Carol,
I would go for the tri-mode if the specifications are what you are looking for. Verizon is eliminating anolog in the near future but as long as it still exits why not be able to use it. When we were in Alaska a couple years ago I had Verizon and my sister in law had T-Mobil which is only
GSM. My phone was a tri-mode and I was able tol make phone calls where she could not. Maybe it was because of
CDMA and maybe because of my being able to use the analog. I now have a global phone and had to give up the analog and go 100% digital for being able to switch the phone back and forth from
CDMA and
GSM. It is an expensive phone but with renewing the contract, it cost me $100. Verizon is a littlel more expensive to make calls abroad but the phone worked fine in
GSM mode from Spain.
I guess I answered more than you asked but I hope this may help you if you have not already made up your mind.
Good luck, Dick
