The cellular switch on the iPhone is defined within the carrier settings. This is how the iPhone works so despite what your carrier is telling you they had a hand in this. If you try to roll your phone back to iOS 7.1.2 you will also need to obtain the old carrier settings profile. Or you will have to switch to Android or Windows.
It is iOS and the type of iPhone that define how celluar network is configured, i.e., whether you can use 2g, 3g or 4g. The carrier has nothing to with the phone's settings.
If you have iPhone 4s with iOS 8, you have the option to toggle of 3g, but this is not the case with iPhone 5 and iPhone 6. I have recently bought iPhone 6, and I have no option to toggle of 3g; there is only option to use either 3g or 4g, but cannot choose 2g (edge), but with my iPhone 4s I can toggle of 3g. If it is the carrier that determines celluar network, why Android phones have the option to use both 2g, 3g and 4g within the same carrier netwok?
I do not have experience with iPhone 5s, but I believe that within the same carrier network, iPhone 5 with iOS 7 can toggle of 3g, while iPhone 5 with iOS 8.0.2 cannot. From this, it is obvious it is operative system and not carrier that deremines how celluar network is configured.
The problem with iPhone 6 using iOS 8.0.2 is that the phone is constantly looking for 3g network, even if I disable celluar. It does not look for 2g, but by default, looking for 3g. The signal is very weak because 3g is weaker than 2g in the area I live. On the other hand, iPhone 4s has strong signal, because it can use 2g, ignoring 3g.
I believe that it is iOS causing such behaviour. I hope that with the next update of iOS 8, this will be solved.
