Moving there in mid December, for good. Currently live in Vegas with a verizon iPhone and Verizon service. Do i just cancel the verizon and get a new sim card, or what is recommended for cell service?

At home (Canada), I use an app called textme - my cottage has poor cell coverage but I have wifi. So I call forward my cell# to my textme# and that way I receive all my calls over wifi. This would be great to use in Thailand, but I have a feeling it won't work there? Or are there other similar calling apps that work in Thailand? Or would I need a VPN?

For past trips I subscribed to Skype's unlimited calling ($3 per month) which is great for making calls to landlines, but for people calling me, I end up just calling up my voicemail periodically to see if I have any messages since there is no way to get notifications. It would be awesome if my calls just rang through to a web-based calling app like textme.

TIA
