They are a popular option for receive SMS online and testing, while protecting personal data across apps like WhatsApp, Telegram, or banking apps.<\/li>    <li>eSIM allows multiple profiles on a single device, enabling easy switching between numbers without a physical card. This is useful for travelers or developers testing API integrations and OTP flows.<\/li>    <li>A second SIM keeps a separate line for personal and work use, ensuring physical separation and reliable connectivity for calls, texts, and data on devices with dual-SIM support.<\/li>  <\/ul>  <h2>How to get started<\/h2>  <ol>    <li>Disposable number: Visit SMSPVA\u2019s guide or service page to request a disposable number.

Set the new profile as active for the desired line.<\/li>    <li>Second SIM: Insert the additional SIM, configure network settings, assign default lanes for calls\/texts, and monitor data usage to manage costs.<\/li>  <\/ol>  <h2>Troubleshooting table<\/h2>  <div class=\"table-wrap\">    <table>      <thead>        <tr>          <th>Topic<\/th>          <th>Solution<\/th>        <\/tr>      <\/thead>      <tbody>        <tr>          <td>OTP not received<\/td>          <td>Ensure the number is active, request a new disposable number if needed, and verify that the message isn\u2019t blocked by the app.<\/td>        <\/tr>        <tr>          <td>No service with eSIM<\/td>          <td>Confirm carrier support for eSIM on the device, re-scan or re-activate the profile, and check roaming settings if traveling.<\/td>        <\/tr>        <tr>          <td>Calls or texts fail on 2nd SIM<\/td>          <td>Check SIM slot and network settings, ensure the correct default line is selected, and verify roaming\/data plans.<\/td>        <\/tr>      <\/tbody>    <\/table>  <\/div>  <h2>Safe and legal use<\/h2>  <p>Use disposable numbers, eSIM, or a second SIM for legitimate verification, privacy, and testing.
