A few things to know before you scan the QR code:

  • Open the QR code on a second device (your laptop or another phone) before you start scanning.
  • Stay on Wi-Fi throughout. Losing connection mid-install can cause errors.
  • Each QR code works for one scan only. After a successful scan, the code expires.
  • Do not delete the eSIM after installing it. An eSIM is not transferable between devices once installed, so deleting it means losing your plan.

Before you start:

  • Wait until you land at your destination before activating your eSIM. eSIM activation is automatic once you land and turn Data Roaming on.
  • Switch on airplane mode, then reconnect to Wi-Fi so your home carrier does not charge you.
  • Save this guide as a PDF so you can follow along without an internet connection.

Samsung Galaxy Tips Worth Knowing

  • OneUI 6.0+ UsersOn OneUI 6.0 and newer, SIM Manager may appear as 'SIM card manager' under Settings > Connections. The path and steps are identical.
  • Dual eSIM SupportGalaxy S24 supports two active eSIMs at the same time. Keep your Singapore number live while running a HelloRoam travel data plan in Japan, South Korea, or Thailand.
  • Update FirstRunning the latest OneUI version reduces eSIM errors. Update your Galaxy before you leave Singapore.

FAQs

Samsung phones with eSIM support include the Galaxy S20, S21, S22, S23, and S24 series (Plus, Ultra, and FE variants), Z Fold 2 through Z Fold 5, Z Flip through Z Flip5, and the Note 20 series. These are among the most widely used eSIM compatible phones for Singaporean travellers. Your Galaxy needs OneUI 3.0 or later (Android 11 or higher). Most A-series budget models do not include eSIM hardware, so check your model specs on Samsung's site before you purchase a plan.

SIM Manager on Samsung Galaxy sits at Settings > Connections > SIM Manager. On OneUI 6.0 and newer, it may appear as SIM card manager under the same path. If you cannot find it, type SIM Manager in the Settings search bar and the option appears right away.

HelloRoam eSIM installs on Samsung without a QR code through manual entry. Open Settings, tap Connections, tap SIM Manager, tap Add eSIM, then choose Enter activation code manually. Type the SM-DP+ address and activation code from your HelloRoam confirmation email. Both codes arrive in the same email within 5 minutes of purchase.

Samsung Galaxy S24, S24+, and S24 Ultra support dual eSIM, so two eSIM profiles run at the same time with no physical SIM card required. This is useful for Singaporeans heading to Japan or South Korea who want to keep their home number active while running a HelloRoam local data plan. Manage both lines at Settings > Connections > SIM Manager. Note that this eSIM is not transferable to another device once installed.

Try these 4 fixes when your Samsung is not reading the eSIM QR code: update OneUI to the latest version, confirm the phone is carrier-unlocked, clean the camera lens, and scan in good light at about 15 cm distance. If none work, use manual entry. Open SIM Manager, tap Add eSIM, choose Enter code manually, and type the SM-DP+ address and activation code from your HelloRoam email.
