On iPhone 6s iOS 12.2, the code *3001#12345#* doesn't show me the GSM signal. How could I solve it?
iPhone 6s, iOS 12
How about the signal bars in the status line?
After entering your code tap on LTE, then Serving Cell Meas.
rsrp0 is the signal strength of the nearest tower
rsrp1 is the signal strength of the next nearest tower
That's not a documented customer facing feature of the phone. There is nothing to "solve".
If it doesn't work properly, make arrangements with Apple to have it examined.
That 6s is 4 yo... I have to pay for a check at Genius Bar...
The Field Test info comes from your carrier. It looks like they are not providing it for your account. Does anything come up if you tap Measured RSRP?
hmm. My phone is out of care. How can I measure the GSM signal?
As I said, that is NOT a documented feature of the iPhone.
Ok. Any app in the store ?
Try a search for one.
No found...
If there is nothing available in the Apple App Store, then there isn’t an app for that.
Other ideas?

Why do you feel you need to do this?
No, you don't have to pay to have them look at the phone.
Actually, it does show the GSM signal. It shows it in much more detail that it used to. So much detail you need to understand the GSM standard to interpret it.
GSM signal power *3001#12345#*
