China has 5G mobile coverage in Beijing and main cities. China Unicom are the core networks. For Irish visitors, China is outside the EU, so Irish carrier EU roaming does not apply. A HelloRoam eSIM from $3.52 is typically far cheaper than international daily roaming add-ons. A HelloRoam eSIM means you arrive in Beijing connected without hunting for a SIM card at the airport. 175+.
Sort your data before your flight from Dublin
Buy your HelloRoam eSIM for China at home, activate it over Wi-Fi, and enable data when you land in Beijing. You skip the airport telecom queues entirely and step off the plane already connected.
Keep your Irish number active
On a dual SIM phone, keep your Eir, Three IE, or Vodafone IE SIM for calls and texts while using HelloRoam for data in China. Family and colleagues back in Ireland can still reach you on your regular Irish number.
Offline maps save data on city breaks
Download Google Maps or Maps.me for Beijing offline before you leave Ireland. Offline navigation saves data and works even in indoor areas with weaker signal. China cities are generally well covered but rural areas can be patchy.
Travel insurance and emergency numbers
Bring your EHIC or travel insurance details. The emergency number in most countries is 112 or local equivalents. Your HelloRoam eSIM keeps emergency apps, insurance portals, and the Irish embassy contact details accessible throughout your China trip.
Currency and card acceptance
Notify your Irish bank before travelling to China. Card acceptance is generally good in Beijing but carry some local currency for smaller vendors and public transport. Currency conversion apps work well on a HelloRoam data connection.
HelloRoam connects on China Unicom in China. These are the leading 5G networks in China with strong coverage in Beijing and major tourist areas. Your eSIM automatically selects the best available signal.

David T.An eSIM (embedded SIM) is a digital SIM card built into your mobile, tablet, or smartwatch. It lets you activate a data plan without inserting a physical chip. An e-sim is reprogrammable, so you can switch plans or carriers instantly on eSIM compatible phones like iPhone 14, Samsung Galaxy S23, or Google Pixel 8. The whole process takes under five minutes via QR code.
Your mobile supports eSIM if Settings shows an 'Add eSIM' or 'Add Cellular Plan' option. Most flagships released after 2018 support it: iPhone XS and newer, Samsung Galaxy S20 and above, and Google Pixel 3 and later. You can also dial *#06# to check for an EID number. Visit HelloRoam's device compatibility page for the full list.
Installing a HelloRoam eSIM takes three steps. First, buy your plan and receive your QR code by email within minutes. Second, go to Settings, then Cellular or Mobile Data, then Add eSIM. Third, scan the QR code and confirm. The whole process takes 2 to 5 minutes. Make sure you have Wi-Fi while setting it up.
eSIM activation usually takes 2 to 10 minutes after you scan the QR code. If it takes longer, try restarting your device, toggling aeroplane mode on and off for 30 seconds, confirming the eSIM profile is set as the active data line, or checking that you have good network coverage in your area.
Most modern mobiles support dual SIM, letting you run a physical SIM and an eSIM at the same time. Keep your Eir, Vodafone IE, or Three Ireland number active for calls while your HelloRoam eSIM handles data in China. You stay reachable at home without paying Irish roaming charges.
5G support on HelloRoam eSIMs depends on the local carrier network in your plan and your device's 5G capability. Many HelloRoam plans include 5G access where partner networks provide coverage in major cities. Your device must support 5G bands used in China, and you connect automatically to the fastest available network.
You can check data usage in two ways. First, via the HelloRoam Dashboard: log into helloroam.com to see real-time usage, remaining balance, and plan expiry. Second, via device settings: on iPhone go to Settings, then Cellular, then your eSIM line. On Android go to Settings, then Network and Internet, then Data Usage. Dashboard figures update every 15 to 30 minutes.
HelloRoam offers a 180-day refund window for unused eSIM plans bought for China. If you have activated and used data, partial refunds cover the unused portion. Contact support with your order ID and refunds typically process within 5 to 14 business days.
QR codes are single-use for security. If you need to reinstall, use the reinstall option in your HelloRoam account or contact our support team for a fresh activation method.
HelloRoam support is available 24/7 through live chat, WhatsApp, and email at help@helloroam.com. Average response time is under five minutes. The team can help with setup, troubleshooting, plan changes, and refund requests.
