That setting only hide your number for phone calls. It has zero impact on SMS. When you send a text message, your phone number is still transmitted through your carrier\u2019s managing system.<\/li>\n\n\n\n<li><strong>iMessage Risk: <\/strong>Another misconception on iPhone is the belief that SMS are anonymous when sent through iMessage. The truth is that your <strong>Sender ID<\/strong> is linked to your <strong>Apple ID<\/strong>, which means you can still be identified.<\/li>\n\n\n\n<li><strong>Android Settings: <\/strong>Similar to iPhone, you cannot send anonymous SMS on Android when you use the #31# code. The <strong>Hide Number<\/strong> feature on your Samsung, Pixel, and other Android devices only apply to outgoing calls, not SMS.<\/li>\n<\/ul>\n\n\n\n<p>It\u2019s very risky if you rely on these settings for sending private texts. They practically create a false sense of security\u2014you think your identity is hidden, but it\u2019s otherwise.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Solution_Using_a_Web-Based_SMS_Gateway_AnonSMS\"><\/span>The Solution: Using a Web-Based SMS Gateway (AnonSMS)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>To be truly anonymous, you must bypass your SIM card entirely. As long as your mobile carrier is involved, you can be discovered. The perfect solution for anonymous texting in the Netherlands is to use a <strong>Web Gateway<\/strong> that\u2019s not associated in any way to your personal information. A reliable Web Gateway to use is AnonSMS\u2014a private texting tool.<\/p>\n\n\n\n<p>AnonSMS works by routing your text message through its own system. Instead of sending the message from your phone number, it uses the AnonSMS servers, ensuring that your message doesn\u2019t touch the carrier\u2019s network. This means that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Your real number is not exposed.<\/li>\n\n\n\n<li>Your IP address is stripped before delivery.<\/li>\n\n\n\n<li>The recipient cannot find out who you are, even when they contact their mobile carrier (be it KPN, Vodafone, Odido, or Simyo).<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step-by-Step_Guide_How_to_Send_Your_First_Message\"><\/span>Step-by-Step Guide: How to Send Your First Message<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Follow these steps to send anonymous SMS in the Netherlands without using the #31# text message code:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Step_1_Go_to_the_AnonSMS_Website\"><\/span>Step 1: Go to the AnonSMS Website<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Open your browser (it could be Safari, Chrome, or any browser) and go to <a href=\"https:\/\/www.anonsms.com\/nl\">anonsms.com<\/a>.
