Dialling the code *3001#12345#* on iPhones reveals real signal strength
It can help create a reception map of a user’s home to find the best signal
Going upstairs and opening a window can improve mobile reception
Resetting the phone or turning on airplane mode briefly can also help
Mobile phones are meant to allow us to be in contact no matter where we are, but for some people the devices can prove difficult, even their own homes.
Signal failure is one of the most frustrating occurrences of modern life as calls drop out mid conversation and text messages stubbornly refuse to send.
But there are a few simple tricks that can help to ensure you can stay connected.
Searching for a mobile phone signal can be a frustrating necessity for many people who struggle to get decent reception in their own homes. However, there are a handful of simple tricks that can improve mobile signal. A stock image of a woman searching for mobile reception is pictured
These can be as simple as climbing the stairs, opening a window and using new technology designed to boost your signal inside.

BOOST YOUR WIFI SIGNAL
Like mobile phones, WiFi routers use radio waves to communicate with electronic devices.
However, these have a relatively short wavelength and power, meaning they have a maximum range of just a few hundred feet. Walls and other obstacles can also block this signal.
To improve Wi-Fi, placing the router in the open with a clean line-of-sight to where you are most likely to use the web can improve the connection.
Lifting the router off the ground can also ensure the radio waves have the best chance of getting around the house without being absorbed by hard flooring.
Other electronics can cause interference with the signal, so it is good to keep the router away from PCs, televisions and other devices.
Devices also work better if their internal antenna is aligned with the aerials of the router, so if the router has two antenna, position one vertically and one horizontally.
Elsewhere, apps help measure the strength of Wi-Fi around the home to help you find spots to avoid and those that give the best reception.
1. How strong is your signal?
First, it is important to find out how strong your signal actually is.
While the bars on mobile phones are designed to give an idea of signal strength, they are not consistent across handsets.
People iPhones can find out what the actual signal is by dialling the code *3001#12345#*.
This takes the phone into a hidden ‘field test’ mode.
The actual signal strength measured in decibel-milliwatts (dBm) will be shown on the top left where the bars were.
To get more details select ‘serving cell measurements’.
For those with an Android phone, look for the ‘signal strength indicator’ in settings.
The higher the dBm number the better the signal – for good conversations it should be somewhere above -100dBm as below that number signals become patchy and calls can fail.
2. Make a signal map
Using your phone’s signal strength, walk around your house to look for the areas with the strongest signal.
This can help you identify the areas that give the best reception.
3. Open a window
The walls and the insulation they contain can block signals from nearby mobile network towers and prevent your phone from communicating with it effectively.
By opening a window you can increase the strength of the signal reaching your phone.
