This probably goes out to the people in here that know alot about the GSM/UMTS network and its capabilites. A thought just crossed my mind when i thought about what my ex-girlfriend told me some time ago. She said that her Kazakhstani cellphone operator "K-Mobile" has to have an agreement with the operator that she is sending SMS'es to. In my wildest imagination i cant believe that this would be correct. Can it possibly? I mean what kind of service would that be if you cant send SMS'es to whoever you want because the recepient might not have a contract with an operator that your own operator has an agreement with. It sounds strange, in my eyes you shouls be able to send SMS'es to whomever that has a cellphone number, anywhere in the world. Have i lived under a rock all the mobile era?
My own worries are directed at the fact if it is possible for me to communicate unrestrictedly with my "3" contract, i am worried that people that have my number might not be able to reach it by SMS because their operator might not have this agreement with my operator.
Thankful for any input.
