Phone deregisteres from IMS

Trotty227 · ‎22-02-2020

Hi, whenever I remove my sim card my phone deregisteres from the IMS meaning I'm unable to use VoLTE and wi-fi calling the only way to fix it is factory reset my device. I'm using a Note 10+ 5G with UK sim free firmware (BTU) and help would be appreciated

Turning on airplane mode then wifi should force the registration rather than having to factory reset each time.

@Trotty227 Samsung support should have a fix: https://www.samsung.com/uk/support/

Another thread here with the same issue and the workaround I mentioned https://community.o2.co.uk/t5/Pay-Monthly/ims-registration/m-p/1292813/highlight/true#M176738

I suspect it's an issue with the way O2 wifi works.
