Hon. @samgeorgegh , I'd like to ask a question on behalf of Ghana's startup ecosystem.

Why are .gh domains significantly more expensive than .ng domains in Nigeria?

For many startups, developers, students, and small businesses, the cost of securing a local domain is a barrier to building under Ghana's digital identity. If our goal is to accelerate digital transformation, shouldn't .gh domains be more affordable and accessible?

Would your ministry consider reviewing the pricing model to encourage wider adoption of .gh domains?

AI Agents are coming hard in 2026.

But they’ll still need reliable communication layers (voice, WhatsApp, SMS) to talk to humans.

The real winners won’t just build smart agents — they’ll build agents that can actually reach users reliably across Africa.

Who’s already experimenting with AI + comms?

[Collins Vidzro @collinsvidzro]

POV: CEO of a comms platform at 2 AM debugging why OTP delivery dropped in one country 😅

Today’s fix: Added a new local partner that increased delivery by 19% overnight.

This is what building reliable infrastructure in Africa looks like.

What’s the hardest technical challenge you’ve faced this month?

[Collins Vidzro @collinsvidzro]

2026 African Tech Reality:

Your users are on 3+ networks at once.

If your OTP only tries MTN, you’re losing 30–40% of users.

Multi-carrier intelligent routing isn’t a luxury — it’s table stakes now.

We built exactly that at @Sendexahq

What network issues are you seeing?

[Collins Vidzro @collinsvidzro]

Hot take:

WhatsApp Business API is eating SMS in Africa in 2026.

But 70% of businesses are still using it wrong (generic templates that get low response).

The winners are using interactive + personalized flows.

When building auth/OTP flows, what matters MOST to you?

A) Speed of delivery

D) Compliance & data privacy

Thread: How we built Africa’s most reliable OTP system in 2026 🧵 (1/6)

Most OTPs fail because of:
1. Poor routing
2. No fallback
3. Ignoring local regulations

Here’s what actually works in Africa...

(Continue with 5–6 points + your solution)

[Collins Vidzro @collinsvidzro]

🚀 Pro Tip for African devs:

Never use free international SMS APIs in 2026.

Why?
- Delivery rates drop below 60% during peak hours
- OTPs get blocked by local telcos
- You lose customers at checkout

At Sendexa, we route locally first → 98%+ delivery in Ghana, Nigeria, Kenya.
