Google Fi covers 200-plus countries, but google fi international data speeds depend on your plan tier and your monthly usage. Google fi overseas customers on the Flexible plan pay 10 USD per GB. HelloRoam covers 185+ with full-speed local network access on every plan. Kiwis heading to Bangkok, Tokyo, London, or Bali get reliable 4G LTE and 5G through HelloRoam with no throttling based on last month's usage. A google fi review will confirm the coverage, but the US-only signup blocks New Zealanders from accessing it at all.
Google Fi plans run from 20 USD per month (Simply Unlimited) to 65 USD per month (Unlimited Plus) for their google fi international plan. That bill comes in every month whether you travel or not. Google fi not available outside us is the core limitation for Kiwis: New Zealand residents cannot sign up without a US mailing address and a US Google account. HelloRoam plans start at NZ$1.95 as a one-time purchase. No monthly subscription, no carrier contract. Buy a plan for your UK trip, use it, and pay nothing until your next holiday.

The Google Fi Flexible plan charges 10 USD per GB for google fi overseas data. The Unlimited Plus plan caps full speed at 50GB monthly. Kiwis who stream maps, use rideshare apps, or video call family from abroad can hit those limits in under a week. HelloRoam gives you a dedicated local data connection at full speed with no throttling at any point in your trip. That is what a proper google fi alternative looks like for travellers who need consistent speeds.
Google Fi routes data through US-based servers even when you're abroad. That routing adds latency and reduces speeds. HelloRoam connects directly to local carriers in 185+, giving you local speeds without any routing delay. Keep your Spark, 2degrees, or One NZ SIM active for calls and texts while HelloRoam handles your data. In a google fi vs HelloRoam comparison, Kiwi travellers save consistently by choosing HelloRoam. No monthly bills after your trip ends.

HelloRoam is the right pick for Kiwi travellers who want pay-as-you-go data, full-speed connections abroad, and support in their language with no US account needed. Google Fi works if you already use it as your US carrier and want a single monthly bill covering domestic and google fi international calling. For Kiwis, google fi is not available outside us, so HelloRoam is the only practical google fi alternative.

