Reset Network Settings - iPhone

[Agent47]

Hello,

Regarding the above subject title [Reset Network Settings], I have an iPhone 6s on the O2 network.

It states in relation to 'Reset Network Settings' that:

"this also resets Wi-Fi networks and passwords, cellular settings and VPN and APN settings that you’ve used before."

Q:  I am just concerned that doing this will affect my current cellular settings and cause me problems?

Re Wi-Fi networks, all that is really is just putting in the passwords again when you pop round to friends/family etc. 

But it is the 'cellular settings' I want to know how it affects and what changes and will it re-update etc ???

Many thanks.

It just resets all the network settings to nothing but the o2 settings will be immediately restored from the sim card data.

You will have to enter all wifi passwords again though.
