Delivery rate that holds

Direct connections to Telia, Telenor, Tre and Tele2 provide stable delivery to Swedish numbers. Real-time DLR shows exactly which SMS were delivered, pending or bounced — nothing sits in dark queues.

Crypto and card payments

Top up with BTC, ETH or USDT via NOWPayments, or by card through Banxa. Balance is available as soon as payment is confirmed — usually within 60 seconds.

No KYC or application

Other platforms force you through weeks of verification before the first SMS. We do not. Sign up, top up, send. That simple.

Support that answers

We operate from Sweden. Ping us and a technician answers — not a chatbot, not a tier-1 agent escalating. Directly to someone who knows the system.

Frequently asked questions

Is there an API?

Yes. REST API with examples for Node.js, Python, PHP, Go and Ruby. See /api/rest for documentation.

How is opt-out handled?

Automatically through STOP/AVSLUTA — the customer is placed on a per-sender blocklist. You can also whitelist.

Can I schedule campaigns?

Yes. From the dashboard or API, including timezone-aware scheduling and batch sends.

Can I send OTP?

Yes. Low latency, high queue priority and separate throughput limits for transactional SMS.

Is SMS content logged?

Metadata is logged for DLR and support. Message content can be pseudonymized or deleted on request.

Are there volume discounts?

No — one flat price of 0.89 SEK/SMS up to 100,000 per month. Sending more? Contact us for enterprise pricing.
