SIM card in router limits

[DavidWB]

As a family, we currently have 3 Smarty sims in mobile phones, and are very happy with the service and reliability. I am considering changing our broadband usage to a sim router, and a SMARTY sim seems an obvious choice, but I have concerns over the 8 device tethering warning stated in paras 5.15 and 5.16 of the T&C's. We are not massive data users, and the current 200 Gb/ month offer should be more than enough, but have up to 12 devices that could link to wifi, including our phones, Echo devices and smart TV. Is this likely to trigger a suspension/ termination?

@DavidWB I think that the T&C's 5.15 refers to using the Unlimited plan rather than your 200Gb plan. Surely, if you tether a lot of devices all using data, then your 200Gb will go that much faster; it is hard to see that as unreasonable use. 

If you are thinking of moving to the Unlimited plan, then you may run into problems if your data usage becomes heavy. 5.15 as you say warns that you should only use up to 8 devices and also specifically states that you should not rely on the service as a broadband replacement.
