Re: SMS on CDMA USB/PCMCIA Data Cards

[Dinesh Shah]

Dear Daniele,

Thanks for your detailed response.

I have initiated communication with Qualcomm and Huawei to get their  
proprietory Extended AT command set. Huawei has already declined to  
part any info. I am still waiting for Qualcomm to respond.

In any case, now I will go ahead with my project in Nokia and deal  
with CDMA data cards later. However, they are more attractive in term  
of cost and other factors.

If all talks with OEM fails, I will start reverse engineering their  
windows software.

Thanks once again for all your help and support.
With regards,
