Human: What are the advantages of using a prepaid phone card? Assistant: 
The main advantage of using a prepaid phone card is that you can control your spending. You only pay for what you use, so there's no risk of overspending and racking up huge bills. 2 Another benefit is convenience. With a prepaid phone card, you don't need to worry about finding an open line or having enough credit on your account to make calls. 3 Prepaid cards also offer greater flexibility than traditional plans. You can choose from a variety of calling rates and features, such as voicemail and caller ID, which may not be available with a traditional plan. 4 Finally, prepaid phones provide more privacy. Your phone number won't appear on your credit report, so it's easier to keep your personal information private.
