I don't know if I buy that. Unless all 5/5S users with a watch are having this issue. I actually wanted to purchase my 6S, using Apple Pay on my discover to get 10% back. Can't really do that if I can't add it to my current setup.
How to Add Your Discover Card to Apple Pay
- On iPhone® just open the Wallet app and tap the plus sign. From there, follow the onscreen instructions.
- On Apple WatchTM, open the Apple Watch app on your iPhone and select "Wallet & Apple Pay," then tap "Add Credit or Debit Card." From there, follow the onscreen instructions.
- Have the Discover Mobile App? You can add your Discover card to Apple Pay and manage your devices right from the app.
I was having the same problem. Called Discover and they insisted that I CANNOT add a Discover Card to my Apple Watch via an iPhone 5s. Called back again last night and told them I was using a iPhone 6 (so we could get past that)…still no help.
Today, I found the solution:
UNPAIR your Apple Watch from your iPhone (after doing the iOS and WatchOS upgrades) and re-pair it. You can use a backup so you don't have to set everything up from scratch (you will see that option when you go to re-pair your watch).
Once I did that, I was able to setup my Discover (More) card on my Apple Watch via my iPhone 5s…no problem.
I called Discover back this morning and told them the solution…hopefully they listened and entered it into their database so others aren't given bad info like I was yesterday.
