My online number from Mexico 55 84 21 94 is not working correctly in Mexico City. When my family use a landline from MX to call me another person answer the phone call, but if they use a cellphone it works and I receive the phone call. That's really weird 'cause when I suscribed to the services I read that people can call me using a landline or a cellphone. Could you help me with this situation? Do I need another online number?
