I know this is an old thread but what are the current best options for a local SIM card? I need coverage in Vitoria, Goiania, Cuiaba, Pantanal (if possible), Alta Floresta, Itatituba, Santarem and Belem-are there national carriers that have this?
Do they sell SIM cards at either GRU or GIG? I be transiting both places enroute to my final destinations. I don't need international calls, just want to be able to call hotels, guides, send local text messages.
