Common questions about Bangkok eSIM

What is an eSIM?

An e-sim is a digital SIM card built directly into your mobile, tablet, or smartwatch. It lets you activate a prepaid plan without inserting a physical chip. eSIM cards are reprogrammable, so you switch carriers or plans instantly on eSIM compatible phones like iPhone 14, Samsung Galaxy S23, or Google Pixel 8. The whole process takes under 5 minutes via QR code.

How do I know if my mobile supports eSIM?

Your mobile supports eSIM if it shows an 'Add eSIM' option under Settings. Most eSIM compatible phones include iPhones from XS onward, Samsung Galaxy S20 and later, and Google Pixel 3 and above. You can also dial *#06# to check for an EID number. Check HelloRoam's device compatibility page for a full list.

How do I install an eSIM from HelloRoam?

Installing a HelloRoam eSIM takes three simple steps. First, open your mobile settings and select 'Add eSIM' or 'Cellular Plan'. Second, scan the QR code from your email. Third, confirm the installation and your eSIM activates within minutes. You can set it up at home before heading off.

Common questions about Bangkok eSIM

eSIM activation takes 2 to 10 minutes on most carrier networks after you scan the QR code. If activation takes longer, try these steps: restart your device, toggle aeroplane mode on and off for 30 seconds, make sure the eSIM profile is set as your active data line, or check you're in an area with decent coverage.

Most modern mobiles support dual SIM, letting you run one physical SIM and one eSIM card at the same time. eSIM vs physical SIM NZ travellers compare: eSIM wins on speed and convenience, physical SIM suits older handsets. Keep your NZ number active for calls and texts while using HelloRoam eSIM for data in Bangkok. An eSIM also beats prepaid phone cards for international calls because data-based calling through WhatsApp is cheaper and clearer.

5G support on HelloRoam eSIM cards depends on the local carrier network included in your plan and your device's 5G compatibility. Many HelloRoam plans include 5G access where partner networks offer coverage in major cities. Your device must support 5G bands used in Bangkok, and you'll automatically connect to the fastest available network (5G, 4G LTE, or 3G) based on coverage.

You can check your HelloRoam eSIM data usage two ways: (1) HelloRoam Dashboard: log into your account at helloroam.com to view real-time data usage, remaining balance, and plan expiry date. (2) Device Settings: on iPhone, go to Settings, then Cellular, then your eSIM line. On Android, go to Settings, then Network and Internet, then Mobile Network, then Data Usage. Dashboard data updates every 15 to 30 minutes.

HelloRoam offers a 180-day refund window for unused eSIM plans. If you've activated and used data, partial refunds apply to the unused portion. Contact support with your order ID and refunds typically process within 5 to 14 business days.

HelloRoam eSIM is cheaper than Spark, Vodafone NZ, and 2degrees international roaming for most overseas trips. Spark charges around NZ$8 per day for international roaming. Vodafone NZ and 2degrees run similar daily rates that add up fast on a two-week holiday. HelloRoam eSIM plans for Bangkok start from $2.74 per day on local 4G LTE and 5G networks, with no surprise bills and no carrier contract. For a 14-day trip, the savings over a Spark roaming pass can be significant.
