When booking an escort from the Mumbai escort agency, you can use an online medium like a website as it is considered safe. It is suggested not to use your private phone number or the number that is used in your office or residence. 

Remember that the less personal details you share, the more secure it becomes for you. This is because if you use your own number to hire an escort from a fraud agency, then they might disclose it to others or they may blackmail you for money. Also, you would not want anyone in your family to know that you have ever hired an independent escort in Mumbai.
