Everything you need to know about unsteered Multi-network SIM cards

Got a question about our unsteered Multi-network SIM cards? Whether you’re wondering how they’re different from their steered counterparts, how they work with international roaming, or what makes them the unbeatable choice for making sure your devices connect anywhere, check out our FAQs below.

What is a Multi-network SIM, anyway?

Unlike their single-network counterparts, an Multi-network SIM card is one that’s able to access many or all of the networks in a given location.

Why should I choose a Multi-network SIM over a consumer SIM?

Not all networks have strong coverage everywhere. With multiple networks at your disposal (so for example, in the UK: O2, EE, Vodafone, and Three) you’ll never have to worry about coverage, no matter where you are anywhere in the world.

You’ll also enjoy better bandwidth, better resilience, effortless deployments, and business grade APNs, to name a few!

What’s the difference between steered and unsteered Multi-network SIMs?

Steered SIMs have access to multiple networks, but cling to the one they prefer; even when the signal’s awful.

Our unsteered Multi-network SIMs always prioritise connectivity. They detect all available networks anywhere they go, so your device is free to connect to the strongest option—which is why your customers will love Multi-network!

How do the Multi-network SIMs switch from one network to another?

Multi-network SIM cards automatically compile a list of available networks, then connect to the one with the strongest signal. You don’t need to do anything like switch the device off and on or reconfigure its settings.

Will the customer notice if the Multi-network SIM switches network?

When switching, the device has to re-register on another network, so there may be a brief 30-60 second delay in re-connecting.

How many networks are available on Multi-network SIMs, and how many are 4G?

That depends on the country’s networks. For example, in the UK there’s coverage available on O2, Vodafone, EE, and Three, all on 4G, anywhere you take the Multi-network SIMs.

Can I choose a specific network?

Yes, you can set the SIM to prefer a specific network (but this should be for troubleshooting only, as locking it to a single network removes the Multi-network capability!).

If there’s a network outage, how does my SIM find the next strongest network?

If your Multi-network SIM loses signal, the device modem will immediately search for a new network to connect to. Some devices use extra logic, like pinging a certain IP address, to determine if connectivity is lost and to reconnect.

How does international roaming work on a Multi-network SIM card?

M2M SIM roaming is different to consumer roaming. The countries, networks, and features are agreed in advance with your account manager.

Can I keep track of my usage with Multi-network SIM cards?

You’ll have a comprehensive view and detailed reports on each SIM’s activity through our IoT portal. And you can set up custom usage alerts. So you won’t have any ‘bill shock’ moments to worry about.

Multi-network SIMs are only good for small amounts of data, right?

Nope! Our Multi-network SIMs have been used for everything ranging from small kilobyte requirements to massive terabyte solutions. We’ve got you covered no matter how much data you need.

What if I go over my data allowance?

No problem. If you use all your data, you can opt for one of our top-up options. Alternatively our self-adjusting tariffs with prevent you from going over your data allowance; or if you have multiple SIMs, we can pool your data. We’ll help you choose the best option for you.

Can I cap my data usage?

Yes. You can do so through our notification system in our IoT Portal.

Can I choose my IP?

Yep! Both public and private static IPs are available, as well as dynamic IPs for general Internet access.

Why would I need a static IP address on a SIM? And what’s the difference between public and private IP?

While it’s not always necessary, having an IP address on your SIM is great in certain situations, like running a server or hosting applications.

Can I use voice & SMS with Multi-network SIMs?

You can—but make sure your solution takes the SIM’s country and phone number into account.

Can I bundle voice and minutes?

Sure! Ask your account manager and they’ll make it happen.

Will the SIM have a UK number? Does it matter?

No, Multi-network SIMs don’t have UK numbers by default. You’ll only need to consider securing a UK number if SMS or voice needs to be used.

Is it a pop-out SIM?

Yep! Pop it out as you see fit.

Can I lock the SIM to an IMEI?

Yes. This can be done for all our Multi-network SIMs, as well as most of our managed SIM cards.

Can the SIMs whitelist sites or filter web content?

Yes! You can whitelist however you see fit, or we can equip all your Multi-network SIMs with a customisable, AI-driven content filter that keeps your connectivity and your users safe.

How easy is it to configure my SIM to a device?

Very! You just have to enter the APN name. No username or password is required. The APN name will be advised at the time of order; or you can ask our support team, or find it in our knowledge base.

Why doesn’t every network offer this service as standard?

While most networks are able to provide steered SIMs, not many have the capability to offer unsteered Multi-network as an option—especially with L2TP and IP addressing options.
