Benefits of emnify’s
multi-carrier SIM cards
Complete global coverage
The last thing you want is to invest in SIM cards that don’t have the coverage you need. Our SIMs provide 2G, 3G, 4G, 5G, LTE-M, NB-IoT, and even satellite IoT coverage. As our Super Network of 540 carriers grows, we automatically update your SIMs with additional coverage.
No network steering
Unlike traditional cellular providers and many MNOs and MVNOs, emnify doesn’t have a home network—we optimize your connectivity based on your priorities, not ours. Other operators may steer your SIMs to connect to their home network, even if another carrier has better or more affordable service.
Remote SIM provisioning
Some countries (like Brazil) restrict permanent roaming, forcing you to use a SIM profile from a local carrier. Whether you’re trying to stay in compliance or you just need the best coverage, emnify’s multi-carrier SIMs automatically change profiles for free with a Multi-IMSI applet and eUICC.
Use our multi-carrier SIM cards, and you’ll never be stuck in a long-term contract. We use simple, transparent pricing models based on your active SIMs and data needs. You can easily scale your plan up or down with your business—you can even deactivate (and stop paying for) SIMs as needed.

All-in-one IoT dashboard
Even with multiple carrier profiles on one SIM, you’ll never have to juggle multiple connectivity management portals. Our intuitive IoT dashboard lets you monitor, automate, manage, and troubleshoot all of your deployments from the same place. It’s a single pane of glass for all your IoT devices.
Multi-layered IoT security
Some connectivity components compromise your security and put your devices at risk of being hacked or misused. Our tech bolsters your IoT security, giving you the ability to limit your device’s data consumption, encrypt your communications, secure connections with VPN, and more.
Simple API integration
Our REST API and rich integration guides empower you to bring connectivity data to your ESP, ERP, and CRM solutions. Using your preferred programming language, you can easily integrate our platform to manage, monitor, and control your devices from the tools you already have.

Multi-carrier SIM card FAQs
A multi-network SIM card is a piece of hardware that stores a Subscriber Identity Module (SIM) which can access multiple cellular networks. The term is a bit ambiguous and could technically refer to a SIM that has access to at least a handful of carrier networks via roaming agreements, or to a SIM with access to hundreds (like emnify’s SIMs). Generally, it refers to the latter.
Depending on the context, someone could also technically mean to imply that a SIM has profiles from multiple carriers. Our SIMs can connect to hundreds of networks and switch between carrier profiles as needed.
Every SIM stores a profile that associates it with a specific cellular network operator which gives access to the provider's network and the networks of any operators they have roaming agreements with. When a device attempts to connect to a cellular network, the operator authenticates the SIM, checking whether the “subscriber” (you) is authorized to use the network. If your device crosses a border or gets deployed in a new country, the multi-carrier SIM attaches to a local carrier it’s authorized to access.
Some SIMs, like emnify’s, can also leverage advanced cellular technology like Multi-IMSI and eUICC to access more networks and change carriers in more situations.
With traditional SIM cards, there’s no way to change the carrier associated with your SIM—you have to get a new SIM card from the new carrier you're switching to and insert it into the device manually. However, the eUICC made it possible for SIMs to store multiple profiles and applets, opening the door to a process called remote SIM provisioning, where you can change the carrier associated with a SIM Over-the-Air.
Normally, with M2M SIMs, this is an expensive, time-consuming process. Changing carriers via eUICC requires the carrier you’re leaving to build an integration with the carrier you’re switching to. But using our Multi-IMSI applet, your SIM can bypass this process by storing multiple subscriber identities and simply pausing or resuming the contract the subscriber identity has with the carrier.
Sound complicated? It’s not on your end. Our Multi-IMSI applet changes the carrier associated with your SIM automatically as needed. Whether you need to comply with regulations or simply want to optimize for costs or service, the change happens behind the scenes, and you’ll never have to lift a finger.
