I am writing software for a researcher in *South Africa* and would like to get advice on selecting an appropriate phone for the study. We are studying migration patterns of people with HIV and we need to supply them with *unlocked* phones and pay as you go plans. It is to cost-prohibitive to give them a 1 or 2 year cell phone contract.
The phone must support the following:
2) push notification
3) internet connectivity for website updates
We have been looking at the Nokia 5230, it's about $200 US dollars.
So my questions are the following. Does this phone look like a good candidate for the study? Are there any problems that we might face with this phone? And lastly, is there another phone that you might recommend that might be less expensive while still being able to handle our requirements?
