I wish to make a formal complaint to ID mobile.
I've spoken with other carriers Vodafone , O2 and EE. If you take out pay monthly SIM from them and provide your own mobile, you can use WI-FI calling features as it's part of phone features.
I spoke with Samsung store at Trafford centre and they confirmed feature should always be available.
I'm looking at taking this matter to OFCOM as I believe ID mobile is acting anti competitively by stipulating mobile must be purchased from ID mobile.

Firstly. We can absolutely shut down any sort of claims that we're withholding the feature from people simply because the phone was not bought from ourselves. In fact it's quite the opposite.
Some major network's make it so that certain features with a phone will only work when you use that phone with the network the phone was purchased from originally. Sure you might be able to get the phone unlocked once your contract is up, but a couple of features may be useless with another network (so this wouldn't just solely be with ourselves).
For us to withhold Wi-Fi calling would mean we'd be cutting down our potential customer base, given how important WiFi calling can be to certain buildings. So believe us, in this case, it's them, not us.
Have you been able to try another SIM (not just an iD one or the original network's SIMs, with the phone in question?). If it's working with other network's, but not ourselves, then it could potentially be that something within the phones settings is causing a conflict.
