A Hungary eSIM lets a compatible, unlocked Android phone connect to mobile data without swapping the physical SIM. You can install the plan before departure, keep your usual number available and select the Hungary line for data after arrival.
Android menus vary by manufacturer, model, region and software version. Google Pixel and Samsung Galaxy use different labels, while Motorola, Xiaomi, Honor and other brands may place eSIM controls elsewhere. Confirm the exact device rather than assuming every phone with the same marketing name supports eSIM.
NoveSIM travel eSIM plans are data-only. They normally do not include a Hungarian number, traditional calls or SMS. WhatsApp, Messenger, maps, email and internet calling work through mobile data.
Quick answer: On Google Pixel, open Settings > Network & internet > SIMs > Add SIM > Set up an eSIM. On Samsung Galaxy, open Settings > Connections > SIM manager > Add eSIM. Scan the plan’s QR code over reliable Wi-Fi, label the line Hungary eSIM, select it for mobile data and follow the provider’s roaming instruction. Disable automatic data switching to protect your home SIM from roaming charges.

Support depends on the exact model and sales region. Many recent Google Pixel and Samsung Galaxy flagships support eSIM, but lower-cost models and some regional variants do not. Carrier firmware can also affect availability.
On Pixel, look for Add SIM and Set up an eSIM under Network & internet. On Galaxy, look for Add eSIM in SIM manager. You can also search Settings for “eSIM.”
An EID under Settings > About phone is another useful signal. The EID is an identifier for the embedded SIM. If the menu and EID are missing, confirm the model number with the manufacturer.

Google Pixel eSIM Support
Google states that Pixel 4 and later models generally support eSIM, while older Pixel 2, Pixel 3 and Pixel 3a variants have carrier and regional limitations. Current US Pixel 10, Pixel 10 Pro and Pixel 10 Pro XL models are eSIM-only.
Pixel 7 and later can support two active eSIM profiles when the carrier allows it. This is useful for travellers who already use an eSIM as their home line, but mobile data still comes from one selected line at a time.
How to Install on Google Pixel
- Connect the phone to reliable Wi-Fi.
- Open Settings.
- Tap Network & internet.
- Tap SIMs.
- Tap Add SIM.
- Choose Set up an eSIM.
- Scan the QR code or follow the manual setup option.
- Label the plan Hungary eSIM.
Menu wording can differ slightly by Android version. If the QR code is displayed on the Pixel itself, open it on another screen or use the provider’s direct installation or manual details.
Samsung Galaxy eSIM Support
Many recent Galaxy S, Z Fold and Z Flip models support eSIM, along with selected devices from other Galaxy lines. Support varies by country and carrier. Two phones with the same series name can have different eSIM capabilities.
Samsung lists QR scanning, manual entry and carrier-supported simple setup as possible installation methods. A travel provider commonly supplies a QR code.
How to Install on Samsung Galaxy
- Connect to stable Wi-Fi.
- Open Settings.
- Tap Connections.
- Tap SIM manager.
- Tap Add eSIM.
- Choose Scan QR code.
- Scan the provider’s code and confirm the download.
- Rename the plan Hungary eSIM.
Restart the Galaxy after installation if the new plan does not appear correctly. Do not remove the profile merely because it has not yet connected outside Hungary.
Other Android Brands
Motorola, Xiaomi, Honor, Sony and other manufacturers use different menu paths. Search Settings for “SIM,” “mobile network” or “eSIM.” Consult the manufacturer’s documentation for the exact model number and country version.
Do not rely on a generic compatibility list alone. Some regional devices omit eSIM hardware or firmware even when another version of the same phone supports it.
When to Install the Hungary eSIM
Install before travel over reliable home Wi-Fi. Save the QR code, manual activation values and support instructions offline. Read the validity rule first: some plans begin when installed, while others begin at the first connection to a supported Hungarian network.
Installation and network activation are separate events. A profile can be present but show no service before you reach Hungary. This is normal when the plan is destination-specific.
Dual SIM Settings for Travel
Keep the home line enabled if you need incoming verification SMS. Select Hungary eSIM as the preferred mobile-data line. Disable automatic data switching, backup calling data or similar features that could let the home SIM use roaming data.
Turn off data roaming on the home line. On the Hungary line, follow the travel provider’s instruction. Many international eSIMs require roaming to be enabled because the profile connects through a partner network.
Pixel may label the setting Mobile data or Use SIM. Samsung may show preferred SIM controls inside SIM manager. Verify the selected line before opening a high-data app.
How to Activate After Arrival
- Open the phone’s SIM or mobile-network settings.
- Turn on Hungary eSIM.
- Select it for mobile data.
- Enable roaming only when instructed for the travel line.
- Keep the home line’s data roaming off.
- Use automatic network selection.
- Toggle airplane mode or restart the phone.
The plan may connect through Telekom, Yettel or One depending on its partner agreement. It may not support all three networks. See mobile networks in Hungary and Telekom vs Yettel vs One Hungary.
WhatsApp, Calls and SMS
WhatsApp normally keeps the number already registered in the app. A data-only eSIM does not require changing it. Telegram, Signal, Messenger and other internet apps also use the travel data connection.
Traditional calls and SMS usually remain on the home line unless the travel plan includes a local number. Your home operator may charge for calls or outgoing SMS in Hungary. Check its roaming tariff before use.
Reduce Data Usage
Android can consume data through photo backup, Play Store updates, video autoplay and background sync. Turn on Data Saver, restrict cloud backup on mobile networks and download offline maps over Wi-Fi.
Hotspot use can consume a large allowance quickly. Confirm that tethering is permitted, then monitor usage in the phone’s network settings or provider dashboard.
Troubleshooting
The Add eSIM Option Is Missing
Confirm the exact model and region, install supported system updates and search Settings. Carrier-locked or regional firmware can hide eSIM features.
The QR Code Will Not Scan
Increase the brightness of the second screen, clean the camera lens and use manual activation details if supplied. Check whether the code was already used.
The eSIM Shows No Service
Make sure the line is on, the phone is in Hungary and the plan is within its activation window. Enable the required roaming setting and restart.
There Is Signal but No Data
Select Hungary eSIM as the mobile-data line, check the allowance and verify the official APN. Toggle airplane mode and return to automatic network selection.
The Connection Is Slow
Move outdoors or near a window, switch between 5G and LTE and test another location. Congestion and indoor construction can affect speed.
Do Not Delete the eSIM First
Deletion is a last resort. Many QR codes are single-use. First restart the phone, toggle the profile, check the data line, roaming, APN and network selection, then contact support.
Before Returning Home
- Select the home SIM for mobile data.
- Turn the home line fully on.
- Turn off the Hungary eSIM.
- Keep or remove it according to the plan’s reuse rules.
- Confirm home-network service before leaving Wi-Fi.
