Phone cuts out after 30 minutes

[TC-MCSP1]

Hi, 

I have my new phone, Sony Xperia 10, the problem i have is that during a call that i make, the phone cuts out after 30 minutes. This has happened 3 or 4 times now. Can anyone help me solve what to do to stop this happening. I've read on other forums about deleting apps, but what ones do i delete.

Thanks in advance

Sadly time marches on and we are forced to 'keep up'. If you want functions (and apps), it's a smart phone and if it's a smartphone it's almost certainly touch screen. 

May the force be with you.
