Worker can not fetch his wages.

[IMHO]

I take it that he does not have a bank account so that you can eft his pay?

Correct.

The cellphone route is a possibility. But what I am actually after, is how to enable him to send his 'wife' to come get his wages. BTW, he is illiterate and can not read or write, except for his name.

Is the cellphone route the only way?
