AskHeidi eSIM is a digital-first mobile data provider powered by the Airalo Partners Network. We resell over 3,200 high-speed data plans across 200+ countries and territories. Instead of swapping a physical SIM card, you scan a QR code to instantly download a data pack to your phone's eSIM chip.
Prices vary by destination, but AskHeidi is generally far cheaper than traditional carrier roaming. For example, a 21-day regional plan for Europe costs around $15 through AskHeidi, compared to roughly $10 per day for standard US-carrier roaming — saving travelers approximately 93% on a three-week trip.
AskHeidi offers a 30-day money-back guarantee for eSIM plans that have not been downloaded or activated. Once an eSIM has been activated and data has been transmitted, the plan is non-refundable. Contact support@askheidi.app to request a refund.
AskHeidi eSIMs work natively with most modern, unlocked smartphones. Supported devices include the Apple iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. Use our Device Check tool to verify your specific model.
Delivery is instant via email upon purchase, and the physical activation process takes under 2 minutes. There is no store visit, shipping, or physical SIM swap required — scan the QR code in your phone's cellular settings and you're connected.
Yes. You can use your phone's dual-SIM capability to keep your primary physical SIM active for calls and SMS, while designating your AskHeidi eSIM purely for mobile data. WhatsApp and other messaging apps run normally over the data connection.
Because AskHeidi is powered by the Airalo Partners Network, you automatically connect to premium local carriers. For example, a Japan eSIM connects to NTT DOCOMO's 5G NR network, capable of typical speeds around 142 Mbps.
AskHeidi sends proactive push notifications when you reach 80% and 100% of your data usage. This lets you top up your plan before you lose connectivity.
A single-country plan (for example, a Japan eSIM) works only in that specific country. AskHeidi also offers regional hubs (Europe, Asia, the Americas and more) and a global plan that covers multiple countries on a single eSIM without needing to switch.
First, ensure that Data Roaming is toggled ON in your device settings for the AskHeidi eSIM line. If it still does not connect, you may need to manually update your APN (Access Point Name) settings — contact support@askheidi.app and we'll walk you through it.
Install 1–2 days before you travel — you'll need Wi-Fi to complete setup. The plan's validity period begins when the eSIM first connects to a local network at your destination, not when you install it.
“Used it in Switzerland for 2 weeks. Setup took literally 1 minute at the airport. Flawless 5G the entire trip.”
“The UI is so clean and it just works. I love the data usage notifications, kept me from running out while navigating Tokyo.”
“Compared to my carrier's $10/day pass, this was a steal. Paid $15 for my whole Europe trip. Speeds were top tier.”
