softbank 007SH calling and msging issues

[masamune date]

recently i hav brought a 2nd hand 007SH soft bank phone, in good working condition, however my M1 sim card was too old so it can't be used, the solution was to change the sim card to a new one, so i change it and the sim card was the latest sim card with the ID 1-V11

however, even after changing the sim card etc, the phone's basic functions can't be used after 5 mins, the signal bar is full with 3G, the 1st few mins of using the phone work well, i can call and msg, but after around 5 mins i can't seem to do anything, when i call it will hang at the dailing screen, and when i call using other phone numbers it will still get thru, jus that i can't recieve any call on my 007SH, the only thing that works is 3G so internet and whasapp are avalable, another funny thing is even if the signal is low, it will still show full bar

the best thing is i tried using my bro's sim card which is older a little, and the basic function works, it can call and msg even after 5 mins, the difference between me and my bro's sim cards is ; my bro's old sim card has a bigger gold plate with a diff ID, while my sim card has a smaller gold plate with a diff ID 1-V11

so any solutions to this?
