There's a few issues with your script.

pawn Код:

new gMessage[256];
        new Message[256];

These string don't need to be that big, the max displayable characters in SAMP are 128.

You also should add a return at this piece of code:

pawn Код:

if(!strlen(tmp))
        {
            SendClientMessage(playerid,COLOR_WHITE,"Usage: /sms [number] [message]");
        }

pawn Код:

if(!strlen(gMessage))
        {
            SendClientMessage(playerid,COLOR_WHITE,"Usage: /sms [number] [message]");
        }

So the script 'halts' at that line and doesn't continue.

You also don't return 1; on the bottom of the command.

I have no idea how to use strtok, so I won't comment on additional bugfixes, I myself prefer zcmd and sscanf as that's way easier to use and to-date.
