Everyone must be clear about one thing. At present, the three major operators have not launched data cards with 0 monthly rents. The regular number cards have monthly rents, and the fees are deducted on time every month.
The so-called 0-month rent traffic cards on the Internet are actually "IoT cards", also known as "pure traffic cards".
When it comes to the IOT card, apart from the 0-month rent, there is another obvious feature, that is, it has a single function. Without a mobile phone number, you cannot register, you cannot make and receive calls, and you cannot send and receive text messages. You can only surf the Internet. Networking cards are not allowed to be used on mobile phones, so it is not recommended to buy them.
The tariff of this package is very cheap, but you will find that this card has many shortcomings in the process of using it. Let me explain to you one by one:
1. Serious traffic false mark: I bought a 100G traffic card, but actually used up less than half of it. Most of the small quantities will be about 20%-30% inflated, and unscrupulous merchants inflated by 50%-70% are also relatively common.
2. The network speed is extremely unstable: In addition to the base station, the unstable network is also related to the incompatibility of the mobile phone model. This is the case with the IoT card. The IoT card is widely used in smart terminals such as shared bicycles and smart vending machines. On the device, according to national regulations, IoT cards are prohibited from being used on mobile phones and tablet devices, so many mobile phones need to reset the VPN when using IoT cards.
3. Card lock and card blocking: The three major operators clearly prohibit the use of IoT cards on mobile phones, so the operators stipulate that they will not sell personal devices. If the operators are found out, it will easily cause IoT card locks And block, even block cards in batches.
3. Unstable after-sales: The recharge interface is different for different IoT card merchants used on personal mobile phones. Therefore, if you cannot contact the merchant or provide a recharge interface, the IoT card cannot be used normally, that is, it will be scrapped up.
All the data cards that advertise "0 monthly rent" on the Internet are often false propaganda and word games. The editor recommends that you do not apply for this kind of card. In a word, the IoT card looks very fragrant. But after using it, the taste will change. Everyone should choose carefully. It is best to choose an ordinary mobile phone card, and don't be greedy for small things.
