Are you having problems with poor reception on your iPhone? Fear not, as this guide will walk you through how to check your iPhone’s signal strength and antenna reception in just a few steps.
How to Test Your iPhone’s Signal Strength and Antenna Reception
To begin, ensure you are running iOS 4.1 or later. Then follow these steps:
- Dial *3001#12345#* on your iPhone.
- Tap Call to bring up the field test mode.
- You’ll notice that your signal bars have been replaced by a negative number – the lower the number, the weaker your reception.
- If you tap the number, you can switch between signal numbers and bars.
- To exit field test mode, simply press the home button.
It is worth noting that the number you’re dialing is actually a field test that has been carried over from the original iPhone 2G. This test can help you determine whether your iPhone’s own antenna is at fault, despite AT&T’s network having been criticized for poor reception in some areas.
