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.
Crypto and card payments
Top up with BTC, ETH or USDT via NOWPayments, or by card through Banxa. Balance is available as soon as payment is confirmed — usually within 60 seconds.
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.
