Is there any software that can increase the no. of characters written in sms than ususal 150 char.

More Characters in 6630 SMS
Just keep writing (and the usual limit is 160 characters, unless you use characters that require switching to Unicode encoding and you get 70) and a longer message is created and sent (in multiple parts, and the receiver's phone will reassemble them and show them as one).
This is assuming your network operator has not restricted messages somehow. The phone itself shouldn't (and all the 6630's I've had, have not had any problems with long messages).
