Lightning data

I was surprised how fast the internet was. I had pocket WiFi before and it was not this fast.

Can’t sign in with express vpn

Every time I try and log in with express vpn, it just goes to a white screen and crashes. Then it says Failed to verify authentication token. Useless app.

Response from developer

Hello Gemm23, We are very sorry to hear about the white screen crash and the authentication token verification error you experienced when trying to log in. We understand how frustrating this can be, and we want to help you get this resolved so you can smoothly manage your eSIM and travel with peace of mind. This issue typically occurs due to our security verification system (powered by Cloudflare), which is designed to protect our platform. When accessing the app while connected to a VPN, the security system may trigger an automated bot check that blocks the login token, occasionally causing the login screen to turn white or crash. To resolve this issue and log in successfully, we recommend trying the following troubleshooting steps: - Temporarily disconnect your VPN: Disconnect your VPN connection just for a moment to complete the login or verification process in the app. Once you are successfully logged in, you can turn your VPN back on to continue browsing with enhanced privacy. - Change your VPN server or protocol: If you prefer to keep your VPN connected, try switching to a different VPN server location or change your protocol to Lightway. This assigns a fresh IP address, which can help you complete the security check smoothly. - Check browser settings: Ensure that both cookies and JavaScript are enabled in your device's default browser settings, as these are required for the security verification to complete successfully. - Reinstall the Holiday.com app: A fresh installation can clear any cached files or temporary session conflicts that might be causing the crash. If you still run into any trouble, please reach out to our support team. We are available 24/7 to help you troubleshoot your connection and boost your online safety. You can contact us by email at support@holiday.com. The Holiday.com Team

Great offer - but be careful not to start the plan by mistake

The app launched the eSIM installation, but this also triggered a question whether to activate (turn on) the eSIM. Just don’t activate it unless you want your plan period to start running. Maybe this is only an issue when you are already in an “activatable” foreign country, but the documentation is not clear, so better to stay on the safe side.

Contrary to some other providers, you can just activate the eSIM on arrival without needing WiFi there

EDIT: I have to remove one star because on my 4G phone in UK, I can only get LTE

Working fine

The service has been working fine since I connected in France. Works much better in the metro areas

eSIM number

I downloaded the app and it prompted me to install eSIM on my phone before I could purchase a data plan and the installation was successful but wasn’t allocated a number how do I go about it please

Response from developer

Hi Freshrex1! Thank you for your review. Please note that the holiday.com eSIM is a data-only service designed to provide you with internet access. Because it focuses on providing a data plan, it does not come with an allocated phone number for traditional voice calls or SMS texts. If your data is working successfully, you are all set! If you need help activating your data or have any other questions, please reach out to us at support@holiday.com. The Holiday.com Team
