Geez, all this phone talk makes me feel like I'm still in the dinosaur era. I still use my 'ancient' Hyundai mobile that i've had for donkeys years, first on a $10 a month plan & then on a $20 a month plan, when the initial plan came to an end. This is a phone that had dual compatibility with CDMA and next G, bought when CDMA was still operating. It is on it's second battery, which I bought a couple of years ago from a Bangkok street vendor. It works as a telephone & gets a better signal where we live than many more modern 'smartphones'. I recently learned how to send SMS messages with it - a bit of a pain with multiple pushes of buttons needed for each letter of the alphabet. It can take photos & video although quality is pretty crap & the screen tiny. It can even connect to the net on a limited basis, but I only tried it once when the phone was new. A couple of times people have sent me a photo & I believe I can send photos too, but have never learned how. All I want is a mobile PHONE, not a mobile mini computer, & this still does the job.
When the day arrives that we have to pay for our internet service** I guess it may be worth thinking about upgrading as part of a 'package' but until then I'll stick with my little Hyundai.

** Haven't paid for the 'net for the past 12 years +, we have an ISP microwave tower on our property for which they pay us a rental & include unlimited net usage.
