iPhone signal strength

Question

I know this question has been floated, but there are not any answers. In Objective C, is there a way to return signal strength?

Answer 1

It's not documented API I believe, but you may git clone VAFieldTest in Github. Search int result = CTGetSignalStrength(); in this app. See the selected answer here: Measuring cellular signal strength

If you just want to see the signal strength, call *3001#12345#* in the Phone app and it will shown in the status bar.
