At present, Mogotxt offers its service only in the United States. We have heard from some of our users that Mogotxt’s service also works in parts of Canada but we can’t confirm this.

We are working on expanding our service to Europe so please look for future announcements.

We have a lot of great new services and features in the works so please visit our site periodically to check.

If you have an iPod Touch and want to have SMS communications with another iPod Touch or computer, you can do this right now with our system from and to anywhere in the world. This will soon be true as well for the Nintendo DS, Sony PSP and other Wi-Fi or network-enabled devices.

As for access to cellular networks, our connectivity is limited to U.S. mobile carriers right now, although we have heard from our users that they can also receive our text messages in Canada. Just getting clearance for our service from U.S. mobile carriers was unbelievably hard because we pushed for and ultimately received permission to offer just about every SMS-related service possible. Where we differ from other SMS companies is that we offer a complete range of capabilities.

Because some of our investors are European, we are already looking at extending our services abroad. Please be sure to look for announcements in this regard soon on our website at (link)

Best.

I thought I would write a quick note to hopefully correct GigaOM’s coverage about Mogotxt’s new services.

You do not need a cell phone with a browser to use Mogotxt’s service. You can use any old cell phone and you can text using Mogotxt exactly the way you already text. We kept it simple.

Mogotxt is the first and only company to offer the following:

1. Free mobile-to-mobile texting to and from any cell phone, Apple iPod Touch or computer. (Very soon, Mogotxt will also roll out SMS service for the Nintendo DS and Sony PSP devices. A native SMS application for the Apple iPod Touch (also useable on the iPhone) is also in the works).

2. Free one-to-one text messaging that allows SMS messages to be easily sent and received among cell phones and iPod Touches. (As noted, other Wi-Fi or other network-enabled devices will be supported soon).

3. Free reply-all, group texting messaging (chat) with an unlimited number of cell phones and iPod Touches. (Again, other Wi-Fi or network-enabled devices to be supported soon).

4. A number of advanced features that enable users on the fly to (a) initiate and conduct up to five group chats simultaneously, (b) invite others to join ongoing chats, (c) join or quit ongoing chats, and (d) manage their mobile lifestyle via a brand new message management console.

Please try out Mogotxt’s services. We worked hard to make it both slick and very easy to use. It’s free. Peace.

Please write to us if you have any questions. We will answer.

This is not very useful unless you make your friends join this website (which probably ain’t going to happen).
