Which one should you buy for cost savings and strong 4G\/5G signal? Practical advice from airport experts.<\/p>\n<p data-path-to-node=\"13\">The choice between eSIM and physical SIM depends on your phone model and convenience needs. In Vietnam, eSIM (priced from 180,000 VND) is popular due to its instant online activation, while physical SIM (priced from 150,000 VND) remains a lifesaver for older phones or when you need a reliable physical connection. With the 4G\/5G infrastructure at Tan Son Nhat Airport, both offer stable, high speeds.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_74 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Index<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewbox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewbox=\"0 0 24 24\" version=\"1.2\" baseprofile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1' ><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/tansonnhatairport.vn\/en\/esim-hay-sim-vat-ly-du-lich-viet-nam.html\/#esim-du-lich-su-tien-loi-cua-ky-nguyen-so\" >eSIM for travel: The convenience of the digital age.<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/tansonnhatairport.vn\/en\/esim-hay-sim-vat-ly-du-lich-viet-nam.html\/#sim-vat-ly-lua-chon-truyen-thong-va-on-dinh\" >Physical SIM: A traditional and stable choice<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/tansonnhatairport.vn\/en\/esim-hay-sim-vat-ly-du-lich-viet-nam.html\/#so-sanh-chi-tiet-toc-do-gia-thanh-va-do-phu-song\" >Detailed comparison: Speed, cost, and coverage.<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/tansonnhatairport.vn\/en\/esim-hay-sim-vat-ly-du-lich-viet-nam.html\/#mua-sim-tai-san-bay-tan-son-nhat-luu-y-de-khong-bi-%e2%80%9cho%e2%80%9d\" >Buying a SIM card at Tan Son Nhat Airport: Things to note to avoid being ripped off.<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/tansonnhatairport.vn\/en\/esim-hay-sim-vat-ly-du-lich-viet-nam.html\/#cach-kiem-tra-dien-thoai-co-ho-tro-esim-hay-khong\" >How to check if your phone supports eSIM<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/tansonnhatairport.vn\/en\/esim-hay-sim-vat-ly-du-lich-viet-nam.html\/#huong-dan-cai-dat-va-kich-hoat-nhanh-trong-3-phut\" >Quick installation and activation guide in 3 minutes.<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/tansonnhatairport.vn\/en\/esim-hay-sim-vat-ly-du-lich-viet-nam.html\/#cau-hoi-thuong-gap-faq\" >Frequently Asked Questions (FAQ)<\/a><\/li><\/ul><\/nav><\/div>\n<h3 data-path-to-node=\"14\"><span class=\"ez-toc-section\" id=\"esim-du-lich-su-tien-loi-cua-ky-nguyen-so\"><\/span>eSIM for travel: The convenience of the digital age.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p data-path-to-node=\"15\"><b data-path-to-node=\"15\" data-index-in-node=\"0\"><a href=\"https:\/\/tansonnhatairport.vn\/\">Is eSIM better than a regular SIM?<\/a> When traveling in Vietnam?<\/b><\/p>\n<p data-path-to-node=\"15\">eSIM (Embedded SIM) is the top choice for modern travelers thanks to its ability to be purchased and activated entirely online without removing or inserting the SIM tray. In Vietnam, major carriers like Viettel and Vinaphone support eSIM with strong 4G\/5G signals, ensuring you have internet access as soon as you land at Tan Son Nhat Airport.<\/p>\n<p data-path-to-node=\"16\">Using an eSIM helps travelers avoid the risk of losing their main SIM card when removing and inserting it. In particular, you can purchase an eSIM through apps like Klook or Traveloka while still abroad, then simply scan the QR code at the airport to call a ride-hailing service (Grab\/Be) to your hotel immediately. In my experience, this is the most convenient solution for transit passengers or short-term travelers.<\/p>\n<figure id=\"attachment_11623\" aria-describedby=\"caption-attachment-11623\" style=\"width: 1020px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-11623 lazyload\" data-src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-1024x572.webp\" alt=\"\" width=\"1020\" height=\"570\" data-srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-1024x572.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-300x167.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-768x429.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-1536x857.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-2048x1143.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-600x335.webp 600w\" data-sizes=\"(max-width: 1020px) 100vw, 1020px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1020px; --smush-placeholder-aspect-ratio: 1020\/570;\" \/><noscript><img decoding=\"async\" class=\"size-large wp-image-11623\" src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-1024x572.webp\" alt=\"\" width=\"1020\" height=\"570\" srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-1024x572.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-300x167.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-768x429.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-1536x857.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-2048x1143.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h1-600x335.webp 600w\" sizes=\"(max-width: 1020px) 100vw, 1020px\" \/><\/noscript><figcaption id=\"caption-attachment-11623\" class=\"wp-caption-text\">Activate your Vietnam travel eSIM quickly upon landing at Tan Son Nhat International Airport.