We use a 4G smart hub due to poor broadband connectivity. We also have O2 iPhones which we have used successfully for 9 months with the hub to make WiFi calls (no o2 mobile signal here).
Last week, we could no longer access WiFi calling. Same for both handsets. Reset router to factory but no different. If we access other routers we immediately can access WiFi calling again, so the handsets work but no longer with this router.
Before anyone says … it worked so WiFi calling can be accessed via the 4G smart hub router. Phones work on other routers so not the phone or their settings. Routers has been reset. Router has not been adjusted or moved. We can still fully access the internet but cannot switch to WiFi calling anymore.
Can anyone help beyond the usual generic responses (reset router; switch phone to airplane mode; turn off and on WiFi calling on the phone etc). Thank you for any insight as we desperately need phone access via WiFi calling.
