As I mentioned on in a earlier post once the core NEM is complete it maybe a good idea to look at using existing feature phones and SMS gateways. The use of M-Pesa in Kenya is an example of what can be done will relatively simple technology that already exists

Good technology appears simple to the end user... In reality what appears simple may not be...
This can be done, one approach is to design an integration to mobile money platforms and offer NEM as an add-on rather than an alternative...
This way you work with the Telco's not compete...
My humble opinion is you need something like a blockchain.info online wallet which can be accessed via SMS/USSD securely, a mobile money platform can hold the wallet-keys or a separate platform, I would think a telco agreeing to partner like this would run a NEM node along side its mobile money platform and take a stake.
There is also a lot of fraud around these systems (not technology) but spoof messaging which the Telco manages, people in these markets have very little money and if they don't trust you, they won't use you.
I know the concept of working with a telco (I am from one) will not sit well with some people but you won't get good enough security using these simpler protocols unless you can properly integrate with the network.
This is practically a good idea, but it seems hard to do. Why would a company like that want to work with us?
