Calls drop out exactly after five minutes in several different locations

Hello,

Call drops out exactly after five minutes in several different locations. Always with the same number which  happens to be my wife's !! Incoming or out going calls and it drops bang on five minutes she jokes  all the times that she will be getting cut off soon as it's almost five minutes. The signal always looks good also happens when I'm abroad 

Any help appreciated

More a long shot than anything, but try with & without caller-ID present.

If it happens abroad, that rules out a radio network issue. If you're able to try a 2way SIM-swap between your phone and your wife's phone, that would prove it to a phone or SIM/account issue.

Your SIM in your wife's phone - what result?

Mine did this for about a month or 2 and now it is ok. Weird.
