I am a potential customer interested in getting more information about your product.

I have GSM test phones (that work in modem mode) with valid T-Mobile & Cingular/ATT SIM cards.

Would your product let me send a Class 2 SMS(SIM specific) from one test phone and receive it on another one of our test phones?

Hi,

I think you might have called in and talked to Lisa Smith earlier this week.

You can definitely use NowSMS for sending SMS Class 2 messages. But things are a bit funny in the US.

I have a test system setup with a couple of T-Mobile USA SIMs and can confirm that I can send a class 2 message from one T-Mobile USA SIM to another ... and it is received with the correct message class set.

I don't have a Cingular SIM to test with, but based upon what I have seen in the past, I would not expect to see the class attribute preserved if the message is sent cross operator (i.e., T-Mobile to Cingular).

Outside of the US ... yes, I would expect the message class attribute to be preserved, even going cross-operator. It is just that the cross-operator connections in the US often lose any GSM specific attributes, even when going between GSM carriers.

My suggestion would be to try it ... the web interface has a button selection for setting the message class.

I tried sending Class 2 SMS over the T-Mobile network as you suggested.

Surprisingly, the SMS was received with the Class 2 PID & DCS fields intact, but it was received with user notification like a regular SMS though. Class 2 SMS is supposed to be received with no user notifcation though

Did you have the similar experience? Was your Class 2 SMS received with user notification on the receiving end?

Hi Mahesh,

I'm not an expert when it comes to the intracies of interfacing with SIM data and applications.

But it does seem to me that if you just send an SMS with the PID & DCS values set to indicate SIM data download ... but the data itself is not valid ... then most phones will just treat the message like a standard SMS.
