Options are many for ET phone home:
- Buy a prepaid card that you can use at any phone (payphone or residential), not as expensive as a regular call, you dial an 01-800 number, input the looong code in the back of the card and then get switched to the USA and dial as usual.
- Go to an internet cafe and call via VOIP with a computer, maybe using SKYPE or something similar. If you don't have a Skype account use the cafe's voice service.
- Buy a simcard for your cellphone and some credit. Not the cheapest way.
