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.
03
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.
04
GDPR-safe
Data is stored in the EU, with no subprocessors outside the EEA without explicit consent. A DPA is available on request and opt-out is handled automatically.
Frequently asked questions
Can I use multiple Sender IDs at once?
Yes. Rotate per segment, campaign or language with no hard cap.
How do I pay?
Crypto (BTC, ETH, USDT) via NOWPayments or card via Banxa. Balance is active as soon as payment is confirmed.
Is SMS content logged?
Metadata is logged for DLR and support. Message content can be pseudonymized or deleted on request.
Can I send OTP?
Yes. Low latency, high queue priority and separate throughput limits for transactional SMS.
How is opt-out handled?
Automatically through STOP/AVSLUTA — the customer is placed on a per-sender blocklist. You can also whitelist.
Do I need KYC or verification?
No. Sign up, top up and send. No forms, no application, no waiting.
