FrontlineSMS allows you to text message with large groups of people anywhere there is a mobile signal.

Duplicate messages being received.

Hi there,

I have just recently downloaded FLSMS version 1.6.16.3 and am testing it out before we start using it with some community radio stations in Zambia. It mostly seems to be working fine except that the occasional message received is being duplicated multiple times. This in turn triggers the sending of multiple responses based on the keyword that is in that text. In short, one message becomes 30 messages, triggering 30 responses, and my balance goes down a whole lot faster than desired!

Any idea why this is happening? I'm using a Huawei E1550 modem.

And whilst I'm at it, is there a way to change the currency of the cost estimator down in the bottom righthand corner?

Will appreciate any advice you can offer! Many thanks.

(In case it's not already apparent, I'm not fantastically tech savvy, so the more layman's speak you use, the better)

Hi Kate,

In my opinion, your problem sounds to be comming from ISP. It same in the phone when it is not connected to your Laptop yet. I had the problem with my fone inthe past. All the time i was smsing this one was doubled in the receivers. Try to be check out your sms parameters of the modem you are using. You can also, restore factory settings may be it gonna solve your problem.

I'm sure it is not FLSMS issue.

Regards;

Hello Kate,

this is weird indeed.
First of all, can you confirm this doesn't happen with your SIM card when it is inside a common mobile phone? And have you tried using your Huawei modem on another computer and check if messages are being duplicated as well?

Regarding the currency symbol, it is currently attached to the language you are using. FrontlineSMS v1.7 will let you manage your currencies easily.

Best of luck,

Morgan

What a helpful community! Thanks Morgan and David. Can confirm that it doesn't happen with the SIM when inside a normal phone (it's my regular phone SIM incidentally). I will try test out the use of the modem on a diff computer to see if that changes anything. But as I said, it's only happened with that SIM twice in the 10 or so times that FLSMS has received a msg from it, so there's no obvious pattern.

Will also check modem parameters as you suggest David (as soon as I can figure out how on earth one does that... ;)

Incidentally, I notice in the phone tabs that the status of the modem is listed as "duplicate connection". Not sure if that signifies anything important.

And thanks for the currency info Morgan. Will look forward to v7.

Will let you know when/ if the issue reoccurs. Have sent 7 texts in the past 10mins and so far so good.

Hi Kate,

do you see the "duplicate connection" message on one single line?

It might be worth checking if in some cases, your device is not recognized twice and then triggers an action twice for each text. If you happen to see two lines referencing the same device, try disabling one and see how it goes.

Hope that helps a bit.

Duplicate connection is only in the non-working devices. In windows when ejecting the USB stick / modem there are two entries - one is a data store containing e.g. user manual etc and am guessing the other could be the actual modem? On the working devices, the status is 'Connected'.

I can't see anything that needs to be disabled.
