Frequently asked questions

Instantly: seconds after payment your eSIM lands in your inbox with its QR code. Order through the Blitz app and you'll also find it right away under your orders. Nothing received? Check your spam or promotions folder.

No. A Blitz eSIM is prepaid: you pay once for your data plan and that's it. No subscription, no cancellation period and no charges afterwards.

You pay securely via Stripe with credit card, Apple Pay, Google Pay, PayPal or Klarna, among others. The available methods are shown at checkout.

Yes, up to 10 per order — handy when you're travelling together. Each eSIM has its own QR code and is installed on one device.

First check your spam or promotions folder; the email is sent right after payment. Your eSIM is also always available in the Blitz app under your orders. Still nothing? Contact support and keep your order number handy.

Scan the QR code from your email: go to Settings → Add SIM on your phone and follow the steps. Done in a couple of minutes — no physical SIM swapping required.

We recommend it: install at home over Wi-Fi so you're online the moment you land. Only switch on the eSIM's data roaming at your destination — your plan doesn't start until the first connection, so installing costs you no days.

Most devices from recent years are: iPhone XS or newer, recent Samsung Galaxy and Google Pixel models. Not sure? Dial *#06# in the phone app — if you see an EID number, your device supports eSIM.

No, an eSIM belongs to one device. Travelling with several devices or people? Order a separate eSIM per device (up to 10 per order).

Only the moment your eSIM first connects to a network at your destination. Installing at home in advance costs you no days of your plan.

Yes. Feel free to share your data via your phone's personal hotspot — with your laptop or travel buddy, for example. The usage simply comes out of your plan.

No. A carrier-locked phone won't accept an eSIM from another provider. Check with your carrier first — most phones sold after 2021 are unlocked.

You get a fixed amount of full-speed data each day (shown with the package). After that you stay online at a reduced speed until the next day — plenty for messaging, mail and maps.

Yes. The eSIM only handles your mobile data; your regular number and WhatsApp keep working exactly as you're used to.

A Blitz eSIM is a data plan. Calls and messages go through apps like WhatsApp or FaceTime — that simply runs on your data. Your own SIM stays active alongside it for your regular number.

In the Blitz app you follow your usage live per eSIM, and you get a heads-up before your data runs out. Note: depending on the local network, usage can lag 1 to 3 hours behind.

You have 180 days after purchase to activate your eSIM. So ordering well ahead of your trip is fine — your plan's validity only starts at the first connection at your destination.

It varies per plan; the validity in days is shown with every plan in the shop. The days only start counting once your eSIM first connects at your destination.

Top up your eSIM in the Blitz app: open your eSIM, choose 'Top up data' and pay. Your new plan is added as soon as the provider confirms — no new QR code or installation needed.

The plan simply stops; nothing keeps charging and you're not tied to anything. Through the app you buy a new plan for your next trip in two taps.

Everything in one place: order and install eSIMs, follow your usage live, top up data in two taps and get a heads-up before your data runs out or your plan expires. Plus you earn Volts automatically.

Volts are our rewards credit: with every order you automatically get a percentage back in Volts, which you use as a discount on your next plan. You also earn Volts by inviting friends.

There are three levels: Spark, Bolt and Blitz. The more Volts you earn in total, the higher your level — and the higher the percentage you get back on every order, up to 10%.

You can order without an account, using just your email address. In the app you sign in with a code sent to your email (no password) — then you'll see your eSIMs, orders and Volts in one place.

Yes. All payments run through payment provider Stripe; Blitz never stores your payment details. You pay with credit card, Apple Pay, Google Pay, PayPal or Klarna, among others.

An eSIM is a digital product: once the QR code has been delivered, the right of withdrawal lapses. If your eSIM demonstrably doesn't work due to a technical delivery issue, we'll review a refund — contact support. The full rules are in our terms and conditions.

Usually nothing was charged and you can simply try again, possibly with a different payment method. Money charged but no eSIM delivered? Contact support and include your transaction ID or order number.
