I’ve never owned a smart phone, but I use a flip phone. Many flip phones sold in the United States have Internet, 3G/CDMA/UMTS, and even 4G/LTE capability. But a more basic flip phone will be just that, just for calls, texts, but it will be 3G as 2G frequencies are no longer in use.
In fact, if you live in the United States, China or Japan, flip phones are more popular there and there is a wider choice. In Europe the choice is more limited, and most European flip phones with UK specifications are GSM 2G/EDGE and WAP for basic internet.
How is it? I’m not glued to it all day, or checking it every 5 minutes. Battery lasts about 2 weeks, costs £39.95 ($80) in 2013, costs £1 ($2) per week for 25 minutes, 50 texts and 10MB per week, with free loyalty bonuses every 3 months , where you can add more minutes, texts or mb for free.
