How do I set up tumblr to my phone?

Please Help! T-Mobile Prepaid Phone Set-up?

• Hello, Recently I bought a new T-mobile phone to use for their prepaid service. I had an old T-mobile prepaid phone, so I figured I could keep my phone number if I just put in my old SIM card into the new phone. So, I charged the battery in the new phone and put in the SIM card, but on the screen it showed "No SIM Card" and I couldn't make calls or do anything. I called T-mobile customer service and gave them the 15-digit code to activate my phone, and they said it would take about 2 hours for my phone to start working. It's been about 20 hours since then and I have no idea what to do next to set up my phone- could someone please help me by telling me what exactly I need to do to get my new phone working? Thanks so much!

  put in the new sim card activate it like you normally would and then just have them transfer your old number to your new phone :) hope i helped!!!
