About this card

COSMOTE is the largest mobile network in Greece, launched in 1998 and operated today as the consumer brand of OTE Group (Hellenic Telecommunications Organization). OTE has been part of Deutsche Telekom since 2008 — the same group behind T-Mobile — and serves several million prepaid (καρτοκινητό) and contract subscribers across Greece, with the country's deepest 4G/5G footprint and the largest physical retail estate (COSMOTE / Γερμανός stores in every city, kiosks in every village).

This card is a prepaid mobile top-up voucher. The 14-character code we deliver loads airtime balance onto a COSMOTE prepaid SIM (COSMOTE Καρτοκινητή, What's Up, and other COSMOTE prepaid product lines). Once redeemed, the credit spends like cash on the SIM: domestic calls, SMS, mobile data, international calls, EU roaming, plus the option to convert it into a fixed-term bundle (πακέτο) for cheaper minute/data rates — all chosen from the My COSMOTE app, no extra charge.

Redemption takes seconds. From the COSMOTE prepaid SIM dial *131*VOUCHER# and press call — balance lands instantly. Or open the My COSMOTE app, tap Top up → Use voucher, paste the code. Or sign in at cosmote.gr/topup. Three roads, same outcome. The voucher itself is valid for at least 6 months from issue, and after redemption the airtime balance is good for 12 months from your most recent top-up under Greek consumer law.

Why crypto for a mobile top-up. The official COSMOTE web portal expects a Greek-issued card or IBAN — usable from inside Greece, awkward from abroad. Crypto removes that friction: travellers keeping a Greek prepaid SIM alive, the Greek diaspora topping up parents back home, dual-SIM users avoiding the foreign-card surcharge, anyone preferring not to leave a card-issuer trail on their phone bill. We collect a single email address to deliver the voucher and nothing else — no name, no Greek tax ID (AFM), no COSMOTE login. The 1.5 % discount you see below is what we save on payment processing versus card networks, passed straight back to you (mobile top-ups are thin-margin globally, so it's smaller than a tech-retail card — still better than any bank's FX spread on a top-up from outside the eurozone).

What you get

A claim code, delivered by email
A private order page (14-day access)
Re-issue or full refund if the code fails
No COSMOTE login or ID required

How to redeem

Same flow on every COSMOTE store — only the URL changes per region.

USSD (fastest): on the COSMOTE prepaid SIM, dial *131*VOUCHER# and press call — replace VOUCHER with the code from the delivery email. Balance lands in seconds, confirmation SMS follows.
My COSMOTE app: open the app, tap Top up → Use voucher, paste the code, confirm.
Web: sign in at cosmote.gr/topup → enter the voucher code → submit. Balance applies to the SIM tied to the My COSMOTE account.

The credit lands on the SIM as standard prepaid airtime — usable for calls, SMS, data, or to renew a COSMOTE prepaid bundle (πακέτο) from the app. Check balance any time with *1330#.

Region terms

Specific to Greece

Greece · EUR

Loads airtime credit on a COSMOTE prepaid SIM in Greece. Redeem via *131*VOUCHER# or the My COSMOTE app. Voucher valid 6 months; airtime balance valid 12 months from last top-up.

Universal terms

Greece only. Voucher redeems only on a COSMOTE prepaid (καρτοκινητό) SIM — not on postpaid contracts, not on COSMOTE Fiber / TV bills, not on any other Greek carrier.
Voucher validity: at least 6 months from issue date. Redeem within that window and the balance transfers in full.
Airtime validity: after redemption, the balance is usable for 12 months from the most recent top-up on the SIM. A SIM that goes 12 months without any top-up may have its balance zeroed and the line eventually deactivated by COSMOTE.
Refunds: if the voucher fails to redeem, contact us via your order page within 14 days — we re-issue a fresh code or refund the full amount in your original coin. No proof of purchase needed.
No transfers. Once redeemed, credit is locked to the receiving SIM. COSMOTE does not allow balance transfers to other COSMOTE lines, to postpaid plans, or to other carriers.
The voucher is a bearer instrument: anyone who has the code can redeem it, so treat the delivery email as you would cash.

