The cell phone company Mobal "www.mobal.com" which does not charge for the usage of the SIM if you do not use there SIM to make a call but it remains active for calls. mobal has charged me for calling there customer service number +1 212 785 5800 which is free. I am located in Canada and received a united Kingdom number (I do not know why). Is there anyone else using this service? I will not allow them to get away with these charges.
