Cheapest eSIM for 185+ Countries. Instant Data for Every Trip.

HelloRoam covers 185+ countries (185+ in total) through 204+ carrier networks, with both fixed and unlimited e-sim plans. Fixed data plans cover 3GB to 20GB for shorter trips, and unlimited daily plans suit longer stays or heavy usage. Manage everything in one app with no new SIM card or new account for each country you visit. Coverage includes every major destination from ASEAN to Europe to the Americas.

HelloRoam eSIM regional plans work across multiple countries on a single purchase. The Europe plan covers 34 EU countries, Southeast Asian plans cover ASEAN nations, and the Americas plan covers countries across North and South America under one flat fee. Single-country plans cover only your chosen destination. Travellers doing Japan and Korea, or a multi-city Europe trip, will find regional plans the more cost-effective option.

HelloRoam eSIM plans require no contract for any purchase. You pay upfront for the data size and duration you need, and the plan expires after the period ends. No monthly bills, no auto-renewals, no lock-in. Buy exactly what you need for your destinations, then top up if you need more data mid-trip.

A 5GB eSIM plan covers a 1-week trip with maps, messaging, and light browsing without streaming video. Streaming one hour of HD video uses roughly 1.5GB, so 5GB gives about 3 hours of video plus regular daily use. A short Japan or Korea trip typically needs 5GB for a 4 to 5-day stay. For heavier use, a 10GB plan gives more room.

Unlimited eSIM plans suit frequent video streamers, daily video call users, and travellers uploading large files regularly. Fixed data eSIM plans work better for trips under 2 weeks or when Wi-Fi is available at hotels and offices. HelloRoam offers both plan types from S$1.32 across 185+ countries, so you match the plan to your actual phone usage, whether it is a short JB trip or a month across Europe.

HelloRoam covers 185+ countries through 204+ carrier networks as of April 2026. Coverage includes top travel destinations: Japan, South Korea, Thailand, Malaysia, Indonesia, Australia, United Kingdom, and Europe. Visit the HelloRoam coverage page and search your destination to see available eSIM plans and pricing before you buy.

Google Pixel phones support eSIM from the Pixel 3 onwards. A HelloRoam eSIM works on Pixel 3, 4, 5, 6, 7, 8, and 9 series devices for international travel. Go to Settings, then Network, then SIM manager, and tap Add eSIM. Note that an eSIM is not transferable once installed, so confirm your Pixel model supports eSIM before you purchase a plan.

HelloRoam provides country-specific eSIM data plans for popular destinations including Thailand, Indonesia, and Taiwan. Your plan connects to each country's local 4G and 5G networks from the moment you land. Plans cover the full country, so you stay connected outside the main city as you travel around. Short-haul stops like Penang, Phuket, and Bali are all covered.

Android phones support eSIM travel plans on most flagship models from 2019 onwards. Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and select OnePlus and Motorola models are eSIM compatible phones. Check your Android phone settings for an Add eSIM option under Network or SIM manager to confirm before purchasing a HelloRoam plan. Most modern phones support two eSIMs on one phone, so you keep your home number active while using travel data.

HelloRoam travel esim plans start from S$1.32 for fixed data. M1 Data Passport charges around S$10 per day as of April 2026, the same as Singtel DataRoam Saver and StarHub Roam Easy. A 10-day HelloRoam international esim plan to Japan or Europe typically costs a fraction of that total. Prepaid travel data means you pay once for your international data plan, not per day for mobile data abroad.

HelloRoam connects to 4G and 5G networks in 185+ countries. Speed depends on the local carrier network at your destination. Japan, South Korea, Australia, and most major European cities offer reliable 5G or 4G LTE coverage through HelloRoam partner networks. Speed is the same as what local residents use on those networks.

HelloRoam's most popular eSIM plans for trips from the region cover Japan, South Korea, Thailand, Malaysia, and Indonesia. These plans offer 3GB to 20GB of fixed data or unlimited daily connectivity. Japan and Korea plans are especially popular during cherry blossom season in March and April, and Korea autumn in October and November. All popular plans include instant QR code delivery by email after checkout. 185+ S$1.32

HelloRoam offers cost-effective eSIM plans for international travel with fixed data starting from S$1.32. Prices vary by destination and data size. Regional plans cover multiple countries at a lower per-country rate than buying separate SIM cards at each destination. The cheapest eSIM Singapore option for a short-haul trip is a fixed data plan for Malaysia, Indonesia, or Thailand.

HelloRoam does not sell an eSIM profile without a data plan included. Every purchase includes a specific data allowance and validity period. To test your device before your trip, buy the smallest available plan and activate it when you arrive at your destination. You do not need to install the eSIM immediately after purchase.

