Question 1

What is an eSIM?

Accepted Answer

An eSIM is a digital SIM card built directly into your phone. What an eSIM does is store a carrier plan as a downloadable profile, so there is no physical card to lose or swap. You purchase a plan online, scan a QR code to install it, and your phone connects to a local network at your destination. HelloRoam provides eSIM plans in 175+ countries across 145+ carrier networks, giving you local data rates without paying daily roaming fees to Eir, Vodafone IE, or Three Ireland.

Question 2

How does a HelloRoam eSIM work?

Accepted Answer

How does an eSIM work in practice: a HelloRoam eSIM stores your data plan as a digital profile inside a chip built into your phone. You buy a plan on the HelloRoam website or app, receive a QR code by email, scan it in your phone settings, and the profile installs in minutes. When you land, your phone connects to a local carrier network automatically. Your Irish mobile number on your home SIM stays active for calls and texts the whole time you are away.

Question 3

Can I have more than one eSIM on my phone?

Accepted Answer

Most modern phones can store several eSIM profiles at once. iPhones from the XS onward and most Android flagship handsets from 2020 onward support two or more eSIM profiles. HelloRoam covers 175+ countries, so you can have a Spain plan, a USA plan, and a regional Europe plan all saved on one phone and switch between them as needed.

Question 4

Is an eSIM safe to use?

Accepted Answer

A HelloRoam eSIM is as secure as a physical SIM because both use carrier-level encryption defined by the GSMA eSIM security specification. Accessing an eSIM profile requires the same level of authentication as cloning a physical SIM card. Keep your phone software updated, use a strong PIN, and buy plans only from trusted providers for best practice. Ireland's Data Protection Commission enforces GDPR, and HelloRoam is fully compliant.

Question 5

Is an eSIM worth it for Irish travellers?

Accepted Answer

An eSIM saves Irish travellers a significant amount compared to standard carrier roaming outside the EU. Eir charges from €4.99 per day for non-EU destinations, Vodafone IE charges €6.99 per day, and Three Ireland rates vary by country. HelloRoam plans start from €1.37 for a fixed data allowance covering your chosen destination and trip length, with no daily fees and no ongoing charges.

Question 6

What are the downsides of using an eSIM?

Accepted Answer

The main downside of an eSIM is that older handsets and most budget phones do not support it. An eSIM profile is also not transferable between devices once installed. You cannot move it to a new phone the way you would a physical SIM card. Check your handset supports eSIM before purchasing, and keep your QR code email safe in case you need to contact support.

Question 7

How do I know if my phone supports eSIM?

Accepted Answer

Your phone supports eSIM if you see an option labelled Add eSIM or Add Mobile Plan under your network or mobile data settings. iPhones from the XS model (2018) onward include eSIM. Most Samsung Galaxy S20 and newer handsets support it, as do Google Pixel 3 and newer. Check your handset model on the HelloRoam compatibility page if you are not sure before buying.

Question 8

What is the best eSIM app for international travel?

Accepted Answer

HelloRoam is a strong choice for managing eSIM plans across 175+ countries from a single app, starting from €1.37. eSIM iPhones from the XS onward, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer all work with HelloRoam. The app lets you track data usage, top up, and manage multiple destination plans from your phone, with support available 24/7 by WhatsApp and email.

Question 9

What is the best eSIM for travel to the USA?

Accepted Answer

HelloRoam is a strong option for Irish visitors heading to New York, Boston, or Chicago. Plans start from €1.37, far below what Eir, Vodafone IE, or Three Ireland charge for non-EU roaming. Buy online before you fly from Dublin, get your QR code by email, and you have data the moment you land and clear customs. No SIM kiosk queuing, no waiting at arrivals.

Question 10

Which eSIM is best for international travel from Ireland?

