4G modem/router

[Russinating]

Can anyone recommend a 4G modem/router that takes a SIM card for an office? Seems like a lot out there and no idea about them all!

have used this is anger with an 02 dongle

just check the list of supported dongles (it's not long) and ensure you have the latest firmware
