Questions please... I'd like to buy a tablet that isn't 5g ready as I don't wish to have 5g beamed directly at me. And I would like the tablet to have a magnetic sensor so I could download EMF detector apps. 1. Is it easy to determine if a tablet is 5g ready before purchase? 2. Are there any relatively inexpensive ($125 - $150) tablets that have magnetic sensors? 3. Will a tablet purchased in the US be able to access WiFi when traveling worldwide... for example, in Germany, Rome, Israel, Austria, NZ, etc? Thank you!
