You need to manage the memory yourself, this is C and not C++.

char text[100]; // make sure this is large enough
strcpy(text,"Testing Sms");
strcat(text," hooman");

if this is supposed to be c++, you CAN use the + operator with strings, but not char*. you can still use the sim800 send by string.c_str() if it requires a char*.

which language are you trying to use?