Accepted Answer

HelloRoam covers 175+ countries with both fixed data and unlimited daily plans from €1.37. For Irish travellers, this covers all the key holiday destinations: Spain, Portugal, France, the UK, Italy, and Greece. HelloRoam works as a full international data plan and travel sim card replacement, giving you mobile data abroad at local rates without Eir, Vodafone IE, or Three Ireland roaming fees. Prepaid travel data, roaming free data, and no contracts. Compared to Airalo eSIM, HelloRoam offers both fixed and unlimited plans with 24/7 WhatsApp support. Plans connect to the same local carrier networks used by residents, giving you real speeds rather than deprioritised tourist data.

Question 11

What does HelloRoam cover?

Accepted Answer

HelloRoam covers 175+ countries through 145+ carrier connections. Fixed data plans run from 3GB to 20GB with validity from 7 to 30 days. Unlimited plans suit daily streaming and video calls. Pricing starts from €1.37, which is far below the daily roaming rates from Irish carriers when you travel outside the EU.

Question 12

How do I install a HelloRoam eSIM?

Accepted Answer

Installing a HelloRoam eSIM takes under two minutes on most handsets. After purchasing, you receive a QR code by email. On iPhone, go to Settings, then Mobile Data, then Add eSIM, and scan the code. On Android, go to Settings, then Network and Internet, then SIMs, and add a new plan. The profile installs and your phone connects to the local carrier at your destination automatically.

Question 13

How do I activate my HelloRoam eSIM?

Accepted Answer

Activating your HelloRoam eSIM is straightforward. Scan the QR code from your confirmation email through your phone mobile data or cellular settings. Select Add eSIM, point your camera at the code, and the profile installs. Most plans activate automatically when you arrive at your destination. Some plans let you pick a manual start date.

Question 14

Can I switch back to my Irish SIM while abroad?

Accepted Answer

Switching back to your home SIM is simple. Go to your phone mobile data or cellular settings, select your Eir, Vodafone IE, or Three Ireland SIM, and set it as the active data line. Your HelloRoam eSIM profile stays saved on your phone unless you delete it. You can switch between the two whenever you need, so both are always ready.

Question 15

How do I make sure I am using my eSIM data and not my home SIM?

Accepted Answer

When you use a HelloRoam travel eSIM, make sure your mobile data is routed through the HelloRoam line in your cellular settings. Turn off data roaming on your Eir, Vodafone IE, or Three Ireland SIM to avoid any unexpected charges. On iPhone, go to Settings, then Mobile Data, and confirm the HelloRoam line is set as your primary data SIM.

Question 16

Why is my eSIM not activating?

Accepted Answer

eSIM activation fails most often because of a weak Wi-Fi connection or a QR code that has already been scanned once. Connect to a reliable Wi-Fi network, restart your phone, and try scanning the QR code again using a fresh screenshot of the original email. If the problem continues, contact HelloRoam support by WhatsApp or email and the team will sort it out.

Question 17

What do I do if my eSIM is not working abroad?

Accepted Answer

HelloRoam covers 175+ countries through 145+ carrier networks. If your HelloRoam eSIM is not working abroad, first check that mobile data is routed through the HelloRoam line in your settings. Toggle aeroplane mode off and on to force a network reconnection. If you are still stuck, WhatsApp or email support responds in under two hours on average.

Question 18

How much does a travel eSIM cost compared to Irish carrier roaming?

Accepted Answer

HelloRoam plans start from €1.37, which is a fraction of what Irish carriers charge for roaming outside the EU. As of early 2026, Vodafone IE charges €6.99 per day for non-EU roaming, Eir charges from €4.99 per day, and Three Ireland rates vary by country. A 7-day HelloRoam fixed data plan for Spain or Portugal costs far less than a week of daily roaming passes from any Irish carrier.

Question 19

Do HelloRoam unlimited eSIM plans work well for holidays?

Accepted Answer

HelloRoam unlimited data plans suit Irish travellers who stream, join video calls, or post heavily on social media while on holiday. You choose the number of days you need and the plan runs until it expires. Unlimited plans include a daily high-speed allowance. Once that is used in a given day, data continues at a reduced speed to keep you connected.

