You can research that further. But that reset should never erase what's on the SIM card.
Some folk need a reminder on those 2 areas.
I bought this phone used & locally from a private party.
It is for Cricket. I still have 2 months left on my tmobile contract. So when my contract with tmobile expires, I MIGHT decide to switch to cricket, or another carrier.
I know the vitality works cause it is in pristine condition.
I have been using the wifi too.
But even though I got the phone with the previous owners info erased, there is something that was not erased.
It is his former phone number in the settings part
(about phone>status>my phone number).
I redid a reset on the phone myself but it wont clear out his former phone number.
So in the event that I choose to stay with tmobile longer, I may end up selling this phone. But, whether I keep it or sell it, i want this info gone; just as if it were a brand new out of box phone.
What can I try.
Thanks in advance.....
