Nokia E75 no 3G access in Canada - Upgrading, Modifying and Unlocking

Hi, i purchased a nokia E75-1 from asia and can not access 3G network here in Toronto, Ontario, Canada. Funny thing is that when i was in Windsor Ontario my phone showed 3G and I used 3.5G internet.
My service provider Fido says they support umts 850/1900 mhz . My phone supports umts 900/1900/2100mhz. So my phone should be able to access 3G on 1900mhz but for some reason it does not in Toronto and does in Windsor on the same Fido network. Windsor is also in the same province so i am very confused. Is it because Windsor is close to USA?
I also upgraded my SIM card to 3gSIM but still no luck.
Any ideas on how I can access 3G in Toronto? When i switch my phone to UMTS mode it loses Fido signal. On Manual operator search it shows 3GPlus and CAN221 which i can not access.
The North America e75-2 version works on 850/1900/2100. Is there a way i could unlock the umts 850mhz frequency on my e75-1
Thanks

if the provider use 850 for 3g everywhere or even just somewhere you can't
access 3g on the phone these places or all places
operators can change which frequencies they use in different places if they wish
if they depend on phones being able to use both 850 and 1900 users would never
notice

Help! 3G is not working after Hard-SPL and unlocked TP2

I'm new here and I enjoyed this site very much. I have one problem with my TP2. Somehow, 3G network is not working after I installed Hard-SPL and unlocked T-Mobile TP2 switch to AT&T sim card. Everything is working fine with AT&T's sim card I was able to made phone calls, received, SMS, and web browsing. ATT 's 3G network is available around my home, but I can not get 3G on TP2 instead a EDGE network. Can unlocked TP2 handle AT&T's 3G network? or a .cab file I can download to fix this?
idk for sure but i think t mobile uses a different frequency for 3g from at&t so if they are you are stuck with edge speeds on at&t man sorry
I have the tmobile TP2 and i can confirm from talking with ATT that the phone does support ATT BUT i was unable to use the phone on 3g. The phone DOES support the signals for 3g but am still unable to access the towers in my area. I think the phone may be hard set to look at tmobile towers, is there any way i could reset the device to open up its tower usage? Hopefully i can get an answer but no tmobile TP2 users arent screwed in the US we just need to find a fix
It was my understanding that the tmobile tp2 does NOT have 850/1900mhz 3g on it. It does have aws 1700 for sure. Not sure about 2100mhz though for overseas.
This issue has been covered many times in the numerous AT&T threads on this board.
I'm sorry to tell you that the T-Mobile TP2 hardware radio was limited to using 3G over the 1700/900Hz frequencies, while AT&T currently uses 1900/850Hz only. It's unlikely that any change can be made to the radio software wise to fix this issue.
Just to make things clear the issue has nothing to do with Hard SPL or custom roms.
T-Mobile UMTS 1700/2100 Mhz
T-Mobile 3G runs on UMTS 1700 up and 2100 down. Unless you have a device that runs on those specific frequencies, EDGE is the best you can do with T-Mobile if you opt to run on their service.
ATT offers UMTS or 3G using 850mhz(the old TDMA band) and 1900mhz. While T-mobile offers HSDPA (technically 3.5g part of the UMTS specification) using 1700MHz for uplink and 2100MHz downlink.
Because HSDPA is part of the UMTS spec, it’s backward compatable. However, you have the limiting factor beging that the frequencies the individual carriers use to transmit the data.
Europe and Asia’s 3G runs on 1900/2100mhz. North and south America is supposed to use the (AWS) 3G spec using 1700/2100mhz
ATT didn’t want to wait, like T-mobile is doing, for homeland security to vacate those frequencies and launched on 850/1900mhz instead

I heard that t-mobile did not have enough spectrum in many areas to launch 3g in its existing 1900mhz. At&t doesn't have that issue, or as bad.
Im gonna make this real easy for u. The tmobile tp2 will not work on at&t 3g. The 3g bands are different

American T-Mobile Touch Pro 2 and travel

Will I be ok travelling with this phone to Europe and Canada and getting 3G? Will the bands work? If not, is there something that can be done to make it work? I'm abot to get one and would like to confirm.
Thanks.

the t-mobile rhodium supports UMTS 1700 and UMTS 2100 so if canada and/europe use those bands for UMTS (3G) then yes it will work. If not, the device is quad band GSM so no problem using voice and EDGE for data.
Also make sure the device is unlocked if you plan to put another carrier's SIMcard in the device.

