So when i was at SJO, they couldn't sell me a SIM because the system was down.
I bought one at a corner store, but the guy there didn't know what the customer service number was nor did he have any information for configuring the APN
The APN settings are as follows:
Name: ice
APN: kolbi3g
MCC: 712
MNC: 01
For tech support call 1193 option 5, you can ask for someone who speaks English.
They will give you instructions for setting the APN for your phone.
general customer support is 1024
