What is eSIM and why should passengers at Tan Son Nhat airport use it immediately?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"14\">An eSIM is a digital SIM card integrated into the iPhone&#039;s circuit board, allowing you to activate mobile plans from Vietnamese carriers without needing a physical SIM card. At Tan Son Nhat Airport, using an eSIM helps passengers skip the wait at traditional SIM card counters and allows them to use both their home country phone number and their Vietnamese domestic number simultaneously on the same device.<\/p>\n<p data-path-to-node=\"15\">In reality, the International Arrivals area is often very crowded during nighttime hours (10 PM - 1 AM). Having an eSIM QR code sent to your email before your flight will give you complete control. I&#039;ve witnessed many tourists struggling to find a SIM card shop after landing, when all they had to do was turn on their phone, scan the code, and they&#039;d have 5G to call a taxi to District 1.<\/p>\n<figure id=\"attachment_11670\" aria-describedby=\"caption-attachment-11670\" style=\"width: 1020px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-11670 lazyload\" data-src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-1024x559.webp\" width=\"1020\" height=\"557\" data-srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-600x327.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\/557;\" \/><noscript><img decoding=\"async\" class=\"size-large wp-image-11670\" src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-1024x559.webp\" width=\"1020\" height=\"557\" srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-600x327.webp 600w\" sizes=\"(max-width: 1020px) 100vw, 1020px\" \/><\/noscript><figcaption id=\"caption-attachment-11670\" class=\"wp-caption-text\">Scan the QR code at Tan Son Nhat International Airport&#039;s arrival hall to activate your iPhone eSIM and enjoy high-speed 5G in just 2 minutes.<\/figcaption><\/figure>\n<h2 data-path-to-node=\"17\"><span class=\"ez-toc-section\" id=\"2-dieu-kien-can-de-iphone-cua-ban-tuong-thich-voi-esim-viet-nam\"><\/span>2. Requirements for your iPhone to be compatible with Vietnamese eSIM<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"18\">To successfully install eSIM in Vietnam, you need an iPhone from the XS, XS Max, XR series or later (running iOS 12.1 or later) and the device must be an international version (not network locked). In Vietnam, all four major carriers \u2013 Viettel, Vinaphone, Mobifone, and Wintel \u2013 fully support eSIM with stable 4G\/5G speeds around the airport area.<\/p>\n<p data-path-to-node=\"19\">As &quot;insiders,&quot; we often advise customers: If you buy an iPhone imported from the US (iPhone 14 and later models), the device will not have a physical SIM slot; you must use an eSIM 100%. Before scanning the code, make sure your iPhone is connected to the airport&#039;s free Wi-Fi (&quot;Airport Free Wi-Fi&quot;) or the Wi-Fi in business lounges to ensure the authentication process with Apple&#039;s servers is not interrupted.<\/p>\n<h2 data-path-to-node=\"20\"><span class=\"ez-toc-section\" id=\"3-mua-esim-o-dau-tai-ga-quoc-te-va-ga-quoc-noi-tan-son-nhat\"><\/span>3. Where can I buy an eSIM at Tan Son Nhat International and Domestic Terminals?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"21\">You can purchase eSIMs directly at telecommunications service counters in the International Terminal arrival hall (located behind the customs screening area) or Hall A of the Domestic Terminal. The price of a short-term travel eSIM package ranges from VND 150,000 to VND 350,000 depending on data capacity. However, the best way is still to order online through apps like Klook, Airalo, or directly on the carrier&#039;s website to receive a QR code via email. The process of setting up an eSIM on a Vietnamese iPhone after receiving the QR code only takes 2-3 minutes.<\/p>\n<p data-path-to-node=\"22\">If you land at the domestic terminal, go to the counters near exits A1 and A2. A tip for business travelers: Don&#039;t buy SIM cards from counters without clearly displayed prices. Choose official Viettel or Vinaphone dealers to get assistance with registering the SIM card in your name using your passport\/citizen identification card on the spot, ensuring the SIM card won&#039;t be blocked after a few days of use.<\/p>\n<h2 data-path-to-node=\"23\"><span class=\"ez-toc-section\" id=\"4-huong-dan-cac-buoc-quet-ma-qr-cai-dat-esim-tren-iphone-chi-tiet\"><\/span>4. Detailed instructions on how to scan the QR code to set up eSIM on iPhone.