To buy data on an eSIM, select a plan through HelloRoam's website or app, choose your destination and data size, and complete checkout. You receive a QR code by email. Scan the code in your phone's cellular settings to install the plan. If you need more data mid-trip, buy a top-up through the app in under 5 minutes. No new QR code scan is needed for top-ups.

Purchase a local eSIM online through HelloRoam's website or iOS and Android app in under 5 minutes, covering 185+ countries. Search your destination, pick a data plan, pay securely, and get your QR code by email. No store visit, no passport required, no waiting in any queue. Scan and install before you board at Changi and you are ready to connect on arrival.

Add more data to your HelloRoam eSIM by purchasing a top-up through the app or website. HelloRoam covers 185+ countries through 204+ carrier networks and offers a 180-day money-back guarantee. Top-ups credit to your active plan right away, so you are back online within minutes. You do not need to delete or reinstall your eSIM profile. HelloRoam is operated by FutureSyncs Ltd, a UK-registered company with 24/7 support via WhatsApp and email.

HelloRoam international eSIM plans start from S$1.32 as a one-time prepaid fee. GOMO is Singtel's budget sub-brand focused on local Singapore mobile plans, not international roaming packages. TPG Singapore does not offer comprehensive international roaming at competitive day pass rates. HelloRoam gives you local 4G and 5G rates in 185+ countries, which is a better deal than any of the local carrier daily pass options for trips over three days.

An eSIM is harder to hack than a physical SIM because no one can physically remove and clone it. GSMA SGP.22 encryption protects all HelloRoam eSIM profiles against unauthorised access. HelloRoam encrypts all account data and recommends enabling two-factor authentication on your account for added security when using your travel esim plans.

An e SIM registers on local carrier towers as part of normal network operations, the same as any cellular connection. HelloRoam does not sell or share your location data with third parties. Your data stays between your device and the carrier network. Adding a VPN app on your device encrypts your traffic for extra privacy when using travel data abroad.

iPhone 15 supports eSIM and works with HelloRoam travel data plans. The iPhone 15 series operates without a physical SIM tray, so your HelloRoam e-sim is the only plan on the device alongside your primary eSIM line. Go to Settings, tap Cellular, then tap Add eSIM. Scan the QR code from your HelloRoam email and your travel plan installs in under 3 minutes.

iPhone 14 and newer models support dual eSIM with no physical SIM tray. iPhone XS through iPhone 13 support one physical SIM plus one eSIM. Samsung Galaxy S21 and newer support dual e SIM. Google Pixel 7 and newer support dual eSIM profiles. Confirm your phone supports eSIM by checking Settings for an Add eSIM or Add Cellular Plan option.

HelloRoam fixed data plans start from S$1.32. Holafly focuses on unlimited daily plans at higher per-day rates than HelloRoam's fixed options. HelloRoam gives you both fixed and unlimited plans so you match the plan to your trip length and data usage. For a 10-day Europe trip with light browsing, a fixed HelloRoam plan costs less than Holafly's unlimited option.

Saily offers affordable eSIM plans backed by NordVPN's parent company. HelloRoam covers 185+ countries and includes 24/7 WhatsApp support plus a 180-day guarantee. Saily's strength is privacy features from its VPN heritage. HelloRoam's strength is broader ASEAN coverage and round-the-clock support availability for travellers departing from Changi.

Nomad eSIM offers fixed data plans for 100 countries. HelloRoam covers 185+ countries with both fixed and unlimited options, supports 63 languages, and accepts 31+ currencies. Both providers use local carrier networks for fast speeds. HelloRoam also includes 24/7 WhatsApp support specifically useful for travellers in ASEAN time zones.

A HelloRoam eSIM for Malaysia covers Johor Bahru with local 4G LTE data from the moment you cross the Causeway. You do not need a Singtel, StarHub, or M1 roaming add-on. A 1-day or 3-day fixed data plan from HelloRoam costs a fraction of any Singapore carrier day pass at S$10. Install before you leave, activate when you land in JB, and you are connected at the mall, on Grab, or at the restaurant without carrying a second SIM.

HelloRoam eSIM for Indonesia covers Batam and Bintan island with local 4G data from S$1.32. Buy a short 2-day or 3-day plan before your ferry ride. Singtel DataRoam Saver and StarHub Roam Easy charge S$10 per day for Indonesia roaming. HelloRoam costs a fraction of that for the same weekend. Scan the QR code at home, hop on the ferry, and connect on arrival at Batam Centre or Tanah Merah Ferry Terminal.

