TdmaSms
 

North American TDMA networks (e.g. AT&T Wireless, Rogers AT&T) have recently gained the ability to send as well as receive SMS (short message service) messages.  Unfortunately, the phones that support the TDMA network (IS136) differ than those supporting the GSM network in Europe, so the SMS applications for Pocket PC don't work with them.

We've spent a fair amount of time investigating how the TDMA phones work, and have come up with a simple "Send SMS" application to send an SMS message from a Pocket PC connected via serial cable to one of these phones.

TdmaSms is known to work with:
  • Ericsson R278d (Rogers AT&T)
  • Ericsson 1228di (Rogers AT&T)

...and is known NOT to work with:

  • Nokia 5165
  • Nokia 5125 

 

If your phone is not listed above, you can test it by attaching it to your Pocket PC using a serial cable (which you can usually get from the same place you bought your phone), starting TdmaSms and selecting File->Sniff Phone.  TdmaSms will report if the phone is capable of receiving and sending SMS messages using the IS136 standard.

Other Notes

  • TdmaSms is free but is supplied AS IS and without any support or warranty.  We don't promise that it will work with your phone or network carrier.
  • Since this is basically experimental software, TdmaSms MAY NOT be included in any CD collections or redistributed on any web site
  • If you decide to try this program, please send us your testing results.  Specifically, if it works or doesn't work for you, the phone you tried it with and your carrier, and any other oddities you encounter.
