What about your husband's cellphone? Can he get an international plan from your carrier, or is it cheaper for him to buy a calling card to use? I'm sure you will want to be in touch with him.
Hubby has traveled in Asia, and he rents a cellphone at the Asian airport, to use while in the country. He's done this in Tokyo, Seoul and maybe in Taiwan. It makes things WAY cheaper.
Just remember to return that phone before flying back home.
I'm so sorry for your loss! That's so sad.
Is she from the country where she was living? Does she have family that lives there and is from that country? If so, they can help pave the way much more than making it all up. Does he know what religion she was, and what her wishes were?
If she's Asian, and especially if she's Buddhist, taking care of *her* can be less expensive since they tend to go towards cremation, but from our experience with FIL (who wasn't Asian but MIL is Korean, and he converted to Buddhism when he married her) the *memorial service* a few months later is the big money thing...
If this happened with us, we would just postpone celebrations. If you do the Santa thing, maybe have those gifts, but everything else just delay it.
If you don't have skype, but do have gmail, gchat with video is pretty decent, FWIW. A bit of a delay sometimes, which can be frustrating, but it's free and that's hard to dislike.
