I will be traveling to Zambia for 2 weeks. I plan to purchase a travel plan but want to limit my data usage while away. I will be using my S10 for photos and emergency calls only. I will turn on wifi when available but it will be limited and slow. Plan to use airplane mode most of the time.
What settings can I use to stop app updates, notifications, text msgs and other unnecessary activities while traveling.
What settings or apps are necessary to make calls over wifi?
