Mobile data for your phone, in Czechia and abroad. No account, no commitment, and an invoice for every order. NO ACCOUNT, NO SURPRISES • Pay with Apple Pay or a card, no account needed. • Your eSIM arrives by e-mail after payment. Install it with the QR code or manually with a step-by-step guide. • Prices are final, in Czech koruna. AT HOME: EXTRA DATA • Ran out of data with your carrier? Add data on an eSIM that runs next to your number. Calls and SMS stay with your carrier. • A plan with no commitment: data renews every 30 days and you cancel anytime in the app. • Data for a tablet or a second phone, too. ABROAD: NO ROAMING • Egypt, Turkey, Thailand, USA, Europe and more destinations. • Every offer shows its price in Czech koruna; packs with a fixed amount of data also show the price per GB. • Unlimited packs show their fair-use rules. We don’t sell offers that slow below 1 Mbps after the limit. • Out of data? An eSIM that supports top-ups can be topped up with one tap, no new install. SEE EVERYTHING • Data-usage overview from the carrier’s latest reading; updates can lag by several hours • Push alerts based on the carrier’s latest reading when reported data runs low • eSIM card in Apple Wallet, a home-screen widget and a Live Activity with remaining data right on your Lock Screen FOR THE WHOLE FAMILY • Name who the eSIM is for when you buy, then send it to them with a link. All your eSIMs sit together in the app. A CZECH COMPANY, INVOICES WITH COMPANY ID • Support in Czech, English, German and Ukrainian. The app also speaks Slovak, Polish and Vietnamese. • An invoice for every order, also for a company with an IČO.

Verdict
The clearest difference is ads: Vlex eSIM at none against TvojeData's shown. Vlex eSIM also leads on device support (3 vs 1). TvojeData's advantage is update cadence (every 2 weeks vs monthly). On price, in-app purchases and iOS requirement there is nothing between them.
