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.
Scales with you
500 MPS by default, upgradeable on demand. From your first OTP to millions of marketing SMS per day — same infrastructure, same API, no migration.
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.
Frequently asked questions
How is opt-out handled?
Automatically through STOP/AVSLUTA — the customer is placed on a per-sender blocklist. You can also whitelist.
How do I pay?
Crypto (BTC, ETH, USDT) via NOWPayments or card via Banxa. Balance is active as soon as payment is confirmed.
Can I choose any Sender ID?
Yes. Set any sender name you want, up to 11 characters. We do not pre-review Sender IDs for you.
Can I send OTP?
Yes. Low latency, high queue priority and separate throughput limits for transactional SMS.
Can I schedule campaigns?
Yes. From the dashboard or API, including timezone-aware scheduling and batch sends.
Can I use multiple Sender IDs at once?
Yes. Rotate per segment, campaign or language with no hard cap.
