Hey guys, I've had this Nokia N70 for a while and it's not exactly the best of phone but I can tolerate it. For a while it didn't bug me but now I'm getting quite annoyed with this one problem. When I'm writing an sms that at least fills the screen or more, once I send it I get a warning saying "Maximum message length reached. 2 messages will be sent"

All my previous older nokia phones had no problems like this, is there a way to increase it somehow?

Thanks.
