I am on my original Maxx pusrchased in early February and this is the first time my SIM card has been changed, until recently my phone has functioned perfectly. I am pretty sure Verizon is aware of this problem. It just seemed to easy to get the solution to my problem. Normally you call tech support and they walk you through a bunch of worthless steps to try different things and then eventually end up ordering you a refurb. This time as soon as I explained my problem the guy said it sounds like it's one of two things either the phone is bad or your SIM card is bad, he then asked me to give him my PRL number from my phone. After that he recomended that I try a new SIM card since my phone was working perfectly other than the new data drop problem. Since replacing the SIM card on Sunday afternoon my phone has been working perfectly again.