Google Fi is not available to New Zealand residents. It requires a US mailing address and a US Google account to sign up. Google fi is not available outside us, which rules it out for Kiwis entirely. HelloRoam is the practical option for Kiwis heading overseas, whether you're flying out of Auckland, Wellington, or Christchurch. Buy a plan online, complete eSIM activation in under 5 minutes, and have it installed before you board.
HelloRoam covers Australia with direct connections to Telstra, Optus, and Vodafone AU networks. Kiwis on a cross-Tasman trip can activate a plan before leaving Auckland and be online the moment they land in Sydney or Melbourne. Plans start at NZ$1.95 with no monthly subscription. Google Fi requires a US address, which rules it out for New Zealanders as a google fi alternative.
HelloRoam covers Fiji and a range of Pacific destinations popular with New Zealand travellers. Activate a plan before leaving Auckland and have reliable data at your resort from day one. There's no US account or special setup needed. Scan the QR code and you're connected.
Spark's international roaming packs charge a daily rate plus data limits, and speeds often drop after your daily allowance runs out. HelloRoam connects to local networks abroad at full speed for a single flat payment. For a week in Thailand or a UK trip, HelloRoam gives you better value and no bill shock when you get home.
2degrees offers international roaming on a day pass model at NZD 8 to NZD 15 per day depending on your destination. A 10-day trip to London adds NZD 80 to NZD 150 on top of your regular plan. HelloRoam charges a flat one-time prepaid fee starting at NZ$1.95 with no daily charges. For longer trips, the difference in cost is significant.
One NZ charges daily roaming rates with capped data speeds on international packs. HelloRoam gives you full local network speeds for a single payment. Kiwis on longer trips, like an OE or a working holiday, find pay-per-trip eSIM plans far more cost-effective than daily carrier charges that pile up over weeks or months.
HelloRoam covers the UK with connections to EE, Vodafone UK, and O2. Kiwis heading to London for an OE, work, or to visit family can set up the e-sim at home before departure from Auckland and be online immediately at Heathrow or Gatwick. Plans are prepaid with no contracts. Google Fi covers the UK but is not available to NZ residents, making HelloRoam the only practical google fi alternative here.
Japan is one of the fastest-growing destinations for Kiwi travellers, and staying connected there is important for navigation and booking transport. HelloRoam connects to NTT Docomo and SoftBank networks at full speed. A HelloRoam Japan plan costs a fraction of what Spark, 2degrees, or One NZ charge for daily international roaming.
HelloRoam covers Indonesia including Bali with connections to Telkomsel and XL Axiata networks. Kiwis heading to Bali for a holiday can activate a plan before leaving Auckland and have data ready at Ngurah Rai International Airport. Plans are prepaid and affordable, well suited for the budget-conscious Kiwi traveller.
Google Fi's Unlimited Plus plan includes google fi international data but caps full-speed access at 50GB per month. After that, speeds slow much. The Flexible plan charges 10 USD per GB used google fi overseas. HelloRoam delivers full local network speeds with no throttling. When comparing eSIM versus SIM options for international travel, a dedicated travel eSIM like HelloRoam gives you predictable costs that carrier plans like Google Fi cannot match.
On a dual SIM phone, keep your Spark SIM for NZ calls and texts while using HelloRoam for data abroad. Set HelloRoam as the data line in your phone settings when you land overseas. Your NZ number stays active for incoming calls and texts. You don't miss anything from home while you're travelling.
HelloRoam's pay-per-trip model is ideal for OE travellers who move between countries and don't want a long-term plan. Buy a plan for each country or region as you go. HelloRoam covers 185+, so you're sorted for the UK, Europe, Southeast Asia, and the US without switching providers. Plans start at NZ$1.95. Note that eSIM profiles are not transferable between devices once installed.
Buy your HelloRoam plan online at home or at Auckland International Airport using the terminal Wi-Fi. Open your confirmation email, scan the QR code, and follow the prompts in your phone's eSIM settings. The whole process takes about five minutes. The eSIM activates when you land at your destination, so nothing extra is needed on arrival.
HelloRoam covers Thailand with connections to AIS and DTAC. It's a popular destination for budget-conscious Kiwi travellers, and HelloRoam gives you full-speed local data from the moment you land in Bangkok or Phuket. Plans are prepaid at a flat rate. Compare this to One NZ or Spark daily roaming charges that add up quickly over a two-week holiday.
HelloRoam has no US address or account requirements. Any person with an eSIM-compatible phone, an email address, and an international payment card can buy a plan from anywhere in New Zealand. This is the main practical difference from Google Fi, which requires a US presence to sign up at all. HelloRoam is the only realistic google fi alternative for Kiwis.
Your 2degrees plan stays active in the physical SIM slot. HelloRoam runs on the eSIM slot. You keep your NZ number for incoming calls and texts while HelloRoam handles your data at local network speeds. Set HelloRoam as the data line in Settings when you land. Your 2degrees plan is not charged international roaming fees while HelloRoam is handling data abroad.
iPhones sold in New Zealand from the iPhone XS and later support eSIM. Most NZ models are sold unlocked, so they work with HelloRoam immediately. If your iPhone is locked to Spark, 2degrees, or One NZ, contact your carrier to request an unlock before adding a HelloRoam e-sim. The unlock process is free after your minimum term.
HelloRoam covers the United States with local carrier connections. Kiwis on a J-1 visa, au pair placement, or working holiday can activate a HelloRoam plan before leaving Auckland for short-term data on arrival. When you settle in, you can switch to a US-based monthly plan. HelloRoam keeps you connected while you sort things out. An eSIM profile is not transferable between devices once installed.
It's worth it even for a short trip to Sydney or Melbourne. A HelloRoam eSIM saves money compared to Spark, 2degrees, or One NZ daily roaming charges. Plans for Australia start at NZ$1.95 with no daily fees. You're sorted for the whole trip without worrying about bill shock when you return home.
HelloRoam supports hotspot sharing on all plans. Turn on Personal Hotspot and connect your travel companion's phone, your laptop, or your tablet. This is handy for couples or friends travelling together where one person has the eSIM plan and others connect through it. For a long trip, individual plans per device give each person their own full-speed connection.
HelloRoam covers the USA with local carrier connections at 4G and 5G speeds. Kiwis visiting New York, Los Angeles, or Hawaii can activate a plan before departure from Auckland and be connected immediately on arrival. Plans start at NZ$1.95 with no monthly subscription. Google Fi covers the USA but requires a US address, which most New Zealanders don't have, so HelloRoam is the practical google fi alternative.
Open the HelloRoam app, choose your current destination, and pick a new data plan. Scan the QR code and your extra data is added straight away. Plans start at NZ$1.95. This is particularly useful for longer trips across Australia or Europe where you use more data than expected.
HelloRoam offers regional plans covering multiple countries under one purchase. Kiwis on European trips or multi-country Southeast Asia itineraries can use a single regional plan across several destinations. This is more convenient and often more affordable than buying separate country plans for each stop on a longer trip.
Your phone needs to support eSIM (most unlocked phones from 2019 onwards do), you need a Wi-Fi connection to install the eSIM before your trip, and you can't move the eSIM to another device after it's set up. These are minor trade-offs. The main upside is paying a flat rate instead of daily carrier charges from Spark, 2degrees, or One NZ.
HelloRoam is a solid pick for Kiwis heading to Australia, the UK, Japan, Thailand, Bali, Fiji, or any of 185+. Plans start at NZ$1.95 with no monthly fees. There's no US account needed, unlike Google Fi. Setup takes five minutes, and 24/7 WhatsApp support is there if anything goes wrong.