Question 20

Unlimited eSIM vs fixed data: which is better for me?

Accepted Answer

The right plan depends on how you use your phone on holiday. Light users checking maps, messages, and the odd search do well with a fixed data plan of 5GB or 10GB. Heavy users who stream, make video calls home, or work remotely suit unlimited better. HelloRoam offers both types starting from €1.37, so you can match the plan to your trip.

Question 21

How much does a HelloRoam eSIM cost for Irish travellers?

Accepted Answer

HelloRoam fixed data plans start from €1.37, making them far cheaper than daily roaming add-ons from Eir, Vodafone IE, or Three Ireland when travelling outside the EU. Your HelloRoam eSIM does not change your Irish mobile number and does not add any charges to your home bill. You pay once for the plan and that is everything included.

Question 22

Are HelloRoam eSIM plans prepaid with no contract?

Accepted Answer

HelloRoam eSIM plans are fully prepaid. You pay upfront for the data and number of days you choose, with no contract, no monthly bill, and no automatic renewal. There are no hidden charges. Your payment covers exactly the data and duration shown at checkout, nothing more.

Question 23

Can I use one eSIM plan across multiple countries?

Accepted Answer

HelloRoam global plans cover 175+ countries so you stay connected across most of the world on one purchase. Regional plans cover Europe, Asia, the Americas, and more at a lower price than buying separate single-country plans. For Irish travellers doing a multi-stop European trip, one regional plan covers the whole itinerary without any bother.

Question 24

What is the cheapest eSIM option for Irish travellers?

Accepted Answer

HelloRoam offers some of the most affordable eSIM plans available, with fixed data starting from €1.37. Destinations popular with Irish holidaymakers include Spain, Portugal, France, the UK, and the USA. Irish travellers visiting New York, Barcelona, Paris, or Lisbon can get a plan that costs less than a single daily roaming pass from any Irish carrier.

Question 25

Does HelloRoam offer local eSIM plans for popular Irish holiday destinations?

Accepted Answer

HelloRoam eSIM plans connect to the same local carrier networks used by residents in each country, giving you local rates rather than international roaming prices. Single-country plans are available for specific destinations. Regional plans cover multiple countries at once. HelloRoam covers both the USA and the UK, the two most popular non-EU destinations for Irish travellers.

Question 26

How do I check my remaining eSIM data?

Accepted Answer

You track your HelloRoam eSIM data usage inside the app, which shows your remaining balance and active plan details at a glance. Your phone's built-in mobile data settings also show data used per SIM line. If your data is running low, buy a top-up through the app or website and it applies to your balance straight away.

Question 27

Can I top up my HelloRoam eSIM data while abroad?

Accepted Answer

You top up your HelloRoam eSIM by opening the app or website and purchasing extra data for your active plan. Top-ups apply straight away to the same countries your plan already covers. This is the easiest way to add more data if you are running low on a long holiday or extended trip.

Question 28

Can I use my HelloRoam eSIM as a hotspot?

Accepted Answer

You can share your HelloRoam eSIM data with other devices by switching on your phone hotspot or tethering feature. Go to your phone settings, enable the hotspot, and connect your tablet, laptop, or a travel companion's device. This uses data from your HelloRoam plan, so keep an eye on your balance if you are tethering for extended periods.

Question 29

What do I do if I have a problem with my HelloRoam eSIM?

Accepted Answer

If you have a problem with your HelloRoam eSIM data plan, contact support through WhatsApp or email and include your order number. The support team resolves most issues in under two hours. Common fixes include toggling aeroplane mode, confirming the correct data line is active, and checking that data roaming is switched off on your home SIM line.

Question 30

How do I contact HelloRoam support?

Accepted Answer

HelloRoam customer support is available by WhatsApp and email 24/7. You can reach the team before you fly from Dublin, Cork, or Shannon, while you are away in Spain or Portugal, or once you are back home. Average response time is under two hours. No bother at all to get in touch.

