title: Can we fix (stable) the public IP address of mobile?
body: <p>Can we fix the public IP address of a mobile device?</p>
  
  <p>In detail: Suppose I am traveling to different states of the country with a smart phone in which I have internet through a GSM SIM card. Its IP address is changing after some time interval. </p>
  
  <p>I am referring to the public Home IP address - that we can find by surfing to <em>WhatismyIP</em> which gives, as an example, <code>145.233.66.202</code>. But after 2 days or after some hours if we check then it will have changed (like <code>149.222.33.12</code>) from previous one.</p>
  
  <p>I want to make it stable; I want to use a static IP address.</p>
  
  <p>Can I do it? Then how? Please share your idea with me.</p>
