eSIM Hungary

An eSIM is a digital SIM built into a compatible device. A travel eSIM lets you add a mobile data plan without replacing your usual physical SIM card.

After purchasing, you receive installation or activation details by email. Once the eSIM is installed and activated according to the supplied instructions, your device can connect to supported mobile networks within the plan's coverage area.

Check the coverage area, data allowance, validity period, activation policy, network information and included services shown on the product page before checkout.

A smaller allowance may suit maps, messaging, email and occasional browsing. Consider more data for regular navigation, social media, video calls, streaming, remote work or hotspot use where the selected plan supports it.

Your phone must include eSIM functionality and normally needs to be carrier-unlocked. Compatibility can vary by model, country of purchase, mobile carrier and software version.

Check the device settings, manufacturer specifications or the EziGo compatible-device guide before purchasing. A carrier-locked device may not accept a travel eSIM from another provider.

The QR code or activation details are normally sent to the email address used at checkout after the order and payment have been completed.

If the email does not arrive, check the spam or junk folder and confirm that the email address entered during checkout is correct before contacting support.

Install the eSIM while you have a stable internet connection, preferably before departure. The correct activation time depends on the selected plan.

Some plans begin when they first connect to a supported network, while others may start after installation or manual activation. Always follow the activation instructions supplied with the order and do not delete the eSIM after installation.

In most cases, you can keep your primary SIM active for your usual phone number while using the travel eSIM for mobile data, provided your device supports dual-SIM operation.

WhatsApp generally continues using the number already registered to the account. Review your device settings carefully because calls, messages or roaming on the primary SIM may create charges from your home carrier.

No. These features depend on the selected plan, destination, available mobile network and compatible device. Some plans support 5G where local coverage is available, while others use 4G or LTE.

Hotspot or tethering may be available only on selected plans. Many travel eSIM products are data-only and do not include a local phone number, voice calls or SMS. Check the current product details before checkout.

After the full data allowance is used, you may need to purchase another suitable plan unless the selected product explicitly supports a top-up or renewal.

Do not delete an installed eSIM unless instructed to do so. If it is deleted accidentally, contact EziGo support with the order number and device model. The support team can review whether the plan and provider allow the configuration to be restored or reissued.

Confirm that the eSIM is enabled for mobile data, select the correct eSIM line and turn on Data Roaming if required by the plan. Restarting the device may help it register on the local network.

Check that you are inside the coverage area and follow any supplied APN or network selection instructions. If the problem continues, contact EziGo support while the issue can still be investigated during the trip.
