Apple Watch interfering with 6plus connecting to microcell?

HI,

Has anyone ever had an issue with your Apple Watch (os up to date) interfering with your iPhone 6 Plus (also up to date software) being able to connect to your microcell signal booster?

Around 2 weeks ago is when I started having this issue. I at first thought it had nothing to do with the watch, as I reset my phone, and then everything came back and it connected to the microcell fine. But, I forgot to pair my watch back up to the phone. I repaired it the other day and within a few hours it wouldn't connect to the Microcell signal booster anymore. I cycled the watch to airplane mode, and did the same to the phone, and it worked for a little while, but now it's disconnected again. And It won't reconnnect to the microcell at all now. I've also reset network settings ever, with no Change. Ive reset and disconnected the microcell as well.

As of a few minutes ago, I unpaired the Apple Watch from the iPhone, and it still won't connect...So now I'm completely stumped. My finances phone connects just fine to the microcell, but he doesn't have an Apple Watch. I don't know why the Apple Watch would interfere with the phone being able to connect to the booster? It worked fine for months, and then all of a sudden this happened. I have zero service from AT&T where I live, and the iPhone is the only phone we have... I don't know if it's an issue with my phone? But I have no idea what else to do.😕

Any ideas?

Thank you!
