Here are some tips to boost the signal strength on your iPhone:
Move to a location with better coverage:
The strength of your iPhone’s signal depends on your proximity to the nearest cell tower. If you’re in an area with poor coverage, move to a location with better coverage.
Enable Wi-Fi Calling:
If you have Wi-Fi at home or work, enable Wi-Fi calling on your iPhone. Wi-Fi calling can help boost the signal in areas with poor coverage.
Reset network settings:
Go to Settings > General > Reset > Reset Network Settings. This will reset your Wi-Fi passwords and cellular settings, so you’ll need to re-enter your Wi-Fi password and configure your cellular settings again.
Toggle airplane mode on and off:
Sometimes toggling airplane mode on and off can help refresh the signal.
Update your iPhone’s software:
Make sure that your iPhone is running the latest version of iOS. Go to Settings > General > Software Update to check if there is an update available. If there is, install the update.
Turn off LTE:
Turning off LTE can sometimes help boost the signal. Go to Settings > Cellular > Cellular Data Options > Voice & Data and select 4G instead of LTE.
Use a signal booster:
You can purchase a signal booster to boost the signal strength in areas with poor coverage. Signal boosters work by amplifying the cell signal and then rebroadcasting it to your iPhone.
Use an external antenna:
Some iPhones have the option to connect an external antenna to boost the signal strength. You can purchase an external antenna online or from a mobile accessory store.
Note: Be aware that in some cases, boosting a signal can be illegal, especially if you’re using a booster or repeater that hasn’t been authorized by your carrier. It’s always best to check with your carrier before using any signal-boosting devices.
