Guys, urgent update for June 2026.

If you dial *556# on MTN or *124# on Airtel today, you go see "Connection problem or invalid MMI code".

NCC changed all codes since 2023. MTN, Airtel, Glo, 9Mobile now use the SAME codes.

New codes that work right now:

*310# - Check airtime balance
*312# - Buy data
*311*PIN# - Recharge airtime
*323# - Check data balance
*303# - Borrow airtime/data
*996# - Link NIN to avoid SIM block

Full list + why old codes died + how to fix errors:
