HelloRoam vs Holafly: Honest eSIM Review for UK Travellers

HelloRoam is the better choice for most UK travellers. HelloRoam offers fixed plans from £0.84, covers 185+ countries, and provides 24/7 WhatsApp help in 63 languages. Holafly only offers unlimited daily plans and covers around 60 countries, which limits you if your holiday goes beyond Europe or Latin America.

HelloRoam differs from other eSIM providers by offering both fixed data and unlimited daily plans across 185+ countries, as of April 2026. Airalo, Holafly, and Nomad each limit you to one plan type. HelloRoam also supports 63 languages and includes 24/7 WhatsApp help on every plan at no extra charge, a genuine benefit for UK travellers who need assistance in unfamiliar time zones.

Holafly's unlimited data works under a fair usage policy, not as fully unrestricted data. Holafly applies speed throttling after heavy use within a single day. The specific threshold varies by country and is not always shown upfront. HelloRoam unlimited plans state any speed policies clearly before you buy, so you know exactly what you are getting from the start.

HelloRoam offers better customer support than Holafly for most UK travellers. HelloRoam provides 24/7 live chat and WhatsApp in 63 languages, far more than Holafly's English and Spanish support. For travellers who need help at 2 am in Bangkok or Tokyo, that difference is genuinely significant.

Holafly does not support hotspot sharing on most of its unlimited plans. This is one of the most common complaints in Holafly reviews and Holafly reddit threads. UK travellers who need to tether a laptop or share data with a companion on a long trip abroad will find this a genuine blocker. HelloRoam includes hotspot sharing on all plans, with no separate fee and no restrictions, so you can share your connection from the moment you land.

Holafly's main disadvantages include limited country coverage (around 60 destinations), no fixed data plan option, and restricted hotspot sharing on many plans. Holafly only sells unlimited daily plans, so light users end up paying for data they never use. UK travellers on short city breaks or those who consume modest data often find HelloRoam's fixed plans far more cost-effective.

Holafly suits travellers who want unlimited daily data in popular European and Latin American destinations. Airalo leads on country count (200-plus). HelloRoam gives you both plan types: fixed plans from £0.84 and unlimited daily data across 185+ countries, making it the more flexible choice for most UK travellers heading anywhere.

HelloRoam is one of the best eSIM providers for international travel because it offers both fixed data and unlimited daily plans across 185+ countries. Holafly covers around 60 destinations with unlimited plans only. Airalo covers 200-plus countries with fixed plans only. For UK travellers who want plan flexibility and broad coverage, HelloRoam gives you the most options. Whether you are comparing sim vs esim or esim versus sim for your next holiday, eSIM wins on setup speed, cost, and convenience.

Samsung Galaxy S20 and newer flagship models support eSIM technology. The Galaxy S21 through S24, the Z Flip, and Z Fold series all include eSIM capability. Older Samsung phones and budget-tier Galaxy A-series models may lack support. Check Settings, then Connections, then SIM Manager on your Samsung handset. HelloRoam and Holafly both work on any eSIM-compatible Samsung device.

eSIMs are excellent for international travel. You activate before your flight, connect the moment you land, and pay a flat rate with no surprise charges. HelloRoam eSIM covers 185+ countries with plans starting at £0.84. Compared to UK carrier daily roaming fees from EE, Vodafone UK, O2, or Three, an eSIM saves most travellers 50% or more on data abroad. Whether you ask how can I avoid roaming charges or how to avoid roaming charges, the answer is a dedicated international eSIM. HelloRoam and Holafly both offer eSIM for travel with no SIM swap and instant eSIM activation. Comparing eSIM activation between providers: both use QR-code delivery and activate in under five minutes on any eSIM-compatible phone.

HelloRoam makes it straightforward to buy more data mid-trip. Open the app, choose a new plan for your destination, scan the QR code, and you are connected again. Holafly's unlimited plans reset every day so no top-up is needed. For any fixed plan from either provider, buying extra data takes under five minutes and does not require touching your existing eSIM profile.

