I've got a fairly new Android phone (Nexus 5). I know 3-way calling (conference calling) works well because I used it a lot when I was on T-Mobile in the USA. Now I'm in Canada and I've got Koodo SIM but every time I try to add a call in Alberta the first call drops. I'm thinking this is a feature that Koodo doesn't offer? Maybe I'm wrong. Has anyone made a successful 3-way/conference call using an Android phone with Koodo?
