Can I put any SIM in my 4G router?

In general, 4G routers are designed to work with SIM cards from specific mobile carriers or providers. The compatibility of SIM cards with a 4G router depends on factors such as the network frequencies supported by the router and the carrier's network.

Before attempting to use a SIM card in your 4G router, you should check the following:

Network Compatibility: Ensure that the 4G router supports the frequency bands used by the carrier. Different carriers operate on different frequency bands, so compatibility is crucial.

SIM Lock: Some 4G routers may be locked to a specific carrier, preventing the use of SIM cards from other carriers. Check whether your router is unlocked or if there are any restrictions.

SIM Size: Confirm that the SIM card size matches the slot on your 4G router. SIM cards come in standard, micro, and nano sizes.

APN Settings: Depending on the carrier, you may need to configure Access Point Name (APN) settings on the 4G router for data connectivity.

If your 4G router is unlocked, supports the necessary frequency bands, and the SIM card is from a compatible carrier, it should work seamlessly. If you're unsure about the compatibility, you can check the router's user manual or contact the manufacturer's support for guidance.
