Why am I getting txt like saying my phones about to shut down prolific spam and how can I stop it

Hi Karenjen,

It sounds like you're having an issue with spam messages on your iPhone. If so, for help with reporting spam messages, check out the steps below found in the article here: Block, filter, and report messages on iPhone

"Report spam or junk messages

When you use iMessage, you can report spam messages to Apple. Depending on your carrier and country or region, you can also report spam you receive with SMS and MMS.

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.

Note: Reporting junk or spam doesn’t prevent the sender from sending messages, but you can block the number to stop receiving them.

If you don’t see the option to report spam or junk messages you receive with SMS or MMS, contact your carrier. See the Apple Support article Wireless carrier support and features for iPhone."

You can also find helpful information here: Block phone numbers, contacts, and emails on your iPhone or iPad

If you feel the issue isn't spam text messages and something else, check out article here: About Lockdown Mode

Hope the information helps.

Cheers.