Question 31

What is HelloRoam refund policy?

Accepted Answer

HelloRoam refunds eSIM plans that have not been activated or used. Once you scan the QR code and install the plan, it counts as activated and is not eligible for a refund. If you have not yet activated your plan and need a refund, contact support through WhatsApp or email with your order details and the team will sort it out for you.

Question 32

How do I reach HelloRoam customer support?

Accepted Answer

You reach HelloRoam customer support through WhatsApp or email from the HelloRoam website or app. Support is available 24/7 and responds in under two hours on average. Have your order number ready and a brief description of the issue and the team will have it sorted in no time.

Question 33

What happens if I accidentally delete my eSIM?

Accepted Answer

If you delete your HelloRoam eSIM by accident, contact support straight away with your order number. The team can help you re-download the profile if the plan is still active. Most carriers allow one re-download per eSIM profile, so act quickly if this happens and the team will guide you through it.

Question 34

Can I switch between different eSIM plans on my phone?

Accepted Answer

Switching between HelloRoam eSIM plans is simple because all your saved profiles appear in your phone cellular or mobile data settings. Tap the profile you want to use and set it as the active data line. No technical knowledge needed. This makes it easy to switch between your Irish home SIM and your HelloRoam holiday plan whenever you need.

Question 35

Are HelloRoam eSIMs good for short breaks and long weekends?

Accepted Answer

HelloRoam travel eSIMs are ideal for short breaks because you pay only for the days you need. Plans are available from just a few days, so you are not paying for data you will not use. A long weekend in Barcelona or a few nights in London is fully covered without committing to a week-long plan.

Question 36

How do I know my HelloRoam eSIM is working?

Accepted Answer

Your HelloRoam eSIM is active when your phone shows signal bars and you can browse without Wi-Fi. Check your phone mobile data settings, where the active eSIM will show a connected status. The HelloRoam app also shows your plan status and remaining data balance at a glance so you always know where you stand.

Question 37

What happens when my eSIM data runs out?

Accepted Answer

If your HelloRoam eSIM data runs out, open the app or website and buy a top-up or a new plan for your destination. Top-ups add data to your active plan straight away, so you are back online in minutes. Sorted.

Question 38

How does eSIM work?

Accepted Answer

How does eSIM work? An e-sim stores a carrier data plan as a digital profile inside a chip built directly into your phone. You buy a plan from HelloRoam, receive a QR code by email, and scan it in your phone settings. Your phone connects to a local partner carrier network when you land. No plastic SIM card is needed. eSIM compatible phones include eSIM iPhones from the XS onward, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. The profile installs in under 5 minutes. For multi-country trips, a HelloRoam world eSIM regional plan covers multiple destinations on a single purchase.

Question 39

What is the best eSIM for Ireland travel?

Accepted Answer

HelloRoam is the best eSIM for Irish travellers who want to skip Eir, Vodafone IE, and Three Ireland roaming charges outside the EU. Plans start from €1.37, cover 175+ countries, and arrive as a QR code within minutes of purchase. You get local 4G and 5G speeds at your destination without touching a physical SIM card

Question 40

Does an eSIM work in Europe from Ireland?

Accepted Answer

An eSIM works across EU countries the same way a regular Irish SIM would under standard EU roaming rules, but for destinations outside the EU, your Eir, Vodafone IE, or Three Ireland plan may charge daily roaming add-ons. A HelloRoam eSIM covers both EU and non-EU destinations from €1.37 with no daily roaming fee and no carrier contract.

Question 41

Can I use an eSIM in the USA from Ireland?

Accepted Answer

Yes, an eSIM works in the USA from Ireland. HelloRoam offers USA eSIM plans connecting to local 4G and 5G networks in New York, Boston, Chicago, Los Angeles, and beyond.

Question 45

Question 46
