When i text someone, the majority of the time it wont send,
but it has the icon beside it the ))) icon, but i have to switch
it off, & back on before my it will send. & my messages are
delayed.. i have to switch it off & back on, sometimes even
pull out the battery because i dont know when i have a message,
& then it comes through, & sometimes messages are delayed
24 hours, & come in all at once.

Also calls- when someone ring me they say it goes straight to
my voicemail, however my phone is on all the time. Any help
on how to keep my on time, so i dont have to keep turning off
& on my bold.

Who is your wireless provider, and what does the signal meter on the top of your screen indicate when you are having a problem?

OFF, SOS, GSM, gprs, GPRS, edge, EDGE, 3G, 3Gbb ?

it says 02-uk, & gprs, or GSM & sometimes 3G, depending on where i am.
it only says SOS when i have no signal.

I'm willing to bet that it says SOS or OFF when you're having trouble.
Keep an eye on it.

I would say you're in a poor O2 signal area.
