But she could use her data to access the Skype app and make phone calls that way.Regarding cell phone service....her family noted in the update that she had an Esim. My understanding is that an esim is a sim card that only provides data; not cell service. (I might be misunderstanding what and esim is, so feel free to correct me if I'm wrong!) She would have to rely on Wi-fi. This would explain why she said she might be out of range for a while as she wouldn't have access to wifi on the trail and some places might have limited, or no, wifi. Having said that, the Mandokoro guesthouse indicates in their listing that they have wifi.
That's what I do when I'm overseas and have a data-only SIM from that country.
