U know that if you call any no for 1mut in etisalat they will give you xtra 1mut. Ok just use your etisalat no to call your mtn no,after that peak it and when it read reach 7second cut it, so dont tuch your etisalat cus it will continue riding so you just no tuch it till it cut by itself.if it reach 1hrs b4 cut that simply means you will have 58 minute free calls to any network, it sound graet try it.
