Got new sim card for new phone, employee I bought it from told me I must download app to activate it. Once I downloaded and opened this app it had no such option. I then went online and eventually found where to do this and put in new sim card number. Once I tried making a call on my new phone I realized that instead of my phone number the phone now has the number of a family member on the same account. Her phone does not work at all. I don't know how this happened. What do I do, I need this fixed immediately we both need out phones for work.
