Texting android phones on the Apple Watch 4 with iPhone not near by
Is there a way I can send texts and receive texts from android phones on my Apple Watch 4 when I leave my phone at home
Apple Watch Series 4, watchOS 5
Question marked as
SMS texting requires an iPhone more sophisticated cellular radio.
If you have GPS only Apple Watch and are away from your iPhone, then you can only do WiFi calling (which does not support SMS texts), assuming your carrier even supports WiFi calling.
If you have Cellular Apple Watch, the cellular radio does not have all the bells and whistles of a cell phone radio (size, power, cost constants), so the Apple Watch always uses the iPhone's cellular radio for SMS texts.
If your Apple Watch can find your iPhone on the network, it will still do SMS texts, but the 2 have to be able to speak to each other.
