I really need help. I'm traveling in Taiwan now and I purchase a LOCAL prepaid sim card. I insert the local sim card into my HTC incredible phone, but it's not working at all. It kept saying no sim card inside. I remember when I purchased this phone at verizon store, the sale rept told me this is a global phone and when we're traveling, we can simply insert the local sim card and it will work. BUT now, it's not working at all. I also when to HTC store in Taiwan, and they told me it's probably because it's locked phone, and I need to ask verizon to unlock my phone first in order to insert a local sim card from other countries ??? Is that true ? and why I was not told when I purchased it ?? How can I get my phone unlock while I'm currently not in the Sate ? HELP~~
