How do one call overseas with ZYM mobile plan? Do I Need registration for Roaming? Any budget call code like 019 / 018

Worst provider, doesn't have the courtesy to prompt overdue payment before suspended the line.bern using circle life for 5 years with no issue even slightly expensive but will no suspend line just for few days overdue.will change back to circle life.sorry zym,guess you are the worst network provider,just overdue for 1 week and the amount was just 70.u suspended without giving any sms.will not think twice to go back to circle life.just doesn't want to have further panic.
