This <strong>step-by-step tutorial<\/strong> will guide you through using the <strong>Send Group SMS feature<\/strong>, explaining each field and functionality to ensure you send messages successfully while avoiding common pitfalls.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Step-by-Step Guide<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Access the Send Group SMS Interface<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: Log in to your <strong>SMSGatewayCenter<\/strong> account and navigate to the <strong>Compose SMS<\/strong> menu, where you\u2019ll find the <strong><a href=\"https:\/\/www.smsgatewaycenter.com\">Group SMS<\/a><\/strong> option. Select this method to send messages to pre-defined groups of recipients.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t attempt to send messages without logging in, as unauthorized access will result in errors or blocked requests. Avoid using the Group SMS method if you need to send to individual numbers\u2014use the Quick SMS method instead.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-15.png\"><img loading=\"lazy\" decoding=\"async\" width=\"408\" height=\"418\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-15.png\" alt=\"Send Group SMS\" class=\"wp-image-1522\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-15.png 408w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-15-293x300.png 293w\" sizes=\"auto, (max-width: 408px) 100vw, 408px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">2. Verify the Send Type Field<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: Note that the <strong>Send Type<\/strong> field is preselected as \u201c<strong>Group<\/strong>\u201d and cannot be changed. This confirms you\u2019re using the Group Send method to target groups of recipients, not individual numbers or other send types.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t try to modify or override the \u201cGroup\u201d setting, as it\u2019s fixed for this method. Avoid confusion by ensuring your recipient data is organized into groups before proceeding.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Select a Sender ID<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: In the <strong>Sender ID<\/strong> field, select an approved sender ID from the dropdown list. This alphanumeric name or number will appear on recipients\u2019 phones, identifying you as the sender. Choose an appropriate sender ID based on your campaign needs. You can set a default sender ID in the <strong>Sender ID<\/strong> section of your account, which will automatically load on the compose page for convenience.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t use an unapproved or unrecognized sender ID, as this can lead to message rejections by operators. Avoid leaving this field blank or selecting a sender ID not registered for your account.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-3.png\"><img loading=\"lazy\" decoding=\"async\" width=\"794\" height=\"414\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-3.png\" alt=\"Select a Sender ID\" class=\"wp-image-1507\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-3.png 794w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-3-300x156.png 300w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-3-768x400.png 768w\" sizes=\"auto, (max-width: 794px) 100vw, 794px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">4. Select Single or Multiple Groups<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: Use the <strong>Select Single\/Multiple Group(s)<\/strong> field to choose the groups you want to send messages to. Click on each group name one by one to select multiple groups if needed. The interface will display the contact count for each selected group next to its name, and the total number of contacts across all selected groups will appear below the selection box. Ensure your groups are properly created and populated with valid mobile numbers in your <strong>SMSGatewayCenter<\/strong> account.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t select groups without verifying their contact lists, as invalid or duplicate numbers can cause delivery failures. Avoid selecting too many groups at once without checking total contact limits, which could exceed system or operator constraints.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-16.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"205\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-16-1024x205.png\" alt=\"Select Group\" class=\"wp-image-1523\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-16-1024x205.png 1024w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-16-300x60.png 300w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-16-768x153.png 768w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-16-1536x307.png 1536w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-16.png 1622w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">5. Choose the Message Type<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: Use the <strong>Message Type<\/strong> field to select your send method. The default options are:<\/li>\n\n\n\n<li><strong>Text<\/strong>: Send messages using the GSM 03.38 character set (standard Latin characters).<\/li>\n\n\n\n<li><strong>Unicode<\/strong>: Send messages using the Unicode character set for non-Latin characters (e.g., Hindi, Arabic).<\/li>\n\n\n\n<li>If you choose <strong>Unicode<\/strong>, type your message in English, press the spacebar, and select a language from the dropdown (e.g., Hindi) to transliterate the text automatically (e.g., \u201cNamaste\u201d becomes \u0928\u092e\u0938\u094d\u0924\u0947).<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t select <strong>Unicode<\/strong> unless you need non-Latin characters, as it can increase message costs. Avoid mixing Text and Unicode characters in the same message without understanding cost implications, as Unicode messages are priced higher.