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.
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

No — one flat price of 0.89 SEK/SMS up to 100,000 per month. Sending more? Contact us for enterprise pricing.
Can I use multiple Sender IDs at once?
Yes. Rotate per segment, campaign or language with no hard cap.
How is opt-out handled?
Automatically through STOP/AVSLUTA — the customer is placed on a per-sender blocklist. You can also whitelist.
