I want to get a Telepase for the road tolls, so I opted for the non credit card version which requires PIM, the virtual wallet for use with your mobile phone. I also understand that you can top up PIM with Mercadopago, which is another advantage, thus not needing a credit card.
It says dial *456# on your phone, then type in your DNI and you should be registered with PIM. The trouble is that it doesn't work work. It uses a data protocol called USSD - Unstructured Supplementary Service Data, sometimes referred to as "Quick Codes" or "Feature codes", is a communications protocol used by GSM cellular telephones to communicate with the mobile network operator's computers - which Claro is up tp speed on.
Anyway, I end up going around in circles, which is so typical of Argentine efforts to make life simpler. I even downloaded the app, even though the app isn't even advertised anywhere, not even on PIM's own website.
After investigating this, I discovered that the service has been dogged by problems, not least the waste of AR700 million on an app that doesn't even work and loads of people have their money locked up in the system.
Check out the comments on the PIM Arg Facebook page, which should be enough to steer well clear.