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-5.png\"><img loading=\"lazy\" decoding=\"async\" width=\"524\" height=\"334\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-5.png\" alt=\"Choose the Message Type\" class=\"wp-image-1509\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-5.png 524w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-5-300x191.png 300w\" sizes=\"auto, (max-width: 524px) 100vw, 524px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">6. Enable Smart Link (Optional)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: If you want to include a smart link, toggle the <strong>Enable Smart Link<\/strong> switch to \u201cOn.\u201d A <strong>Smart Link Title<\/strong> field will appear\u2014enter a title for the link. In the <strong>Text Message<\/strong> field (Step 8), click the \u201cSmart Link\u201d or \u201cMedia Link\u201d options to open a modal, where you can add a new link or select from previously saved links. The link will be appended to your message automatically.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t enable Smart Link unless your campaign requires interactive links, as unnecessary links can confuse recipients. Avoid using invalid or broken URLs, which could lead to delivery issues or user frustration.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-2.png\"><img loading=\"lazy\" decoding=\"async\" width=\"614\" height=\"360\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-2.png\" alt=\"Enable Smart Link \" class=\"wp-image-1506\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-2.png 614w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-2-300x176.png 300w\" sizes=\"auto, (max-width: 614px) 100vw, 614px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">7. Remove Duplicates (Optional)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: By default, the <strong>Remove Duplicates<\/strong> option is enabled, removing any duplicate numbers from your groups to prevent redundant sends. If you intentionally want to send messages to duplicate numbers, uncheck this option\u2014but proceed with caution, as some operators may block duplicate deliveries, leading to failures.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t uncheck this option without a specific reason, as sending to duplicate numbers can waste credits, increase costs, and result in delivery failures. Avoid entering lists with known duplicates without reviewing operator policies.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-7.png\"><img loading=\"lazy\" decoding=\"async\" width=\"370\" height=\"154\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-7.png\" alt=\"Remove Duplicates\" class=\"wp-image-1511\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-7.png 370w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-7-300x125.png 300w\" sizes=\"auto, (max-width: 370px) 100vw, 370px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">8. Send as Flash SMS (Optional)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: If you want the SMS to appear as a pop-up on the recipient\u2019s device, enable the <strong>Send as Flash SMS<\/strong> toggle. This is useful for urgent notifications but should be used sparingly.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t overuse Flash SMS, as recipients may find it intrusive, and some operators or devices may restrict or block it. Avoid using Flash SMS for non-urgent or promotional messages.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-8.png\"><img loading=\"lazy\" decoding=\"async\" width=\"262\" height=\"136\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-8.png\" alt=\"Send Flash SMS\" class=\"wp-image-1512\"\/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">9. Compose Your Text Message<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: Enter your message content in the <strong>Text Message<\/strong> field. You can send both Text and Unicode messages here, or combine them, but note that Unicode content may increase costs. Use the DLT Templates List (Step 10) or drafts (Step 12) to streamline message creation. Review the live preview in the right column to see how the message will appear on a mobile device, including the sender name, timestamp, and content.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t exceed character limits (160 for Text, 70 for Unicode per message part) without understanding how this affects costs or delivery (messages may be split into multiple parts). Avoid including sensitive or inappropriate content that could violate regulations or operator policies.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-9.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"312\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-9-1024x312.png\" alt=\"Compose Your Text Message\" class=\"wp-image-1513\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-9-1024x312.png 1024w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-9-300x91.png 300w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-9-768x234.png 768w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-9-1536x468.png 1536w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-9.png 1616w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">10. Select or Add a DLT Template<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: Use the <strong>DLT Templates List<\/strong> field to choose a pre-approved template based on your selected sender ID. The template will automatically populate in the <strong>Text Message<\/strong> field, and the associated <strong>DLT Template ID<\/strong> will be added to the <strong>DLT Template ID<\/strong> field. If you manually enter a template, ensure you also input the correct template ID in the <strong>DLT Template ID<\/strong> field to comply with regulatory requirements.