Everywhere we go her D2 shows more reception bars than my thunderbolt...yesterday we were at the mall and my phone had no bars while she had like three. I took mine to a Verizon store and ask them so they wanted to exchange it with a refurbished one but I told them to just change the Sim card and see if that would do the trick but nothing. The guy said that exchanging the phone would be better im skeptical of getting a refurbished phone... What do you guys think?
