What is an eSIM and how does it work?
An eSIM is a digital SIM that’s already built into your device, so there’s no physical SIM card needed.
Just check your device is compatible, choose a plan, and install it instantly. Once you arrive at your destination, your eSIM connects to a local network so you can get online straight away – no SIM swapping or hunting for Wi-Fi.
When should I activate my eSIM?
We recommend installing your eSIM before you travel while connected to Wi-Fi.
It won’t activate until you arrive and connect to a local network. Once you land, simply make sure the eSIM is switched on in your device settings and you’re good to go.
Will I lose my contacts, WhatsApp, or phone number?
No. Everything stays the same – your home SIM, contacts, and apps are unaffected.
What if it doesn’t work when I land?
First, restart your phone – most issues are solved immediately this way.
If needed, follow the simple troubleshooting steps in our Help Centre or contact our 24/7 support team.
I’ve never used an eSIM before. Will it be hard?
Not at all! Most customers are set up in just a few minutes. Step-by-step instructions are provided in your email and the Simify app.
Plus, with our Money Back Guarantee, you’re covered with a full refund if there’s an issue we can’t resolve.
What speeds can I expect?
4G and 5G in most cities and towns; speeds may be slower in remote areas.
Can I buy an eSIM for a friend? How does it work?
Yes! You can send an eSIM to a friend via email through the Simify app under My eSIMs. We also offer discounts when purchasing more than one eSIMs.
Can I top up my eSIM?
Top-ups aren’t available yet, but we’re building this feature. In the meantime, you can repurchase a new eSIM through the app or website and be connected in minutes.
Who are travel eSIMs best for?
Travel eSIMs are perfect for anyone who wants reliable internet while overseas – from holidaymakers and business travellers to digital nomads and frequent flyers.
They help you avoid roaming charges, skip local SIM shops, and stay connected on trusted local networks wherever you go.
Why should I choose an eSIM instead of roaming or a physical SIM?
eSIMs are simpler, more flexible, and often more affordable.
You can keep your home SIM in place, avoid expensive roaming fees, and get online as soon as you land. That means easy navigation, instant messaging, bookings on the go, and staying connected without hassle.
What if my travel plans change?
No worries! Under our 100% Money Back Guarantee, you can request a refund if your trip is cancelled or delayed.

How do I install my eSIM?
- Download the Simify app and log in with your purchase email
- Follow the installation guide under My eSIMs (automatic setup is fastest)
- Turn on your eSIM once you land
Full guides are also available in the Help Centre.
Can I store multiple eSIMs on my device?
Yes. Most devices store multiple eSIMs, though only one can be active for data at a time. Switching is simple via phone settings.
When does my eSIM plan start?
Your plan starts when the eSIM first connects to a local network at your destination. From that moment, your selected number of days begins counting down.
How can I confirm my eSIM is installed correctly?
Check your mobile settings – the eSIM should appear. When you arrive, enable it as your primary data plan, turn on Data Roaming, and restart your device if needed. Support is available anytime if you get stuck!
How do I know if my phone is unlocked?
Most devices are unlocked. If unsure, test with another SIM or contact your carrier. Phones on a plan may require unlocking first.
Are calls and texts included?
Our eSIMs focus on data, which means you can still call and message using apps like WhatsApp, FaceTime, iMessage, Viber, and more! all through your data connection.
If you plan to use traditional calls or texts, you can keep your home SIM switched on alongside the eSIM. In most cases this works automatically, but availability depends on your mobile plan. Your carrier can confirm this for you, and roaming charges may apply while you’re overseas.
Can I receive calls and texts on my home number while overseas?
Yes. You can use your home SIM alongside the eSIM to receive calls and texts as normal.
Most carriers allow this by default, but we recommend checking with your carrier before you travel – especially if you rely on one-time passwords. Incoming texts are usually free, while calls or outgoing messages may incur roaming charges depending on your carrier.
How can I make international calls home?
VOIP apps like Viber are affordable options. Simply add credit and use your eSIM data connection.
How can I call local businesses overseas?
Use VOIP apps like Viber, or contact businesses via WhatsApp or email. Many hotels also provide guest landlines.
Can I keep my WhatsApp number and chats?
Yes, everything stays exactly the same. Your number, contacts, and chat history are preserved automatically.
