Hi all,

I'm looking for an app that will send the location of a WP8 phone by SMS when mobile internet is not available.

Even better if the app could respond to a SMS received.

I know there where apps like this for Windows Mobile 6.5 but haven't seen any for WP8.

Thanks,

JW

This is impossible for two reasons...

1) There is no API which would use services that cost you money on your behalf (well, except data connections, but when you turn it off, it stays off). Consequently, there is no way for apps to legally intercept SMSes.

2) Some mobile operators do not allow the usage of such apps, to prevent traffic overflows.


You can, however,. find apps which allow you to send location through SMS manually.

Well, no way for a third-party app in the store. It's actually possible with homebrew on interop-unlocked phones. I've considered writing a demo app for how to intercept and send SMS programmatically.

Wouldn't help unless you have a phone that can be interop-unlocked though.

This is not correct. Windows phone uses SMS intercept as a backup to trigger app download, location reporting, and remote ringing (aka find my phone) with capabilities ID_CAP_SMS_INTERCEPT_AGENT and ID_CAP_SMS_INTERCEPT_RECIPIENT. The API function to send an SMS is, logically enough, SmsSendMessage (http://msdn.microsoft.com/en-us/library/ee498244.aspx). There are no laws that prevent intercepting SMS messages on the device to which the SMS is sent.

That's a CE API, not an NT one... it may be present on WP8 (un-modified, I mean; obviously they have *some* API for sending SMS) but the documentation you linked may be incorrect. In any case, I would be very interested to know what capability is required to use it... that would allow a wholsesale replacement of the built-in SMS utility, potentially (on capability-unlocked phones).

However, what I suspect mcosmin222 meant is that there's no such *public* API and no app that did that would ever be allowed into the store...

Thanks for all the replies. Gave me some more insight.

In the new Lumia Black software, there is this "Driving Mode". There you have the option to have auto text replies to incoming calls AND text messages.

So it looks there is some kind of API but probably not publicly available?

Legal way in the context of the marketplace.
There's legal APIs and illegal APIs, and anything which has to do with SMS (aside from Sms compose task) is illegal on the marketplace for the average developer.

There is obviously an API which allows WP8 to send SMS, but that is contained only for internal system use.

The app that might be of use to find which hidden API calls could be used to intercept SMS messages is the Nokia's "call + SMS filter" (http://www.windowsphone.com/en-us/st...7-c6ab1d971357). But the unknown is whether or not that would work on non-Nokia's or could it work on all WP8 devices (I'd install it on my Ativ S to copy its content, but unfortunately it's FS access has been blocked with me installing GDR3, the developer 10521)...

Is it possible to develop an application by using the SMS to get the location?
