Mobile proxies are used where the address needs to inspire maximum trust and change — either on schedule or by your command.
Typical tasks
Working with services that strictly verify the origin of the address and do not allow data center addresses.
Checking ads and search results as seen by a mobile internet user.
Tasks where the IP needs to change on schedule or at a specific moment.
Testing mobile versions of websites and applications.
Working with regional services of a specific telecom operator.
When to consider another format
Mobile is the most expensive format, and the address is not constant. If neither trust nor address change is decisive for the task, there are cheaper options:
If the address should remain unchanged — IPv4 or ISP.
If you need many addresses at the lowest price — IPv6.
If you need wide coverage across countries and cities with constant rotation — Residential.