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"24\">To install, go to <b data-path-to-node=\"24\" data-index-in-node=\"20\">Settings<\/b> news <b data-path-to-node=\"24\" data-index-in-node=\"41\">Cellular<\/b> news <b data-path-to-node=\"24\" data-index-in-node=\"62\">Add eSIM<\/b>Now, please choose <b data-path-to-node=\"24\" data-index-in-node=\"102\">Use QR Code<\/b> Point your camera at the QR code image provided by your carrier. It will take your iPhone approximately 30-60 seconds to &quot;Activate&quot; and display the message &quot;Mobile plan added&quot;.<\/p>\n<p data-path-to-node=\"25\">After the scan is complete, the system will ask you to name your SIM label. I recommend naming it &quot;Vietnam&quot; or &quot;Tourism&quot; to distinguish it from your main home SIM. During this process, if your iPhone displays &quot;Unable to complete activation,&quot; try turning it off and restarting it, or check if you are in an area with very weak signal (such as in a TCP parking garage).<\/p>\n<figure id=\"attachment_11671\" aria-describedby=\"caption-attachment-11671\" style=\"width: 1020px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-11671 lazyload\" data-src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-1024x559.webp\" alt=\"Infographic h\u01b0\u1edbng d\u1eabn 3 b\u01b0\u1edbc c\u00e0i \u0111\u1eb7t eSIM tr\u00ean iPhone t\u1ea1i Vi\u1ec7t Nam: Qu\u00e9t m\u00e3 QR, K\u00edch ho\u1ea1t g\u00f3i c\u01b0\u1edbc v\u00e0 K\u1ebft n\u1ed1i 4G\/5G.\" width=\"1020\" height=\"557\" data-srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-600x327.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\/557;\" \/><noscript><img decoding=\"async\" class=\"size-large wp-image-11671\" src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-1024x559.webp\" alt=\"Infographic h\u01b0\u1edbng d\u1eabn 3 b\u01b0\u1edbc c\u00e0i \u0111\u1eb7t eSIM tr\u00ean iPhone t\u1ea1i Vi\u1ec7t Nam: Qu\u00e9t m\u00e3 QR, K\u00edch ho\u1ea1t g\u00f3i c\u01b0\u1edbc v\u00e0 K\u1ebft n\u1ed1i 4G\/5G.\" width=\"1020\" height=\"557\" srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-600x327.webp 600w\" sizes=\"(max-width: 1020px) 100vw, 1020px\" \/><\/noscript><figcaption id=\"caption-attachment-11671\" class=\"wp-caption-text\">Here&#039;s a summary of the quick 3-step eSIM setup process on iPhones for passengers at Tan Son Nhat Airport.<\/figcaption><\/figure>\n<h2 data-path-to-node=\"27\"><span class=\"ez-toc-section\" id=\"5-cach-thiet-lap-esim-lam-dong-du-lieu-chinh-de-tranh-phi-roaming\"><\/span>5. How to set up eSIM as your primary data stream to avoid roaming charges.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"28\">After completing the process of installing eSIM on a Vietnamese iPhone, the most important step is to designate the newly installed eSIM as your cellular data source. You can do this by going to... <b data-path-to-node=\"28\" data-index-in-node=\"134\">Setting<\/b> news <b data-path-to-node=\"28\" data-index-in-node=\"144\">Mobile<\/b> news <b data-path-to-node=\"28\" data-index-in-node=\"154\">Mobile data<\/b>Then, select the new eSIM option. At the same time, turn off the &quot;Allow Cellular Data Switching&quot; feature so that your iPhone doesn&#039;t automatically use data from your primary SIM when the eSIM signal is weak.<\/p>\n<p data-path-to-node=\"29\">This is extremely important because if you don&#039;t set it up properly, your iPhone could still use a foreign SIM card to access the internet, leading to roaming bills of thousands of dollars overnight. While waiting for your luggage at the conveyor belt, take 30 seconds to double-check this, making sure the &quot;Vietnam&quot; text is displayed in the signal strength indicator at the top of the screen.<\/p>\n<h2 data-path-to-node=\"30\"><span class=\"ez-toc-section\" id=\"6-xu-ly-loi-thuong-gap-tai-sao-iphone-khong-nhan-ma-qr-esim\"><\/span>6. Troubleshooting common issues: Why isn&#039;t my iPhone recognizing the eSIM QR code?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"31\">The most common errors are that the QR code has expired or has already been scanned by another device. Additionally, if your iPhone is locked and fixed with an ICCID code, it will reject any additional eSIMs. Another possibility is an unstable airport Wi-Fi connection preventing the device from connecting to Apple&#039;s activation server.<\/p>\n<p data-path-to-node=\"32\">If you encounter an error, don&#039;t try scanning it more than 5 times as the QR code may be locked. Move to a more open area (near the entrance to the reception area) for better signal reception or ask the SIM counter staff to check your plan status on the system. Sometimes, simply updating to the latest iOS version will resolve the issue.<\/p>\n<h2 data-path-to-node=\"33\"><span class=\"ez-toc-section\" id=\"7-meo-toi-uu-song-4g5g-khi-di-chuyen-tu-san-bay-ve-trung-tam\"><\/span>7.

