No, however, we do have overage for Plans which exceed yearly SMS credit limits. Overage is charged on an annual basis at the renewal anniversary date.
We do not charge a setup fee as we have designed WhosOnLocation so you can easily set-up your account and optimize it for your needs yourself. However, we recognize that many of our users are busy and we offer a number of packages for WhosOnLocation to set-up your account for you. Contact our Customer Support Team for more information.