HelloRoam eSIM profiles use GSMA encryption and stay locked to your device's hardware, protecting against physical theft. Both an eSIM and a physical SIM connect to the same cell towers, so tracking risk is the same either way. HelloRoam covers 185+ countries with this same encryption standard applied to every plan.

Buying an eSIM without a plan means acquiring an empty profile slot. Most providers, including HelloRoam and Holafly, sell eSIM plans as a bundle with data included. You pick a destination and a data size at checkout. There is no separate step to buy just the eSIM hardware, since it is built into your phone and activated when you purchase a plan.

Converting a physical SIM to eSIM is supported by major UK carriers including EE, Three, Vodafone UK, and O2. Contact your carrier or use their app to start the switch, which typically takes 10 to 15 minutes. This frees up your physical SIM slot. For travel, add a HelloRoam eSIM alongside your carrier eSIM to get affordable data in 185+ countries.

Switching between eSIM profiles takes a few taps on your phone. On iPhone, go to Settings, then Cellular, and pick which line handles data. On Android, open Settings, then Network, and choose your active SIM. HelloRoam travellers keep their UK carrier active for calls and switch to the HelloRoam eSIM for affordable data at their destination.

HelloRoam operates on a pay-as-you-go basis with no contracts, no standing charges, and no cancellation fees. Buy a plan when your trip is confirmed and use it for the duration. Holafly and Airalo work the same way. For UK travellers who go abroad a few times a year, this one-off purchase model means you never pay for data you are not using.

Saily covers refunds on unused eSIM plans that meet their conditions. Open the Saily app and contact support to start a request. HelloRoam also has a refund policy for eligible plan purchases. Buy the plan for the handset you will carry on your trip, as an eSIM is not transferable between devices once installed.

Most modern phones support multiple eSIM profiles. iPhones from the XS onward support dual eSIM, and the iPhone 13 and later can run two eSIMs at the same time. Samsung Galaxy S21 and newer also support multiple eSIMs. You can keep Holafly, Airalo, or your UK carrier on one eSIM and run HelloRoam on another for maximum flexibility on any trip.

Buy HelloRoam eSIM plans directly through the app or at helloroam.com. Select your destination from 185+ countries, choose a fixed or unlimited plan starting at £0.84, and get your QR code by email in under five minutes. Holafly and Airalo also sell directly online with no intermediaries.

HelloRoam offers a refund policy for eligible eSIM purchases. Contact HelloRoam support to check whether your plan qualifies. Holafly also has a refund policy for specific conditions. An eSIM is not transferable between devices once installed, so purchase the plan for the phone you intend to use on your trip.

Holafly offers refunds on unused eSIM plans that meet their eligibility criteria. You must contact Holafly support before installing the eSIM on your device to qualify. Once the profile is installed, refunds are not issued. HelloRoam also provides a refund policy for eligible uninstalled purchases, including a 180-day money-back guarantee. Check the terms from both providers before buying, particularly if your travel dates may change. An eSIM is not transferable between devices once installed.

HelloRoam allows hotspot sharing on all plans, so you can connect a laptop, tablet, or a travel companion's phone to your data. Holafly restricts hotspot sharing on many of its unlimited plans. Check the specific plan details before you buy if sharing a hotspot is important for your trip. Hotspot sharing uses data faster than regular phone browsing, so keep an eye on your allowance.

Top up data on HelloRoam by buying a new plan through the app. Pick your destination, select a data size, scan the QR code, and you are back online in under five minutes. Holafly unlimited plans reset daily with no top-up needed. On fixed plans from either provider, adding more data mid-trip is a quick self-service step that does not require reinstalling the eSIM.

eSIM works on the vast majority of Android phones sold after 2020 in the UK. Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and flagship handsets from OnePlus and Motorola all support eSIM. Open Settings on your Android phone and look for SIM Manager under Network or Connections. Both HelloRoam and Holafly work on any eSIM-capable Android handset.

An eSIM resists hacking better than a physical SIM because it stays locked inside your phone. HelloRoam applies GSMA encryption to every eSIM profile across 185+ countries, protecting your data connection from unauthorised access. SIM swap attacks face much higher barriers with an e-sim than with a removable physical card.
