This might be a stupid question, but can 3g phones from Japan work in Europe??
GSM phones from different parts of the world are not always compatIble!!

If the phones work on the Euopean frequencies of 900/1800 Mhz, Yes. If not, no.

The problem with your theory is that there are many nations around the world, including your own, which have a great number of people who cannot afford current 2.5/2.75G mobiles, let alone 3G mobiles and I presume that 4G mobiles will be even more expensive again.
In addition to the necessary consumer spending required there is also the factor of the networks having to upgrade, yet more money.
@harryville
European 3G mobiles are able to roam in Japan, both 3 and Vodafone utilising Vodafone's WCDMA network in Japan, consequently, Japanese 3G mobiles can be used in Europe.

To add some more point that in the usa people prefer using 2g(tdma, cdma) more than 2.5g(gsm) also 3G is better than GSM IN MANY aspects like in india while downloading stuffs using gsm phones we get that temporary error msg but in 3G the whole thing is real time its like so fast that it seems that you are sitting next to a cell tower a perfect seamless connection :-)

@scots. Very true, the point you raised there. For example, the only 2.5g network we have is the newest: it was implemented from scratch. The others who started with 2g are yet to make the kind of profits to justify network upgrades at the moment.
Again, even if any of the 2g nets decide to upgrade, therez no way they will make a dime on 3g, in line with the issue of affordability & customer perception. Thatz why I said I aint seeing 3g showing up here.
But then the issues you raised certainly blow a hole in my theory

Thanks for the info.
I knew about GSM networks but was unsure about 3g

@scots. Havng said that, the 2/2.5/2.75g platforms being a progression, we have some 2g phones that are more expenive than some 2.5g phones, for example. The implication is that we may have a scenario where price differentials in 3g sets & 4g sets may not be necessarily vast.
I am not certain of the tech details behind 4g, but I suspect that it will be a progression of 3g. GloMobile here bypassed 2g entirely and are recording good success. We really could end up with a situation in which one or more networks here and there actually bypass 3g & implement 4g.
That again, of course would depend on certain factors, including speed of development of 4g.

Who in Negeria would use 4G? With respect, is there a mass market for data services, which one would have to pay for? Does Nigeria have the infrastructure and/or culture necessary to promote and enable data services to expand? Does the average Nigerian sit in coffee houses each day texting friends; or have enough disposable income to facilitate buying ringtones, wallpapers, themes, etc on a regular basis; or take part in mass television/radio texting events; or travel abroad on a regular basis to make video calls a necessary feature to remain close to friends and family?
Part of the reason certain mobile technologies haven't taken off in the U.S. is precisely because of a lack of the necessary mobile culture, which underpins such technology.

@scots. Here are a number of factors that have generated a strong mobile culture (including data services) in the last 3 years:
1. High cost of acquiring PCs & accessories
2. High cost of acquiring regular narrowband & broadband internet access
3. Comparatively lower costs of acquiring & servicing mobile phones
The above factors have already given rise to a strong mobile data culture, including mobile banking & payments, mobile info access via SATK, CSD & GPRS, among others. These are realities on ground.
A growing number of small businesses (including mine) harness the potentials of mobile data services to compete effectively against the large corporations. More ppl are ccessing their mail at home & on the move via GPRS (one of the factors for the remarkable growth of the newest network Glo, which now has appx 2m subscribers after 1 year of operations).
The possibilities are enormous, really. Of course, there are no guarantees.

What percentage of the Nigerian population uses those services though? What percentage, of those who do use such services, do so on a regular basis? How much money is being generated by the use of such services in Nigeria? Would any of these figures be great enough to support any of the Nigerian networks leaping ahead to 4G?
The other factor to take into consideration is the fact that many manufacturers will not want to make expensive handsets for markets, where only a fraction of the population have the capability to purchase and use those handsets. 3G handsets are very heavily subsidised in Britain, the 3G networks hope that revenue from data services will be enough to earn such subsidies back. Would the Nigerian networks be able to offer such subsidies and would they realisticaly be able to recoup them?
Perhaps a pan-African network might be in a better position to offer advanced services in select African countries. Africa has an image problem when it comes to attracting investment; which networks or manufacturers would want to set up in Sierra Leone or Zimbabwe, for example?
3G would actually help to standardise services around the world, if it became popular enough. The availability of advanced services in the industrialised nations could mean that developing nations gain the same services as tourists and business travellers from the industrialised nations come to expect them as standard, providing impetus for the networks in the industrial nations to invest more in developing nations.
