One SIM for Telkom, MTN, and Vodacom

Revolutionising Connectivity: Saicom’s APN Service with Telkom Mobile Roaming

In today’s fast-paced digital world, staying connected is more important than ever. Whether you’re a business professional on the move, a remote worker, an IoT device manager, or simply someone who values uninterrupted connectivity, having reliable access to mobile networks is crucial. At Saicom, we understand this need, and that’s why we’re excited to introduce our innovative APN service that leverages the power of Telkom Mobile SIM cards that  roam on MTN and Vodacom base stations.

Unparalleled Network Access with One SIM

One of the standout features of our APN service is the ability to use a single Telkom Mobile SIM card (physical or virtual eSIM) to access all three major networks in South Africa—Telkom Mobile, MTN, and Vodacom. This unique solution ensures that you are always connected, no matter where you are in the country. Whether you’re in a bustling city or a remote location, our service provides you with seamless connectivity, leveraging the extensive coverage of all three networks.

How It Works

Our partnership with Telkom Mobile allows us to offer SIM cards that can roam across MTN and Vodacom base stations. This roaming capability means that if Telkom Mobile’s network signal is weak or unavailable in a particular area, your device will automatically switch to the strongest available signal from MTN or Vodacom. This automatic switching ensures that you maintain a stable and reliable connection without any manual intervention.

Telkom’s recent restructuring of its roaming agreements has significantly enhanced the experience for users. Previously, Telkom relied heavily on its network, supplemented by limited roaming on MTN. Now, with extended agreements, Telkom Mobile SIMs can seamlessly roam on both MTN and Vodacom networks, providing a more robust and comprehensive coverage solution. This means that our customers can enjoy improved connectivity across urban and rural areas alike.

The Benefits of Saicom’s APN Service

  1. Enhanced Connectivity: With access to three major networks, you are guaranteed superior coverage and connectivity, reducing the chances of experiencing network blackouts.
  2. Cost-Effective: By using a single SIM card that roams across multiple networks, you eliminate the need for multiple SIM cards and plans, saving you both time and money.
  3. Simplified Management: Managing one SIM card is far easier than juggling multiple SIMs for different networks. This simplicity extends to billing, support, and overall user experience.
  4. Business Continuity: For businesses, reliable connectivity is synonymous with productivity. Our APN service ensures that your team remains connected, no matter where their work takes them.
  5. Optimised for IoT: One of the most exciting applications of our APN service is in the realm of the Internet of Things (IoT). IoT devices often need to operate in diverse locations and environments, requiring consistent and reliable network connectivity. With our APN service, you no longer have to worry about which SIM card to use in your IoT devices. The ability to roam on MTN and Vodacom networks ensures that your IoT devices remain connected, facilitating seamless data transfer and remote management.
  6. Resilience During Load Shedding: Load shedding is a reality in South Africa, and power outages can affect the availability of network base stations. With our APN service, if one network’s base station goes down due to load shedding, your device will automatically switch to another network’s base station that is still operational. This redundancy ensures that you stay connected even during power outages, providing peace of mind and uninterrupted service.

Centralised Management with Mosaic

Managing your connectivity has never been easier, thanks to our centralised portal, Mosaic. Mosaic is Saicom’s robust management platform that allows you to oversee and control all aspects of your APN service from a single interface. With Mosaic, you can:

  • Application Reporting: Application layer usage reporting (e.g., Facebook, YouTube, Salesforce, etc.)
  • Analytics: View graphing and analytics to understand usage patterns.
  • Centralised Bundle: All SIM cards, across all networks, consume off a central enterprise bundle.
  • Capping: Configure data capping on individuals. Each connection to the network will require a SIM card. Each individual can be assigned multiple SIM cards (up to 5) with a single individual data cap.
  • Pairing of ICCID to IMEI (Phone to SIM Card): This feature renders a SIM card useless unless used with the intended device.
  • Soft Lock: Manually soft lock and unlock SIMs in real time.
  • Top-ups: Administrators can top up individuals’ SIMs with additional data (out of the centralised enterprise bundle).
  • Organise SIMs: Manage multiple APNs, sites, departments, individuals, and SIM cards.
  • Notifications: Custom notification percentages with notifications sent to WhatsApp, Telegram, SMS, and email.
  • Custom Fields: Add custom fields to manage specific details relevant to your organisation.
  • SIM Cancellation: Easily cancel SIM cards when they are no longer needed.
  • IP Pools: Manage which IP pools SIM cards belong to straight from the portal.

Mosaic simplifies the complexity of network management, providing you with the tools and information you need to ensure seamless connectivity across your devices and locations.
