Why is eSIM a crucial option at Tan Son Nhat Airport in 2026?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"20\">eSIM has become an indispensable connectivity standard for travelers arriving at Tan Son Nhat Airport (TSN). Instead of fumbling for a SIM ejector tool or worrying about losing your main SIM card while traveling between countries, eSIM allows you to integrate multiple phone numbers on a single device in a convenient way.<br \/>\nSee also:<a href=\"https:\/\/ykhoa.ai\/\" target=\"_blank\" rel=\"noopener\">https:\/\/ykhoa.ai\/<\/a><\/p>\n<p data-path-to-node=\"21\">With 5G technology expected to fully cover Tan Binh and Phu Nhuan districts by 2026, an eSIM not only provides data but also acts as a &quot;ticket&quot; to book Grab, view real-time maps, and check into hotels instantly. Frequent transit passengers at Tan Son Nhat Airport highly appreciate this convenience, as it completely eliminates the need to queue at physical SIM card counters, which are always crowded during peak hours from 10:00 AM to 2:00 PM.<\/p>\n<figure id=\"attachment_11707\" aria-describedby=\"caption-attachment-11707\" style=\"width: 1020px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-11707 lazyload\" data-src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-1024x559.webp\" alt=\"M\u1ed9t h\u00e0nh kh\u00e1ch nam tr\u1ebb tu\u1ed5i \u0111\u1ee9ng t\u1ea1i nh\u00e0 ga S\u00e2n bay Qu\u1ed1c t\u1ebf T\u00e2n S\u01a1n Nh\u1ea5t, c\u1ea7m \u0111i\u1ec7n tho\u1ea1i th\u00f4ng minh hi\u1ec3n th\u1ecb m\u00e3 QR \u0111\u1ec3 k\u00edch ho\u1ea1t eSIM du l\u1ecbch, ph\u00eda sau l\u00e0 b\u1ea3ng th\u00f4ng tin chuy\u1ebfn bay l\u1edbn v\u00e0 ki\u1ebfn tr\u00fac hi\u1ec7n \u0111\u1ea1i.\" width=\"1020\" height=\"557\" data-srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-600x327.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-11707\" src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-1024x559.webp\" alt=\"M\u1ed9t h\u00e0nh kh\u00e1ch nam tr\u1ebb tu\u1ed5i \u0111\u1ee9ng t\u1ea1i nh\u00e0 ga S\u00e2n bay Qu\u1ed1c t\u1ebf T\u00e2n S\u01a1n Nh\u1ea5t, c\u1ea7m \u0111i\u1ec7n tho\u1ea1i th\u00f4ng minh hi\u1ec3n th\u1ecb m\u00e3 QR \u0111\u1ec3 k\u00edch ho\u1ea1t eSIM du l\u1ecbch, ph\u00eda sau l\u00e0 b\u1ea3ng th\u00f4ng tin chuy\u1ebfn bay l\u1edbn v\u00e0 ki\u1ebfn tr\u00fac hi\u1ec7n \u0111\u1ea1i.\" width=\"1020\" height=\"557\" srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-1-5-600x327.webp 600w\" sizes=\"(max-width: 1020px) 100vw, 1020px\" \/><\/noscript><figcaption id=\"caption-attachment-11707\" class=\"wp-caption-text\">Passengers can easily activate high-speed 5G eSIM upon landing at Tan Son Nhat International Airport.<\/figcaption><\/figure>\n<h2 data-path-to-node=\"23\"><span class=\"ez-toc-section\" id=\"2-bang-gia-cac-goi-esim-5g-pho-bien-nhat-cho-khach-du-lich\"><\/span>2. Price list of the most popular 5G eSIM packages for tourists<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"24\">eSIM pricing in Vietnam in 2026 has become much more competitive compared to previous years, especially for packages designed for short-term tourists. Currently, there are three main price segments that you can easily find at reputable dealers around the airport area.<\/p>\n<p data-path-to-node=\"25\">Basic packages typically range from 99,000 VND to 150,000 VND, providing approximately 2GB-5GB of high-speed data per day. Higher-end packages, starting from 300,000 VND, include unlimited calls and data, suitable for those who need to work online continuously or livestream. Locals often recommend purchasing long-term &quot;Tourist eSIM&quot; packages (15-30 days) for those planning a cross-Vietnam trip, as the daily cost is significantly cheaper.