Wrong question. Airtel’s catalogue is built so different habits trigger different bargains . This post dissects every current tariff, then maps the optimal pick to eight everyday profiles—from parents with school kids to crypto traders awake at 2 a.m. Keep reading; you’ll see how a clever combo ends up cheaper than the beloved 15-kobo SmartValue plan we lost.

Quick Primer: Airtel Tariff Families, Post-Hike

Plans like Freedom, SmartValue and 6× Bundles are gone; *121# now lists only the rows above.

How We Measured “Cheapest”

1. Effective kobo per second after all bonuses/bundle maths.
2. Predictability—no daily fees that punish light callers.
3. Ease of subscription & rollover.
4. Ancillary data needs—because pure voice is rare in 2025.

Best Tariff For Every User Type

1. The “Pay-As-You-Need” Light Caller

Pick: SmartTalk Ultra
25 k/sec, no fees; welcome 400 % bonus softens the first 90 days.
Why: You talk < 60 min/month, hate bundle expiry, want one simple USSD (314#).

2. The Chatty Uncle (60–250 min/Month)

Pick: TalkMore Bundles —start with 500 (₦500 → 50 min).
Effective 16.7 k/sec beats every other Airtel plan when you finish the pack.
Buy via 2341#*, stack packs to rollover minutes.

3. The Voice + Data Multitasker

Pick: Flexi 1 000 (₦1 000 → 20 min + 1.2 GB + 5 SMS).
You pay 50 k/min (~13 k/sec)and ₦0.83/MB—half today’s PAYG ₦4.6/MB.

4. The Night-Owl Student

Pick: SmartTRYBE
After the first 90 s each day your calls cost just 13 k/sec; ₦25 buys 250 MB midnight data—₦0.10/MB, far below 2025’s ₦431/GB benchmark

5. Primary-School Kids

Pick: SmartTRYBE Junior + ₦200 FAF Bundle
Free daily calls to Mum & Dad, 11 k/sec to registered friends, 100 % data bonus, zero-rated learning app.

6. One-Man SME Making Daily Quick Calls

Pick: SmartTalk Ultra + Tiny TalkMore 100 Packs on busy weeks.
No daily fee baseline; pop a 10-minute pack at ₦100 whenever you foresee heavy outreach.

7. Social-Media Vendor (Data-First, Occasional Voice)

Pick: Flexi 2 000 (40 min + 2.5 GB @ ₦2 000). Use WhatsApp for long calls—0.35 MB/min = ₦0.29 inside the bundle.

8. Heavy Everyday Chatter (≥ 5 min/day)

Pick: Remain on Airtel but bolt on TalkMore 1 500 (150 min for ₦1 500) every 30 days. Effective 16 k/sec, no surprises.

Conclusion: One Network, Many “Cheapest” Plans—Pick Yours Wisely

Post-hike Airtel pricing forces you to choose situational bargains rather than one master tariff. SmartTalk Ultra is unbeatable for ultra-light callers; TalkMore shreds cost for predictable chatters; Flexi conquers the voice-plus-data middle; SmartTRYBE rules students and insomniacs; Junior protects kids and wallets alike.

Layer any of them with discounted airtime from SmartSMSSolutions and occasional WhatsApp calls, and you’ll still pay below the new ₦16.5/min national average despite the NCC-approved 50 % hike. If you haven’t done so yet, dial * 121# right now, match your habit to the profile above, and start pocketing every kobo the new tariff era still leaves on the table.
