Install eSIM on Samsung Galaxy S23 / S23+ / S23 Ultra
Potentially compatible, not universal: buy only after SIM manager shows Add eSIM and the exact phone is unlocked. Carrier and regional versions can omit eSIM support. You need your QR code (emailed after purchase) and an internet connection to scan it.
Who this guide covers
Covers Samsung Galaxy S23, S23+, and S23 Ultra. Because this generation varies noticeably by model number and market, the handset checks are essential.
Check before you buy
- Settings > Connections > SIM manager > Add eSIM is available

Use abroad
When you land, follow the specific plan terms, then open Settings → Connections → SIM card manager. Select your travel eSIM and enable it for mobile data when ready.
Check compatibility first
Look for Add eSIM under Settings > Connections > SIM manager and confirm the device is network unlocked. Galaxy S23 eSIM support can vary across regional and carrier versions.
Carrier and region: Galaxy S23 eSIM support is especially dependent on model number, country, and carrier firmware. A US, Canadian, or imported S23 can expose different SIM manager options; verify before purchase.
Before you fly
Install while on Wi-Fi and label the plan clearly. Keep the QR email available, but do not repeatedly scan the code if the plan is already installed.
Install vs. activate: Install on Wi-Fi before departure, but wait to enable the line for travel use until arrival if the plan's validity begins on installation. Do not repeatedly scan a QR code after the profile has been added.
Device details cross-check: Samsung Canada: eSIM support. Regional model and carrier support can still differ.
Home line and dual SIM
Use SIM manager to keep the Canadian line available for SMS while assigning mobile data to Voyaio. Disable Canadian roaming and review the preferred SIM before you leave the airport. Keeping the Canadian line enabled can still incur your carrier's roaming or usage charges, especially for calls and SMS; check your carrier's terms before travel.
When you arrive
Choose the Voyaio plan for mobile data when you arrive, turn off roaming on your Canadian line, and restart the phone if network registration takes longer than expected.
Troubleshooting this Samsung Galaxy S23 / S23+ / S23 Ultra guide
Add eSIM is missing
Check the exact model number and software version, confirm the phone is unlocked, and contact the original carrier if the device was sold with restrictions.
The QR code says it was already used
Open SIM manager and look for an existing Voyaio profile instead of scanning again. If it is installed, enable it and assign it to mobile data.
If the phone shows no service, confirm the travel plan is enabled, mobile data is assigned to that line, and data roaming is enabled for the travel eSIM when the provider requires it. Then toggle airplane mode or restart the phone.
