We got my mom an international plan for a trip. In her iphone settings her Cellular Data is turned "on", and Enable LTE set for "Voice & Data". Should the roaming be set only for Voice Only, or also have the Data Roaming on? The International CDMA is "on". She doesn't want to accidentally get hit for extra roaming charges. Anything else we should know about? Thanks!
if the international plan you purchased offers data usage you ought to turn the data roaming on. if she wants a little more control maybe she could toggle the cellular data switch when it's not in use.
