I think the title is self-explanatory. I have a cell phone but it is voice only and, from what I have seen I would not to try messaging from those touch screen keyboards anyway. I have Skype on my PC.
You can do it through email if you know the other person’s carrier.
You can send SMS from Skype to many (most?) phones, but you have to pay.
yahoo mail lets you send sms messages right from your email account.
Google Voice lets you send and receive text messages. You can even forward the texts to your cell phone if you like.
This site http://www.makeuseof.com/tag/email-to-sms/ lists MANY of the carriers and the Email address to use.
If you use Gmail, the Chat client on the left side of the window can send/receive text messages.
I’ve used this a couple of times and it works fine:
I send text messages using Google Voice every day and can do so from my phone, tablet or computer. Messages are sent to a mobile recipient from my Google Voice phone number. This only works in the U.S. and Canada, however (and can only be delivered to devices in those countries).
Can anyone show us a list of the email addresses for various carriers?
I remember once doing this. The email for an AT&T phone was addressed to 9995551212@attwireless.com or something like that. The subject line was blank, and the text of the email was sent as the text message.
Is this what you’re looking for?
What about *receiving *them?
Google Voice receives from individuals, but not (some/many) businesses. I need to be able to receive codes from my bank but do not have texting on my plan.
