I've had to edit this answer a few times as the services I initially recommended have gone out of business. I believe that the new industry leader is Twilio, they have an excellent API and reasonable prices. Some alternatives worth considering are Tropo, Plivo, and Nexmo. I've been using IMified for a little while to do stuff similar to that and I've found ...

I had a friend who managed to implement this via email. I believe he did it exactly the same way this site recommends: T-Mobile: phonenumber@tmomail.net Virgin Mobile: phonenumber@vmobl.com Cingular: phonenumber@cingularme.com AT&T: phonenumber@txt.att.net Sprint: phonenumber@messaging.sprintpcs.com Verizon: phonenumber@vtext.com Nextel: ...

I've been using Twilio for voice and I've been quite impressed. I'm sure their SMS system isn't much different. This will allow you to send to any carrier without knowing the email address to send to (as I've noticed they change over time).

This is for sending only, but I've used Penny SMS for a project and had good luck with it. If you happen to be using Ruby, check out the penny_sms_muncher gem.

Other two options I've considered in the past: Skype API Send and receive SMS using new Skype API. I guess Twilio is cheaper, but Skype is available in more countries (if you want to receive SMSs) Plug a phone to your server If you live in a country (like Argentina) where SMS gateway companies charge a lot, you may find it cheaper to buy a phone and plug ...

Check into UptimeRobot http://www.uptimerobot.com It's free, offers HTTP and ping monitoring every 5 minutes with email, text and RSS notifications. To my soon to be former webhost's chagrin, it's very reliable with uptime monitoring logs and past event tracking.

(I work for Twilio) Twilio meets your requirements, with the following caveats: We support short codes with the same simple API http://www.twilio.com/sms/short-codes Opt-in and opt-out capabilities are left up to your application logic We have the cleanest API of any gateway I've used (I was in a similar situation as you prior to working here so I have a ...

I would recommend looking into the two way api provided by http://www.world-text.com/.

I've written such a two ways SMS system using Vidicom UK as the SMS provider (not sure if they are still going). Basically they have an HTTP based API where you can send and receive SMS messages. It's too complex to explain in detail, but in essence I had two database tables, one for incoming messages received from the gateway and another one for outgoing ...

Try a google search, the exact phrase you will be looking for is "International SMS Gateway". We also use twilio for a couple apps and have to say nothing beats their level of support and developer friendliness. Also contact twilio for a reference. I spoke with them once about SIP programming and they referred me to some great companies. You can also ...

If you want an affordable bulk SMS provider, with a developer API you could use www.SourceSMS.com - they offer international coverage, and they have scripts you can simply download and integrate into your website.

mon.itor.us and SiteUptime have free/ad-supported plans. Check are only at 30-minute intervals however. They both have plan upgrades which measure at 5 minute intervals and are cheaper than Pingdom, so you might find a reasonable cost/benefit trade-off.

http://aremysitesup.com/ offers a free plan with 15 minute interval checking, or a paid plan (from $5.42/month) for 5 minute interval checking. If you're just monitoring one site, pingdom's free account offers 1-minute interval checking -- you just need to login once every 90 days to keep it alive: https://www.pingdom.com/signup/free/ (If you're monitoring ...

There are many SMS services that will allow you to set the originator to your Google number. If you are planning to send to the US, then this is different because the US carriers require to certify the originators (in most cases) so the end user can also opt out, request information about the service, etc, but if you are planning to send SMS to other ...

I use was it up (free), and they've always seemed to catch my downtime pretty quickly. I'm going to pump the emails into PagerDuty (not free) to send SMSes as soon as I get a chance.

The only non-sketchy SMS ad network I know of is 4INFO. They also have a program called AdHaven Mobile, but I'm not sure how it's different from their ad service for publishers.

Twilio costs $0.01 per message (Non-US is in private beta). As for adverts, I just googled SMS adverts and got a load of companies that sell advertising. Maybe get in touch with a few of them and ask them.

A provider supporting both MO & MT messaging (Mobile Originating and Terminating, respectively) is Clickatell. Based on your intentions, I believe you're looking for long code support, which Clickatell definitely does. Related reading that will assist: Clickatell's API documentation, including HTTP/S, FTP, SMTP, etc. Clickatell's "callback" ...

Another option is to use PHP's mail function and a list of carrier's email servers, like so: Make an HTML form on a PHP file, <select name="carrier" style="width: 130px" > <option selected="" value="1">Verizon Wireless</option> <option value="2">Alltel</option> <option value="3">Boost Mobile</option> <option ...
