Hello,
I hike a lot and very often I find myself out of 3G/4G coverage. 2G is available, however. What I have found during these trips is that when only 2G is available, voice and SMS work, but there is no data. I do not mean that Internet service is slow, which is to be expected, but rather that there is no service at all.
For the record, I have an iPhone 7 on Drei, and, if it matters, roaming is active, including data roaming.
I also have an iPhone 6s using a foreign network operator....
I don't have any data on 2G
