How long until text messages cant be delivered?

22-08-2011
Hi all,

I have an SMS camera of which sends a text message and a picture message when someone goes within 5 metres of the sensor. I intend using this when im on holiday for security..

A lot of the time I wont have my mobile on so im hoping I can turn on the phone every 24 hours or so to see if anyones been snooping around.

I have tested it with the phone turned off, triggered the camera then turned the phone on 24 hours later and 12 hours later but the messages dont arrive...it works fine when my phones on

Ive tried it on tesco (o2) and Vodafone

Im in the UK...I can change networks if need be if I can find one that delivers messages 24+ hours later

Thanks

i thought any network would save sms messages from longer than that.

ive been on holiday before, where I didnt have any coverage.

when I came back into the country a fortnight later, and switched my phone on, they all came through

Would it not be easier to just leave the phone on all the time but set to silent?

That sounds like its not triggering/taking/sending the picture when the phone is off (are you sure its able to do that? I've never heard of a phone being able to switch itself on and take a picture when triggered by a sensor).

Its an MMS camera that sends picture messages when someone triggers it..it then sends 5 x pictures at .5 second delay to up to 8 phones...

Im away a lot where there isnt a signal and was planning on putting it in my workshop so I can see who breaks in..should it happen.

If I cant see it happening live i.e call the police etc then I would like to be able to see it when I go into signal area or turn the phone on.

Ive just tested it and its retrieved all the messages from 4 hours ago but would like it to be able to retrieve from about 24 hours back.

Theres one message I never seem to get of which is the camera status..this sends a report at 10am daily...I get it every time if the phones on and in a signal area but not when I turn the recieving phone off....its a 2 part message due to its length

Ive just tested it overnight..

At 11pm I turned off the phone, activated the camera and sent the same phone another text from the wifes phone...the text from the wifes phone has arrived but nothing from the camera..this was 8 hours ago and ive waited 30 minutes since turning on the phone.


Is it possible the camera is sending as a lower priority than the wifes phone or something?

Please help...driving me nuts

Attached (amongst other things) to every text and MMS is a validity period which tells the network message centre how long to keep trying to deliver the message. On a phone this can be set in the message settings. With equipment like your camera its normally set using a programming command (as you set the phone number).

By default, all the security equipment I've seen has a short validity.

Another possibility is that the messages ate being blocked. Can I ask what the SIM/tariff is? As many tariffs forbid the use if the SIM in automatic equipment/gateways etc.

Cant you get the MMS to send to your email address instead and check email on your phone when you are away?

I phoned up vodafone "technical" and Tesco "technical" today..but they couldnt give me any answers as to why when I turn off the phone, get the camera to send a message, get my wifes phone to send a message and get my works phone to send a message the wifes phone and work phone messages are picked up 9 hours later but the one from the camera has disapeared..all 3 I sent from and the phone im recieving on were tesco sims and ive also tried Vodafone

Has anyone any ideas on how I might get over this...the people who make the unit are not interested...maybe forward the text messages somehow so they resend but with longer validity period?
sinisterzane

Here is an e-mail ive got back from the manufacturer of the unit...


Regarding to the problem, it is not caused by our unit. our units sent out the SMS correctly,the problem is when sent out from our unit, the SMS will transport to the GSM Operator, how does the GSM Operator handle the SMS, this is based on the GSM Operator, not we can control it.

Ithink you can ignore that email. Its badly written, talks about SMS not MMS and how would they know that the unit is working properly without looking at it?

If you take the SIM out of the camera and put it ina phone, send some messages, do they arrive?

Are you sure that you can't change the validity period?

Forum Member 'bowlingo' starts off a thread then Forum Member 'sinisterzane" carries on the conversation as if they are 'bowlingo'.

Split personality, perhaps.

An interesting thread, nevertheless.

There are quite a few multiple registrations in here, doesn't seem to be policed like it used to.

Personally, it doesn't bother me unless its being used to disrupt the forum (see the Radio and Broadcasting forums)

Perhaps they think that receiving a message that you are being burgled 24 hours after the event is a bit pointless?

Not necessarily if it has a picture of the burglars on it, but I take your point. It would be better to be alerted to it straight away.

It takes pictures of the intruder so it would be a good thing to if anything have a picture of them trouble is you go into a area without a signal for more than 5 hours or your staying somewhere where you cant get a signal and have to go into nearest town (I go camping and have to go to nearest town each day) then you will be none the wiser

I cant see any command to change the validity period so it must be coded within the unit.

Ive just taken the sim out of the camera, put it in a phone and texted the phone with camera sim in it and arrived no problem.

I could also try the above but leave it for 5 hours and see but im sure there will be no difference..

Heres what I did last night again..

1) with receiving mobile phone turned on I trigger the MMS camera and receive message

2) turn off recieving mobile phone

3) trigger the MMS camera as of above step 1

4) send SMS message to the turned off mobile phone from my wifes mobile phone

5) send SMS message to the turned off mobile phone from my work mobile phone

6) send MMS message from another MMS camera (different make and poor quality) to the turned off mobile phone

7) turn on mobile phone 7 hours later..both SMS messages received and other MMS camera message received but no mms camera in question message recieved

It does sound like the MMS camera is either faulty or set to short validity. But you'll need to do the final test (which you didn't see the point of )

What is the make and model? It should be possible to find which module its based on and hence the command set.

I will give the 5 + hours test a go later on...

This is the chip it uses..

Here is the command manual..

http://www.auroramobile.ru/content/f..._atc_v1.01.pdf

on page 104 it looks like the message validoty period is set to 167 by default and can go up to 255...how on earth I can change this value is beyond me however as I only have the software that comes with the unit and I would be better off asking my cat how to do it than trying to comunicate with the Chinese "engineers" who made it
