It is much too early for any leak to be real and not completely made up. A new watch wouldn't even likely be announced until WWDC (June/July 2018) or later.
I've always bought devices outright so that's not a concern.
The cellular technology that Apple would use in the current series 3 watches would be the same in the series 4. It's just a software based sim (an e-sim) so once it's supported, it should always be.
Is there any update on when and if Rogers will support Apple Watch with LTE ?
So I just upgraded my Apple watch to be able to receive calls/texts without my phone around and now I am looking for a new plan with a new provider. It's very unfortunate, as I am happy with the service I am getting with Rogers.
I don't understand why you think it's "beyond" you to figure out why people want to switch because of the Apple Watch issue. Have you ever tried jogging with an iPhone 7 Plus as opposed to a Watch with AirPods? We would also like to be able to receive urgent calls during our workouts from our family at the same time. Balancing both requires us to have a Watch. The ability to pick up arrhythmias like atrial fibrillation during workouts is a nice feature to have as well.
The Watch is very important to some of us and you can add me to your list of switchers if Rogers does not offer this within a month or two at most. My self and my wife will be jumping over to Telus or Bell.
