If you're using an iPhone or iPad running on iOS 11 or iOS 12, you're probably getting into some safari issues, such as Safari crashes frequently after launch, Safari gets completely frozen, there is no response on Safari, webpages cannot be loaded normally, website interface is unconnected, etc. Surely, Safari not working on iPhone or iPad issue must have caused a lot of troubles for you. To get you back on track and enjoy your iPhone/iPad, here we prepare some tips as follows.

1. Authorize Cellular to Safari and Switch Network

First at all, you are supposed to have a check on your iPhone settings to see whether you have allowed your Safari app to use cellular. That is to say, you should give right to web browser to access to the cellular data. To do it, you just go to "Settings" > "Cellular" > "Safari" > toggle switch to green "ON" status. Likewise, you can change a different and strong network and open Safari again in case the network is unstable or too weak.
