Reset network settings, replaced the antenna as well as the flex cable. It seems to work only for a short time – when I reseat the SIM card and reset the network settings. It then goes to SEARCHING… then NO SERVICE and then back to the provider network.
I did review other similar questions.
Could it be the SIM card or connectors in that area?
Es esta una buena pregunta?

These symptoms usually lead into a rabbit hole. While it is searching/No service, input *#06# into the keypad and see if it brings up your IMEI number. If it doesn’t you have baseband problems. The other thing you can check is the bottom antenna it is located beside the charge port connector or is that the one you already replaced?

When the No Service or Searching... is indicated I cannot bring up the IMEI number. Very disappointing news, but thanks for the insight.
Currently, it does work, but it will start searching soon. :(
Could I use my heat gun to soften the solder on the baseband chip, then let it cool –in hopes to establish a better connection? Or is a full reball and jumper the only answer?
@suttonimpact You could try. I have uploaded a pic to show you where to put the heat. You will need to remove the bottom shield. To permanently fix this you would need to remove the baseband CPU and run a micro jumper wire from the U1 pad to a test point which is on the other side of the board than re-ball the baseband CPU.

I've seen that problem before. even if you replace the correct part. usually it will work temporarily but after a while the problem will come back.
I speak from experience that this is not easy or impossible to make

Yes, it looks like it. I gave the phone to my son (it still has great wifi) just no cell service. Bought the XR begrudgingly!

When did this start happening?

How many bars are you seeing in the top corner?
Was the phone working before at the location you at presently?

I dropped the phone...all seemed well except the Wifi. So I replaced both the antenna and flex cable. I saw the old flex cable foam had been dislodged. I hoped the new cable would do the trick.
