I have not used mobile proxies before, I have XXX regular server private proxies without rotation, how many mobile proxies do I need to give up server proxies?
Each mobile proxy has a pool of IPs (1K-50K unique ip), but it is impossible to connect to this pool at the same time, connection is sequential 1 proxy = 1 ip from the pool. To get the next IP, you need to execute a url request, the request is executed for 5-15 seconds, during this time the proxy is unavailable and rejects all requests sent to it.
Therefore, first you need to adapt your template/software to work with mobile proxies, test the work on several mobile proxies, then scale. In tech support you can specify contacts of the developer who is engaged in adaptation of zenka templates
