On Wi‑Fi, open Settings → Connections → SIM manager → Add eSIM, then Scan QR code from service provider and scan your TripoSIM QR code. Approve the download and label the line "TripoSIM." In SIM manager, keep your home SIM as the preferred line for calls and texts, and set mobile data to TripoSIM. When you land, enable roaming for the TripoSIM line. Install before you fly — validity starts on first data use.
Samsung Galaxy phones are some of the easiest devices to run a travel eSIM on, thanks to Samsung's clear SIM manager. This guide covers installing and activating a TripoSIM eSIM on the Galaxy S25 and S24 series, the Z Fold and Z Flip foldables, and supported A‑series models — plus how to keep your normal number while using TripoSIM for data, and what to do if something doesn't work.
Does your Samsung Galaxy support eSIM?
Most recent flagship and foldable Galaxy phones support eSIM: the Galaxy S25, S24, S23, S22 and S21 series (excluding some FE/regional variants), and the Z Fold and Z Flip foldables. Support on A‑series phones varies by model and region — some mid‑range and regional variants ship without eSIM even when a global version has it. Two checks before you buy a plan:
- Confirm eSIM on your exact model and region. In Settings → Connections → SIM manager, an Add eSIM option means your phone supports it.
- Confirm it's carrier‑unlocked. A locked Galaxy can refuse a travel eSIM even if the hardware supports one.
Install your TripoSIM eSIM on Samsung Galaxy (step by step)
Have your TripoSIM QR code ready on another screen (laptop, tablet, printout, or the order email on a second device). Then:
<!--howto-->
- Connect to Wi‑Fi and open Settings → Connections → SIM manager.
- Tap Add eSIM (Samsung may briefly search for nearby plans).
- Choose Scan QR code from service provider.
- Scan the TripoSIM QR code and follow the prompts to add the plan.
- Tap Add / Confirm to approve the eSIM download — keep Wi‑Fi on until it finishes.
- Label the line "TripoSIM" so it's easy to tell apart from your home SIM.
- In SIM manager, keep your home SIM as the preferred line for calls and messages.
QR on the same Galaxy? If you can't scan from a second screen, use the manual details (SM‑DP+ address + activation code) from your TripoSIM order via Add eSIM → Enter activation code, or display the QR on another trusted device.
Activate TripoSIM for data when you arrive
Samsung's SIM manager makes dual‑SIM simple — keep your number on your home line and send data through TripoSIM:
| Setting | Where (SIM manager) | Set to |
|---|---|---|
| TripoSIM line | SIM manager | ON |
| Preferred SIM — Calls / Messages | SIM manager → Preferred SIM | Home SIM |
| Preferred SIM — Mobile data | SIM manager → Preferred SIM | TripoSIM |
| Data roaming (TripoSIM) | Connections → Mobile networks → Data roaming | ON |
| Data roaming (home SIM) | Connections → Mobile networks | OFF |

Enabling Data roaming for the TripoSIM line is required for a travel eSIM abroad and costs nothing extra because the plan is prepaid. Keep it off for your home SIM to avoid carrier fees. Wait for a local network, then test with Wi‑Fi turned off.
TripoSIM is data‑only: your Galaxy's home SIM stays active for calls and SMS (so bank codes still arrive on your number), while apps like WhatsApp and Google Meet use your TripoSIM data.

Don't delete the eSIM first — the QR is generally single‑use.

|---|---|---|
| No "Add eSIM" in SIM manager | Your exact model/region supports eSIM; software is updated | Update One UI; search Settings for "eSIM"; confirm carrier unlock |

| No data after landing | TripoSIM line ON, mobile data = TripoSIM, roaming ON for TripoSIM | Toggle Airplane Mode; pick the local network manually |

Frequently asked questions
How do I set up an eSIM on my Samsung Galaxy? On Wi‑Fi, open Settings → Connections → SIM manager → Add eSIM, choose Scan QR code from service provider, scan your TripoSIM QR code and approve the download. Keep your home SIM for calls, set mobile data to TripoSIM, and turn on roaming for the TripoSIM line when you arrive.
Which Samsung Galaxy phones support eSIM? The Galaxy S25, S24, S23, S22 and S21 series and the Z Fold and Z Flip foldables support eSIM (excluding some FE/regional variants). A‑series support varies by model and region, so check for an Add eSIM option in SIM manager.
Where is the eSIM option on a Samsung Galaxy? Settings → Connections → SIM manager → Add eSIM. If you don't see it, your model or regional variant may not support eSIM, or One UI needs updating.
Will a travel eSIM change my Samsung's phone number? No. It's a separate data line. Your home SIM keeps your number for calls and texts; the eSIM only adds data abroad.
Do I need to turn on data roaming on my Galaxy? Yes — enable data roaming for the TripoSIM line only. A travel eSIM uses partner networks abroad (treated as roaming) but the plan is prepaid, so there's no extra charge. Keep roaming off on your home SIM.
Should I install the eSIM before travelling? Yes — install on Wi‑Fi before you leave. TripoSIM plan validity starts on first data use in your destination, so you can install early and connect the moment you land.
Can I use two eSIMs on a Samsung Galaxy? Many recent Galaxy models support multiple eSIM profiles (with one active data line at a time) plus a physical SIM. You can store your TripoSIM travel eSIM alongside your home SIM and switch data between them in SIM manager.
Why won't my Samsung eSIM connect after I land? Check that the TripoSIM line is ON, mobile data is set to TripoSIM, and data roaming is ON for that line. Then toggle Airplane Mode or select the local network manually. Don't delete the eSIM — contact support first.
