We'll comment more on 3G issues when things stabilize been a clearer picture.
Part 5 of an call part series - click for Parts One Two Three Four Five Six Seven Eight Two frequency bands are used by GSM services in the US. In October 2005, discussions became public for developing a fifth voice frequency, in the story MHz band. Summary There is an easy answer to the question of 'Which bands should my Gsm cell phone support? MHz will give you be coverage in countries that also have 900 MHz. As the table suggests, 900 MHz is Band Gsm Phone Quad most common band used internationally. For comparison, when you have your FM radio Quad Phone Gsm Band to a radio station at 98.

- All international do that have the US frequency bands have 1900 MHz service.
A very few might have some 850 MHz service. In the past few years, service providers have increasingly been adding 1800 MHz coverage, due to congestion in the MHz band. But are still rare and expensive.
Which frequencies do you need when internationally? But due to limited and high cost, many people will prefer to choose a tri-band phone. Do you need both frequencies in US?
If you're listening to AM stations, they are in the AM radio band, between 0. Some bands more useful than others, depending on where you travel. If you see someone referring to a with 800 MHz service, they probably are simply mistaken and mean to refer to the 850 MHz band.
That depends on the countries plan to visit. Help this Site Thank you for your interest in helping this site continue to develop. When we first wrote this in July 04 we said 'there are only a very few quad-band phones for at present, and they tend to be expensive'. Ideally, you'd want a phone can work on all four bands - commonly called a quad-band phone.
And then, looking further into the future, is possible we'll see 1900 MHz coverage duplicating the 850 MHz coverage. Caution - Different definitions of 'Tri-band Phone' tri-band phones obviously?
- Unfortunately, most GSM phones only support two or frequency bands.
- Ideally the best solution is get a quad-band phone with all four bands.
- This really depends on the in which you use your cell phone.
- Note that countries with both 900 and 1800 MHz service generally provide better coverage in the 900 band than in the 1800 MHz band.
- Refer to the table below to get a feeling for which countries which frequency bands.
