I'm sure this has already been posted somewhere, but when I scoured the web and the forums I did not find a simple way to send SMS messages from the N810.

You need an email that you can access from your N810 in order to do this. It is probably best to make a new email account so that you don't get spammed with texts.

Step 1: Get to your email account either through
A) Setting up your mail account in the Mail application.
B) Logging in on a webmail.

Step 2: Find the address of the phone you are trying to text
"number" is the ten digit phone number

Alltel: number@message.alltel.com
AT&T: number@txt.att.net
Metro PCS: number@mymetropcs.com
Sprint PCS: number@messaging.sprintpcs.com
T-Mobile: number@tmomail.net
Verizon Wirless: number@vtext.com
Virgin Mobile: number@vmobl.com

Most others can be found HERE

Step 3: Compose email and send it to the address
Remember that cell phones have character limits to it.

This way is very crude, however it does not require any installations or programming. If you use the mail application, it will alert you that you got new mail when your text is replied. If you use webmail, you well have to recheck your mail every time to see if you have new texts.

Ya, it can be annoying at times, but it does work.

By the way, this strategy can be applied to most other gadgets that use the internet.

actually, its easier to use the built in chat client. Make a gtalk field entry for the contact you want of +15556667777@sms.talk.google.com. That way you can IM through texts and you dont have to wait for or keep refreshing your email.

Is this something limited to US networks?

Yep. US only for now. Mentioned here:

(look for "Text Messaging (SMS) in Chat")

This was more of the fire proof way of doing it.
Its also one you can just pick up and use it somewhere else.
I have multiple internet tablets so it works rather well for things that don't have those options.

this method is free for the receiving party, right? i just want to confirm because i have seen some things similar but it charged the receiver...total bummer lol

hello all,
i have been using this site for a good minute know and I thought I got it off here.

the site on this page is way better.

In every case I've seen, it costs for both the sender and receiver of a text. So whoever you send a text to is gonna get slapped with a charge.

in the US you pay for incoming minutes/texts, unless you've got an option for incoming minutes/texts (that is, you pay them anyway, but at a cheaper price).
that is the reason why this methods work in the US.

The receiver get charged standard txt messaging rates. Same as if you send an email as per the first post or just send them a txt from your phone.

Courtesy has always dictated asking if it's ok to communicate w/someone via txt.
