Yes. GSM = GSM. The protocol is the same in Europe as it is in the USA.
But there is much more to it than that. Skip raised a good point in an off-forum e-mail to me - the GSM frequency differences.
The frequencies used by some GSM phones and service providers are not the same in all countries. That is an issue you need to be aware of. I got more curious and here’s a brief summary of what I found – hope it makes this portion easy to understand:
GSM cell service in the US (also Canada, Mexico, Japan, Korea and a few others) operates in the
1900 MHz frequency band and also 900 MHz. Most, but not all other countries have GSM systems in the 900 MHz band with newer service being added in the
1800MHz band. “They” are calling 900 MHz and 1800 MHz the GSM International bands while referring to 1900 MHZ as the US Band. There is also new GSM in the US in the 850 MHz band (formerly used for some analog cell calls).
The bottom line: Today, you need a “triple-band” GSM phone that operates at 900/1800/1900MHz for maximum US and international compatibility. To make things even more confusing the term
“Tri-band” cell phone does not always mean the same thing
. So, if/when you get a Tri-Band GSM phone make sure it covers the three GSM bands mentioned (900/1800/1900). There are some very few Quad band GSM phones that cover the 850/900/1800/1900 MHz bands.
Here’s a quote from the Nokia web site: “ Tri-band GSM cell phone (operates on 900/1800/1900 Mhz frequencies) works on GSM networks in approximately 140 countries and gives you the ability to stay in touch even as you travel around the globe. GSM network coverage and roaming ability is operator dependent and not available in all countries or areas. Check with your mobile service provider about roaming and coverage areas”
