The iPhone may be one of the best smartphones on the market. But you are going to have a difficult time getting a whole lot out of it without a strong signal or WiFi. We have already covered external signal boosters you can use to get better call quality on your smartphone. These 2 booster cases enable you to make calls or access the Internet on your iPhone in a more reliable fashion:
Thuraya SatSleeve: this cool sleeve lets you make phone calls on your iPhone even if your signal is weak. It is a satellite adapter you can use to make calls over Thuraya’s satellite network. It serves as a backup battery for your phone too.
Linkase for iPhone 5: this case is fueled by EMW technology and boosts your WiFi signal by up to 50%. It protects your phone too.
You could always rely on traditional signal boosters to get more out of your phone. These types of add-ons can’t perform miracles but could improve the quality of your calls or internet connection.
