Come on, don’t pretend you weren’t expecting it. After all, I publish this article roughly once with every new version of iOS. (Don’t believe me? Here are the receipts.) Forget about any article that advises you to go into the iOS field test mode. It’s never worked consistently and believe me, I’ve been trying for over ten years. It now seems with iOS 17, you can’t get a signal level of your 5G signal, at least I can’t. If someone else is able to, I’d love to hear how you did it.
Really, you don’t. Really, the most important thing with a cell phone is whether or not you can do what you want. Can you make clear calls whenever you want to? Stream as fast as you want to? If you can, that’s all that matters. However, a lot of people (myself included) get curious about how much better things can get. And unfortunately, cell phones are incredibly stubborn about providing this information.
First of all, I think we all know by now that the bar measurements are near useless. In my area, it’s rare that I get more than one bar, yet my service outside is as strong as it can be. How is this? Because you never know what the bars are actually measuring. Your phone could have as many as five active radios going at one time, never mind the 15 or so that aren’t used because they’re for carriers you’re not on. That bar measurement is reflecting the signal strength of ONE of those radios. Which one? Who knows. That’s the point.
Cell signal is really measured using something called RSRP. RSRP, or Reference Signal Received Power, is the truest form of measurement. It takes into account not only the raw signal strength of what you’re receiving, but the quality and usability of that signal. It’s the only measurement that accurately tells you what kind of reception you’re getting.
When it comes to your phone, it’s using both LTE and 5G, probably at the same time. You don’t notice the difference, but your phone is always switching between the two technologies to give you the best results. Often times, voice calls will stay on LTE while data comes over 5G. Occasionally, it’s the opposite. The two technologies are designed to work together seamlessly. So, if you really want to get a true picture of what kind of signal your phone is getting, you need to know the RSRP for both. Except there’s only one problem.
You can get into the phone’s field test mode by dialing a simple string of numbers:
This takes you to a rather plain and nondescript menu. If you poke around enough you will find a measurement called “LTE Rach Attempt.” Tap on it and one of the numbers is RSRP. It’s a negative number and if you’re lucky, it’s higher than -100 (in other words -80, -85, etc.) and that indicates that you’re coming through loud and clear. There used to be a similar menu for 5G, and now it’s gone.
I don’t even know how to show you that it’s not there, it just isn’t. And without it, you don’t know how strong your 5G signal is.
Well, there are two ways. One’s relatively cheap, and one’s relatively not.
Ideally, what you want to do is have friends with different cell phone providers, all with 5G-capable Android phones. Get them to load an app that shows signal strength, because not every Android phone lets you see this number without an app. There are a lot of them. My personal favorite is called “Signal Strength” and it’s free. Then, get them to run the app while standing in the same place. They won’t need to do it at the same time, since for the most part this stuff doesn’t change. They’ll see a readout of both LTE and 5G signal:
…and that’s all you need. If you don’t have friends with three different service providers, you can buy an unlocked prepaid phone and three different SIM cards. You may not find them for AT&T, Verizon, and T-Mobile, but each of these carriers wholesales their services to other carriers. Just look at your selection and google “What carrier is Cricket on” or whatever service you’re looking at.
Yes, this is a pain in the neck. There is a better way.
This impressive little kit is the WilsonPRO 5G Network Scanner. It’s a sweet little piece of gear that connects via Bluetooth to your phone (iOS or Android.) It reads ALL the 5G and LTE signals in your area and displays the RSRP for all of them. In about 4 minutes, you’ll have a complete record of all your signal strengths and you can even download them into Excel, complete with GPS coordinates.
But let’s be honest with each other. It’s not cheap. If you’re only going to use it once, it’s a big expense. Of course you could buy it with a credit card and sell it on eBay before you get the bill, but that’s up to you. It is returnable to Solid Signal but if it’s not defective, there is a rather sizable restocking charge. That charge is essentially there to stop people from using it once and returning it.
Even if you end up buying a prepaid phone and 3 SIM cards, you’re probably out about $125. The Wilson Pro meter is about ten times that price. Isn’t there something in the middle?
Unfortunately, not really. There are other cellular meters out there but they generally do not read RSRP. They’ll read most of the low-band frequencies that you get, but all you get is raw signal strength, a measurement known as RSSI. This is fine if it’s all you have, but it won’t tell you how good your actual signal is or isn’t.
That’s why it’s so disappointing that Apple is hiding this essential number from us. If all you want to do is figure out how your particular network is doing, you should be able to do it. Really, that isn’t classified information. Yet, Apple makes it hard to get, and in some cases like the current iOS 17.1, it’s impossible.
Whether or not you can actively measure it, a cell phone signal booster can help you get clearer calls and faster data. You’ll want to take a look at the great selection we have at SolidSignal.com.
