HelloRoam vs Google Fi: which eSIM is better in 2026?

Google Fi throttles international data based on your plan tier. On the Unlimited Premium plan, Google Fi includes full-speed international data up to 50GB per month, after which speeds drop sharply. On the Flexible plan, Google Fi charges a per-GB fee for data used abroad, which gets expensive quickly. HelloRoam connects you to local 4G and 5G networks in each country. South Africans travelling to London, Dubai, or Sydney use the same local networks as residents.

HelloRoam connects to 212+ networks across 185+ countries with no monthly subscription. Google Fi requires a monthly plan in USD plus a US address and Google account, which bars South Africans from signing up. For South Africans, HelloRoam is not just better: it is the only one of the two they can actually use.

Google says every Pixel 4 and newer works with eSIM. A Pixel 3 or 3a works only when bought in certain markets or from certain carriers. The Pixel 7, 8, and 9 all support dual eSIM profiles. Run your home carrier on one profile and add a HelloRoam travel data plan on the other. On the Pixel, go to Settings, then Network and Internet, then SIMs to manage profiles.

The Google Pixel 9 supports eSIM fully and can hold multiple eSIM profiles at the same time. Keep your South African number active on your Vodacom or MTN SIM while using a HelloRoam eSIM for data in 185+ countries. On the Pixel 9, go to Settings, then Network and Internet, then SIMs, and scan your HelloRoam QR code to add the travel plan. An eSIM is not transferable between devices once installed.

Switching eSIM profiles takes a few taps. On iPhone, go to Settings, then Mobile Service, then Mobile Data, and select the line you want for data. On Android, go to Settings, then Network and Internet, then SIMs (on Samsung, Settings, then Connections, then SIM Manager). Most South African HelloRoam users keep their Vodacom or MTN SIM active for local calls and set HelloRoam as the data line when they land at their destination.

HelloRoam plans start at R 16,79 as a one-time payment with no monthly fee. Vodacom bills roaming data per megabyte or per day pass, and those charges add up fast over a trip. Over a week or two in London, those daily charges keep climbing, while a HelloRoam plan for the UK covers the full trip at one flat prepaid price.

An eSIM is a practical choice for any European holiday. Google Fi charges a recurring monthly fee in USD for plans covering Europe, with speeds capping after heavy usage. HelloRoam's flat-rate Europe plan covers the UK, France, Germany, the Netherlands, Spain, and many other European countries under one purchase. You pay once and stay connected across borders.

An eSIM is worthwhile for any international trip. HelloRoam plans start at R 16,79 with no subscription needed. Vodacom, MTN, and Cell C all charge daily roaming rates that add up quickly over a one- or two-week holiday. A prepaid HelloRoam plan covers your destination at a flat cost, saving South Africans a significant amount on most international routes.

The main trade-offs with eSIM are needing a compatible phone (such as iPhone XS and newer, most Samsung Galaxy S20 and newer models, and Google Pixel 4 and newer), needing Wi-Fi for initial setup, and the fact that an eSIM is not transferable between devices once installed. These are minor compared to the savings over Vodacom, MTN, or Cell C daily roaming rates and the freedom from monthly carrier contracts.

HelloRoam offers eSIM plans for South Africans visiting the United States. Connect to local US networks at 4G and 5G speeds the moment your flight lands at JFK, LAX, or other US airports. Plans are prepaid with no monthly commitment. Google Fi covers the US but requires a US address, making it inaccessible to South African visitors arriving on tourist or business visas.
