IOS 11.2.1 "No service/searching"

After downloading IOS 11.2.1 yesterday my iphone continuously cycles between "No Service" and "Searching."

I've tried turning the phone off and on several times. I've also reset the network settings and ejected and reinserted the SIM card. Eventually my service comes back for a few hours only for it to drop again.

When I went to the verizon store I purchased my phone from I was told that they have had 50+ people come into the store today with the same problem and there was nothing they could do as it was a bug that has affected the antenna.

How can I get this fixed? Is there going to an additional update to fix this issue?

iPhone 7, iOS 11.2.1

To downgrade iOS11.2.1 to 11.2 only (as long as Apple is still officially signing the 11.2 version)...

On your pc or mac, go to iDownloadblog.com then select their Downloads tab, scroll down to the iPhone section & select the specific iOS 11.2. version for your specific iPhone model. Then select Go & download that specific .ipsw file to your pc or mac desktop.

Once downloaded, connect your iphone via usb cable & open your latest version of iTunes, then *fully backup* your iPhone first, then after it's done, while pressing & holding the Shift key on pc, select Restore tab in iTunes & pick the specific downloaded iOS11.2 version now saved on your desktop (if you don't press the shift key on the pc, iTunes will only download & restore the latest iOS version).

Once the Restore process is finished, your iPhone should then be on iOS11.2. Now set your phone up as a New phone first, then afterward, you can then restore data from your correct backup date. This process will work the same for any iOS downgrade as long as Apple is still allowing/signing that specific version (usually for only a few weeks after every iOS update).

FYI...I don't have Facebook or it's Messenger installed & still had the searching problem. See my earlier proposed solution to downgrade to iOS 11.2 if possible, per my earlier posts.
