My Blackberry 9300 intermittently cuts out the calls I make. Any call between 10 seconds and 2 minutes. This has been going on for 3 months.
When the calls cut out, you get that 3-note repeat call end tone. Yet the signal is strong; full bars. Also, the call quality is variable - sometimes incomprehensible - even with a good signal.
I've had the phone software reinstalled; the SIM replaced, (the new SIM works fine in my spare Nokia but the problem still exists when it goes back into the 9300); it's been to the repair centre 3 times and returned without them being able to replicate the fault on each visit.
Can anyone shed any light onto this frustrating problem!
Thanks in advance, Mark
