Human: I'd like to know which is better: a prepaid cell phone plan or a pay-as-you-go plan? Assistant: 
Prepaid plans are generally cheaper than pay-as-you-go plans, but you may have to pay activation fees and/or cancellation fees. Pay-as-you-go plans can be more expensive up front, but they typically offer lower monthly rates. Ultimately it depends on your budget and how often you need to use your phone.
