The user of a mobile phone faces a number of dangers: theft of the device, fraudulent activities, infection with viruses, etc. Each owner of such a device must have the knowledge and skills to protect against these dangers.
Instructions
Step 1
Remember that an outdated but multifunctional mobile phone is sometimes both more convenient and cheaper than the latest model, which has fewer functions. At the same time, the risk of its theft is much less, since almost all attackers are well aware of the range of phones and the years of release of various models. But when purchasing such a device, be careful not to run into a phone that is itself stolen.
Step 2
Carry your phone in a case. Through it, it is hard to see what model he is, and he looks less attractive.
Step 3
Never give your phone to anyone on the street. Even if it is returned to you later, it is not a fact that a large amount will not disappear from his account, or you will not subscribe to a service that involves periodic withdrawal of such an amount. If someone needs to call urgently, tell them that you will dial the number yourself and give the subscriber the required information yourself.
Step 4
Activate the service of barring calls and sending messages to the numbers of content providers with the operator. Set up your phone and all your family members appropriately.
Step 5
Beware of calls from scammers. They can pretend to be relatives in trouble - in this case, ask them a question to which they should be guaranteed to know the answer. If the caller claims that he has replenished your account by mistake, check if this is really so, or he himself sent a fake message about its replenishment. Do not dictate any USSD commands - they are designed to transfer funds to the attacker's account.
Step 6
If you use a smartphone, only download apps from trusted sources. Even a free program must be downloaded directly from the developer's site, and not from third-party resources. Phones with Symbian operating system version 9 allow the application to be installed only with a digital signature. But it will not hurt to install an antivirus on any smartphone, including those with such protection. Never install applications received from unknown sources via Bluetooth or MMS.
Step 7
If your machine only supports J2ME, always respond negatively to the Java Virtual Machine request for permission from the application to send an SMS message to this or that number.
