Since almost everyone has a cell phone with a caller ID built right into the system, your number shows up when you call. That probably fine in most cases. There are ways to block your number from showing up when you call if you need this function.
The first solution is temporary and simply requires that you dial *67 before making a call. Punch in those digits before any others and, assuming whomever you're calling isn't an emergency service of some sort, your number won't show.
For a more permanent solution, give your provider a call and ask how much a line block would cost to add to your line. Typically, it'll be something like $5 per month. This will prevent your number from showing up any time you call -- except for emergency services, who hopefully won't be screening your calls anyway.
Other phones have Caller ID block settings that can easily be switched on or off by going into the "Settings" menus.

Most Smartphone Users Don't Install Security Software
4 March, 2008 By Chris Talbot
Most mobile phone users don't have security software installed, even though three-quarters of them are aware that malware can infect mobile devices via Bluetooth, according to the "Online Wellbeing" survey commissioned by security-as-a-service provider F-Secure.
The report was based on surveys of Web users aged 20 to 40 in the U.S., Canada, the U.K., France and Germany. In the survey, they were asked about their knowledge of online and mobile security issues. Of the respondents, 28 per cent said they use their mobile devices to access the Internet, but 86 per cent admitted to having no mobile security in place. However, most users said they were aware of the security risks involved in using the connectivity features of their phone. Only 21 per cent of respondents said they regard Bluetooth connections as safe, and only 15 per cent said they thought Wi-Fi connections were safe.
Additionally, more than half of the respondents said they felt it was up to the individual user to ensure their phones were protected. About one-third said they expect security to be dealt with by their mobile phone carriers (the U.S. put even greater emphasis on the third-party responsibility).
"While the mobile threat is low at present, it's only a matter of time before Internet criminals start utilizing the growing potential that smartphone usage presents to them," said Mikko Hypponen, chief research officer at F-Secure, in a statement. "So far there have been about 400 mobile viruses detected, but as smartphones replace PCs as the dominant Internet platform, we can expect this figure to rise."
F-Secure stated that the low number of people with security software installed on their smartphones combined with the rapidly increasing number of these devices on the market makes them very vulnerable to hackers.
The vast majority of cell phones and PDAs contain personal and proprietary information. Some users password protect their devices and some don't.
Going back to the days of my first cell phone, I did password protect it. It seemed like a good idea, but it was a pain every time I had to go through the drill. So, after the annoyance got to me, I got rid of the protection. Not smart.
YOU'VE ERASED IT AND IT'S GONE...RIGHT?
The hard drive on your computer, be it a Mac or PC is just like the one on your cell phone or PDA. When dealing with your unwanted files and info, you delete the data and it's gone. Right? Well, maybe not.
At some point, you might want and/or need a new device. What to do with the old one so as to not add to the toxic mess in the landfills.
Suggestions...donate it to the police for senior citizen use, give the old phone to your child, or significant other.
FAST TRACK YOUR PRIVACY...OR DEAL WITH POTENTIAL PROBLEMS
The operative words are, OR ELSE. You've heard about gone, but not forgotten. Try, gone, but salvageable. Probably not what you wanted to hear unless you really need that file. Bottom line...salvaging data from discarded devices is a slam dunk with the right tech guru on a mission.
In fact, for those of a curious nature, (perhaps even that bright little one of yours who takes after mommy or daddy) there are even free Internet tools along with commercial tools to resurrect date. And, we're looking at a very small tool with minimal code.
When you delete a file, all you're doing is changing the index of the file or the file pointers. Since phone and PDA data is stored in flash memory, it's still there even if the battery is removed or drained. The only way to delete it is to use a "hard reset" so that it reverts to the original factory settings. By the way, this is not something that you can do yourself since each manufacturer has a different procedure.
Given the fact that private chat logs (really messy in case of a divorce, or sensitive business dealings), business e-mails, marketing plans, credit card numbers, and passwords should not be easily accessible, password protect. I don't recommend placing credit card info into any of these devices and you may not agree. How hard is it to take the cards from your wallet or purse and use the info?
How much of what you place in memory do you really need? One last comforting thought, 90 percent of discarded cell phones and PDAs contain sensitive material.