If you see &quot;LTE&quot; instead of &quot;5G,&quot; you can turn Airplane Mode on and off so your iPhone can find the nearest cell tower.<\/p>\n<figure id=\"attachment_11672\" aria-describedby=\"caption-attachment-11672\" style=\"width: 1020px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-11672 lazyload\" data-src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-1024x559.webp\" alt=\"Kh\u00e1ch du l\u1ecbch s\u1eed d\u1ee5ng iPhone \u0111\u00e3 k\u00edch ho\u1ea1t eSIM th\u00e0nh c\u00f4ng t\u1ea1i qu\u00e1n Star Cafe s\u00e2n bay T\u00e2n S\u01a1n Nh\u1ea5t trong \u00e1nh ho\u00e0ng h\u00f4n.\" width=\"1020\" height=\"557\" data-srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-600x327.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\/557;\" \/><noscript><img decoding=\"async\" class=\"size-large wp-image-11672\" src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-1024x559.webp\" alt=\"Kh\u00e1ch du l\u1ecbch s\u1eed d\u1ee5ng iPhone \u0111\u00e3 k\u00edch ho\u1ea1t eSIM th\u00e0nh c\u00f4ng t\u1ea1i qu\u00e1n Star Cafe s\u00e2n bay T\u00e2n S\u01a1n Nh\u1ea5t trong \u00e1nh ho\u00e0ng h\u00f4n.\" width=\"1020\" height=\"557\" srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-600x327.webp 600w\" sizes=\"(max-width: 1020px) 100vw, 1020px\" \/><\/noscript><figcaption id=\"caption-attachment-11672\" class=\"wp-caption-text\">It&#039;s a reassuring feeling to see the &quot;Mobile plan updated&quot; notification while sipping coffee and waiting for your luggage.<\/figcaption><\/figure>\n<h2 data-path-to-node=\"37\"><span class=\"ez-toc-section\" id=\"8-so-sanh-cac-goi-cuoc-esim-du-lich-pho-bien-nhat-hien-nay\"><\/span>8.

Older models allowed you to store multiple eSIMs but only enabled one at a time along with one physical SIM.<\/span><\/p>\n<p data-path-to-node=\"41,1,0\"><b data-path-to-node=\"41,1,0\" data-index-in-node=\"0\">2.

If you accidentally select &quot;Cancel mobile plan,&quot; you must contact your mobile carrier to obtain a new code (this may incur a fee).<\/p>\n<p data-path-to-node=\"41,2,0\"><b data-path-to-node=\"41,2,0\" data-index-in-node=\"0\">3.

After installation, the internet on your device will work normally, and you won&#039;t need to set up the application account again.<\/p>\n<p data-path-to-node=\"41,3,0\"><b data-path-to-node=\"41,3,0\" data-index-in-node=\"0\">4.

Some travel plans require this setting to be enabled in order to access the internet in Vietnam.<\/p>\n<p data-path-to-node=\"41,4,0\"><b data-path-to-node=\"41,4,0\" data-index-in-node=\"0\">5.
