You’ve just landed, turned off airplane mode, and realized you forgot to arrange mobile data. Can you still buy an eSIM after arriving at your destination?

Yes, in most cases, you can buy and install an eSIM after landing. You’ll simply need a stable Wi-Fi connection, an eSIM-compatible unlocked phone, and a payment method that works internationally.

Here’s what you should know before purchasing one at the airport, hotel, or anywhere else after arrival.

Buying an eSIM after arrival is usually straightforward. Before purchasing, check that:

Airport Wi-Fi may be enough to complete the process, but hotel, café, or accommodation Wi-Fi is often more stable.

The process normally takes only a few steps:

Once your phone connects to a supported local network, you should be able to use mobile data.

If the QR code appears on the same phone you’re using for installation, look for options such as direct installation, manual entry, or opening the QR code on another device.

It depends on the plan.

Some eSIM plans activate as soon as you install them. Others begin only when they connect to a supported network at your destination. This matters because the plan’s validity period may start immediately after installation.

Always check the activation policy before installing. If the plan activates upon installation, purchase it only when you’re ready to use it.

Buying before departure is generally more convenient. You can install the eSIM using your home Wi-Fi and check that everything is set up before your trip.

However, buying after landing can still be useful if:

The main disadvantage is that you’ll depend on airport or hotel Wi-Fi until the eSIM starts working.

You need an internet connection to purchase and download an eSIM profile. If airport Wi-Fi isn’t available, you may need to connect at your hotel, a café, a tourist information center, or another location offering Wi-Fi.

You can also temporarily use international roaming on your regular SIM, but check the charges first. Even a short connection may be expensive, depending on your carrier.

If the eSIM has been installed but you still have no internet, check the following:

Restarting the phone or briefly switching airplane mode on and off may also help it reconnect to the local network.

Do not delete the eSIM while troubleshooting unless the provider tells you to. Many QR codes can only be installed once.

Yes. If your plan runs out, you may be able to top it up or purchase another eSIM online.

Whether you need to install a new eSIM depends on the provider and plan. Some plans support top-ups, while others require a new QR code. Check the instructions before your current data expires so you don’t lose internet access unexpectedly.

Yes, you can normally buy an eSIM after landing as long as your phone is compatible and unlocked, and you have access to Wi-Fi.

Purchasing and installing it before departure is less stressful, but forgetting to do so doesn’t mean you’re stuck without internet. Connect to a reliable Wi-Fi network, choose a suitable Datapang eSIM plan, follow the installation instructions, and you can usually get connected without visiting a SIM card counter.
