Are Sim only products suitable for use in 4G router?

Hi Folks - I live in a rural area with poor landline internet and planning to install an external antenna with internal 4G router as the main means of internet access. Are your sim only products suitable for use with the 4G router? I have done the coverage checks and I am in range of 2 of your masts. Thanks

@Unkle_Alb This is not O2. This is a customer community. I'm not sure if your setup would work, but you would also need a phone with O2 firmware that's suitable for WiFi calling. Perhaps @MI5 who is probably more familiar with this can explain it better.

As long as your router is unlocked to any network, an O2 4g SIM will work.
