Note here, it is very dangerous to give your merchant phone to anyone for that person to do settings for you to use it to register mobile money customers. It is not done and if you give your phone to such person remember you are going to lose something heavy, that fraudster will surely ask you to give your pin to him or her because you need to change your pin for the process, now immediately you give your pin, he or she will transfer your money on your merchant sim into his or her account which you won't be aware of it, because the person will tell you to switch your phone off for about thirty minutes for the settings to go through. So by the time you switch the phone on that fraudster would have left you already and had taken your money and gone. Because immediately he or she leaves you the person just moves to another merchant to take the money that was transferred from your account. Make sure at all times you deal with your network operators directly no third person, call your operator call center number and ask questions about anything that intricate to you.
