eSIM for Spain
Buy a prepaid travel eSIM for Spain and pay in cryptocurrency. You get local 4G/5G data on partner networks without a contract or a local address. No documents, no account and no email: you pay in crypto and the QR code appears on the page.
Part of our Europe plan.
Buying an eSIM for Spain
- Pick a plan that covers Spain — a single-country plan is cheapest per gigabyte, a regional plan pays off the moment you cross a border.
- Pay with USDT, BTC, ETH, SOL, TON or XMR. No email address, no account, no card.
- Scan the QR that appears on the page. Do this at home over Wi-Fi rather than on airport Wi-Fi after landing.
- On arrival, set the eSIM as your data line and turn data roaming ON for it. This is the single most common reason a correctly installed profile shows no data in Spain.
Coverage and network quality in Spain
The profile attaches to local partner networks, so you are on the same towers local subscribers use — not a degraded roaming tier.
5G is widespread in Madrid, Barcelona, Valencia and Seville; rural Andalusia and the interior drop to solid 4G.
Speeds track the local network rather than the brand on your checkout page: no travel eSIM provider owns towers, all of them buy wholesale capacity from these same carriers.
eSIM vs roaming vs a local SIM in Spain
- EU residents roam in Spain at domestic rates; everyone else is on standard roaming, typically $10–15 a day.
- A local prepaid SIM is cheap but costs you an hour on arrival, usually an ID, and a phone number you will not keep. In Spain, that trade only makes sense on a long stay.
- A travel eSIM sits in between: local-network speeds, no shop visit, no paperwork, and your own number stays live on your physical SIM for calls and SMS.
Compatible devices
- iPhone XS and newer (any model with eSIM support).
- Google Pixel 3 and newer.
- Samsung Galaxy S20 and newer (varies by region — some Asian variants ship without eSIM).
- Most 2020+ flagship Android devices. Dial *#06# — if an EID is listed next to the IMEI, your phone supports eSIM.
Practical notes for Spain
If your trip includes Portugal, France or Italy, a regional Europe plan is almost always cheaper than buying one country at a time.

Frequently asked questions
Do I need an ID or KYC to buy an eSIM for Spain?
No. Cypher eSIM never asks for a name, email, phone number or government ID. You pay in cryptocurrency and the QR code appears on the page — that is the whole flow, for Spain and everywhere else we cover.
How good is coverage in Spain?
5G is widespread in Madrid, Barcelona, Valencia and Seville; rural Andalusia and the interior drop to solid 4G. Your phone picks whichever network has the best signal where you are, the same way a local handset does.
Can I install the eSIM before travelling to Spain?
Yes, and you should. Install it at home over Wi-Fi; the plan only starts counting from the moment your device first connects to a network at the destination, so buying days ahead costs nothing.
Will I keep my own phone number in Spain?
Yes. The eSIM is data-only and runs alongside your physical SIM, which keeps your number live for calls and SMS. Just make sure the eSIM is set as the data line so nothing routes over your home carrier at roaming rates.
Can I buy an eSIM with cryptocurrency?
Yes. Cypher eSIM accepts USDT (TRC-20, BEP-20, Arbitrum, Solana), Bitcoin (BTC), Ethereum, Solana, USDC, DAI, Monero (XMR), TON. After payment, you receive your eSIM QR code within 60 seconds — no email, no login, no KYC required.
Is a no-KYC eSIM legal?
Yes, in most jurisdictions. KYC requirements vary by country, but using an anonymous eSIM for personal travel is legal in the US, EU, UK, and most of Asia.
How fast do I get the eSIM after payment?
Within 60 seconds. As soon as the crypto transaction is confirmed on-chain, the QR code is generated and shown on screen.
