Dear all,
We have some customers complain that they got many missed calls (call logs) but they havent seen any imcoming calls. The caller said that they hear no ringback tone then got ann 'subs is unavailable' after 10-20s.
The called number is most of time in 3G, when we check the signal strength is quite ok (RCSP ~75dBm).
Sub used iPhone 5.
My quesrion is why they got missed call (in call logs) but called number got 'unavailable'? Is it handset problem? Anyone using iPhone 5 get same?
Hopeful got your advise.
