Our experience is that once you make contact with any of these insurance companies you will be bombarded incessantly with phone calls, WhatsApp’s, and emails. Then, once you do decide to go with one of them and sign up, the sales executives will drop you like a hot potato with the documentation half complete so that they can move onto the next victim. Exactly this happened to us with Prevención Salud (Sancor) and OSDE. Prevención Salud was totally useless, not accepted by any pharmacies close to us, their “call a doctor” application never connected to a doctor, and when we decided to stop using them they refused to accept our termination request. We’re now with OSDE, it’s somewhat better in that it’s at least accepted by the clinic and pharmacies we used. One thing that works perfectly with these companies is their billing, expect to be charged and overcharged while they sort out the details of your monthly quota. If anyone in your family will work on an Argentinian contract, a deduction is automatically made for health insurance (obra social”) and it’s possible to direct these payments to the insurance of your choice, leaving you in theory to pay only a top up for the policy. This requires a notarised declaration, which OSDE can do at some of its offices, but they can take over 6 months to process it and in the meantime they will charge you the full amount. Be aware also that once you go this route you’re locked into the insurance for a year (the sales people won’t tell you this of course).
