This is a used phone that worked just fine prior to me. What am I doing wrong??
Are you are the same cell provider as the previous owner?
What you want to do after you stick in the SIM and start it up is the following:
Menu button->Settings->Wireless and Network->Mobile
Under Network mode, it should be WCDMA preferred (or it is for me)
Under Access Point name is there anything? (if not then MMS/txt/3G data won't work...but worry about that after)
Under Network Operators, you set what cell provider you want to connect to (might be set to manual, or might not know who to connect to) That is where you need to set the provider
Back under the Settings if the first option is, Sony Ericsson, go in there chose Setting Download, that will download the MMS/data/3G settings from your provider.
Hope that does something to help you.
Oh...one last thing, under Settings->About Phone (at the bottom) Status will show you if you are connected and all the connection stats to your provider.
If it doesn't work...who is your provider and who was the previous owner using?
