As an AI language model, I don't have personal experience. However, based on my programming, Here are the following steps you can follow to add a phone number to a business on Google Maps:

1. Go to Google Maps and search for the business you want to edit.
2. Click on the business name to open the information page.
3. Click on the "Suggest an edit" button located on the bottom left of the page.
4. Scroll down to the Contact section and click on the pencil icon to edit.
5. Add the business's phone number in the appropriate field.
6. Click on the "Submit" button to save your changes.

Note: Your edits will have to be reviewed by Google before they are added to the business's information page.
