I have also found talkatone with google voice to be clearer and more stable than the skype number. But skype still has its place and I use it too.

True all 4s are gsm and cdma compatible. What I meant to say is that if lynn's phone was originally locked to at@t regardless of whether or not it is still under contract I can get it unlocked. If it is any other carrier I cant help.

@big tuna. I cut my card down to size myself. Really easy. The apple stores here will also do it for free. As for data plans they vary according to what you need. As for calling the states I suggest you get a google voice number. It is free, convenient and has been very reliable for me. You can also use google voice to SMS for free as long as you have wifi or 3g. Look for talkatone in the apple app store. Sync your google voice number with talkatone and you are good to go. You can use the personal hotspot to link your mac book. As for prices you will just have to determine what plan you want once you get here. Hope that helps.

@lynn. Send me a private message and I will be happy to meet up with you.

I can get it unlocked for you for a small fee. I have had mine, my wife's and many of my friends phones unlocked. It works fine when I return to America because it is a factory unlock. I hope your phone is GSM, cant help if it is CDMA. Send me a message if you want.
