WHY 9ESIM?

Built for travellers who switch networks often

Five features that put 9eSIM above any other physical eSIM card on the market.

Switch profiles in seconds

All your carriers stay on the card. Swap networks via the SIM Toolkit menu instantly — no QR re-scans, no support calls.

Bring your own data

Works with every GSMA-compatible eSIM provider. Use a major travel eSIM, your home carrier, or a regional telco — load whichever profile fits the trip.

Open eUICC standard, no account login

Any LPA can write profiles directly to the card — no vendor account required. Your card keeps working even if a vendor (us included) ever shuts down.

GSMA-certified security

Every card carries a SAS-UP certified secure element — the same security tier carriers ship in their own embedded SIMs.

Reusable, no rewrite limits

Erase and rewrite profiles as often as you like. The card outlives any single carrier and any single trip.

Your eSIM universe on one card

Hardware, software, and a community programme — pick the card that matches how you travel and add the rest as you go.

9eSIM V3

The flagship card, made in the UK

1.5 MB of on-card storage holds up to 50 eSIM profiles, and the Kigen OS secure-element stack switches between them in under a second. STK menu support means even iPhone users can swap profiles without the app.

PICK YOUR CARD

Four cards. Same software. Pick what fits.

All four 9eSIM cards run the same open-source LPA stack and switch profiles via STK menu. They differ in storage, profile count and OS layer — and the B1 adds Bluetooth, so an iPhone needs no reader.

COMPATIBILITY

Works with every modern phone

* Compatibility note: 9eSIM cards are physical SIMs, not eSIM-only — the phone must accept a card in its SIM slot. On iOS and some Huawei builds the OS restricts third-party apps from talking to the SIM, so writing new profiles needs a USB-C card reader (or an Android phone) for any non-Bluetooth card model. Switching between already-loaded profiles still works on-card via the SIM Toolkit menu.

HOW TO USE

From box to live network in 4 steps.

STEP 1

Download the app

Get the 9eSIM app on Android (or any open-source LPA on macOS / Windows / Linux).

STEP 2

Insert the card

Slide 9eSIM into a SIM slot on Android, or a card reader for iPhone and HarmonyOS users.

STEP 3

Write a profile

Pick an eSIM and write it to the card.

STEP 4

Use anywhere

Move the card to any device. Connect.

WHAT BUYERS SAY

Trusted by travelers, devs, and dual-SIM seekers.

A representative slice of feedback from public reviews on AliExpress, Trustpilot, MyBestSim, and the RedFlagDeals / Howard Forums pSIM threads.

Used it across five countries with no hiccups. After the first 15-minute setup, every profile switch is under 30 seconds.

Verified buyer · AliExpress

Works on my iPhone with the USB reader exactly as described. The STK menu lets me swap profiles without opening the app.

Reviewer · Trustpilot

The open-source LPA was the deciding factor — if the company disappears tomorrow, my card still works.

Forum thread · RedFlagDeals

I have been using it for 1.5 years now. Used with several phones. Besides working well, the service and support are even better.
