    I'm trying to investigate which mobile carriers are interoperating with voicestream for SMS messaging. I originally accidentally posted this into a thread about SMS and Cingular, so I'm reposting the below here:

    For voicestream, I have verified that you can send SMS messages to:

    -other voicestream customers by entering the VS mobile number.

    -any email address by configuring the SMS app to have the correct email center number (500 i believe)

    and, yesterday i verified that you can also send SMS to

    -any *AT&T* customer (NOT just at&t gsm, but the whole at&t network) by entering the mobile number

    this last one is very nice, as it means there is some degree of interop between voicestream and at&t. note that i am NOT sending a message to an at&t phone via the email address conversion (xxxxxxxxxx@mobile.att.net), but just entering the phone number itself.

    what i don't know is how many OTHER carriers voicestream's gsm also interoperates with. can anyone test: cingular, sprint, verizon?

    if voicestream can send to all 3 of those in addition to at&t, that'd be totally fantastic.

    I sucessfully sent and received a message to a Europolitan customer in Sweden. Was quite shocked it worked.

    SMS should work to any GSM phone as long as the providers have a roaming contract.....

    Do files get embarrassed when they get unzipped?

    This part I knew, but I was shocked that it sent successfully to a normal at&t phone (tdma?). The jury's still out for us USA folks on whether voicestream also sends/receives successfully to non-gsm cingular, sprint, and verizon phones (as cingular is only gsm in, i think, the west coast and carolina areas)
