BYOD stands for &quot;bring your own device.&quot; It&#39;s a term used to describe bringing your own mobile phone, smartwatch, or tablet to a wireless carrier instead of buying a new device from the carrier. Similarly, &ldquo;BYOP&rdquo; stands for &ldquo;bring your own phone&rdquo;.

If you like your current smartphone, tablet, or smartwatch, you can BYOD to AT&amp;T and quickly switch carriers. In most cases, your current GSM-compatible smartphone, tablet, or smartwatch will easily connect to AT&amp;T&rsquo;s network, so you can keep the device you love.

There are several key benefits to bringing your own phone or even a smart device like a tablet or smartwatch.

<ul>
	<li>You may have just finished paying off your device with your current cellular provider. Even if you didn&#39;t buy your device from AT&amp;T, you can keep your device and simply add an AT&amp;T wireless plan to get new service connected on that device.</li>
	<li>When you bring your own device, you won&rsquo;t need an AT&amp;T Installment PlanSM&nbsp;since you already own your device.</li>
	<li>You&rsquo;ll even be able to keep your current number if it&rsquo;s eligible for&nbsp;<a href="/wireless/transfer-your-number/#PORT_ELIGIBILITY3">transfer</a>.&nbsp;&nbsp;</li>
	<li>Enjoy exclusive offers when you bring your own device to AT&amp;T.</li>
</ul>

SIM cards are tiny removable chips you can swap in and out of smartphones to get service. A SIM stores the information your phone needs to connect to your carrier network so you can send texts, make calls, and more. While many of today&rsquo;s phones and devices still rely on physical SIM cards for network connectivity, newer devices are increasingly turning to a newer technology called eSIM. &nbsp;

eSIM is short for Embedded SIM and is a digital version of a SIM card. eSIM allows you to connect to your network without having to deal with a physical chip. Instead of storing all information on a SIM card, you can download data to your device via the internet, activate your eSIM, and connect to your network in a completely virtual way.
