Most of the people I instant message with are not people I know IRL and thus don’t friend on Facebook which has IRL info on me. Many of them I also don’t have phone contact with. I never understood the point of having SMS in Hangouts, to be honest. I already have perfectly good apps for that and would like my IMs to be handled like IMs.
There are other ways to do SMS on PC. There are other ways to do IMs, too, of course, but none of my friends are on them and they tend to be a) bad and/or b) not as convenient on a phone.
I use MightyText, which is a solid multi client syncing text app that lets you read and reply via pc program or web app. It also supports driving phone notifications to the pc, if you want. Free, but paid if you send a lot of messages…
I just use the basic Google Messenger SMS app. I like it. Pretty basic. For SMS from PC, I use Pushbullet, which I pay for. It’s $40/year. So cheaper than Mighty text, and I prefer the aesthetic and functionality over MightyText.
Airdroid is a good solution at home. If you’re at work, or traveling, it can be a royal PITA to get the connection working through corporate firewalls.
Some friends are on iMessage; is there any way our group messaging can stay in one thread? As it is with the Android sms app, they keep getting individual replies.
Ha. Yeah, at this point I wouldn’t touch a Google chat product with a ten-foot pole, even if they paid me to. There are just too many better alternatives to spend any time on left-hand, unsupported solutions such as what comes out of Google in this respect.
I have friends that like GroupMe, but I don’t care for it. WhatsApp still seems less obnoxious than Facebook Messenger, but if your concerns are about privacy, they’re not an option since FB owns them. Beyond that, I dunno, but those are the two that I still get dragged into by other people.