<\/p>\n<table data-path-to-node=\"26\">\n<thead>\n<tr>\n<td><strong>Type of plan<\/strong><\/td>\n<td><strong>Data capacity<\/strong><\/td>\n<td><strong>Duration<\/strong><\/td>\n<td><strong>Reference price (VN\u0110)<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"26,1,0,0\"><b data-path-to-node=\"26,1,0,0\" data-index-in-node=\"0\">eSIM Basic<\/b><\/span><\/td>\n<td><span data-path-to-node=\"26,1,1,0\">2GB\/day<\/span><\/td>\n<td><span data-path-to-node=\"26,1,2,0\">7 Days<\/span><\/td>\n<td><span data-path-to-node=\"26,1,3,0\">99.000<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"26,2,0,0\"><b data-path-to-node=\"26,2,0,0\" data-index-in-node=\"0\">eSIM Pro 5G<\/b><\/span><\/td>\n<td><span data-path-to-node=\"26,2,1,0\">5GB\/day<\/span><\/td>\n<td><span data-path-to-node=\"26,2,2,0\">10 Days<\/span><\/td>\n<td><span data-path-to-node=\"26,2,3,0\">199.000<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"26,3,0,0\"><b data-path-to-node=\"26,3,0,0\" data-index-in-node=\"0\">eSIM Unlimited<\/b><\/span><\/td>\n<td><span data-path-to-node=\"26,3,1,0\">Unlimited<\/span><\/td>\n<td><span data-path-to-node=\"26,3,2,0\">30 Days<\/span><\/td>\n<td><span data-path-to-node=\"26,3,3,0\">450.000<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 data-path-to-node=\"27\"><span class=\"ez-toc-section\" id=\"3-mua-esim-online-vs-mua-truc-tiep-tai-quay-dau-la-lua-chon-toi-uu\"><\/span>3. Buying eSIM online vs. Buying directly at the counter: Which is the best option?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"28\">Deciding whether to buy an eSIM online before flying or wait until landing at Tan Son Nhat (TSN) is a question many travelers are concerned about. Buying online allows you to receive the QR code immediately via email, proactively set it up beforehand, and have internet access as soon as the plane taxis to the parking area.<\/p>\n<p data-path-to-node=\"29\">However, buying directly at the counter in the International Terminal (T2) offers the advantage of technical support. If your phone experiences eSIM recognition errors, counter staff will handle it on the spot. However, prices at the counter are usually higher, ranging from 20-30%, due to expensive airport overhead costs. The advice from &quot;insiders&quot; is to buy online through reputable apps or official websites to get the best prices, keeping the counter purchase option as a backup in case of emergencies.<\/p>\n<figure id=\"attachment_11708\" aria-describedby=\"caption-attachment-11708\" style=\"width: 1020px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-11708 lazyload\" data-src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-1024x559.webp\" alt=\"Infographic so s\u00e1nh SIM v\u1eadt l\u00fd v\u00e0 eSIM t\u1ea1i s\u00e2n bay T\u00e2n S\u01a1n Nh\u1ea5t 2026. eSIM \u01b0u vi\u1ec7t h\u01a1n v\u1edbi kh\u1ea3 n\u0103ng k\u00edch ho\u1ea1t nhanh qua m\u00e3 QR, kh\u00f4ng t\u1ea1o r\u00e1c th\u1ea3i nh\u1ef1a b\u1ea3o v\u1ec7 m\u00f4i tr\u01b0\u1eddng, v\u00e0 m\u1ee9c gi\u00e1 r\u1ebb c\u1ea1nh tranh h\u01a1n so v\u1edbi SIM v\u1eadt l\u00fd truy\u1ec1n th\u1ed1ng ph\u1ea3i x\u1ebfp h\u00e0ng mua t\u1ea1i qu\u1ea7y.\" width=\"1020\" height=\"557\" data-srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-600x327.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-11708\" src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-1024x559.webp\" alt=\"Infographic so s\u00e1nh SIM v\u1eadt l\u00fd v\u00e0 eSIM t\u1ea1i s\u00e2n bay T\u00e2n S\u01a1n Nh\u1ea5t 2026. eSIM \u01b0u vi\u1ec7t h\u01a1n v\u1edbi kh\u1ea3 n\u0103ng k\u00edch ho\u1ea1t nhanh qua m\u00e3 QR, kh\u00f4ng t\u1ea1o r\u00e1c th\u1ea3i nh\u1ef1a b\u1ea3o v\u1ec7 m\u00f4i tr\u01b0\u1eddng, v\u00e0 m\u1ee9c gi\u00e1 r\u1ebb c\u1ea1nh tranh h\u01a1n so v\u1edbi SIM v\u1eadt l\u00fd truy\u1ec1n th\u1ed1ng ph\u1ea3i x\u1ebfp h\u00e0ng mua t\u1ea1i qu\u1ea7y.\" width=\"1020\" height=\"557\" srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-2-5-600x327.webp 600w\" sizes=\"(max-width: 1020px) 100vw, 1020px\" \/><\/noscript><figcaption id=\"caption-attachment-11708\" class=\"wp-caption-text\">eSIM offers superior speed, price, and sustainability compared to traditional physical SIM cards at Tan Son Nhat airport.