Thanks Josh. I'm trying to combine/simplify systems. I have a just under 3 year old Global world network phone that was totally useless in Europe last week since data service is now 4G. My phone was still 2G/3G. Texting and calls worked fine, but no data. Had to find Wifi continuously. Luckily, it is more available in Europe than here, even on trams and buses.

T-Mobile is offering free data and SMS on their 55+ plan in 140 countries. That would work fine for me, and then I could just keep my obsolete phone for occasional calls.

It's time for me to upgrade local cell service here anyway, so a new phone is coming one way or another.

GSM and CDMA are both 2G voice technologies. All 3G and 4G smart phones use the same technology. Different carriers have different frequency bands and phones have carrier specific frequency filters.