<\/figcaption><\/figure>\n<h3 data-path-to-node=\"18\"><span class=\"ez-toc-section\" id=\"sim-vat-ly-lua-chon-truyen-thong-va-on-dinh\"><\/span>Physical SIM: A traditional and stable choice<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p data-path-to-node=\"19\"><b data-path-to-node=\"19\" data-index-in-node=\"0\">When should you still choose to buy a traditional physical SIM card?<\/b><\/p>\n<p data-path-to-node=\"19\">Physical SIM cards remain popular thanks to their 100% compatibility with all current phone models, from older iPhones to mid-range Android phones. If your phone doesn&#039;t support eSIM technology, or you want a physical SIM card for easy switching to other phones in your group, a physical SIM card is an irreplaceable option.<\/p>\n<p data-path-to-node=\"20\">At the arrival area of Tan Son Nhat Airport, physical SIM card counters are always available. However, we &quot;insiders&quot; usually advise customers to pre-order online and pick up at the counter for a cheaper price (20-30%) compared to buying directly on-site. Physical SIM cards in Vietnam often come with &quot;powerful&quot; data packages such as 4GB\/day or unlimited data, very suitable for those who need to watch YouTube or livestream continuously.<\/p>\n<h3 data-path-to-node=\"21\"><span class=\"ez-toc-section\" id=\"so-sanh-chi-tiet-toc-do-gia-thanh-va-do-phu-song\"><\/span>Detailed comparison: Speed, cost, and coverage.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p data-path-to-node=\"22\">To help you decide, here&#039;s a practical comparison based on the most important criteria for a visitor arriving in Saigon:<\/p>\n<table data-path-to-node=\"23\">\n<thead>\n<tr>\n<td><strong>Criteria<\/strong><\/td>\n<td><strong>Travel eSIM<\/strong><\/td>\n<td><strong>Physical SIM<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"23,1,0,0\"><b data-path-to-node=\"23,1,0,0\" data-index-in-node=\"0\">Convenience<\/b><\/span><\/td>\n<td><span data-path-to-node=\"23,1,1,0\">Very high (Scan QR code)<\/span><\/td>\n<td><span data-path-to-node=\"23,1,2,0\">Average (Removing and inserting the SIM tray)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"23,2,0,0\"><b data-path-to-node=\"23,2,0,0\" data-index-in-node=\"0\">Cost<\/b><\/span><\/td>\n<td><span data-path-to-node=\"23,2,1,0\">180,000 VND \u2013 350,000 VND<\/span><\/td>\n<td><span data-path-to-node=\"23,2,2,0\">150,000 VND \u2013 300,000 VND<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"23,3,0,0\"><b data-path-to-node=\"23,3,0,0\" data-index-in-node=\"0\">Compatibility<\/b><\/span><\/td>\n<td><span data-path-to-node=\"23,3,1,0\">Only newer models (iPhone XR and later)<\/span><\/td>\n<td><span data-path-to-node=\"23,3,2,0\">All models<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"23,4,0,0\"><b data-path-to-node=\"23,4,0,0\" data-index-in-node=\"0\">Network speed<\/b><\/span><\/td>\n<td><span data-path-to-node=\"23,4,1,0\">4G\/5G stable<\/span><\/td>\n<td><span data-path-to-node=\"23,4,2,0\">4G\/5G stable<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"23,5,0,0\"><b data-path-to-node=\"23,5,0,0\" data-index-in-node=\"0\">Place to buy<\/b><\/span><\/td>\n<td><span data-path-to-node=\"23,5,1,0\">Online 24\/7<\/span><\/td>\n<td><span data-path-to-node=\"23,5,2,0\">Airport counter or shop<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"23,6,0,0\"><b data-path-to-node=\"23,6,0,0\" data-index-in-node=\"0\">Risk<\/b><\/span><\/td>\n<td><span data-path-to-node=\"23,6,1,0\">Forgot to save the QR code<\/span><\/td>\n<td><span data-path-to-node=\"23,6,2,0\">It&#039;s easy to lose your main SIM card.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<figure id=\"attachment_11624\" aria-describedby=\"caption-attachment-11624\" style=\"width: 1020px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-11624 lazyload\" data-src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h2-1024x765.webp\" alt=\"\" width=\"1020\" height=\"762\" data-srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h2-1024x765.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h2-300x224.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h2-768x573.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h2-1536x1147.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h2-2048x1529.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h2-16x12.webp 16w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/h2-600x448.webp 600w\" data-sizes=\"(max-width: 1020px) 100vw, 1020px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1020px;

A helpful tip is not to rush to buy at the first counter. Head towards the exit; the counters in the waiting area often have more promotions.<\/p>\n<p data-path-to-node=\"27\">One risk to avoid is the use of unregistered &quot;junk SIMs.&quot; For peace of mind, you should choose Viettel or Vinaphone plans. Especially if you arrive during peak hours (12 PM or 7 PM), queuing to buy a SIM in person will be very time-consuming. Booking through Klook and picking up at a clearly labeled service counter is the smartest way to save at least 30 minutes of waiting time.<\/p>\n<blockquote data-path-to-node=\"28\">\n<p data-path-to-node=\"28,0\"><b data-path-to-node=\"28,0\" data-index-in-node=\"0\">Top picks:<\/b><\/p>\n<ul data-path-to-node=\"28,1\">\n<li>\n<p data-path-to-node=\"28,1,0,0\"><b data-path-to-node=\"28,1,0,0\" data-index-in-node=\"0\">For customers who value convenience:<\/b> Buy an international eSIM on Klook \u2013 Receive your code via email in 5 minutes.
