I walked over to Belize Telemedia Limited to set up phone service so that we could get internet at the house we are renting. Everything was going great until the girl asked for ID and she found out that I didn't have a Belizean social security number. She had to check with her supervisor to find out how to complete my transaction.
It turns out that the cost of being a foreigner is a $250USD deposit. The supervisor told me that the deposit would be refundable after 24 months of service if a good credit record is maintained. So $334USD later I was able to walk out of there with a new modem and installation scheduled for Friday.
I guess buying a washing machine will have to wait another month!
