On which website or software can I send unlimited short messages to my mobile phone, and it is free?

Nothing for nothing. It is a pleasure to watch others use some so-called free SMS software. I really can't stand it. Are all these businesses * * * manufacturers? Out of conscience, I stand up and talk about the shady things that you may not understand:

All software that provides free SMS can be divided into two categories:

1) If you want to register with your mobile phone number, you can send short messages for free after registration.

2) If you don't need to register with your mobile phone number, you can send short messages directly for free.

I'll tell you where they are black!

Let's talk about the first category, which requires mobile phone number registration.

For example, QQ, POPO, message kangaroo, UC and so on. You need to send text messages for free. Of course, you need to register a mobile phone number, usually fill in your mobile phone number, and then their system will return you a verification code. If you fill in this verification code, then you can start the service. Free SMS is allowed, because your registration means that your mobile phone number has been recorded by them for future use. What is it used for?

Think about it, sending a text message costs 10 cents. As an SP (that is, a wireless service provider, that is, a merchant who often sends messy advertising messages to everyone's mobile phones), there is an agreement with China Mobile Unicom. If it is sent through their port number, it will be counted as 5 cents, and if there is a reply, it will be offset. But there must be a cost. There are so many chat users that they can send short messages through its port number for free. Are all these businesses * * * manufacturers? Of course not! Their official excuse for this is that we get more users through these means, thus providing support for our advertising business. This excuse is very pale! Wireless advertising is not easy to do now!

They have a brilliant idea! They said, "Sign up for UC/QQ/POP now". How many messages do they send for free every month? Note: What does the word "now" mean? It means that there is no charge only during this period! When will it be collected? Sorry, SP won't take the initiative to tell you, and then after a while, about half a year later, he began to collect monthly rent without informing the user (this move is the history of kangaroos). Users wait until the money is deducted before complaining. Their statement is: free for half a year, and now the time has passed. They charged and made a notice, but you didn't receive it. The most you can do is apologize. Think about it, as an SP, from a certain month, you suddenly charged millions of users a few dollars a month for rent. What's the total income? ! ......

Besides, you sent a text message, and you and your friend were in trouble. Because you send a message to your friend for free, and that number is also recorded by SP, as long as your friend replies to your message, even if you use SP's service, it is "reasonable" to collect money in the future charging month. Even your texting friends are in trouble because of you! ! !

Category II: No registration required. Speaking of which, do you understand where the black is? By the way, if you don't register, you will be spared. The money of the mobile phone will not be deducted, but you will be sent to your friends as an accomplice, and their friends will reply and deduct the money!

Everyone has to ask again: why do you need a friend's reply to deduct his money? Because the SMS platforms of China Mobile and China Unicom are based on MISC, merchants can't deduct users' money casually. Only when the user sends a message to the port number of the SP actively can it be regarded as a service registered with the SP, and the fee can be deducted. So if you send a text message to QQ/UC to register the verification code, it is equivalent to sending an uplink (called uplink in the industry), and then your friend replies to the message you sent him, and the other uplink is sent to SP by a friend. Then after a few months, SP deducted your money, which was justified. You can't sue him if you complain!