Asked & answered

Specifics for COSMOTE cards. For general crypto-payment questions, see the site FAQ.

Which COSMOTE accounts can use this voucher?

A COSMOTE top-up voucher loads airtime credit onto a COSMOTE prepaid (καρτοκινητό) SIM in Greece — for example, COSMOTE Καρτοκινητή or What's Up. It does not work on COSMOTE postpaid (συμβόλαιο) plans, on COSMOTE Fiber/TV bills, or on any other Greek operator (Vodafone, Nova, etc.). If you're unsure which line you have, dial *1330# on the SIM — prepaid SIMs return a balance, postpaid lines return an error.

How do I redeem the voucher?

Three options, fastest first. (A) USSD: on the COSMOTE prepaid SIM dial *131*VOUCHER# and press call — the voucher number replaces VOUCHER, balance lands within seconds. (B) My COSMOTE app: open the app → Top up → Use voucher → enter the code. (C) Web: sign in to cosmote.gr → My COSMOTE → Top up → enter the voucher code. All three apply to the SIM tied to the account.

What can I spend the airtime on?

The credit is real airtime balance: it covers domestic calls and SMS to any Greek network, mobile data (or you can buy a data add-on package out of the balance via the My COSMOTE app), international calls and SMS at COSMOTE's standard prepaid rates, and roaming usage outside the EU (inside the EU, "roam-like-home" applies on most prepaid plans). You can also use it to renew or upgrade a COSMOTE prepaid bundle (πακέτο) without any extra payment.

How long is the voucher valid? How long does the airtime last?

Two separate clocks. The voucher code we deliver is valid for at least 6 months from issue — redeem it on a SIM before that and the balance transfers in. Once redeemed, the airtime balance stays usable for 12 months from your most recent top-up: as long as you (or anyone else) tops up the same SIM at least once a year, the credit never expires. If a SIM goes 12 months without a top-up, COSMOTE may zero the balance and eventually deactivate the line.

I don't have a COSMOTE prepaid SIM. Can I still use this card?

You'd need a COSMOTE prepaid SIM in order to redeem. They're sold over the counter at any COSMOTE/Γερμανός store across Greece, at thousands of kiosks (περίπτερο), and at supermarkets — typically €5 to €10 with starter credit. Greek law (Ν. 4790/2021) requires ID at activation, so plan for a passport or national-ID at the SIM-purchase step. The voucher you bought from us has nothing to do with that ID step — it loads on whichever prepaid SIM you ultimately activate.

Can I transfer the credit to another SIM or carrier?

No. Once the voucher is redeemed against a specific COSMOTE prepaid SIM, the credit is locked to that line. COSMOTE does not allow balance transfers to other COSMOTE SIMs, to postpaid plans, or to any other Greek carrier. Decide which SIM you want to top up before dialling *131*.

What if the voucher fails to redeem?

Open your order page from the delivery email within 14 days. We re-issue a fresh code or refund the full amount in the original coin you paid in — no forms, no proof of purchase, no questions. Most failures are typos when entering the long code on the keypad; if USSD returns an error, switch to the My COSMOTE app and paste the code instead of typing it.

Why pay in crypto for a mobile top-up?

Three reasons. No Greek bank needed: the COSMOTE web top-up portal expects a Greek-issued card or IBAN — useful for diaspora, dual-SIM travellers, and anyone keeping a Greek prepaid line alive while based abroad. Privacy: no card-issuer trail tying your phone line to your bank statement. Convenience: works at 3 AM, no exchange-rate gouging, no card-not-present fees. Mobile top-ups are thin-margin globally, so the discount is modest (1.5 %) — but it still beats every Greek bank's FX spread on a card top-up from outside the eurozone.
