Last trip I turned off “cellular data”. Kept my phone on so incoming calls and texts could come in. I just waited to be on WiFi to respond if it wasn’t important. Was down for 6 days and I had zero extra charges. I could have triggered the 10 a day and use data but didn’t need to. And Global roaming was on, but as long as I didn’t dial or text there is no charge. It’s taken forever for me to figure it out!!!!
