Recently I posted about Google Android secret codes. After that mobile phone, I got my hands on the new stylish and awesome phone "Samsung Wave GT-S8500" which comes with Samsung's new Bada OS.
While playing with the new phone, I found some interesting hidden secret codes which can enable/disable various hidden options and can also provide lots of useful information about the phone which is not available in default menus.

Dear sir / madam
In June this year I have been to spain , Barcelona and I went to the Corte Ingles, where They sold me a Samsung Wave GT - S8500, but they sold me , the telephoneon and I put the chip of mexico. . The thing is that i live in mexcio and the vendor did not tell me that the telephone won't work , as I unfortunately found when I came back to Mexico.
I wrote them to know if is something wrong is with my telephone and they swear me that i can use it , but I can not send for example MMs or use the applications that cames with the phone.
I feel cheated and fustrated , because I think this telephone is marvelous. The question is , what do I do now ?.
I heard that it can be unblocked , but the Corte ingles says that there is not need, that the telephone is unblocked.
Please, could you tell me if I have hope in using some day this telephone in Mexico, or I have to resign to only receive calls and to make calls only, and to miss the applications software of the telephone.
I do not want to ruin the telephone by dooing some in order to fix in it.
Please I would appreciate if you could advice in this matter.
Your sincerely
Laura Dunovits

^^ If you can send/receive calls, it means its unlocked and will work fine in your location. Regarding applications and MMS not working, it might be a incorrect setting problem. You should get the correct MMS settings from your service provider and put them in the phone.
