Frequently asked questions
Everything you need to know about DataSIM and travel eSIMs.
What is an eSIM and how does it work?
An eSIM (embedded SIM) is a digital SIM card built into your phone — no plastic, no swapping. You install it through an app or QR code, and it acts as a second line on your device. With DataSIM, you buy a data plan for any of 190+ countries, install the eSIM in minutes, and connect to local mobile networks abroad — without removing your home SIM or paying roaming charges.
How is DataSIM different from other eSIM apps?
DataSIM is operated by ZEUST LIMITED, a Cyprus-based telecommunications company with 25+ years in the industry and 6M+ app downloads across its products. Most travel eSIM apps are marketing startups reselling someone else's network — DataSIM comes from inside the telecom industry, with direct carrier relationships, premium network partners, and real 24/7 human support. That shows up in connectivity quality, honest pricing from $0.50/GB, and a team that actually answers when something goes wrong.
Does my phone support eSIM?
Most phones from 2019 onward do. This includes iPhone XS and later, Google Pixel 3 and later, and recent Samsung Galaxy models (S20 and newer). Your phone must be carrier-unlocked. If you're unsure, dial *#06# on your phone — if you see an "EID" number, you have eSIM.
Will I keep my regular phone number?
Yes. A DataSIM eSIM is data-only and runs alongside your existing SIM — your home number stays active for calls and texts, and apps like WhatsApp, iMessage, and FaceTime keep working with your existing number over data. You use the eSIM purely for mobile internet abroad.
How much does a DataSIM eSIM cost?
Prices vary by destination. Plans start as low as $0.50/GB (Turkey), with most popular destinations between $0.80 and $1.30 per GB. All plans are valid 30 days, prepaid, with no contracts or hidden fees. You can see live prices for every country in the DataSIM app or on each country page.
When should I install my eSIM — before or after my trip?
Install it before you travel, while you're still on Wi-Fi at home. Your plan doesn't start counting until the eSIM connects to a network at your destination, so installing early costs nothing and saves you from setting it up at the airport with no internet.
What happens when my data runs out or my plan expires?
Top up instantly in the DataSIM app — no need to install a new eSIM or buy a new package. The app tracks your remaining data and shows you when to renew. If you don't top up, your eSIM simply stops using data; it doesn't charge you anything else.
Is DataSIM safe and reliable?
Yes. DataSIM is operated by ZEUST LIMITED, a regulated EU telecom company registered in Cyprus (Reg. No. HE 362856), operating mobile communication products since 2016. Payments are processed securely, and support is available 24/7 at support@data-sim.app.
