David T.An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone, tablet, or smartwatch. It lets you activate mobile plans electronically without inserting a physical SIM card. Unlike traditional SIM cards, eSIMs are reprogrammable. You can switch networks or plans instantly through software on compatible devices like iPhone 14, Samsung Galaxy S23, or Google Pixel 8.
To check if your phone supports eSIM, go to Settings, then Mobile Data (iPhone) or Settings, then Network & Internet (Android) and look for 'Add eSIM' or 'SIM card manager' options. Most flagship phones released after 2018 support eSIM, including iPhone XS and newer, Samsung Galaxy S20+, Google Pixel 3+, and many modern Android devices. You can also dial *#06# to see if an EID (eSIM identifier) appears.
To install your HelloRoam eSIM, follow these 3 steps: (1) Purchase your plan from the HelloRoam dashboard and receive your QR code via email within minutes, (2) Open Settings, then Mobile Data, then Add eSIM on your device (iPhone) or Settings, then Network & Internet, then Mobile Network (Android), (3) Scan the QR code or enter the manual activation code to complete installation in 2 to 5 minutes. Make sure you are connected to Wi-Fi during setup.
eSIM activation is usually instant but can take 2 to 10 minutes depending on network conditions and signal strength. If activation takes longer than 10 minutes, try these steps: restart your device, toggle aeroplane mode on and off for 30 seconds, check that the eSIM profile is set as your active data line, or confirm you are in an area with good network coverage.
Yes, most modern smartphones support dual SIM, letting you use one physical SIM card and one eSIM at the same time. This is ideal for South African travellers who want to keep their Vodacom, MTN, or Cell C number active for calls and texts whilst using a HelloRoam eSIM for affordable data overseas. You can choose which SIM handles calls, messages, and data in your device's mobile data settings under 'Primary' or 'Default' line options.
5G support on HelloRoam eSIMs 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 5G coverage in major cities and urban areas. Your device must support 5G bands used in the Thailand (check device specifications), and you'll automatically connect to the fastest available network (5G, 4G LTE, or 3G) based on coverage availability.
You can check your HelloRoam eSIM data usage in two ways: (1) HelloRoam Dashboard: log into your account at helloroam.com to view real-time data consumption, remaining balance, and plan expiry date. (2) Device Settings: on iPhone, go to Settings, then Mobile Data, then your eSIM line. On Android, go to Settings, then Network & Internet, then Mobile Network, then Data Usage. Dashboard data updates every 15 to 30 minutes, whilst device-level usage is tracked locally and may differ slightly from network reporting.
Refund eligibility varies by plan. Generally, refunds are available if the eSIM has not been installed or activated. Contact support with your order ID for refund requests. Once approved, refunds typically process within 5 to 14 working days depending on payment provider and bank processing times.
QR codes are typically single-use for security. If you need to reinstall, use the reinstall option in your account or contact support for a new activation method.
Contact HelloRoam support through multiple channels: (1) Live chat available 24/7 on our website at helloroam.com/contact, (2) Email us at help@helloroam.com with your order ID for faster help (average response time under 2 hours), (3) Use the in-app Help section for instant answers to common questions, or (4) Check our FAQ database. For urgent issues whilst travelling overseas, live chat is the fastest option.
