I am looking for people who are familiar with IP addresses and mobile networks.

Thank you for taking a look at this project. I am currently looking for someone who can help me with the following requirements for an IT project in Japan. [Background to the project] My client has more than 50 iPhone devices and more than 50 SIM cards under contract in order to purchase or enter into lotteries for popular products such as PS5. However, as the number of devices increases, the number of manual operations increases, so he asked me if I could automate the process. So I considered the following Is it possible to use an API service where the device is programmatically disguised and the communication line provides a 4G line (mobile network) and a phone number [Problems] 1. I couldn't find a service that provides a mobile (4G) communication line. 2. I couldn't find a service that provides the phone number required for SMS authentication. However, using a mobile network such as "Bright Data", which is a proxy server service, is no good because it does not provide a phone number for SMS authentication. If anyone can solve these two problems, I would appreciate a message from you.
