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
Your own Sender ID
Set any sender name you want, up to 11 alphanumeric characters. No pre-approval, no waiting, no follow-up questions. Change Sender ID between campaigns or use different IDs per segment for A/B testing.

How is opt-out handled?
