Last year, Verizon gave me the unlock code for my Droid Pro so that I could use other sim cards while travelling overseas. It worked perfectly. I have been using a TIM sim in Brazil for local calls and 3G access. Recently, I did a factory reset to clear unwanted items from my phone. What I did not realize was that factory reset apparently affects the ability to connect to 3G. I've read somewhere that it is necessary to dial a special number (*228 I think) to have the phone reactivated.
But, there's more; because I am working on a project in Brazil I can't use that number. Plus, I won't be returning to the USA for another year. Also, I recently cancelled my Verizon service (and paid the early cancellation penalty fee). Since, I had not used 3G since the reset or the cancellation I am not sure which (if either or both or something else) has caused the failure to connect to 3G. When I check in the About Phone settings, it says I am disconnected but provides no other info. Yes, I did have everything else turned on.
Btw, I am able to setup tethering and a hotspot and connected to my laptop. However, there is no internet connection available. The WiFi still works fine and I am able to make calls using my TIM sim and, prior to the above described changes, I had successfully used 3G on TIM with no problems. Also, the sim card works OK on another phone (3G included).
I have heard there is a way to manually fix the problem (without dialing *228) but I have no idea what it is or where to find that information. Can anyone please assist with this problem?
