I recently had T-Mobile store switch out my SIM card and discovered that I had lost the majority of my contact list. I do see the entire list on the T-Mobile website. Can I download that list from the website to my phone?
If you have three old Sim card just put that back and copy numbers into your phone memory.
I did that, I my old SIM card did not show my original list of contacts...it showed the minimal list I see in my new SIM card.
