Pebble recently gave Verizon iPhone customers the ability to text for their iPhones from their wrists (sporting Pebble, of course) on iMessage, but AT&T Pebble customers can brag that they had iMessage texting compatibility first in the US. Pebble recently updated its smartwatches to allow quick replies for iPhones, but Pebble OS firmware v.3.12 requires carriers to enable compatibility (likely a software update on smartphones). Now, however, after the first two US wireless giants get iMessage compatibility, T-Mobile becomes the third wireless carrier in the US to receive iMessage texting compatibility on Pebble smartwatches. Pebble is calling this "iOS Text Reply for Pebble."
IOS Text Reply for Pebble is now available in the US for AT&T two-year contract customers (no prepaid customers), Verizon, and T-Mobile, of course. While Pebble customers on other carriers have yet to receive the update, however, Pebble has more work ahead for its iPhone compatibility status. The company has said at Kickstarter that it is working on bringing iOS Email Actions that let you "reply, archive, and delete emails received from your iPhone," and this program is now in beta mode. It's not yet ready for public release, so maybe more US carriers (Sprint and US Cellular come to mind) may join the iMessage texting party before too long.
Pebble's smartwatches all run via Bluetooth, so users can reply only if their smartwatches are paired to their smartphone(s). With that said, actions done on the smartwatch, including the new iMessage texting, will be treated as though they're being performed from the iPhone rather than your Pebble smartwatch (standalone devices that run 3G or 4G cellular connectivity can send messages and reply on their own without smartphone/Bluetooth pairing).
T-Mobile customers, go ahead and grab that update on your iPhone (then pair your Pebble smartwatch with it). Have you tried out the new iMessage texting capabilities? Like what you see? Do you long for more texting capabilities, or are you just happy for now that you can finally text from the wrist?