<\/figcaption><\/figure>\n<h2 data-path-to-node=\"31\"><span class=\"ez-toc-section\" id=\"4-top-3-nha-mang-cung-cap-esim-5g-manh-nhat-khu-vuc-san-bay\"><\/span>4. Top 3 carriers offering the strongest 5G eSIM in airport areas.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"32\">By 2026, the network infrastructure at Tan Son Nhat Airport will be extremely modern, but the stability of service among network providers will still vary significantly. Viettel will maintain its leading position with the densest 5G coverage, especially in enclosed areas such as parking garages and the upper floors of the terminal.<\/p>\n<p data-path-to-node=\"33\">Vinaphone and MobiFone are also competitive with flexible packages specifically designed for young people and tourists. In particular, Vinaphone often has programs in partnership with travel apps, allowing users to receive free eSIMs or significant discounts when booking hotels. If you frequently travel to suburban areas or provinces after leaving Tan Son Nhat Airport, Viettel is the safest choice in terms of signal strength.<\/p>\n<h2 data-path-to-node=\"34\"><span class=\"ez-toc-section\" id=\"5-quy-trinh-kich-hoat-esim-sieu-toc-chi-trong-2-phut\"><\/span>5. Super-fast eSIM activation process in just 2 minutes.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"35\">Many people are still hesitant about the complexity of this technology, but in reality, the eSIM activation process in 2026 has been simplified to the maximum. You no longer need to compose cumbersome registration messages or fill out information through many steps as before.<\/p>\n<p data-path-to-node=\"36\">After receiving the QR code, simply go to the section <i data-path-to-node=\"36\" data-index-in-node=\"40\">Settings -&gt; Cellular -&gt; Add eSIM<\/i> Scan the code. The system will automatically identify your carrier and activate the plan within 30-60 seconds. A helpful tip: take a screenshot of the QR code or print it out, as you can&#039;t use your phone to open the QR code image. If you&#039;re traveling alone, you can borrow a tablet or use the free Wi-Fi at the airport (TSN Free Wi-Fi) to open the email containing the code.<\/p>\n<h2 data-path-to-node=\"37\"><span class=\"ez-toc-section\" id=\"6-nhung-%e2%80%9ccam-bay%e2%80%9d-can-tranh-khi-mua-simesim-tai-sanh-den-quoc-te\"><\/span>6. Pitfalls to avoid when buying SIM\/eSIM at international arrival halls.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"38\">The arrival hall at Tan Son Nhat International Airport is always bustling, but it also poses potential pricing risks for inexperienced travelers. Some SIM card vendors, without publicly displayed prices, often overcharge by price, quoting rates two to three times higher than the actual value of the package.<\/p>\n<p data-path-to-node=\"39\">Furthermore, be wary of offers like &quot;unlimited SIMs&quot; that only provide a few GB of high-speed data, then throttle the bandwidth to a level unusable for maps. I&#039;ve witnessed many tourists buying these &quot;junk&quot; SIMs that only work for 1-2 days before being blocked because they weren&#039;t registered with their personal information. The best approach is to always request a receipt and check your data usage on the spot using the network provider&#039;s check syntax before leaving the counter.<\/p>\n<figure id=\"attachment_11709\" aria-describedby=\"caption-attachment-11709\" style=\"width: 1020px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-large wp-image-11709 lazyload\" data-src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-1024x559.webp\" alt=\"C\u1eadn c\u1ea3nh b\u00e0n tay du kh\u00e1ch c\u1ea7m \u0111i\u1ec7n tho\u1ea1i iPhone hi\u1ec3n th\u1ecb th\u00f4ng b\u00e1o &quot;K\u00cdCH HO\u1ea0T TH\u00c0NH C\u00d4NG eSIM&quot; v\u1edbi d\u1ea5u t\u00edch xanh, ng\u1ed3i t\u1ea1i qu\u00e1n c\u00e0 ph\u00ea s\u1ea3nh Ga \u0111\u1ebfn Qu\u1ed1c t\u1ebf S\u00e2n bay T\u00e2n S\u01a1n Nh\u1ea5t, \u00e1nh n\u1eafng chi\u1ec1u r\u1ea1ng r\u1ee1 qua c\u1eeda k\u00ednh.