HelloRoam Japan eSIM gives you local 4G LTE and 5G data for cherry blossom trips in March and April. Plans cover Tokyo, Osaka, Kyoto, and the whole country from a single QR code. Activate before your Changi departure and connect the moment you land at Narita or Kansai. Singtel DataRoam Saver charges S$10 per day for Japan. A 10-day HelloRoam Japan plan costs far less. Regional plans also cover Japan and Korea in one purchase for multi-stop itineraries.

HelloRoam South Korea eSIM provides local 4G and 5G data for ski trips to Pyeongchang, Yongpyong, and Vivaldi Park. Coverage runs from Seoul to the mountain resorts. Plans start from S$1.32 as a prepaid fee with no S$10/day StarHub Roam Easy charge. Buy a 7-day or 10-day plan before your Changi flight, scan the QR code at home, and arrive connected at Incheon without any kiosk queue.

Singtel DataRoam Saver charges S$10 per day for international roaming. HelloRoam eSIM covers the same destinations as a flat prepaid fee with no daily billing. On a 7-day Japan trip, Singtel DataRoam Saver costs S$70 in roaming charges. A HelloRoam Japan plan for the same trip costs a fraction of that total. HelloRoam connects to the same local carrier networks at local data rates. Your Singtel SIM stays active for calls and texts while HelloRoam handles all data through a separate dual SIM line.

HelloRoam eSIM works for NSmen travelling overseas for holidays, reservist exercises, or ATEC activities in countries where HelloRoam has coverage. Buy a plan before departure, scan the QR code, and keep your Singtel, StarHub, or M1 SIM active for local calls and texts through dual SIM. For countries like Australia, Taiwan, the United States, or the United Kingdom, HelloRoam provides affordable local data without adding S$10/day to your Singapore carrier bill.

Install your HelloRoam e SIM at home or at the airport gate before your flight. The eSIM stays dormant on your phone until you reach your destination. Set it up at JFK, LAX, SFO, ORD, ATL, or any US airport using your existing Wi-Fi or cellular connection. The QR code scan takes under 2 minutes. Your travel eSIM activates the moment your phone connects to a foreign network after landing.

HelloRoam prepaid e-sim plans cost about the same as a local airport SIM card but save you the time and hassle of finding a vendor, dealing with language barriers, and showing your passport. Local SIM kiosks at European and Asian airports often mark up prices by 30% to 50%. HelloRoam plans start from S$1.32 in USD, and you buy before you leave home.

Most modern iPhones and Samsung Galaxy phones store 8 or more e SIM profiles at once. You can pre-load plans for Japan, Italy, and Mexico before a multi-stop trip and switch between them in Settings. Only one data eSIM is active at a time. HelloRoam also offers regional plans that cover multiple countries under one purchase, so you may not need separate plans at all.

Google Pixel 3 and all newer Pixel models support eSIM. Pixel 7, 8, and 9 series support dual e SIM alongside your existing carrier line. Go to Settings, then Network, then SIM manager, and tap Add eSIM. Scan the HelloRoam QR code from your email. Your phone connects to a local network in 185+ countries the moment you land.

HelloRoam offers short-duration e-sim plans that work for quick border crossings to Canada or Mexico. A 3-day or 7-day plan covers a weekend getaway from cities like San Diego, Detroit, Buffalo, or El Paso. Plans start from S$1.32 in USD. Skip the T-Mobile or AT&T daily roaming fees and use local data at local speeds instead.

Using your HelloRoam eSIM data is safer than public Wi-Fi at hotels, airports, and cafes. Cellular data runs through encrypted carrier networks. Public Wi-Fi exposes you to packet sniffing and man-in-the-middle attacks. For extra protection, pair your e SIM connection with a VPN app. HelloRoam eSIM profiles meet GSMA SGP.22 security standards.

Your phone must be carrier-unlocked to add a HelloRoam e-sim. AT&T, T-Mobile, and Verizon all unlock phones once they are fully paid off. Check by going to Settings, then Cellular, and looking for an Add eSIM option. If you see it, your phone supports eSIM. If your carrier has not unlocked the device yet, contact them and request an unlock before your trip.

HelloRoam eSIM data works with Uber, Lyft (where available), Google Maps, Apple Maps, and all ride-hailing and navigation apps. Offline maps save some data, but live traffic, ride requests, and turn-by-turn directions need a data connection. A 3GB e SIM plan covers about a week of daily navigation and ride-hailing use. No separate SIM card needed.

An international phone plan from AT&T, T-Mobile, or Verizon adds daily roaming fees to your existing bill. A HelloRoam e-sim is a prepaid data plan you buy once and use until it expires. No daily charges, no bill surprises, no contract changes. You keep your US carrier plan active for calls and texts while HelloRoam handles data abroad. Plans start from S$1.32 in USD.

