my phone will not connect to my Wi-Fi. My iPad which is sitting right next to it is connecting

Greetings, Helptoconnect

Welcome to the Apple Support Communities. It sounds like you’ve isolated the issue to your iPad, since your iPhone connects to Wi-Fi without issue. We can understand why you’d want to resolve this. 

On your iPad, complete the steps shown, here: If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network

If the issue continues, consider answering the following questions. 

1. What happens when you try to connect to Wi-Fi?
2. Do you receive any error messages? If so, please provide exact wording. 
3. Which iPadOS version are you using? (Settings > General > About)

All the best.
