iPhone 6 Plus Signal Dropping then Picks it Back Up

Check the top left of screen recording.

As you can see, I recieve 3 bars of LTE then one bar of absolutely nothing. I can’t send texts or calls or anything, unless I am on wifi.

I would like to add I have reset my network settings, turned off data and turned back on, and I have shut off my phone 10 times or more. I am also running latest IOS.

Is it my antenna or my carrier? I have had no problems until today.

Is this a good question?

Chosen Solution

After you have eliminated antennae, SIM card or network locks as the possible culprit, searching issues on the iPhone 6 series phones are usually related to the baseband IC. The baseband IC is very sensitive, just like the Touch IC's on the 6 Plus; it also suffers from poor quality traces and pads.

Go to your phone’s dialing keypad and dial *#06#. You should see the IMEI displayed.

If the IMEI is not displayed, the Baseband IC has to be reballed and two small copper traces (U1/V1) have to be rebuilt and solidified. This is commonly referred to as the “long jumper” solution. You can check out this answer (Service is "Searching" indefinitely) (by @teetopp) as it summarizes the issue really well.
