A Realistic Timeline for Getting Connected in a New Country
Here's the Short Answer
In most cases, activating an eSIM takes less than 10 minutes.
If you've already purchased your plan and your phone supports eSIM, the process is usually as simple as scanning a QR code, following a few prompts and turning on your new data plan when you arrive.
A typical timeline looks like this:
-
Buy your eSIM: 2 to 5 minutes
-
Install the eSIM: 2 to 3 minutes
-
Activate it after landing: 1 to 2 minutes
-
Connect to the local network: Usually within a minute
Most travellers are online before they've even collected their luggage.
The key is to set everything up before your flight so you're ready to connect the moment you arrive.
eSIM Activation: How Long Does It Actually Take?
One of the biggest questions people have before buying an eSIM is surprisingly simple.
How long does it actually take to activate?
If you've never used one before, it's easy to assume the setup will be complicated.
In reality, it's usually much quicker than buying a local SIM card or relying on international roaming.
For most travellers, the entire process takes less than ten minutes.
Here's what you can expect from start to finish.
Before You Start
There are two things you'll need before activating an eSIM.
An eSIM-compatible phone
Most modern smartphones support eSIM, including recent iPhones, Google Pixel devices and many Samsung Galaxy models.
If you're unsure, check your phone's settings or the manufacturer's website before buying a plan.
An unlocked phone
If your device is locked to a specific mobile carrier, you may not be able to use another provider's eSIM.
It's worth checking this before your trip.
Doing these two checks ahead of time saves a lot of frustration later.

Step 1: Buying Your eSIM
Typical time: 2 to 5 minutes
Buying an eSIM is much like making any other online purchase.
Choose:
-
Your destination
-
How much data you need
-
How long you'll be travelling
After payment, you'll normally receive your activation details almost immediately.
If you're using RoamEZY, your installation instructions are sent straight away, so you can get everything ready before you leave home.
Step 2: Installing the eSIM
Typical time: 2 to 3 minutes
Once you've received your QR code or activation details, it's time to install your eSIM.
On most phones, the process looks something like this:
-
Open your mobile network settings.
-
Add a new eSIM.
-
Scan the QR code.
-
Follow the on-screen instructions.
That's usually it.
Installing the eSIM doesn't necessarily activate your data plan straight away.
Many travel eSIMs only begin once you connect in your destination, which is ideal because you're not wasting days before your trip even starts.

Step 3: Landing in Your Destination
Typical time: 1 to 2 minutes
Once you've arrived, all that's left is switching your eSIM on.
Depending on your phone, you may need to:
-
Enable the eSIM
-
Turn on mobile data for that plan
-
Turn off data roaming on your home SIM if required
Your phone will then search for a supported local network.
In most cases, you'll be connected within a minute.
How Long Does It Take to Connect to a Local Network?
Usually, not very long.
Once your eSIM is active, your phone automatically connects to one of the supported local networks.
Most travellers are online almost immediately.
Occasionally, it can take a few extra minutes if:
-
Your phone needs to restart
-
Network registration is still processing
-
You're in an area with weaker coverage
Waiting five to ten minutes isn't unusual, but anything significantly longer may be worth troubleshooting.
Why Some eSIM Activations Take Longer
Most activations are quick, but there are a few situations that can slow things down.
Your phone isn't compatible
This is one of the most common issues.
Always check compatibility before purchasing your eSIM.
Your phone is carrier locked
If your mobile provider has locked your phone, it may reject other eSIMs.
You'll need to contact your carrier to unlock the device.
Poor internet connection during setup
You need an internet connection to download the eSIM profile.
Installing it over a stable Wi-Fi connection before travelling is usually the easiest option.
Incorrect installation
Scanning the wrong QR code or accidentally deleting your eSIM profile can delay the process.
Take your time during setup and follow your provider's instructions carefully.
Should You Activate Your eSIM Before You Travel?
In most cases, yes.
Installing your eSIM before your flight makes life much easier.
You won't be trying to figure everything out after a long journey or while standing in an airport looking for Wi-Fi.
Many travel eSIMs let you install the profile in advance while only activating your plan once you arrive.
That gives you the best of both worlds.
What If Your eSIM Doesn't Work Straight Away?
Don't panic.
Most problems have simple solutions.
Work through this checklist.
-
Restart your phone.
-
Check that your eSIM is enabled.
-
Make sure mobile data is assigned to your eSIM.
-
Confirm you've arrived in a supported country.
-
Enable data roaming if your provider requires it.
-
Check your provider's setup guide.
Most issues are resolved within a few minutes.
If not, contact your provider's support team.
This is where choosing a company with responsive customer service really matters.
Is an eSIM Faster Than Buying a Local SIM?
For most travellers, yes.
Think about the alternative.
After landing, you'd need to:
-
Find a mobile shop
-
Wait in line
-
Show identification if required
-
Buy a SIM card
-
Insert it into your phone
-
Configure your settings
An eSIM removes almost all of those steps.
If you've installed it before your flight, you'll often be connected before you even leave the airport.

For most travellers, less than ten minutes from start to finish.
If you prepare before your trip, you'll probably spend more time waiting for your luggage than waiting for your phone to connect.
That's one of the biggest advantages of using an eSIM.
Instead of wasting time looking for a local SIM card after you land, you can get online almost immediately and get on with enjoying your trip.
