How can I check the signal on my phone?

To check the signal on your phone it is not enough just to look at the bars on your screen as it is not a precise indicator, that’s why we recommend you to turn to a more reliable way of checking it. To do it, you need to use Field test mode (FTM) on your cell phone. This function is available on the majority of modern operating systems on smartphones. Below you will find short instructions but if you need more details, please, check this page.

  1. If you have OiS phone, dial * 3001 # 12345 # * and press “Call” button.
  2. If you have Android device, dial * # * # 197328640 # * # * and then hit “Call” button.
  3. If you use Windows phone, dial Type # # 3282 # and start.
  4. If you have Blackberry device, select TOOLS, SETTINGS, STATUS or OPTIONS, STATUS.

How should I interpret the results of Test Field Mode?

After you activate Test Field Mode on your cell phone, on the screen you will see the indicator of your signal power in dB. For more information about Test Field Mode, please, read the information provided on this page.

The dB parameter is a negative number. The higher is the number (the closer to zero it is), the better signal reception you have.

To have reliable communication and high quality of your cell signal, your aim is to reach a mark of at least -79 dB.

How should I point my antenna to let it catch the best signal?

Ideally, your antenna should be pointed to the direction where the nearest base station of your carrier is situated, but if you don’t have precise information on its location, here are some tips for you how to find the most appropriate direction of your antenna.

  1. Install the whole set of you cell signal booster, including antennas and cables. Switch the system on.
  2. For finding the best position of the antenna, you need a helper who will be checking the power of the signal, while you will be changing a direction of your antenna on the roof. Choose a concrete direction. Your helper should be inside, checking the level of the signal that his or her cell phone is receiving (the best way to do it is to use Test Field Mode).
  3. Then your task is to rotate your antenna for 45 degrees (that is 1/8th of the circle). The person who is indoors, should wait for a minute and check the signal level once again.
  4. You need to repeat this procedure for 8 times, each time changing the direction of your antenna for 45 degrees.
  5. When this task is done, you need to analyze the obtained results. When you compare the results, don’t forget that the signal level is estimated in dB which is represented in negative numbers. The closer to zero it is, the more powerful signal you have.
  6. Point your antenna to the direction with the best result.

It is recommended not to direct your antenna to the side of the building as it may become an obstacle on the way of your signal.
