What usually happens instead
The roaming pack
Roaming packs work. You just pay a lot for the same antennas, and the number turns up on a bill after the trip.
The SIM counter after you land
A local SIM works too, when the shop is open, the queue is short, and your phone still takes a plastic card.
An eSIM uses those same local networks. The difference is that you arrange it at home, at a price you agreed to before you left.

No tricks
We do not refund a plan once it has been used. The one exception is an eSIM that never activated or does not work, and we sort that out by email at support@seferesim.com.
One payment in US dollars, with no fee added at the end. If your card is in another currency, your bank sets the rate.
If the phone you tell us about cannot take an eSIM, we say so and sell you nothing.

Travelling often?
Some plans are also sold as subscriptions, daily passes included. A subscription renews on its own every 7 or 30 days until you cancel, you can cancel at any time, and a cancelled plan runs to the end of the period you have already paid for.

Why 'SefereSIM'
In Turkish, a journey is a sefer. The word traveled here itself: it comes from the Arabic safar, the same root that gave the world safari. Every language that borrowed it kept the same meaning: setting out.
Turkish has a word for the person who has set out, too: seferi. Being seferi once meant the road recognized you. Custom lightened your load: the traveler was excused, hosted, helped onward. That is the oldest deal in travel: the one in motion deserves ease.
SefereSIM is that deal, continued. Say the name aloud: sefere SIM, a SIM for the journey. Listen again and it says seferi SIM: the traveler's SIM. Both are true. You set out; connection is already handled. No roaming bill waiting at home, no kiosk hunt at the airport, no contract. You land connected, because you are seferi, and the road still owes you lightness.
Questions people ask
- Will this work on my phone?
- It needs a phone that takes an eSIM. Recent iPhones and most flagship Android phones do, though iPhones bought in mainland China do not. We ask which phone you have before you pay.
- When does the plan start?
- When the eSIM first connects to a network at your destination, not when you buy it. Buying a few days early costs you nothing.
- Do I keep my own number?
- Yes. The eSIM is a second line, for data. Calls and texts stay on your usual SIM, and you can leave its data switched off while you travel.
- Can I move it to another phone?
- No. An eSIM installs on one phone only, and deleting it from that phone uses it up for good. Put it on the phone you will actually be travelling with.
- Can I use a hotspot or tether another device?
- Hotspot sharing is supported on compatible devices. Devices you connect share the same plan allowance and any fair-use limits. Availability also depends on device settings. If your eSIM includes APN details, use exactly those details, or contact support@seferesim.com if sharing does not work.
