Hi, I recently returned to the states after traveling to Japan for work. While I was in Japan, I bought and used a sim card for their Network. When I returned to the states, I switched back over to my Verizon sim card and have been having trouble ever since. My data seems to only be able to have a very weak 3G signal (1mb up/0.9mb dw), which drops frequently. When I returned to America, I contacted tech support and after trying just about everything, I went ahead and just factory reset my phone. After which, I am still having the same problem. I only get a weak 3G while in global, or LTE/CDMA. And whenever someone calls me, my data completely drops. I have even gone to a Verizon store and received a new sim card. Still the same issue. Now, Verizon has told me that I should replace my phone. I filed a claim for a new one. But I have to pay $80? I am paying for insurance, so I don't know why I need to pay $80 deductible.
