Kastelo, a South African fintech and telecommunications company, is on a mission to shake up the local mobile market by delivering smarter, fairer digital services. With a strong focus on transparency, customer empowerment, and innovative digital solutions, Kastelo operates as a licensed mobile virtual network operator (MVNO)—leveraging existing mobile infrastructure to provide users with a better, more affordable experience.

Their latest product, GIGS, is a mobile service built for modern South Africans who are tired of data bundles expiring, confusing billing, and hidden terms. GIGS makes mobile data simple again: no expiry dates, no separate bundles, and no nonsense.

Here’s why GIGS is making waves:

1. Data That Never Expires

One of the standout features of GIGS is that your data doesn’t come with a ticking clock. Unlike traditional mobile data bundles that vanish at the end of the week or month, whether you use them or not, GIGS ensures that what you pay for stays in your account until you actually use it. This is a game-changer for users with irregular usage patterns—whether you’re a student, freelancer, or someone who travels often and doesn’t need data every day. It’s simple: buy once, use when you need it.

2. Transparent Pricing – Only R30/GB

No sliding scales. No peak-hour pricing. No bundle traps. GIGS charges a flat R30 per gigabyte, giving you a straightforward way to manage your data spending. You can top up with as little or as much as you need, without worrying about being locked into expensive monthly contracts or dealing with arbitrary bundle rules. This transparent, pay-as-you-go model helps customers make informed decisions and avoid bill shock at the end of the month.

3. One Balance for Everything: Data, Voice, SMS

Say goodbye to juggling multiple balances. With GIGS, there’s one unified balance for everything: data, voice calls, and SMS. That means if you top up with 5 GB, you can choose to use part of it for calls, part for texting, and the rest for browsing—whatever suits your needs. It gives you the flexibility to communicate how you want, without waste or restrictions. You’re in full control.

4. Instant eSIM Activation – No Need to Visit a Store

GIGS is built with digital convenience in mind. If your device supports eSIM, you can activate your mobile service instantly through the Kastelo app—no physical SIM card, no store visits, no waiting. Just download the app, register, and complete FICA verification, and you’re online within minutes. For those who still prefer a physical SIM, Kastelo has partnered with over 80 Clicks stores nationwide, offering convenient in-person pickup.

5. Available in Over 80 Clicks Stores Nationwide

Accessibility is key. Kastelo has partnered with Clicks—one of South Africa’s largest retail pharmacy chains—to make GIGS available at 80+ locations across the country, including major cities like Johannesburg, Cape Town, Durban, Pretoria, Port Elizabeth, and Bloemfontein. Whether you’re in a big city or a smaller town, you can walk into a Clicks store, register, and walk out with a working SIM—ready to connect. It’s a mobile service that meets you where you are.

6. No Gimmicks, No Hidden Terms, No Bundles

Tired of promotions that sound good but hide the real costs in the fine print? So is Kastelo. GIGS is intentionally built to be gimmick-free—no surprise fees, no confusing bundle tiers, and no tricky promotional conditions. What you see is what you get. Their model is designed around honesty and simplicity, challenging the status quo of the South African telecom market and offering customers a refreshing level of trust and clarity.

Why It Matters

• Cost-efficient and fair: The flat rate means transparency—users only pay for what they use.
• Perfect for flexible mobile users: With no expiry dates, GIGS adapts to changing habits—great for part-timers, travelers, or anyone with variable data needs.
• Digital-first & user-friendly: eSIM activation and app-based top-ups suit today’s digitally native users.