Not sure about Canada...but TmoUSA 3G bands are different than Euro-3G.
Unrelated, but worth mentioning: the T-Mobile USA international roaming charge for data is steep -- $15/megabyte.
If you got a Euro sim card that would fix the $, but not the radio (for 3G).
The T-Mobile version supports AWS and 2100 3G so works fine in Europe and most other locations. Had 3G T-Mobile and 3G Orange in the UK, but I would suggest a local SIM too. For the UK, both T-Mobile UK prepaid and Virgin UK prepaid work in a locked T-Mobile TP2 or get it unlocked for more choices.

You used a T-Mobile USA version of the TP2 in Europe and had a usable 3G data connection?? Hmmm...that's the first I've read of this.
If this is well-known (and if so, maybe I'm just clueless ) can you provide a link to more discussion, that is...uhh...evidence...of it? Not about what bands the USA version supports -- I know that part -- but other reports/disucssion of it actually working.
On the other hand, are there any reports of a Euro-TP2 that can work on 3G bands in the USA?
USA TMO TP2 will work on TMO 3G in USA. It may also work on WIND Mobile for 3G data here in Canada, not sure about voice as they are using some strange network setup.
As the phone is UMTS 2100 capable, it will get 3G data and voice in most places in Europe and Asia.

Have you tried a TmoUSA TP2 in Europe or Asia -- yourself -- and accessed 3G data?
I'm still doubtful, but I actually hope I'm wrong 'cause I'd love to be able to get 3G data on my TmoUSA TP2 while traveling in Europe...as long as I get a Euro sim card. Otherwise, faster data just means more roaming-$$.

Check the specifications. It supports both 1700 and 2100 UMTS. That means it will work in Europe. ALL Touch Pro 2's have 2100MHz UMTS and quadband GSM, every single one of them, including the CDMA ones. The carrier specific ones add certain bands.
European Touch Pro 2s have UMTS 900
CDMA Touch Pro 2s have CDMA bands
T-Mobile USA has 1700MHz AWS band
AT&T has 850/1900MHz UMTS
TP2 overseas vs versions
I believe, as I've use phones often in the US and overseas, that T-mobile uses 1700 UMTS in the US, but that their TP2 is also 2100 UMTS. Just as At&t Tilt uses 850 & 1900 UMTS (At&t requires both frequencies), but also has 2100 UMTS. As such, both should work in most European, African and Asian countries (verizon and sprint you,re mostly screwed).
I believe the older Tytn II (tilt) was sold world wide as a 850/1900/2100 phone, so you could basically buy it anywhere and use it here on At&t only for 3g or T-mobile Edge only. Unfortunately, the TP2 is sold mostly as a 900/2100 UMTS worldwide outside the US, so you are stuck buying the US versions that correspond to the US networks. The bonus of the At&t tilit 2 version is that it is 850/1900/2100, so it will work almost anywhere. The drawback of the T-mobile TP2 is that 1700 is used by almost no one and while you can use it in most of the aforementioned places, you can't use it in the Americas outside the US & Canada.

Just a note, I almost always pick up a pay as you go sim in other countries- much cheaper and very little hassle. Worth it for anything over a week stay. Maybe not as much so in some of Western Europe.

That is correct. Apparently they are only able to have 3 3G frequencies (though NTT DoCoMo is currently working on a chip that can handle 8 frequencies!)
At first Europe only used 2100MHz 3G and AT&T had set up on 850MHz/1900MHz. Since those were the only 3 bands, HTC would put all three of those bands in its phones up to the Tilt (Kaiser). Once they made the Raphael though, there was 900MHz 3G in Europe and T-Mobile had chosen the AWS band.
Since they can apparently only put 3 bands in, and Europe now needed two for 900MHz/2100MHz, they could no longer put but of AT&T's frequencies in. So they must have just dropped them.
The AT&T version (FUZE) has 850MHz/1900MHz and also has 2100MHz, which is the dominant band for 3G in Europe. I am not sure if they are using 900MHz there yet, but they decided that was more important to put in the European ones than AT&T's bands.
T-Mobile's 3G phones get AWS and 2100MHz. I think AWS might use 2 of the bands because it is split on 1700MHz and 2100MHz (but a different 2100MHz apparently, maybe low 2100MHz vs high, I'm not sure)

It doesn't just support 1700 and 2100, it uses both to work: 1700 for up/send and 2100 for down/receive. So, how does the Tmo USA radio cope without 1700 band for up/send when it's expecting it?

So, the full story (?) is that T-Mobile uses 1700+2100 (up/down) in the USA (which is what I already understood/knew) and in addition to that pair there's a separate slightly-different 2100 band that's used outside the USA? -- That, I didn't know.
If that's the explanation, that makes sense. But confusing that there's 2 different 2100 bands...
I may have to use some frequent-flyer miles and go check it out...

