## What is SefereSIM?

SefereSIM sells prepaid travel eSIMs for 204 destinations. Choose where you are going, see the full price before you sign in, pay with Apple Pay or a card, and install the eSIM on this iPhone with one tap. Your phone is online when you land.

WHY TRAVELERS USE IT
- One-tap install on this iPhone, or a QR code for another phone.
- Most plans start when the eSIM first connects at your destination, so installing at home is safe.
- Every plan and its price is on screen before you sign in. The number at checkout is the number charged.
- See the data left on each eSIM, and top up the same eSIM when you run low.
- When a plan runs out, the data stops. No overage, no surprise bill at home.
- Refunded if your eSIM never activates.

HOW IT WORKS
1. Pick a destination, or answer a few questions and get a plan that fits the trip.
2. Sign in and pay with Apple Pay or a card. An account keeps your plans and install codes in one place.
3. Install with one tap. When you land, choose the eSIM for mobile data.

WHERE IT WORKS
Single-country plans for places like Türkiye, Japan, the United States, the United Kingdom, Thailand and most of Europe, plus regional plans for Europe, Asia and the Middle East. In Türkiye, Canada and Laos, Premium plans run on selected local networks.

YOUR NUMBER STAYS
Your usual SIM keeps your number for calls and texts. SefereSIM carries the mobile data. Each plan says before you buy whether it can receive text messages.

BEFORE YOU BUY
Your iPhone needs to support eSIM and be carrier unlocked. iPhone XS and later support eSIM. iPhones sold in mainland China use two physical SIMs and can't use eSIM.

The app is available in English and Turkish.

## Version history (last 3 releases)

### 1.0.2 — 2026-11-05

- Now on iPhone Duo: SefereSIM now fills both displays. The store shows more destinations at once on the large display, plan and checkout screens keep your plan in view on the small one, and the install QR code brightens the display you're actually looking at, even when you fold or unfold mid-scan.
- Starter plans now cost less.
- Unlimited plans for 7, 14 or 30 days: a full-speed allowance every day, then slower but never cut off, with one payment for the whole trip.
- Find my plan: answer two quick questions from the Store any time to get a plan that fits your trip.
- Save your install QR code as an image, for a router or a second device.
- Links from seferesim.com now open the right destination or plan in the app, and a promo code in the link is already filled in at checkout.
- Your order emails now arrive in the language you use the app in, and the legal pages open in that language too.
- Top-ups that add days rather than data now say so clearly.
- Rate SefereSIM from your Account page.

### 1.0.1 — 2026-08-27
