Additional SIM card for shared data
Need an extra SIM card, data only SIM, or data card for your business? Whatever you call it, Telia makes it easy to get an additional card so you can share your business phone's data with other devices.
Data only SIM card: share data across multiple devices
Convenient
Works with most devices.
Secure
Browse safely from anywhere.
Affordable
Unlimited data for all your browsing.
Maximum speed, maximum security
With an extra data only SIM, you can make the most of your mobile data plan. Instead of sharing your connection between your phone and other devices, simply insert the extra SIM card into the device you want to connect.
It's incredibly convenient and more stable. But it's also far more secure than connecting your company's computers and other devices to public Wi-Fi networks. An encrypted connection is always safer than public Wi-Fi.
The extra SIM is for data only. If you have a mobile plan with a limited data allowance, you'll share the total amount between your primary SIM and your extra data SIM. If you have an unlimited data plan, you can use data without limits on both your phone and any other device with your extra SIM card.
Each business plan supports up to five extra data SIMs.
Browse securely on any device, anywhere
Use your additional data SIM in any compatible device for secure browsing on Sweden's best mobile network (according to umlaut 2025). Add extra data SIMs easily through your MyBusiness account. Note that additional data SIMs are included with our Unlimited Plus plan.
Major risks with public wifi networks
Free Wi-Fi at cafés, train stations, and airports is convenient – but we're so used to being constantly connected that we rarely think about the risks of public networks. Unfortunately, "public" often means "vulnerable."
Checking your email on the go using an open, unsecured network can be a costly mistake. And as you know, a cyberattack on your work computer doesn't just affect you. In the worst case, attackers can access your company's network, steal data, and bring operations to a halt.
With a separate SIM card, you can easily share your mobile data with your laptop or tablet and avoid logging into unsecured public Wi-Fi hotspots. If you typically tether through your phone, a dedicated data SIM is also a smart way to save battery life.
Unlimited data on all devices
An unlimited data plan from Telia is a smart business choice. Unlimited browsing on Sweden's best mobile network* gives you and your business a competitive edge. When work gets hectic and everything needs to run smoothly, it also provides added peace of mind.
The cherry on top is an extra data SIM that lets you browse as much as you want across all your devices. Our premium plan, Unlimited Plus, includes an extra data SIM (regular price SEK 249/month) along with many other benefits.
*Telia has Sweden's best mobile network according to umlaut's 2025 test.
What is a data only SIM used for?
Data SIM for router
Use your data SIM in a router to create a Wi-Fi network. With a portable mobile router, you can take your broadband connection anywhere.
Data SIM for iPad and tablet
A tablet without reliable connectivity is just a ... slab. Add a data SIM to your iPad or tablet and avoid the risks of public Wi-Fi.
Data SIM for computers
A secure connection on your laptop is especially important for work. If your computer has a SIM slot, you can insert your data SIM directly into the device.
