I have had a ZTE warp for about 2 years or more now. The speaker (where I talk into) on the phone has went and no one can hear me when I call or when they call. It first was just breaking up (started about a week ago) and now it just doesn't work at all. I have another ZTE warp (n680) that was my brothers awhile back and was activated once, but he stopped using it not too long after. I want to use his phone now, but I can't simply put my sim card in and just have it working, it wants me to activate it by calling 611 but I don't have phone service so it doesn't go through. I also can't call 611 (care service) to talk about it on my other phone because the speaker doesn't work. How do I use this other phone?
