[Q] Gear S as daily driver, adding contacts issue topic

Last year I decided to downsize from my Galaxy S3 to a basic flip phone. I still have my original Galaxy S (sch-i500 Fascinate [CM 10]) that I use as a WiFi media player (love the Wolfson dac), check my email, and offline GPS from time to time. I don't regret my decision as crazy as it sounds (also gave up my Verizon unlimited data) but I'm saving per month and also feel more connected to the world around me. The only thing that I absolutely hate about my crappy LG flip phone it texting with it. T9 texting is so hideous! I've played around with the Gear S at a Verizon store and concluded that texting on the Gear S is much more superior to T9 texting on my flip phone and would like to use the Gear S as my main phone. It's my understanding that the Gear Manager app is needed to load apps and sync to the Gear S and I realize that I'll need to mod my original Galaxy S even more to get Gear Manager to work, but if I can't get it to work I figure I could just use my parents Galaxy S4's to load apps onto the Gear S.

The only other real problem I've read about on the Gear S forums that concerns me is the matter of Contacts and that with the Gear S itself you can't manually add contacts but have to use a Galaxy phone synced with Gear Manager. Before I got rid of my Galaxy S3 I backed up my contacts to the micro sim card. Couldn't I just trim down the micro sim to a nano sim and have all my contacts added to the Gear S that way? If that won't work what about sending contacts to the Gear S via bluetooth without Gear Manager?
