IPhone 6 kicks me off cellular network constantly?

My iPhone 6 is fully updated and I keep getting kicked off the cellular network. I will be in the middle of a call or looking something up (with full service) and will randomly get kicked off of the network. I tried resetting the phone to factory settings and rebooting but it still keeps happening… Has anyone had a similar problem? If so, how did you fix it?

You call your provider. It's not the phone.

It's most likely your carrier, not the phone.

  • Why doesn't my iPhone 3GS connect to the cellular data network? I just bought a refurbished iPhone 3GS from Gamestop a few weeks ago and have just started using it recently. I can make/ receive calls and texts with no problem, but for some reason my phone will not connect to the 3G network. I have 3G turned on and the symbol shows up in the top corner of my phone, as if it were working normally. I tried updating my phone, but there was no difference.
  • When you have Wi-Fi and cellular data on at the same time, does it use cellular data? If I keep my cellular data on and also have my iPhone connected to Wi-Fi, will it use any of my cellular data?
  • What's the difference between off-network and on-network? I'm try to work out which is best for what I want out of the service. I want protection while on my iPhone 5 (both when connected via Wi-Fi and when roaming on 3/4G). Website with product details: http://www.umbrella.com/products/umbrella-security-features/
  • IPhone 6 issue Could not activate cellular data network? I have a new iPhone 6, coming from an iPhone 4s. I have AT&T btw. In the top left it shows i have bars, and then the LTE or 4G symbol shows up, but when I try to use safari or anything web-based it says I'm not subscribed to a cellular data service, or "could not activate cellular data network". It works fine on Wi-Fi, but why won't it work on LTE or 4G.
