In Safari and the Notes app on iPhone, wherever there are strings of numbers they get linked and treated as phone numbers.
I'm sure there was a setting to turn this off but I cannot find it. Where is it?
(Note: I'm not asking for how to prevent this happening on web pages as in this question, just a setting for my phone.)
Settings → Cellular Data → Cellular Data Options → Voice & Data → 2G.
Depending on your locale, Cellular Data may be called Mobile Data, as shown in the screenshots (UK). This feature is dependent on carrier support. If the feature does not exist for you, contact your carrier.
As of iOS 11, resetting settings will purge the current backup password (this is relatively new) https://support.apple.com/en-us/HT205220#help
Obligatory note: Be sure to do Reset All Settings, and NOT Reset All Contents and Settings, which wipes your device :)
I'm glad you already deleted the old backups, because there may be some bugs in doing this and then running an incremental backup.

It is currently not possible to disable the automatic linking for phone numbers, web addresses, and email addresses on iOS 7, and it never has been possible on previous iOS versions.
