Middle: the reseller route with an extra hop. Right: the route that triggers the emails and gets blocked.<\/figcaption><\/figure>\n<p>Here is what has been happening behind many SMS panels in India. You, the Principal Entity, created a PE-TM chain naming your provider as the telemarketer, call it <strong>TMD1<\/strong>. On paper TMD1 is a delivery telemarketer. In practice TMD1 does not hold its own connectivity with every operator; to reach Jio or Airtel it hands your messages to <strong>TMD2<\/strong>, a bigger telemarketer that does. The operator sees traffic for your PE arriving over TMD2&#8217;s connection, looks up your approved chain, finds TMD1, and flags a mismatch. That is the email.<\/p>\n<p>Under the old regime this borrowing was tolerated. Under the PE-TM Binding Framework it is not:<\/p>\n<ul>\n<li><strong>Every TMD must hold its own direct connectivity<\/strong> from each operator it delivers to.<\/li>\n<li><strong>One TMD cannot send traffic through another TMD&#8217;s connectivity.<\/strong> The chain must terminate at the telemarketer that physically hands the SMS to the network.<\/li>\n<li>Every message is checked for three things: the approved chain, the authorized TM-D, and the hash code that fingerprints that chain. Background: <a href=\"https:\/\/www.fast2sms.com\/help\/dlt-hash-code-pe-tm-chain\/\">DLT hash code explained<\/a>.<\/li>\n<li>From 30th September, anything that fails the check is <strong>summarily blocked<\/strong>, OTPs included.<\/li>\n<\/ul>\n<h2>Why the email comes to you and not to your vendor<\/h2>\n<p>DLT holds the Principal Entity responsible for its own traffic. Your PE ID is on every message, the chain is created and approved from your login, and only you can create a new chain to a different TMD. So the operator writes to the entity that can act, and tells you to &#8220;check with your Telemarketer for corrective action&#8221;. Your vendor may already know; some have been quietly hoping the enforcement date would move.<\/p>\n<h2>The part nobody mentions: copies of your data<\/h2>\n<p>When traffic travels PE \u2192 TMA \u2192 TMD1 \u2192 TMD2 \u2192 operator, each hop is a separate company handling your message content and your customers&#8217; mobile numbers. OTPs, order values, account alerts: <strong>a copy sits at every level<\/strong>. Direct connectivity is not only a compliance question; it is the difference between one party seeing your customer data and three.<\/p>\n<h2>Find out which route you are actually on<\/h2>\n<ol>\n<li>Open the operator email and note the <strong>flagged TMD ID<\/strong>.<\/li>\n<li>Log in to that operator&#8217;s DLT portal and open your PE-TM chain: note the <strong>TMD in your approved chain<\/strong> (if a chain exists at all; status guide: <a href=\"https:\/\/www.fast2sms.com\/help\/pe-tm-chain-status\/\">PE-TM chain status explained<\/a>).<\/li>\n<li>Ask your vendor for their <strong>TMD ID<\/strong> and whether they hold direct connectivity with that operator.<\/li>\n<\/ol>\n<p>If the flagged ID differs from the TMD in your chain, your traffic is riding someone else&#8217;s connectivity: exactly the blocked pattern. If the three IDs match and you are still flagged, the chain is probably not approved on that operator; see <a href=\"https:\/\/www.fast2sms.com\/help\/pe-tm-chain-mismatch-causes-fixes\/\">the seven mismatch causes<\/a>.<\/p>\n<h2>Your two options before the deadline<\/h2>\n<h3>Option A: Make your current vendor deliver on their own connectivity<\/h3>\n<p>Ask them to submit your traffic only through their own TMD connectivity on every operator, and to prove it with their TMD ID. Many resellers and small telemarketers cannot, because they never had direct operator links; that is why they borrowed them. If the answer is a delay or a new &#8220;partner&#8221;, assume the emails will continue.<\/p>\n<h3>Option B: Bind to a TMD that already has direct connectivity everywhere<\/h3>\n<div style=\"background:#ecfdf5;border:1px solid #a7f3d0;border-left:6px solid #059669;border-radius:8px;padding:20px 24px;margin:28px 0;\">\n<p style=\"margin:0 0 6px;font-size:16px;\"><strong>Fast2SMS registered TMD:<\/strong> SID GROUPS PRIVATE LIMITED &middot; TMD ID <strong>1702178720558766591<\/strong><\/p>\n<p style=\"margin:0;font-size:15px;\">Direct connectivity with <strong>Airtel, Jio, BSNL, Tata, Vi and Smartping<\/strong>.

Each DLT platform checks independently and each flags the mismatch on its own network.<\/p>\n<h3>What does &#8220;one TMD sending traffic from another TMD&#8221; mean?<\/h3>\n<p>The telemarketer in your chain (TMD1) does not have its own operator connectivity, so it delivers your SMS through a second telemarketer&#8217;s connection (TMD2). The operator sees TMD2, your chain says TMD1, mismatch.<\/p>\n<h3>Is this a problem with my templates, headers or entity registration?<\/h3>\n<p>No. Those stay valid. The problem is the delivery route versus the approved chain. Re-approving templates will not stop the emails.<\/p>\n<h3>My vendor says they are a TMD. Why the mismatch then?<\/h3>\n<p>Being registered as a TMD is not the same as holding direct connectivity with every operator. Ask which operators they connect to directly and whether your traffic ever passes through another TMD.<\/p>\n<h3>Will my SMS actually stop after 30th September?<\/h3>\n<p>Yes, on any route that mismatches: the operator drops the messages at handover, OTPs and transactional alerts included, with no per-message appeal.<\/p>\n<h3>Why do Fast2SMS users not receive these emails?<\/h3>\n<p>Fast2SMS (SID GROUPS PRIVATE LIMITED, TMD ID 1702178720558766591) holds direct connectivity with Airtel, Jio, BSNL, Tata, Vi and Smartping and never routes through another TMD, so the approved chain and the actual route are the same and the check passes.<\/p>\n<h3>Do I need to re-register on DLT to switch?<\/h3>\n<p>No. Your entity, headers and templates belong to your PE. You add a new PE-TM chain to the new TMD on each operator and point your sending at the new panel or API.<\/p>\n<h3>How long does the switch take?<\/h3>\n<p>Usually a day: chain requests take minutes per portal, Fast2SMS accepts promptly, and you complete the PE-side approval. Support does it with you on a free call.<\/p>\n<h3>What about the copies of my data at other TMDs?<\/h3>\n<p>Moving to a direct route stops new copies immediately; only one party, the delivery telemarketer, handles your traffic from then on.<\/p>\n<h3>Does this affect WhatsApp or RCS?<\/h3>\n<p>No. The framework applies to DLT SMS. Many businesses use <a href=\"https:\/\/www.fast2sms.com\/help\/otp-sms-smart-otp\/\">Smart OTP<\/a> on WhatsApp with SMS fallback as a safety net during migration.<\/p>\n<h3>Where do I get help?<\/h3>\n<p>Free meeting: <a href=\"https:\/\/www.fast2sms.com\/meet\" target=\"_blank\" rel=\"noopener\">fast2sms.com\/meet<\/a>.
