What are the advantages of using a multi-network roaming SIM?

September 21st, 2018 by Mandy Fazelynia



  • Never lose signal for travelling assets
  • Always be online
  • Critical failsafe for business
  • One SIM for global coverage

Although we are seeing lots of new technology being introduced into the IoT space for connectivity, 3G and 4G connectivity is still the go to service. Cellular connectivity can be used in almost any application for safe, secure transmition of IoT data. But single network solutions do have their drawbacks. Key areas which end users have concern over are when constant critical connectivity is required, what if your single network goes down, where is the resilience? What if your asset is constantly moving, there will always be occasions of cellular coverage on a single network dropping in and out of, or it could be that the SIMs are being installed at the point of manufacture, and your devices could be landing in different countries around the globe. For these reasons, and many more, smart connectors are now using multi network roaming SIMs for their IoT solutions and GPS tracking are just a handful that benefit from this kind of solution.

What is a multi-network roaming SIM?

There are two kinds of multi-network data SIM, steered and non-steered. Both kinds can connect you to multiple network providers, but there is a key difference.

  • A Steered SIM has a primary network that  it will default to when it is available. Even when a better connection is available on a different network  it will always prioritise to the default network. The only time a steered SIM will connect to a different network is when the primary one isn’t available.
  • A non-steered roaming SIM is often the preferred choice when it comes to IoT. eWithout having a primary network a non-steered solution is free to connect to the strongest connection available. As they aren’t steered to a specific network, users will find that their IoT solution performs better.

Here at Zest4 we have access to both the steered and non-steered for our partners, but our recommendation is to always use our non-steered SIM solution for maximum performance.

SIM management

As multi-network roaming SIMs form part of our IoT solution, youl get all the benefits of secure managed data and access to our SIM management platform.  With the ability to view data usage in real time, add caps and bars, view diagnostics, and manage your entire SIM estate. 

Zest4 puts you in total control of your connectivity and offers you the solutions you need to make sure all your IoT connectivity needs are met.

Pre-Ethernet, Cut-the-Wire, Long & Short-Term Connectivity Solutions – Made Even Easier For Re-Sellers

July 19th, 2018 by Anton Le Saux

4G connectivity solutions have seen a huge uptake from our Partners and end users. Our Partners have made sure that their end-users have been supplied with instant connectivity in retail outlets, greenfield sites, new office locations, festivals and one has even stepped in at the last minute to help out the a well-known music venue in Liverpool manage a worldwide video blog for a 60’s and 70’s music legend.

Using this revolutionary IoT technology, our 4G connectivity solutions provide businesses with continuous connectivity, wherever they are, and whenever they need it. Creating the perfect solution for businesses that operate from multiple locations, or for occasions where fixed line connectivity just simply isn’t an option.

We anticipated that the main area of interest expressed by our partners would be for pop-up office solutions, and particularly for businesses moving premises.

As many of us know from bitter experience, huge delays usually occur when waiting for BT Openreach to install fixed ethernet lines, leaving organisations without permanent connectivity for long periods of time, which can have a huge detrimental impact on trading. But, thanks to IoT technology, there is a new solution – a pre-ethernet  / Internet in a Box from Zest4. With specially developed Enterprise Grade Routers, with the ability to incorporate multiple SIMs, organisations can enjoy constant connectivity using mobile networks. Not only is this an ideal solution while you’re waiting for a fixed line to be installed, but it can also be kept as a back-up in case of fixed line faults in the future, making an organisation fail-proof.

At Zest4 we also wanted to take away any barriers to sale, so we are launching the Zest4 Connect Internet in a Box solution, giving our Partners anenterprise grade router, SIM and data package that requires no upfront cost for hardware or the connection.

For a simple competitive monlthy charge we will supply you with the following:

  • A pre-configured enterprise grade router.
  • SIM activation including SIM-install and configuration.
  • Monthly data package included on each SIM.
  • Any size data bundle ensuring full flexibility.
  • Flexible terms from three to 36 months.
  • APN and security settings pre-configured.
  • Device testing prior to shipping.
  • Logistics handling and tracking (devices sent either direct to our Zest4 partner or direct to the end-user).
  • Customer account configured and set up on Zest4 Connect SIM Management Platform including customer log-in details and training, if required.

This is not just available on a UK network. We have recently deployed a significant volume of these to one of the world’s biggest DIY warehousing chain, which are being used across a number of European sites.

This type of temporary mobile connectivity scenario has sparked a lot of interest amongst our Partners but it has also been noted as a potential additional revenue stream. We can offer the possibility of a Router Rental Service, by buying our Enterprise Grade Routers for themselves and then offering them to customers as part of a rental scheme. Not only would this work for businesses moving premises, but also for festival organisers and any other events companies who need mobile connectivity on a few occasions during the year.

If you have a concern about the quality of mobile networks, and what would happen if a network went down, then there is always a possibility for this, but it’s something that Zest4 has planned for, by including several SIM slots in our routers. All our Enterprise Grade Routers come with 2 SIM slots as standard, (meaning customers can connect to two different networks if required), but we can also configure a router to include 4 SIM slots to offer additional back-up if needed.

IoT technology offers customers connectivity capabilities that was deemed virtually impossible, but which could make a huge difference to their businesses. I am incredibly excited for the future of our Ethernet Cut-the-Wire 4G Connectivity Solutions, and to work with our Partners to help their customers and their businesses succeed.
