Cellular data speed depends on your signal strength, how many people are using the network in your area, and what network you're on (4G or 5G). Slow speeds come from one of these: weak signal, too many people on the network, a settings problem, or your carrier throttling after high data use. We'll test each one.

Skip — I just want a technicianCommon mistakes to avoid
- Assuming slow data is always your phone's fault — it's the location or carrier throttling
- Not checking signal bars first — 1-2 bars naturally means slow speeds
- Forgetting that you'll need to reconnect WiFi networks after resetting network settings
Signs you need professional help
- You have 4-5 bars and speeds are still incredibly slow after trying all these steps
- Your carrier says there's no issue but you still can't use data
- You suspect your SIM card is damaged
