What is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your device. There's no physical card to insert: you simply scan a QR code we send by email to activate your data plan instantly.
How does it work?
It's simple:
1. Choose your plan: Unlimited Max, Unlimited Pro (1-30 days) or 100, 200 or 400 GB
2. Enter your e-mail and phone number (for the 100 GB plan also your phone's IMEI), tick the box for immediate delivery and pay securely with Stripe (card, Apple Pay or Google Pay)
3. Receive your eSIM QR code by e-mail within minutes, with the link to the eSIM install guide. If your number uses WhatsApp, you also get the install guide link there
4. Connect to Wi-Fi and scan the QR code to install the eSIM
5. Choose the eSIM line for mobile data, turn on data roaming for it and enjoy fast internet across Europe. It usually connects by itself. Only if the internet does not start, set the APN from your order e-mail (for plans that have APN settings)
Which plans do you offer?
Our plans are eSIMs for Europe covering 38 to 46 countries, depending on the plan (the exact list is in each plan's details):
• Unlimited Max: unlimited data at maximum 5G/4G+ speed for 30 days, hotspot included
• Unlimited Pro: 1 to 30 days of unlimited data, 2 GB per day at full 4G/5G speed, then up to 10 Mbps until the daily reset; it is the only plan that also covers Turkey
• 400 GB and 200 GB: 30 days at maximum speed, data only. On the 200 GB plan the validity starts at the moment of purchase
• 100 GB: 30 days at maximum speed, plus a French phone number (+33) for calls and SMS; at checkout you enter your phone's IMEI (dial *#06# to see it)
Apart from the 100 GB plan, the plans are data-only and don't include a phone number, so keep your usual SIM for calls and SMS. Prices and the full details of each plan are shown on the plans page before you buy.
Is the 1-day plan really free?
Yes. Unlimited Pro for 1 day is free for our first 100 customers, while the plans page still shows free places left. No card is needed.
Conditions:
• one free eSIM per person: per e-mail address, per phone number and per internet connection (IP address)
• a valid mobile phone number is required
• it can't be combined with promo codes and can't be topped up
• it has no cash value and can't be exchanged or transferred
The installation details (QR code) are sent only by e-mail (and on WhatsApp, if your number uses WhatsApp), so make sure your e-mail address is correct.
When the free places are used up, the 1-day plan is sold at its regular price. The full conditions are in the Terms & Conditions.
When should I install it?
Install the eSIM as soon as you receive it, while you are connected to Wi-Fi (or to mobile data on your usual SIM), for example before you leave home or during a break.
The QR code can be used only once, so keep the eSIM on your phone. On Unlimited Max, Unlimited Pro, 400 GB and 100 GB the validity is counted from activation; on the 200 GB plan it starts at the moment of purchase, so buy it on the day you leave.
How fast will I receive it?
Usually within a few minutes after your payment is confirmed. You receive:
• an e-mail with the QR code, the details for manual installation and the link to the eSIM install guide (plus the APN settings, if your plan needs them)
• access to your order page, with the same details
• on WhatsApp, if the phone number in your order uses WhatsApp: the link to the install guide
For the free 1-day plan, the installation details are sent only by e-mail (and on WhatsApp); the page shown after your claim displays only the status of your order.
In rare cases preparing the eSIM takes a little longer; we e-mail you as soon as it is ready. Don't see the e-mail? Check your spam/junk folder and make sure the e-mail address in your order is correct.
What do I get on WhatsApp?
If the phone number in your order uses WhatsApp, as soon as your eSIM is ready Flash Sim sends you a WhatsApp message with the link to the install guide for your phone (iPhone or Android) and the link to your order. If your plan needs APN settings, the message includes them too.
The e-mail with your QR code is always sent as well, so you don't need WhatsApp to install the eSIM. No message? Check that the phone number in your order uses WhatsApp.
These are service messages about your order, never advertising. To stop them at any time, reply STOP or write to us; we stop sending them at the latest within 1 business day.
Which countries are covered?
Our plans cover 38 to 46 European countries, including the United Kingdom and Switzerland:
• Unlimited Pro: 46 countries, including Turkey
• 100 GB: 42 countries
• 200 GB: 41 countries
• Unlimited Max: 38 countries
• 500 GB and 400 GB: 38 countries
Unlimited Max and the GB plans do not include Turkey. The exact list of countries is on each plan card, under Details, before you buy.
Can I top up or extend my plan?
Yes. On the Recharge page you add a new plan to the same eSIM, with no new QR code: enter the eSIM's ICCID and the e-mail address of your order, and we check right away which packages can be added to it. Then choose the package, at the same prices as on the website.
The added plan has its own validity. If your eSIM cannot be topped up, we tell you straight away and you can buy a new eSIM. Don't delete the eSIM from your phone, so you can top it up.
Can I use hotspot / tethering?
Yes. Hotspot is included in all our plans: share your connection with your laptop, tablet or other devices in the cab.
Data used through the hotspot counts towards your plan. On Unlimited Pro the daily 2 GB at maximum speed (and after them the speed of up to 10 Mbps) are shared by all connected devices.
What speed / network will I get?
• Unlimited Max: unlimited data at the highest speed available in the network (5G/4G+), for 30 days.
• The 100, 200 and 400 GB plans: all the data at the highest speed available in the network (5G/4G+).
• Unlimited Pro: unlimited data, each day 2 GB at maximum speed (4G/5G), then up to 10 Mbps until the daily reset (every 24 hours from first use). At 10 Mbps GPS navigation, messaging, video calls and HD video work smoothly.
Actual speed depends on coverage, network load and your phone. On the GB plans, data stops when the data volume is used up; you can then add a new plan to the same eSIM on the Recharge page.
What payment methods do you accept?
Payments are processed securely by Stripe. You can pay with:
• Visa, Mastercard and American Express cards (credit or debit)
• Apple Pay or Google Pay, if your phone or browser offers them
The payment page may also show other methods available for your country or device. Prices are in euro (EUR) and include VAT where applicable. You enter your card details on Stripe's secure page; they are never stored on our servers. PayPal is not available.
Can I get a refund?
• Before you install or activate the eSIM: you can withdraw within 14 days of purchase and get a full refund.
• After installation or activation: at checkout you ticked the box asking for immediate delivery and confirming that your right of withdrawal ends once the eSIM is installed or activated. From then on the 14-day withdrawal no longer applies; you still get a full refund if the eSIM doesn't work because of a technical problem on our side that we can't fix, and your legal rights for a faulty service always remain.
Refunds go back to your original payment method through Stripe; your bank may need a few business days to show them. The free 1-day plan has no refund, as nothing was paid.
To ask for a refund, open a support request with your order number or ICCID. The full details are in our Refund Policy.
My eSIM is not working
Try these steps:
1. Turn on Data Roaming for the eSIM line
2. Choose the eSIM as the line for mobile data
3. Check that airplane mode is off, then restart your phone
4. Make sure you are in a country covered by your plan and wait a few minutes for the network to register
5. Only if the internet still doesn't work, set the APN exactly as shown in your order e-mail (for plans that have APN settings)
Still not working? Open a support request on the Support page. No account needed, just your ICCID plus the e-mail address or phone number of your order.
Can I get support without an account?
Yes. On the Support page, open a request for an eSIM you bought from us and enter:
• the ICCID of your eSIM
• the e-mail address or the phone number used for the order
We check these details against your order, so we can help you straight away, with no password. Our replies are sent to the e-mail address of your order. Later you can check the status of your request with its reference number (FS-…).
Where do I find the ICCID of my eSIM?
The ICCID is the unique number of your eSIM: it starts with 89 and usually has 19-20 digits.
You can find it:
• in the e-mail with your eSIM and on your order page
• on iPhone: Settings → General → About, under the eSIM line
• on Android: Settings → About phone → SIM status (menu names vary by brand)
Can I have multiple eSIMs?
Yes! Most eSIM devices can store multiple eSIM profiles. You can keep your home SIM active for calls/texts while using your Flash Sim data plan for internet.
Only one profile can be the active data line at a time, but switching between them is quick and easy in Settings.
How can I contact support?
You can reach us:
• in the chat on our website: tap "Talk to a person"
• with a support request on the Support page, no account needed: your ICCID plus the e-mail address or phone number of your order or, for any other question, your e-mail address (and your order number, if you have one)
• by e-mail: suport@flashsim.com
Please include your order number or ICCID and your phone model. We are available non-stop (24/7) and usually answer within a few hours.
