OTP codes and two-factor on Zalo

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.

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.

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.

One price per SMS, no monthly fee, no lock-in contract. Balance never expires and you see the exact campaign cost before you press send.