Go to Settings, then Cellular on iPhone or SIM manager on Android. Tap your HelloRoam e SIM line and set it as the primary data line. Your AT&T, T-Mobile, or Verizon line stays active for calls and texts. When you return home, switch your data line back to your US carrier in the same menu. The whole swap takes about 10 seconds.

HelloRoam e-sim connects to 5G networks where available in your destination country. Many carriers in Japan, South Korea, UK, Germany, and other popular travel spots offer 5G. Your phone falls back to 4G LTE where 5G is not yet live. Speeds depend on local carrier coverage, not your US plan. Works on any 5G-capable iPhone, Samsung Galaxy, or Google Pixel device.

HelloRoam beats Airalo on three points for Singapore travellers: unlimited daily data plans, 24/7 WhatsApp support, and 63 languages. Airalo covers more countries (200-plus) and suits small fixed Airalo eSIM data plans. For trips from Singapore to Japan, Korea, or Thailand, HelloRoam offers more plan flexibility and faster support when something goes wrong mid-trip. For most frequent flyers from Changi, HelloRoam is the better eSIM provider.

HelloRoam is the strongest Airalo alternative for Singapore travellers. HelloRoam offers unlimited daily plans (Airalo is fixed-data only, with no Airalo unlimited data option), 24/7 WhatsApp support in 63 languages, and plans from S$1.32 per trip with no monthly subscription. Saily esim and Saily esim reviews suggest Saily is another Airalo alternative, but Saily covers fewer countries than HelloRoam. For very remote destinations outside HelloRoam's 185+-country catalogue, Airalo's broader fixed-data list may fill the gap.

Airalo is a legitimate eSIM provider trusted by millions worldwide with solid App Store and Google Play ratings. Airalo uses GSMA-certified eSIM technology and operates in more than 200 countries. The answer to "is Airalo legit" is yes: it is a real, working eSIM service. HelloRoam is also a legitimate eSIM provider with carrier connections in 185+ countries across 204+ networks, and adds unlimited plans and 24/7 WhatsApp support.

HelloRoam is the better pick for most Singapore travellers. HelloRoam offers both fixed data plans and unlimited daily options across 185+ countries, with 24/7 WhatsApp support in 63 languages. Holafly covers 170+ destinations with unlimited plans only, which limits you if your trip goes to Australia, South Asia, or Africa. Fixed plans start from S$1.32, often cheaper than Holafly's daily rate.

Holafly's unlimited data operates under a fair usage policy, not truly unlimited in the conventional sense. Holafly applies speed throttling after heavy use within a single day. The specific threshold varies by country and is not always displayed before purchase. HelloRoam unlimited plans state any speed policies clearly before you buy, so Singapore travellers know exactly what they are getting before they pay.

Mint Mobile is a US-only carrier. Singapore residents cannot sign up because Mint Mobile requires a US mailing address, a US payment method, and a US phone number to activate. HelloRoam has no such restrictions. Any traveller departing from Changi Airport can purchase a HelloRoam plan online and install it before their flight. HelloRoam covers 185+ countries. Plans start from S$1.32.

StarHub's WorldRoam plans charge per day with a data allowance that often runs out quickly on a busy travel day of maps, photos, and navigation. HelloRoam provides full local network data for a one-time payment. For a week in Bangkok or Phuket, HelloRoam saves you a meaningful amount compared to StarHub's daily international roaming charges. Plans start from S$1.32.

HelloRoam covers South Korea with connections to KT and SK Telecom networks. Seoul and Jeju are popular with Singapore travellers, and HelloRoam gives you full 5G speed from the moment you land at Incheon International Airport. Activate your plan before leaving SIN. Plans are prepaid with no monthly commitment and no throttling. HelloRoam covers 185+ countries. Plans start from S$1.32.

Airalo introduced unlimited data plans with fair usage throttling in select markets as of April 2026. All Airalo eSIM plans are fixed Airalo eSIM data packages. Once you use your data, you need to buy another package or top up. HelloRoam offers both fixed data and unlimited daily plans, so Singapore travellers on longer trips to Japan, Korea, or Europe get better value with HelloRoam's unlimited option.

Samsung Galaxy S20 and newer flagship models support eSIM, along with the Z Flip and Z Fold series. Most budget A-series phones do not support it. Check your phone under Settings, then Connections, then SIM Manager to confirm. HelloRoam and Holafly both work on any eSIM-compatible Samsung device. HelloRoam covers 185+ countries across all supported Android models.
