Frequently Asked Questions

HelloRoam city eSIM plans give you data built for specific urban destinations, from Tokyo and Seoul to London and Bali. Pick a city plan, choose your data size (3GB to 20GB for fixed plans, or unlimited by the day), and get your QR code in under 5 minutes. No SIM swap, no surprise bills when you land.

HelloRoam city-specific eSIM data plans connect you to the strongest local networks in each urban destination. Plans start from S$1.32. Fixed data options run 3GB to 20GB, valid for 12 to 30 days. Unlimited daily plans suit heavier users who stream maps, videos, or video calls while travelling.

Singtel DataRoam Saver costs SGD 10 per day and gives you a capped data allowance in most destinations. StarHub Roam Easy and M1 Data Passport also charge around SGD 10 per day with limits that add up fast. HelloRoam city eSIM plans start from S$1.32 with no per-day data cap. Singapore travellers who spend 5 or more days abroad save up to 84% compared to equivalent daily roaming add-ons from Singtel, StarHub, or M1.

Data needs for travel depend on how you use your phone. Light users checking maps and sending messages use about 1GB per day. Streaming music adds roughly 500MB per hour. Video calls take about 700MB per hour. For a 10-day trip with moderate use, a 10GB plan covers most travellers without running short.

Data needs for international travel vary by activity. Maps and messaging use around 300MB to 500MB per day. Social browsing adds 1GB to 2GB per day. Streaming video uses 1GB per hour or more. A 5GB plan covers a light 10-day trip. A 10GB or 20GB plan works better if you rely on navigation apps, video calls, or a mobile hotspot regularly.

StarHub Roam Easy gives you a capped data allowance each day before throttling to lower speeds, which happens quickly for heavy users. Singtel and M1 daily roaming packs work the same way. HelloRoam e-sim plans offer fixed data from 3GB to 20GB with no daily speed cap, so your connection stays consistent as long as data remains in your plan.

HelloRoam accepts Visa, Mastercard, American Express, Apple Pay, Google Pay, and PayPal. All transactions use 256-bit SSL encryption. Prices are shown in SGD. The final checkout charge is processed in USD by our payment provider. Your bank converts the amount on its own. HelloRoam adds no extra fees.

HelloRoam city eSIM plans are data-only. Your Singtel, StarHub, or M1 SIM stays active for calls and texts while the HelloRoam e-sim handles your data in the city. Tethering is included, so you can share your connection with a laptop or tablet. No SIM swap needed on iPhone XS or newer. This setup is ideal for Singapore travellers on business trips to Tokyo, Seoul, or Bangkok.

eSIM delivery is instant. Your QR code and setup instructions arrive by email within 2 to 5 minutes of purchase. Check your spam folder if the email is missing. You can also view and download your eSIM from your HelloRoam account dashboard at any time. No physical shipping, no waiting.

Matching an eSIM Plan to the City on Your Itinerary

City eSIM plans zero in on a single metro area rather than spreading data across an entire country. For Singapore travellers hopping between Tokyo for cherry blossoms, Seoul for shopping, and Bangkok for a long weekend, each plan plugs into the carrier that best covers that particular city. This section walks through choosing the right city plan and estimating how much data your trip style will actually burn through, from a quick JB dash to a fortnight based in London.

Why City Coverage Matters More on Some Trips Than Others

A city eSIM plan connects you to the network covering your specific metro area, which matters because urban trips tend to burn through more data than a quiet countryside stretch of the same holiday. Navigation apps, ride-hailing bookings, and restaurant searches all run constantly through a busy day in Tokyo, Seoul, or Bangkok, in a way they do not on a beach stay or a rural leg of a trip. A city eSIM built around that pattern accounts for the heavier use rather than assuming a light, even pace across your whole itinerary. Fixed plans from 3GB to 20GB cover light to moderate use across a typical city stay. Unlimited daily plans suit travellers who stream video from a hotel room in the evening or share a hotspot with a travel partner while covering a full day of sightseeing on foot.

Sizing a City Plan for a Quick Stopover or a Longer Stay

A short city stop of two or three days, such as a weekend in Bangkok or a stopover in Seoul, usually runs comfortably on a smaller fixed plan covering maps, messaging, and social media. A full week with some video streaming fits a mid-sized fixed plan better. Anything longer, or heavier on data, calls for an unlimited daily option instead. Every city plan page shows the local network type and coverage reach, so you can check it before you pay rather than guessing. A short weekend in Kuala Lumpur looks different on paper from a two-week stay in London, but the buying process stays the same: pick your data size, check out, and scan the QR code once you land. Type it as an eSIM, an e-sim, or an e SIM in the search bar and the same city plan page comes up with identical coverage details. This same city-level model covers Singapore itself, useful if you are booking a plan for a visiting client or family member landing at Changi. Browse the cities catalog, compare fixed and unlimited pricing, and buy before your flight leaves the ground.

City eSIM plans give urban travellers local network data sized to the pace of a specific destination rather than an entire country. Pick your city, match the data size to your stay, and activate before you land. Your eSIM QR code arrives by email, ready to connect the moment your flight touches down at your destination.
