Hi everyone
I have been following this discussion since day one.
I purchased the iPhone 7, on 3 since the day of release.
Have had problems on and off. No proper fixes I can see yet.
3 mobile now have given me £6 off my monthly bill for the rest of my contract with them.
Disappointed with Apple.
I think this comes down to the Intel chip and it not being configured properly with 3.
This article pretty much sums up the issues with it.

If you do not have time to read it all, I have pasted the conclusion below.
Conclusion
After testing, the conclusion is that the iPhone 7 hardware with the Qualcomm-powered modem has a significant cellular modem performance edge over the Intel variant.
As to why Apple has sourced two baseband suppliers after years of using Qualcomm hardware exclusively, it likely has much to do with broadening its supply chain. In this case, however, it looks like supply chain diversification has resulted in a measurable performance difference between the two models in a lab-controlled environment.
Of course, controlled tests differ from real world usage and scenarios, but these findings are nonetheless interesting. I tend not to read too much into this data, because Apple has no-doubt tested both models, and found that each performed satisfactorily in real world usage.
Also worth noting is that the iPhone 7 with the Qualcomm modem is only being sold in China, Japan and in the United States, which means that Apple deemed the Intel version to be good enough for every other territory.
That said, if you’re buying an iPhone 7 for full price in one of the aforementioned territories, then I highly recommend going with the Verizon/Sprint/SIM-free version. Not only does this version seem to perform better from a cellular modem perspective, but it’s also capable of working with most cellular carriers in the US and abroad.
I hope IOS11 will fix this in someway?
