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.
