To be fair, I have had ZERO issues with my Intel 11 Pro, and in fact, I've probably had BETTER performance with the 11 Pro vs. numerous Qualcomm iPhones I've owned over the years (Verizon user). I've owned almost every single iPhone since the iPhone 3G and on numerous Qualcomm models I ran into issues where I would occasionally have to toggle airplane mode after losing my data connection. This could have been poor iOS software programming just as easily as it was a problem with the Qualcomm modem or iPhone antenna design. But I've had this issue with both Verizon as well as AT&T over the years (former AT&T user in the early iPhone days) on numerous iPhones. The Intel XS was probably the worst and I had to toggle airplane mode often, but again, I've had no issues with the 11 Pro and its cellular connectivity after 1 month of ownership.
My point is, don't be so quick to blame the Intel modem. I'm not doubting that SOME people are having issues, but it's not a widespread issue for all users. You may have defective phones or might be using certain frequency bands in your area that are more prone to the issues you are experiencing, etc. Heck, carriers have different brands and models of equipment installed on their towers all over the country and there could be an incompatability issue there that is causing issues in some circumstances.
Regardless, for some of us, this iteration of the Intel modem is performing better vs. numerous Qualcomm modems in past years - at least with our carrier and in our cities. I hope that Apple gets to the bottom of the problems for those that ARE experiencing issues however.
