🔑 Prerequisites
A successful subscription hinges on three elements staying aligned: a compliant service account, a stable US IP, and a funded MPCard.
MPChat account ready
Install the official MPChat app, complete identity verification, and activate the wallet
Issue an Asia Elite Card (VISA); record the 16-digit card number, expiry and CVC
Network setup
Use a stable US residential IP; avoid public Wi-Fi, datacenter, or shared proxy IPs
Keep IP region consistent with the card and billing address to pass risk checks
Funding ready
Character.AI costs around $9.99/month; stock ~$15 in USDT to cover the $1 pre-auth and FX
Keep card balance ≥ $12 so the first charge is not blocked
