Yes, we offer real dedicated proxies. No one will be sharing the SIM card with you. Each SIM has its own modem and is locked to 1 IP address for authentication to prevent sharing.
Our Proxies can be setup as the client wishes. From as little as 5 minutes to as long as the ISP allows. Each SIM card can have its own custom IP Rotation policy. Let us know what you need and we will set it up.
