Goodbye T-Mobile

Ever since my phone plan got cancelled with Vincent because we didn't pay our bills, I would ALWAYS depend on my parent's spare phone & use it & add text message for my own benefit. Recently, my mom told me that they are planning on cancelling their cellphone contract with T-Mobile because their 2 year contract was over, but I doubted them. Now, 2 hours ago, my cellphone suddenly lost signal & then it popped up an error message that said it could not recognize my sim card and could no longer register it...so I was like whaaa?! So I decided to go on T-Mobile.com to see what the problem was, turns out, T-Mobile told me I couldn't log onto my account or access it anymore because the phone number I had, is now cancelled. How sad! I've depended on this phone ever since summer of 2009 when my family threw away my sim card with Vincent. Now, I have nothing besides Vincent's company phone which I don't know how to use at all...I'm so sad. I also worry because I'm afraid Vincent's going to need this phone eventually & give it to one of his patrol officers, so what then? What phone WILL I use? I always gotta look to the future & figure things out for myself.
