Hi. Nagregister ako ng Gosurf50 tapos nung naubos yung data at 2 days pa before expiration, nagregister ako ng homesurf15 using globeathome app. But lumalabas lang si "message sending error". daming threads na ganito at walang helpful suggestions at solutions manlang, is your service substandard? What is the problem and what is the solution to this problem?
