🔥 Why You Should Stop Using *312#
MTN’s *312# is the most commonly used code for buying data. But what most users don’t know is that it offers the most expensive bundles. In fact, every time you use it, you’re missing out on hidden deals and promo bundles.
Instead, try the codes below for cheaper, smarter, and more flexible data offers.
✅ 1. Smart Data Hack – The ₦200 for 1.5GB Trick
Code: *312*888# (MTN Only)
This is one of the best-kept secrets for MTN users.
- For ₦200, you get 1GB + 500MB = 1.5GB (valid for 30 days).
- Buy it 5 times and you get 7.5GB for just ₦1,000.
- Buy it 20 times and that’s 30GB for ₦4,000 — beating every regular plan out there!
🔗 Best for: Students, streamers, light app users, and anyone who uses data often.
✅ 2. Airtel Triple Benefit Plan (Data + Calls + SMS)
Code: *312*10*1#
This plan gives you a complete communication bundle. You get:
