Meet Lempart Flex
The speed you need. A price you love
Affordable unlimited data abroad, with a choice of speed that fits the way you use your phone.
A choice worth having
Your trip is yours. Your data should fit
Roaming is priced to punish you for forgetting to switch it off, and most travel eSIMs are sold as one package at one price. We think a traveller should see the whole shelf and the whole price, and decide for themselves.
Every plan is priced the same way, wherever in the world you are buying from, and the price does not move with the season, the device you are holding, or how many times you have looked at it. No surge pricing, and no discount that is really yesterday’s price.
Every unlimited plan
Built around real life
Your hotel is still out there
Your phone updates. Your trip continues.
An app update or a photo backup can use data you never planned to spend. On a capped package, that can leave you buying more before you can book a ride or contact your hotel. An unlimited-data plan keeps data available for the rest of your plan, even after the daily high-speed allowance is used.

Unlimited data
Stop counting gigabytes. Keep using data after your daily full-speed allowance.
Your kind of speed
Choose Basic for everyday essentials or Enhanced for more room to stream.
Your own number keeps working
The data runs on the eSIM; your usual SIM stays in the phone for calls and messages, so anyone who rings your number still reaches you.

What we believe
We sell what you need, not what we need to sell
The cheapest plan that covers your trip sits on the same shelf as the dearest one, and it is marked when it is the better deal. We would rather you came back next trip than spent more on this one.
The price you see is the price charged
Every price is in US dollars and shown in full before you pay: no activation fee, no card surcharge, and no "from" price that becomes something else at the checkout.
We do not follow you around
Buying needs no account and no name. We do not sell or share personal data, and we ask for as little of it as a purchase can be made with — the email address is optional.
A person answers
Support is a human being reading what you wrote, usually within one working day. No phone tree, and no chatbot pretending to be somebody.

What we offer
Unlimited data is our main focus, and Pro Store gives you more ways to choose. Browse fixed-data packages and unlimited plans with different daily high-speed allowances, durations, coverage, and available speed options. Pick the combination that fits your trip and your budget.
No account. No name asked.
No registration, no app, no profile. The email address is optional: pay, and the eSIM is on the next page. If you do give one, the QR code arrives there as well.
Pay the way you already pay
Card, Apple Pay, Google Pay, Klarna, Cash App Pay, Amazon Pay or cryptocurrency — whichever of these your country and device support. The price you see is the price you pay.
Single countries, regional bundles for trips that cross borders, and plans you can buy for somebody else. Data only: plans do not include a phone number, calls or SMS. Speeds and coverage depend on the local mobile networks in each destination.

Refunds
A plan is refunded in full on request as long as the eSIM has not been issued. If you asked us at checkout to issue it straight away, the plan is not refundable once it has been issued. If you did not ask for that, you have 14 days to change your mind, and we refund what you paid less a proportionate amount for any data you used. Either way, if the eSIM could not be activated in its coverage area through no fault of yours, we refund in full.
Refund policyUseful questions
What does unlimited data mean?
Your data keeps working for every day of the plan: there is no total allowance to run out. Each day includes an amount at full speed — 500 MB on Basic, 1 GB on Enhanced Speed — and after that data continues at the speed the plan states, up to 512 kbps or up to 1 Mbps, until the next day begins. Every plan shows its own numbers before you pay.
Will it work on my phone?
Your phone needs to support eSIM and must not be locked to one carrier. Most recent iPhone, Google Pixel and Samsung Galaxy models support eSIM, but some models sold in certain countries do not — check your phone’s settings before you buy, because an eSIM installs once.
When do my days start?
For most plans, when the eSIM first connects to a network at your destination, not when you buy it. The plan page says so where a plan works differently.
Will my own number keep working?
Yes. The eSIM is data only: your number stays on your own SIM for calls and texts, at your own carrier’s usual rates. Turn off data roaming on your home SIM so the travel eSIM carries your data.
Do I need an account or an app?
No. You choose a plan on the website, give an email address and pay; the eSIM arrives by email with its QR code. No Flex app or account is required.
How can I pay?
By card, Apple Pay, Google Pay or cryptocurrency — which of these you see depends on your country and device. We charge the US dollar price shown before you pay, whichever you choose; your bank may add its own currency-conversion fee.
Can I get a refund?
A plan is refunded in full on request as long as the eSIM has not been issued. If you asked us at checkout to issue it straight away, the plan is not refundable once it has been issued. If you did not ask for that, you have 14 days to change your mind, and we refund what you paid less a proportionate amount for any data you used. Either way, if the eSIM could not be activated in its coverage area through no fault of yours, we refund in full.
Can I buy one for someone else?
Any plan. You pay, you send them the link, and they install it themselves — no app, no account, no invitation. The link never carries your receipt, your card or your other plans, and it cannot ask for your money back. It is theirs from the moment it is on their phone.