\" width=\"1020\" height=\"557\" data-srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-600x327.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-11709\" src=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-1024x559.webp\" alt=\"C\u1eadn c\u1ea3nh b\u00e0n tay du kh\u00e1ch c\u1ea7m \u0111i\u1ec7n tho\u1ea1i iPhone hi\u1ec3n th\u1ecb th\u00f4ng b\u00e1o &quot;K\u00cdCH HO\u1ea0T TH\u00c0NH C\u00d4NG eSIM&quot; v\u1edbi d\u1ea5u t\u00edch xanh, ng\u1ed3i t\u1ea1i qu\u00e1n c\u00e0 ph\u00ea s\u1ea3nh Ga \u0111\u1ebfn Qu\u1ed1c t\u1ebf S\u00e2n bay T\u00e2n S\u01a1n Nh\u1ea5t, \u00e1nh n\u1eafng chi\u1ec1u r\u1ea1ng r\u1ee1 qua c\u1eeda k\u00ednh.\" width=\"1020\" height=\"557\" srcset=\"https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-1024x559.webp 1024w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-300x164.webp 300w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-768x419.webp 768w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-1536x838.webp 1536w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-2048x1117.webp 2048w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-18x10.webp 18w, https:\/\/tansonnhatairport.vn\/wp-content\/uploads\/2026\/03\/Hinh-3-5-600x327.webp 600w\" sizes=\"(max-width: 1020px) 100vw, 1020px\" \/><\/noscript><figcaption id=\"caption-attachment-11709\" class=\"wp-caption-text\">Successful 5G connection in just a few seconds by scanning the QR code at the International Arrivals Terminal (T2) \u2013 Tan Son Nhat Airport.<\/figcaption><\/figure>\n<h2 data-path-to-node=\"41\"><span class=\"ez-toc-section\" id=\"7-cach-kiem-tra-dung-luong-va-gia-han-goi-cuoc-linh-hoat\"><\/span>7. How to check your data usage and renew your plan flexibly.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"42\">While strolling around Saigon or enjoying coffee in the Truong Son area, running out of data unexpectedly can be very inconvenient. To avoid this, you should install your mobile carrier&#039;s app (such as MyViettel, My VNPT) to monitor your actual data usage.<\/p>\n<p data-path-to-node=\"43\">Most travel eSIM packages in 2026 support renewal via e-wallets or international cards. If you see your package is about to expire, you can easily purchase additional data with just a few taps on the app. Don&#039;t wait until the network is completely down to try to top up your balance, because then you won&#039;t have internet access to banking apps or e-wallets.<\/p>\n<h2 data-path-to-node=\"44\"><span class=\"ez-toc-section\" id=\"8-giai-dap-thac-mac-ve-tinh-tuong-thich-thiet-bi-nam-2026\"><\/span>8. Frequently Asked Questions about Device Compatibility in 2026<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"45\">By 2026, most mid-range to high-end smartphones from Apple, Samsung, Google, and Xiaomi will support eSIM. However, models imported from certain specific markets (such as iPhones with dual physical SIMs from Hong Kong or China) may not have integrated eSIM chips.<\/p>\n<p data-path-to-node=\"46\">Before purchasing, check your device by going to settings to see if there is an &quot;Add eSIM&quot; option. If you&#039;re unsure, you can check your device&#039;s IMEI number. Compatibility issues are the most common mistake that leads travelers to waste money when buying eSIMs online. If your device doesn&#039;t support it, traditional physical SIM cards are still available at service counters on the ground floor of the station.<\/p>\n<h2 data-path-to-node=\"48\"><span class=\"ez-toc-section\" id=\"faq-nhung-cau-hoi-thuong-gap-ve-esim-tai-tan-son-nhat\"><\/span>FAQ: Frequently Asked Questions about eSIM at Tan Son Nhat Airport<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-path-to-node=\"49,0,0\"><b data-path-to-node=\"49,0,0\" data-index-in-node=\"0\">Can I use my eSIM to book a Grab ride as soon as I land?<\/b><\/p>\n<p data-path-to-node=\"49,0,0\">Yes, after successfully scanning the QR code, the 5G network will be activated immediately.
