📖 Overview
Grammarly Premium is an English writing assistant offering advanced grammar correction, rewrites, tone suggestions and plagiarism detection from about $12/month (varies by billing cycle). This guide walks through paying with an MPChat Asia Elite Card.
🔑 Prerequisites
A successful subscription hinges on three elements staying aligned: a compliant service account, a stable network environment accepted by the target storefront, 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 network environment accepted by the target service; avoid public Wi-Fi, datacenter, or shared proxy IPs.
Keep account region, billing profile, and network exit aligned as much as possible to pass risk checks.
Funding ready
Grammarly Premium costs around $12/month; stock ~$18 in USDT to cover the $1 pre-auth and FX
Keep card balance ≥ $14 so the first charge is not blocked
📝 Step-by-Step Subscription Guide
Phase 1 - Prepare the MPCard
Top up USDT
Path: MPChat App → Wallet → Deposit - Copy your dedicated USDT deposit address - Send USDT from an external wallet or exchange - Wait for network confirmation (usually 5-15 minutes)
Issue an Asia Elite Card (VISA)
Path: MPChat App → MPCard → New Card - Card type: Asia Elite Card (VISA) - Generated instantly; save the card details
Move funds onto the card
Path: MPChat App → Wallet → Transfer - From: MP Wallet (USDT) - To: MPCard (USD) - Amount: at least $14 including the $1 verification buffer

Phase 3 - Payment Details (critical step)
Payment method: choose Credit Card, then click Add Payment Method

Verification & activation
