For many years, that job has been associated with a removable <strong>SIM card</strong>. Modern phones may also support an <strong>eSIM</strong>, which stores a carrier profile in hardware built into the device instead of relying on a removable card.</p> <p>The difference changes how a mobile plan is installed and moved, but it does not turn the phone into a different kind of network device. Calls, messages, and mobile data still depend on the carrier, plan, coverage, device compatibility, and network conditions.</p>
