Be gentle, first deal post here. A store employee mentioned this to me and I could not find it here nor online.
T-Mobile has a promo going on allowing you to get a second wearable/tablet/sync line free when you add a wearable line or tablet line. You don't have to buy the watch or tablet with T-Mo, just add existing devices.
E.g. I added a smartphone line to the Apple Watch 4 and got a second line for a tablet for free. Wearable line is $10 after autopay ($15 otherwise) and tablet is $20 for unlimited, so you would still pay $10, but there is also a 2GB LTE tablet plan for $10/month which is free when you add a watch for example. You can mix and match wearable, tablet or sync devices as you like. In store and online. I ordered via chat.
- Update: The document number for the BOGO promotion is 457861 (for CSR)
- Stacks with other promos if you buy devices from T-Mo.
- Seems to work with various plans: One, Military, ...
- Buy one get one lines for (you can mix and match as well)
- wearable devices (smartwatches $10 after autopay)
- syncdrive lines ($10 after autopay)
- 2GB LTE tablet lines ($10 after autopay)
- Mobile Internet (hotspots)
- Tablet lines (unlimited $20 after autopay)