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t use an unapproved or mismatched DLT template, as this can result in message rejection due to regulatory non-compliance (e.g., DLT in India). Avoid leaving the <strong>DLT Template ID<\/strong> field blank if manually adding a template.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-10.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"107\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-10-1024x107.png\" alt=\"Select or Add a DLT Template\" class=\"wp-image-1514\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-10-1024x107.png 1024w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-10-300x31.png 300w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-10-768x81.png 768w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-10-1536x161.png 1536w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-10.png 1620w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">11. Save as Draft (Optional)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What to Do<\/strong>: If you want to save your message for later use, enable the <strong>Save Message Content as Draft<\/strong> toggle. This saves the content in the <strong>Text Message<\/strong> field, allowing you to retrieve and append it later, which is helpful for recurring campaigns or unfinished messages.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t rely on drafts for sensitive or time-sensitive messages without securing them, as drafts are tied to your account and could be accidentally modified or deleted. Avoid overwriting existing drafts without confirming the content.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-11.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"96\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-11-1024x96.png\" alt=\"Save as Draft\" class=\"wp-image-1515\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-11-1024x96.png 1024w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-11-300x28.png 300w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-11-768x72.png 768w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-11-1536x144.png 1536w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-11.png 1616w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">12.

The message will be delivered at the specified time. You can later update or cancel the schedule via the <strong>Manage Schedule<\/strong> menu in your account.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t schedule messages without verifying the time zone (use your account\u2019s default time zone or specify UTC\/GMT explicitly). Avoid scheduling messages too far in advance without monitoring operator policies, as some may limit scheduling periods.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-12.png\"><img loading=\"lazy\" decoding=\"async\" width=\"804\" height=\"150\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-12.png\" alt=\"Schedule Message\" class=\"wp-image-1516\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-12.png 804w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-12-300x56.png 300w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-12-768x143.png 768w\" sizes=\"auto, (max-width: 804px) 100vw, 804px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">13.

This is useful for large groups to manage delivery rates and avoid operator throttling. Two additional fields will appear:<\/li>\n\n\n\n<li><strong>Campaign Limit<\/strong>: Enter the number of messages to send per batch (e.g., 10,000 out of 100,000 total contacts).<\/li>\n\n\n\n<li><strong>Time Interval<\/strong>: Select an interval from the dropdown (e.g., 1 hour) to space out batches, ensuring smooth delivery.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t set an unrealistically low or high Campaign Limit without testing, as this can overwhelm operators or delay delivery. Avoid choosing a Time Interval that\u2019s too short, which could trigger rate limits or delivery failures.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-17.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"192\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-17-1024x192.png\" alt=\"Enable Campaign Manager\" class=\"wp-image-1524\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-17-1024x192.png 1024w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-17-300x56.png 300w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-17-768x144.png 768w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-17-1536x288.png 1536w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-17.png 1608w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">14.

Enter your personal WhatsApp number (with the country code) in the <strong>WhatsApp Number<\/strong> field and optional default text in the <strong>WhatsApp Text<\/strong> field (e.g., \u201cHi ABC, please contact me\u201d). This generates a short link that, when clicked by recipients, opens WhatsApp to send a message to your number with the default text.<\/li>\n\n\n\n<li><strong>What Not to Do<\/strong>: Don\u2019t enable this feature unless your campaign targets WhatsApp users, as it may confuse SMS recipients. Avoid using invalid WhatsApp numbers or spam-like default text, which could violate WhatsApp policies or lead to rejections.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-13.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"100\" src=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-13-1024x100.png\" alt=\"Send WhatsApp Link\" class=\"wp-image-1517\" srcset=\"https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-13-1024x100.png 1024w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-13-300x29.png 300w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-13-768x75.png 768w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-13-1536x150.png 1536w, https:\/\/www.smsgatewaycenter.com\/blog\/wp-content\/uploads\/2025\/03\/image-13.png 1622w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">15.
