Trouble dialing out from U.S. with United Mobile SIM

Przemolog,

Well, I tried it, but perhaps I did it incorrectly. Did you mean, enter "Star" - 137 - "Star", before entering the country code? I did that, but the same thing happened.

I've also tried dialing their "Easy Code" numbers, i.e., 094 for customer service, 089 for balance inquiry, etc., and that does not work either. I even tried searching for the different available carriers, i.e., Cingular, and T-Mobile, and registering with them to see if that was the problem. Since I can change registration with these, I assume the phones are able to receive, just not able to send a signal.

Sigh ----

Is should be followed by the hash sign #.

What I typed as: *137*CountryCodeNumber# you should understand in the following way (examples).

To call +1-234-555-6789 dial *137*12345556789#,
to call +44-7926-123456 *137*447926123456#.

The real thing behind the callback in UM+ and other international SIMs is a code of the above kind in which the destination number is "wrapped". Because using such codes is inconvenient, some smart people invented applications that "catch" numbers dialled from the keyboard or selected from the SIM/phone memory. Thanks to those solutions you should be able to make yor calls almost normally i.e. you dial the number as usual and the only difference you wait for the callback right after. The problem is that many phones on the market don't allow such "catching". To bypass it, dialing menus are added. n cases they fail too, and dialling with using the explict "wrpaping" code is the only way that works....

http://www.telestial.com/ is selling a new Siemens European dual band and a sim with $20 calling time on it for $49. The sim is not the world's best in terms of calling rates, but I'm pretty sure United Mobile works well with Siemens phones.
