iPhone overrides custom label for phone number.
I use gmail as my main contacts manager, and I have a multiple phone numbers (for multiple countries that I frequent).
I label each number according to which country their for (e.g My 3UK number is labeled "3UK", my AT&T is labeled "ATT USA").
The problem arises when the iPhone overrides these labels whenever the respective sim cards are used.
When I use my 3UK sim card, the 3UK label gets overridden and labelled as "mobile". Then whenever I swap sims in the US, the ATT label gets overridden.
I really don't need the iPhone to be relabelling numbers for me.
iPhone 5s, iOS 7.0.3
