Use the wifi-integrated phone call system to save mobile credit

If you want to save more with the cost of mobile phones, there’s no harm in you using social media applications that are also equipped with phone facilities, such as Whatsapp, BBM, Line, Skype and other applications. You can use phone facilities by first connecting mobile profiles with internet or Wifi signals. This way, you do not need to waste a lot of credit to make calls to different phone numbers with you. In the meantime, you may go to if you require a service which allows you to convert your cellular credit into money.

However, this one system also has few barriers when your location is not equipped with an internet network or limited 4G signal (in some countries and area). Therefore, to overcome this, make sure the signal on your mobile phone is full and make sure you are in an unobstructed location of buildings or tall plants that can generally hamper signal distribution.
