Google Fi covers 200-plus countries, but Google Fi international data speeds vary by plan tier and monthly usage cap. Google fi overseas customers on the Flexible plan pay USD 10 per GB. HelloRoam covers 185+ with full-speed local network access on every plan. Travellers flying from Changi to Tokyo, Seoul, Melbourne, or London get reliable 4G LTE and 5G speeds through HelloRoam with no throttling tied to prior month usage. A google fi review confirms the coverage, but Singapore residents cannot sign up because google fi is not available outside us.
Google Fi plans range from USD 20 per month (Simply Unlimited) to USD 65 per month (Unlimited Plus). You pay that bill every month whether you travel or not. Google fi not available outside us is the hard stop for Singapore travellers: you cannot create an account without a US mailing address. HelloRoam plans start at S$1.45 as a one-time purchase. No monthly subscription, no carrier contract. Buy a plan for your trip to Tokyo or Bangkok, use it, and pay nothing until your next trip out of Changi.

The Google Fi Flexible plan charges USD 10 per GB when used overseas. The Unlimited Plus plan includes google fi international data but caps full speed at 50GB monthly. Travellers who stream maps, use Grab abroad, or video call back to Singapore can hit those limits quickly. HelloRoam gives you a dedicated local data connection at full speed with no throttling at any usage level. That is what a true google fi alternative for Singapore travellers delivers.
Google Fi routes your data through US-based servers even when you are overseas. That routing adds latency and reduces effective speeds. HelloRoam connects directly to local carriers in 185+, giving you true local speeds without the routing delay. You keep your Singtel, StarHub, or M1 SIM active for calls and texts while HelloRoam handles your data abroad. In any google fi vs HelloRoam comparison, Singapore travellers benefit from HelloRoam's no-US-account model and flat-rate pricing. No monthly bills after your trip ends.

HelloRoam is the right choice for Singapore travellers who want pay-as-you-go data, full-speed connections abroad, and support in their language with no strings attached. eSIM vs physical SIM: HelloRoam delivers instant eSIM activation via QR code, no SIM card swap needed. Google Fi works only for US residents who already use it as their primary carrier. Google fi is not available outside us, which makes HelloRoam the only viable google fi alternative for Singapore-based travellers. Choosing a travel eSIM helps you avoid Singtel, StarHub, and M1 roaming charges that a US-centric plan like Google Fi cannot eliminate.

Google Fi is not available to Singapore residents. It requires a US mailing address, a US billing method, and a Google account linked to a US profile.

Anyone with an eSIM-compatible phone can purchase a plan and install it before departing Changi Airport. HelloRoam covers 185+ countries. Plans start from S$1.45.

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.

Plans start from S$1.45.
M1 charges daily roaming fees with tiered data speeds across different destination zones. HelloRoam bypasses carrier routing by connecting directly to local networks at your destination, giving you true local speeds. For Singaporeans making frequent short trips to KL, Bangkok, or Taipei, HelloRoam's prepaid model is more cost-efficient than daily roaming charges from M1.
eSIM-compatible phones let you keep your Singtel SIM in the physical slot for Singapore calls and SMS while HelloRoam handles data abroad.

For business travellers who depend on fast, reliable data, unthrottled access is a clear advantage over google fi overseas limitations.

It covers 185+ at local network speeds, has no US address requirement, and charges a flat prepaid rate from S$1.45 with no monthly fees.

iPhones sold in Singapore from the iPhone XS onwards support eSIM. Most Singapore iPhones are sold without carrier restrictions, so HelloRoam works straight away. If your iPhone is carrier-locked to Singtel, StarHub, or M1, contact your carrier to have the restriction removed. Go to Settings, then Cellular, then Add eSIM to install a HelloRoam plan. Note that an eSIM cannot be transferred to another device once installed. Plans start from S$1.45.
Most modern flagship phones support multiple eSIM profiles. On iPhone XS and newer, you can store multiple eSIMs and switch between them. On Samsung S21 and newer, dual eSIM is supported. Keep your Singapore carrier eSIM for local use and add HelloRoam for international trips. Switch your data line in phone settings when you travel. Plans start from S$1.45.
HelloRoam supports hotspot sharing on all plans. Turn on Personal Hotspot and connect a companion's phone, your tablet, or your work laptop to your HelloRoam data connection. This is useful for business travellers who need to keep a laptop connected during transit or in hotel rooms. For each device that needs its own fast independent connection, separate plans are the better option.

HelloRoam covers Vietnam with Viettel and Mobifone network connections. Singapore travellers heading to Ho Chi Minh City or Hanoi for holidays or business can activate a plan before departing SIN. Plans are prepaid with full local 4G speeds. Vietnam is a growing short-haul destination for Singaporeans and HelloRoam makes staying connected straightforward. Plans start from S$1.45.
Your phone must support eSIM (most flagship phones from 2019 onwards do), you need Wi-Fi to install the eSIM before departure, and the eSIM cannot be transferred to another device after installation. These are minor constraints. The clear benefit is paying a flat prepaid rate instead of daily carrier roaming charges from Singtel, StarHub, or M1 on every trip.
Samsung Galaxy S21 and newer flagship models sold in Singapore support eSIM, as do the Galaxy Z Flip and Z Fold series. Go to Settings, then Connections, then SIM Manager to check eSIM availability on your device. Budget Samsung A-series models do not typically include eSIM support. Unlocked Samsung flagship models work with HelloRoam straight away. Plans start from S$1.45.

Taiwan is a popular destination for Singapore travellers, and HelloRoam gives you full local data speed from Taoyuan International Airport on arrival. Plans are prepaid and affordable.
