Colonel Potter is spot on about GEO matching — that's the #1 rookie mistake. Card country, billing address, proxy, and ad account region all need to align or you're asking for a flag.
A few more things from my experience running Meta ads for African GEOs:
1. Don't put all spend on one card. Spread across 2-3 cards per ad account. If one gets declined, the account doesn't go into payment failure mode which can trigger a review of everything on it.
2. Warm up new cards slowly. Don't load a fresh VCC and immediately set a $500/day budget. Start with $20-30/day for the first 3-4 days, then ramp. Meta's payment system flags sudden high charges on new payment methods.
3. Keep a backup payment method always. If your primary card gets declined and you have no backup, Meta pauses all campaigns and sometimes triggers an account review. Having a second card ready means the system auto-falls back without disrupting your campaigns.
4. Avoid cards with low authorization rates. Some cheap VCC providers have 60-70% auth rates — meaning 1 in 3 charges fails. Those repeated declines absolutely destroy your payment trust score with Meta/Google.
The real long-term play is getting a business bank account with a proper debit card from a neobank. More expensive upfront but the authorization rates are 99%+ and you never deal with BIN burning.
