Send at command to read news, the timeout! How to solve?

            


I have a very long message, the following information:

"Czech local media analysts say, due to fears of trade relations, the Czech government had never dared to support" Tibet Tibetan flag, "but Hu Jingtao"

With the at command to read it, timeout time at the command set is large, but read or overtime, how to read a long message?
I send a short message can be read :(, which is why you?
