This can be from the sale of personal data by companies who you've given your number; it can be from data leaks; and also can just come from spammers randomly generating numbers. It goes without saying that you should never tap on any links in suspect messages or provide any data those messages request.
In the list of messages, touch and hold the spam message, then tap Report Junk. Or, if you've opened the message, scroll to the bottom of the message, tap Report Junk, then tap Delete and Report Junk. The sender's information and the message are sent to Apple, and the message is permanently deleted from your device.
If you receive any unwanted email, the best approach in almost every case is to delete it immediately. It is often clear from the Subject line that a message is junk, so you may not even need to open the message to read it.
Why am I getting spam text messages? Spam texts are both intrusive and pose a security threat. If you are getting spam texts, it's more than likely that whoever is sending you a spam text message is trying to get access to your personal information—bank accounts, passwords, social security number, online IDs and more.
If the spam keeps rolling in, it could mean your email address was exposed in a data breach. It can be hard to prevent spam when cybercriminals have your information. One option in this case is to change your email address. Start by registering for a new account with your current email service.
How to block spam texts on Android. On an Android, go to the three-dot icon in the upper right corner and choose Settings. Tap on "Block numbers." You will find several options, including unknown callers, recent call, or from your contact list. Choose or manually enter a number you wish to block.

If you reply, you'll start to receive more spam and scam texts and calls. Call a number listed in the text and disclose your personal information. Some spam texts include a phone number to call to stop a fake payment or deal with a made-up issue.
Don't “click” open links in unsolicited text messages. Clicking the link may infect your mobile device with a virus or malware designed to steal the personal or financial information stored on the device.
“A good general rule of thumb for a text from someone you don't know is to just ignore it or delete it,” says Stephen Cobb, senior security researcher at ESET, a company that makes antivirus and Internet security software for businesses and individuals worldwide.

Automatic deletion of emails
Once an email is deleted from the Trash or Spam folder, it cannot be recovered in the mailbox.
It's very difficult to stop spam, mainly because it's often almost impossible to trace its origin. But this doesn't mean that it's an impossible task. In general, a good anti-spam software is enough to block most unwanted messages.
When you block a phone number or contact, they can still leave a voicemail, but you won't get a notification. Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked.
The next major impact of blocking a number is on SMS messages. When you block a number on Android or iPhone, that number cannot send you a regular text message (SMS or MMS). Even though the message will be sent from the sender's side but you won't receive the message. Messages, like calls, have a one-way impact.
When you disable SMS, the iMessage system automatically takes over, and sends and receives messages using your cellular or Wi-Fi data connection. To ensure you don't receive any text messages through SMS, you can also disable your cellular data connection to force your iPhone to use an available Wi-Fi network.
Which is better for you? Most iPhone users will want to use iMessages, so long as they have a good plan that can handle the data usage. The only reason to use SMS instead of iMessage is if you're chatting with people who don't have Apple devices, or if you don't have any data on your phone.
