The information sent by the official number, there will be no problem with the links inside.

Can you believe the incoming call displayed as "official number"?

No matter the number displayed as 10086, the number displayed as a bank such as 95588, or even the number of relatives and friends, it may be fake. In the communication industry, there is a fraudulent device called pseudo base station, which is an illegal radio communication device, mainly composed of a host computer and a notebook computer. After the pseudo base station is started, it will interfere with and block the operator's signal in a certain range, and then search for nearby mobile phone numbers, and can use the official or other people's mobile phone numbers to send spam messages such as fraud and promotion to these users' mobile phones at will.

It is understood that pseudo base stations are often placed in cars, which are hidden and constantly moving, and it is difficult to be found. Some high-power pseudo base stations have a wide radiation range, which affects many users. Pseudo base station is an important source of spam messages and an important means of telecom fraud.

Can I click on the SMS link displayed as "official number" after receiving it?

Be careful when you receive any SMS link from the "official number", because if it is a SMS link from a pseudo base station, some may be infected with a virus, and it is too late to quit. Especially when you click on the link and find that the pop-up web page needs to fill in the bank account number and password, you should be more cautious at this time, because many businesses do not need to fill in the bank account number and password online. If you really want to go to the official business hall or the bank's website to handle business, it is recommended not to enter through the SMS link, but to enter official website directly.

In fact, although many fraudulent information sent by pseudo base stations looks "very official", there are still subtle differences in careful study, such as font size, thickness or punctuation. For another example, when doing business on a bank webpage, even if you want to enter a password, you will often pop up a keypad by protecting the password, or directly use an encrypted terminal device. Web pages linked by pseudo base stations are usually simple.

How to tell if the official number you received is true?

First of all, when you receive any promotional short messages containing web links and phone numbers, don't click on the links or call strange numbers. You can first call the customer service phone of the relevant company or confirm it through its customer service website.

Secondly, sending text messages from pseudo base stations generally blocks cell phone signals. Therefore, when you find that your cell phone signal suddenly disappears, you should pay special attention to the information you receive next, which is likely to be fraudulent information.

Finally, while strengthening security vigilance, mobile phone users should also learn to use mobile phone security software to identify fraudulent short messages sent by pseudo base stations through technical means.
