I put the SIM card in and apparently I have service--I attempted to make a phone call just to check and received a text from ekit saying to stop and put in the UK pin code for cheaper calls.  I did not receive a text with a US number in it, however.  I don't NEED a US number, but I wondered if that means there was some problem with the setup--or since it powered up and I was able to receive a text from ekit, does that tell me I'm fine, the phone is unlocked, and I'll be ready to go once I reach the UK?  Thanks again.

Thanks so much for your response.  I feel safe to check it now.
