(Thanks to NoCamels.com) Israeli start-up Glove has an app that analyses which network provider gives you the best reception for your mobile phone. You run the app for three days and then it puts you in touch with the ideal carrier. It’s useful for anyone buying a new phone or moving to a new area.
