New Improved Field Test Mode in iOS 18 shows live signal strength

[d5aqoëp]

iOS 18 Finally gives us the useful info about signal strength we all wanted to know from Field Test App. To get this app to show up, you need to install the iCloud shortcut and follow specific instructions which are very easy. This works on iPad and iPhone both.

This post by me will help you to enable it

Here’s a way to access Field Test Mode on iPad Cellular

iCloud Shortcut that still works. Well technically, but not directly. Let me explain. Once you add the shortcut, if you try to run it you’ll get an error message: “Open App failed because the App could not be opened.” No worries, just press the (…) icon on the shortcut. Once you’re on the new...

That's awesome as is your Home Screen shortcut to access sit (I'd never remember the complicated keypad thing).

Interestingly on iOS 18 beta 2 my cellular service stopped working in Canada and using field test I found out that's because its found a Verizon (US) signal in Canada (I'm near the border) which is almost zero signal strength instead of the much stronger Canadian local signal which I'd prefer to use with my unlimited roaming plan. Not sure there's a fix but at least I know what's going on.

I am running iOS 18.0 (22A5307i). Field test mode looks great, but I would like to see the Cell ID number. I am just about dead center of 3 towers. Even with a yagi pointed at one tower for our booster, our devices still tower hop a bit. I used the Cell ID to determine which tower I was on. I know I can use the PCI number, but the Cell ID was just more convenient, I guess. Does anyone know of a way to access the other info that used to be available? Also, my shortcut still works , and I use cellmapper.net.

Cell ID has returned! 🥳

It was always there for me. It just takes some time for it to show up.

I actually don't like this new FTM. It has no timestamps when the given info had updated. the 5G info is really slow to update vs the LTE stuff.
