cell phone in europe/US?

Question

i heard that certain phones bought in the US wont work in Europe because they use a different system, is this true? what are the differences?

Answer 1

Yes, this is true. The difference is the frequencies the phones operate on and the digital technology. Europe uses GSM digital technology and the 900 MHz and 1800 MHz frequency bands. The US uses many different digital technologies including GSM, but also CDMA, TDMA, iDEN and also Analog still in areas. The frequency bands are 800 MHz (sometimes listed as 850 MHz) and 1900 MHz (or PCS). US GSM carriers like Cingular and T-Mobile have phones which will work on the US and European frequencies. If you get one of these phones, you can use it in both places, provided the carrier has a roaming agreement (usually does in most countries these days), and that your line is not barred from international roaming. Even the carriers who don't use the same technology usually offer handset rentals for trips overseas. Verizon even offers a couple special handsets that use their CDMA technology and also take a SIM card for GSM use internationally.

Answer 3

In europe we have the gsm system, i think there are only 2 states in the US that have that. to have a phone working here, you will need a gsm compatible phone, that is capable of at least dual, if not tri-band, also, your phone should come with a SIM card.
If none of this means very much to you or your phone supplier, you are in a state that doesnt have gsm yet, what most people do is buy a pay as you go sim card and phone whilst they are in europe with a local number, will cost about $125 for a cheap one.

Answer 4

That's true as well as in vice verse... Cell phones are put on frequency's... there are different frequency's in US/Europe. Some cell phones are lock and pre-set to work only in one place. They do this so you don't buy phone wholesale in one place and sell them for mucho bucks in another. Other phones work pretty much anywhere in the world.

Answer 5

Cell phones in the US operate at a 1900 Mhz band of frequencies.

In Europe operators use 900 and 1800 Mhz bands.
Most cellphones sold in Europe are dual-band cellphones working on both.

So if you want a cellphone that works is US and Europe you need a 'tri-band' cellphone that can operate on all three frequency bands.
