My starhub postpaid phone cannot make outgoing calls or SMS whenever I am overseas. It says "'call barred" and SMS will always fail to send. Incoming call is ok. I have had this problem for years, but the help I tried to get previously insists that my autoroam is enabled and there is nothing wrong. I can't even send out an SMS to Starhub to activate roaming data. Please help because this is really dangerous if there's an emergency situation.
If you're still experiencing this even after restarting your handset, do provide me with your Registered Name, Registered Mobile Number and Hub ID/Email Address by clicking on this link> via Private Message and we'll keep in touch.
