You can add the i option(meaning replace in place):
Code:
sed -i 's/^821910002022,smartlimit/1234567,Nonstop/; ' infile

You cannot replace the string and save the file at the same time using sed, below code will help you to achieve the objective.

Code:
#find and replace the string and save it a temp file
sed 's/^821910002022,smartlimit/1234567,Nonstop/; ' infile.txt > temp.txt
#rename the temp file to original file name
mv temp.txt infile.txt
