Please help me to resolve this problem.

You have installed a module MN_Sendsms but you have not uploaded the Data.php in Helper folder. If you have uploaded then the name varies with the one you mentioned in config.xml — Afroz Alam
Thanks for your reply. How to add Data.php file and where it will find? — Kavita

Make sure this file exists:

/app/code/local/MN/Sendsms/Helper/Data.php

local or community in above path depends on where you have put the module

If not then it creates this class:

class MN_Sendsms_Helper_Data extends Mage_Core_Helper_Abstract
{
}

And make sure in the file

app/code/local/MN/Sendsms/etc/config.xml

<?xml version="1.0"?>
<config>
    <global>
        <helpers>
            <sendsms>
                <class>Mn_Sendsms_Helper</class>
            </sendsms>
        </helpers>
    </global>
</config>
