-It seems that UM does not exist anymore
I check my account today it says
0 (It should be 9 Euros), in the status of the card it says "(Unknown)"
and if you try to log on any network it's impossible
Then this discussion is closed
GT SIM is better than UM because UM does not exist 
anymore
For now i still using GT SIM they still have a not to bad (not to good too) service and a reasonable prices and no problems
Just this, do not forget that
Global Sim company are not really stable and hope that nobody loose to much money
Hope also that they will come back because they service was not bad.
