This guide assumes you have already created your first Mobile Proxy. The process is very similar to using Residential proxies, but with additional targeting capabilities.

​
Your Connection Credentials

Navigate to your proxy’s settings page in the My Proxies dashboard to get your Host, Port, Username, and Password.

​
Example: Getting an IP from a Specific ISP

Let’s make a request through T-Mobile US. ISP targeting is a separate mode - it cannot be combined with geo parameters (country, state, city). Use the ISP numeric code in the -isp- parameter. 
# Replace with your actual credentials
# -isp-310260 = T-Mobile US
USERNAME="PROXY_USERNAME-isp-310260"
PASSWORD="PROXY_PASSWORD"
HOST="proxy.catproxy.net:5555"

curl "https://api.ipify.org?format=json" \
  --proxy "http://${USERNAME}:${PASSWORD}@${HOST}"
The response will be a JSON object containing an IP address from the selected ISP’s network in the US.
You’ve now mastered the basics of mobile targeting! For a full list of parameters, check out our Geo-Targeting guide.
