I can only adds funds to my account. When trying to add data or change plans there's a message saying phone and sim are not paired. I try to pair them and get a message saying the phone is paired to another account. I didn't have this problem when I bought the phone and paired it with the same sim card that is in it now
Oh no, I'm sorry to hear about the issues you're experiencing with your service. I know how I depend on my phone for just about everything. I'm more than happy to take a deeper look into this to see if we can pinpoint what's going on, this way it can be resolved quickly. Is this for a prepaid account? How exactly are you trying to add funds/change plan?
