I’ve bought a PAYG sim card with iDmobile.
Now I’m looking for a second hand phone which will support wifi calling natively on iD. I’ve learned that iD runs on the Three network, so as I understand it: I can buy a handset that used to run on Three and it will have wifi calling enabled or possible to enable. Assuming that the handset is on iD’s compatible list. Correct me if I’m wrong.
My question is will this work with other ex networks? What situations will it work in and what situations won’t it work? For instance, if a handset is on both iD’s compatible list and another brand’s, will it work?
I suppose you will want to answer a specific question. Personally I think it would be helpful to have the above question answered for general information for other people. But the handsets I’m looking at currently are: Huawei P20 Pro and Samsung Galaxy S10e. I’ve already been to one local independent phone shop and tested my SIM card in a Huawei P20 Pro - wifi calling wasn’t available.
