如果不按 send, 電話紋絲不動。
如果按 send, it dials whatever I entered. I hear calling ring echo and then an old man voice said 'Your account can not be validated, please call customer service'.
這個電話以前的主人一直在sprint用，應該還是sprint的ROM。
我在猜, maybe ##...# pattern is not mapped to programming command invocation on this phone. that is why after pressing the last #, it does not do anything.
