Mains powered
Built for continuous use in an office, home, shop, remote building or other fixed site rather than being carried around.
4G and 5G routers designed for offices, home working and permanent sites. Insert a data SIM for mobile connectivity, connect important equipment by Ethernet, and choose business connectivity options such as fixed IP where required.
Portable Mobile WiFi is built around mobility and battery life. Office and home SIM routers are usually mains powered and designed to sit in one location, with stronger networking features, more wired connectivity and options better suited to permanent installations.
Built for continuous use in an office, home, shop, remote building or other fixed site rather than being carried around.
Depending on model, multiple Gigabit or multi-Gigabit LAN/WAN ports can connect wired devices and network switches.
Selected models offer WiFi 6/7, mesh compatibility or external antenna connections for larger spaces and more demanding sites.
Business-grade models can add features such as VPN, remote management, dual-SIM resilience, firewall controls and WAN failover.
An office or home router can do more than broadcast WiFi. Ethernet ports let you connect devices that benefit from a direct wired connection, or link the router into an existing network switch.
A SIM router can provide the internet connection while still working like a conventional office or home network router.
For some business applications, ordinary mobile internet is not enough. A fixed public IP can make it easier to reach equipment remotely and support applications that expect a consistent IP address.
Both use SIM cards, but they are designed around different jobs.
| Feature | Office / Home SIM Router | Portable Mobile WiFi |
|---|---|---|
| Typical use | Permanent office, home or site connectivity | Travel, temporary connectivity and on-the-go use |
| Power | Usually mains powered for continuous use | Usually battery powered for portability |
| Ethernet | Multiple LAN/WAN ports are common | Often none or limited, although premium models can include one |
| WiFi coverage | Designed for a room, office, home or wider site; mesh options on selected models | Designed around personal or small-group portable use |
| Fixed IP | Can be paired with compatible fixed-IP SIM services | Usually not the main purpose of the device |
| Broadband backup | Selected routers can combine WAN broadband with cellular backup | Typically operates primarily from the mobile network |
| Advanced features | VPN, firewall, remote management and dual-SIM options on selected business models | Generally focused on easy portable connectivity |
Choose a SIM router when the premises needs something more substantial than a pocket hotspot.
Primary or backup connectivity for teams, PCs, phones, printers and other office equipment.
A dedicated connection for home offices where fixed broadband is slow, unavailable or needs backup.
Connect recorders, cameras and monitoring equipment, with fixed-IP options where the application requires them.
Keep payment terminals, tills and connected systems online at shops, kiosks and temporary retail sites.
Use 4G or 5G where fibre or good fixed-line broadband is difficult to obtain.
Use a suitable router and SIM as a secondary connection when the main broadband service fails.
Portable Mobile WiFi devices are designed to travel and normally prioritise battery life and compact size. Office and home routers are usually mains powered and focus more on Ethernet connectivity, wider WiFi coverage and permanent-site features.
Yes, on routers with LAN ports. The number and speed of ports varies by model, so we can help match the router to the equipment you need to connect.
Yes, with compatible fixed-IP mobile data services and the correct configuration. A fixed IP is provided by the connectivity service rather than automatically by every router.
Yes, where mobile coverage and the selected data plan are suitable. Some businesses and homes use 4G or 5G as their primary connection where fixed broadband is unavailable or performs poorly.
Yes, selected routers support WAN and cellular failover. The exact setup depends on the router model and how your existing network is configured.
Company Mobiles can discuss data SIM options across O2, Vodafone, EE, Three and multi-network services, subject to the product, coverage and tariff required.
