SefereSIM is a travel eSIM store. Pick where you are going, pay, and your QR code arrives by email within a couple of minutes. Scan it once and your phone is online before you land. WHAT YOU GET - Data plans for 190+ destinations, from single countries to regional bundles for Europe, Asia and the Middle East. - Your QR code by email once payment clears, with a copy kept inside the app. - Every plan you have bought in one place, with the data you have left on each one. - The full price on screen before you pay. The number at checkout is the number charged. - When a plan runs out, the data stops. No overage, no surprise bill waiting at home. HOW IT WORKS 1. Choose your destination and the amount of data you want. 2. Pay with Apple Pay or a card. 3. Open the email, scan the QR code, and turn the line on when you arrive. WHY TRAVELERS USE IT Roaming charges from a home carrier are hard to predict before a trip. A prepaid travel eSIM is not: you buy a set amount of data for a set number of days, and that is the whole arrangement. Your usual number stays active for calls and texts, and SefereSIM carries the cellular data. PREMIUM PLANS In Turkiye, Canada and Laos, Premium plans run on selected local networks. They are there for people who want a specific network rather than whichever route the standard plan uses. BEFORE YOU BUY Your iPhone needs to support eSIM and be carrier unlocked. iPhone XS and later support eSIM. If you are not sure about the lock status, ask your carrier first. The app is available in English and Turkish.
