Landline number unblocking itself on iPhone

There is a phone number that appears to be a landline that has been calling my phone twice a day for the past 2 weeks. I have determined that it is spam; therefore, I blocked it 3 days ago. This morning, I received another phone call from this same number, and it shows as "unblocked." What is causing this number to unblock itself?

Phone numbers can be "spoofed", that is, the purported number is actually a fake. Such numbers may appear to be the same when received on your phone but may in fact be different to the system and hence may get past any blocks.


Your best option may be to turn on "Silence Unknown Callers" in Settings -> Apps -> Phone so that these spam calls don't ring on your phone, though they get routed to voicemail so you may still get spam recordings. Then just make sure that anyone whose call you want to receive immediately is in your Contacts. You can also contact your cell carrier about the issue, though there may be nothing they can do.


Regards.

While smartphones themselves can't harbor malicious intent, we must actively fortify their defenses. Tighten your device settings, be mindful of how you sync, and protect your digital treasure trove by safeguarding sensitive information with your loved ones. Don't underestimate the power of simple security measures. Employ strong passwords, enable two-factor authentication, and regularly update software.


 However, the vulnerabilities lie in our usage and connectivity. Unsecured settings, careless syncing, and oversharing sensitive information can transform this innocuous device into a Trojan horse for attackers. Vigilance is key.


If you feel an unauthorized person/app is remotely using, controlling or monitoring your device, then that is possible only if you have done one or more of the following Don'ts...


  1. Don't hand over an iPhone to kids or to a stranger without Enabling Guided Access
  2. Don't share Apple IDs
  3. Don't Jailbreak
  4. Don't share sensitive information pertaining to your device
  5. Don't give in to Phishing
  6. Don't plug in your device in Airports and Public places through third-party cables and trust the device. Beware of Juice Jacking. (Especially in India)
  7. Don't leave your iPhone unlocked and unattended in public places like offices, schools, malls, etc.


If one of the above is true then quickly change the Apple ID Password and Return iPhone settings to their defaults.
