“Unlimited data removed the anxiety of staying connected on the go!”

Skiers in helmets and goggles with red lenses

We used this eSIM for our trip to Japan and found it easy to install, activate and use. We had great coverage everywhere we went and were able to stay in contact with family and friends. Would recommend this eSIM for all your travel needs.

Loved the Simify eSIM - made keeping in contact with family at home so easy. And had lots of data to upload photos. We will definitely use it again!

Setting up the eSIM was simple, following the instructions provided. Having the eSIM gave me peace of mind, knowing that I could use Google Maps to find my way back to the hotel and to use Google Translate.

Frequently Asked Questions

  • About our eSIMs
  • First-Time Users
  • General
  • Setup & Support
  • Calls & Texts

What network will I connect to?

Your eSIM automatically connects to the strongest available network in your area, so you get the best possible coverage and speeds wherever you are.


If signal conditions change, it can seamlessly switch networks in the background to keep you connected.

How far in advance can I buy my eSIM?

Up to 6 months before your trip. Start plan within 6 months of purchase – your plan duration starts once connected to a local network.

How soon will I receive my eSIM?

Right away.

Your eSIM is delivered instantly by email after purchase and is ready to install via the Simify app.

Does this eSIM replace my home SIM?

No – and that’s one of the best parts!

Your eSIM works alongside your home SIM. Most travellers use the eSIM for data and keep their home SIM active for calls, texts, and one-time passwords. You stay connected without giving up your number.

Just make sure Data Roaming is turned off on your home SIM if you want to avoid roaming charges for outgoing calls or texts.

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.

Quick tips for peace of mind:

  • Check your device is eSIM-compatible. Click here

  • Make sure your phone is unlocked

  • Keep the Simify app handy

You’re covered by our Money Back Guarantee for a full refund if there’s an unsolvable issue

How do I install my eSIM?

  1. Download the Simify app and log in with your purchase email

  2. Follow the installation guide under My eSIMs (automatic setup is fastest)

  3. 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.
