SIM card for 4G and 5G routers
Updated
A 4G or 5G router needs a data SIM that allows router use, works on the router’s frequency bands, and matches how the site will be reached: internet only, a static public IP, or private delivery into your network. Data use varies more than for any other device, from a few hundred megabytes for a payment kiosk to hundreds of gigabytes for a site with staff and video.

Key points
- Router use allowed. IoT SIMs are made for it; many phone plans forbid or throttle it.
- Bands. Check that the router’s 4G or 5G bands match the networks of the country.
- Reachability. Choose between internet only, static public IP and private delivery before deploying, not after.
- Backup links. Idle backup SIMs cost little when they share a prepaid data pool.
Typical sites
| Site | What travels over the router | Main need |
|---|---|---|
| Payment kiosk or vending machine | transactions, telemetry | private delivery, small data |
| Construction site or temporary office | staff internet, cameras | data volume |
| Vehicle (bus, van, boat) | passenger Wi-Fi, telematics | multi-country coverage |
| Shop or branch, fixed line backup | everything, only during outages | shared data pool |
| Remote equipment (pump, substation) | supervision, maintenance access | private delivery, no internet exposure |
Set up
- Insert the SIM with the router off.
- Enter the APN in the router’s mobile settings.
- Lock the radio to 4G or 5G if the router allows it, to avoid falling back to networks being switched off.
- Choose the delivery: internet, static IP, or private delivery to your network.
- Watch usage in your account or through the API, and set an alert before the data runs out.

Frequently asked questions
Can I put any SIM card in a 4G router?
Physically, yes if the size fits. In practice, the SIM must allow data use in a router, work on the router's frequency bands, and come with the APN settings the router needs. Phone plans often forbid router use or limit it.
Do I need a static IP for a 4G router?
Only if something on the internet must open connections to the router or to devices behind it. If your own network or cloud is the only place that needs to reach them, private delivery is safer than a static public IP.
Can a 4G router be a backup for my fixed line?
Yes. Many business routers switch to the cellular link when the fixed line fails. A prepaid data pool shared by all backup SIMs keeps the cost low while the backups are idle.
