I hope this issue has been resolved. If not then I recommend to chat with customer service so they can take a look at settings etc.
Have a great week
I love my 570 but I am having a similar problem and this is the 2nd phone. the first time I assumed the problem was with the phone. Now I'm not so sure. When I send or recieve texts, the sent texts don't arrive or often arrive a day later. I don't consistently recieve texts. When I dial out, there is a delay in connecting to the dial tone. I have tried to update the software but the message says I have the most recent which is from June 2010
The last phone, this started happening and slowly progressed to randomly dropping calls particularly when I am not in my immediate home town. Not a good thing when one is travelling.
I took it to 2 repair shops and they thought it was something with the antenna. Again, that was the first phone but now I'm thinking it is either a flaw in the design or there is something else going on.