According to Wikipedia, UMTS Band I (commonly known as 2100MHz) uses 1920 - 1980 for uplink and 2110 - 2170 for downlink while UMTS Band IV (AWS, 1700MHz) uses 1710 - 1755 for uplink and 2110 - 2155 for downlink.
Band II (1900MHz) uses 1850 - 1910 for uplink and 1930 - 1990 for downlink and band V (850MHz) uses 824 - 849 for uplink and 869 - 894 for downlink. The uplink and download for these are close, unlike bands I and IV.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
I just assume they are only able to have 3 different frequencies since I have yet to see a UMTS phone with 4 frequencies. But as I wrote this, I'm not too sure because there were phones with Band I, Band II, and Band IV which would mean that there are chips capable for 4 different frequencies? Who knows, maybe someone with actual technical knowledge about this can say.
Also according to that page, there are five different UMTS bands deployed across the world. A bit of a pain. That is more then GSM ever had and who knows if it will grow to even more. LTE also will be coming in before GSM is phased out, so we are going to have to have phones that have GSM, UMTS, AND LTE. GSM will be no problem, quadband has been standard for a while, but having a phone that has both your carriers UMTS and LTE frequencies is going to be tough unless you buy it from your carrier.
What they should have done is just used the band names, and not their frequencies. It would be much easier to know that Europe runs on band I and T-Mobile USA runs on band IV and the T-Mobile Rhodium supports both Band I and Band IV.

ATT 3G Help me

OK call me foolish but I got fed up with TMobile and switched to ATT because the company offered to pay my data plan to keep me on call. I had been saying no but a billing problem that they refused to fix left me steamed. Anyway, is there anyway to make AT&T 3G work on my Tmobile TP2?
T-mobile is only edge...you cant use 3g unless you have a tilt 2

Let me rephrase that, for all the people that got "confusimacated" at first glance (like me)
The T-Mobile TP2 will work on AT&T's system, but it will only be capable of EDGE, and not 3G due to the fact that AT&T's and T-Mobile's 3G service use different frequencies.
Overseas Version
I have the overseas HD2 (LEO) which in not branded by T-Mobile. I also have ATT, can i get 3g on it?
at&t 3G is on the WCDMA 850/1900 megahertz bands. The Leo operates on EU frequencies, 900/2100 WCDMA for 3G service. Your Tmobile gets 3G on the 1700 MGHZ band. You need a phone with NA 3G frequencies to get 3G from at&t, and those are 850/1900 WCDMA. None of your devices will see 3G here in NA. Europe operates 3G on 1900 and 2100 and a few on 900 WCDMA, Japan and South Korea are on 2100 WCDMA only and NA is on 850/1900, so you need to be really careful of the hardware you purchase for it to work where you want it to and at the speeds you want. Edge comes on the older GSM frequencies and almost all phones have the 4 GSM frequencies, 850-900-1900-1800, but none have all the GSM and all the WCDMA frequencies, could but don't. Most US phones will have 3 WCDMA frequencies, 850-1900-2100. Better to buy an unlocked tilt 2 or sign an agreeement with at&t for a discounted phone.
Good luck.

Desire A8181 on Rogers

I picked up the A8181 in Hong Kong and am having some difficulty getting the handset to get any sort of high speed.
I've read through a few threads saying that not having the 3G/H icons is, simply, an icon issue. However, in my case, I can only get E (EDGE).
*#*#INFO#*#* -> Phone Info shows a Network type = EDGE
I have set the APN for Rogers/internet.com.
Any thoughts? Any successful Rogers users here?
Go to you Mobile Network setting and try to choose WCDMA only Network
I'm on Rogers too (well, fido) and i got the A8183 model because I know Rogers does not support 3G on the 900+2100mhz spectrum. I went through this crap with my Xperia X1i, but luckily Rogers activated 3G on the 1900mhz band to take advantage of visitors during the 2010 Winter Olympics (roaming data rates anyone?)
I may be wrong, but i'd say the future looks bleak for your 8181 on Rogers 3G. The A8183 works though, as it's from Telstra in Australia.
Do let us know if you end up getting it to work though!
Cheers

I'm afraid the A8181 wont work on Rogers/Telus/Bell 3G. Those networks use the 850/1900 MHz bands for 3G whereas the A8181 is 900/2100 (Wind Mobile uses those I believe)
For 3G on Rogers you'll have to get the A8183 Telstra model (as mentioned earlier )

[Q] Xperia Arc S work on Australian Next G Network?

Hello
I purchased this SonyEricsson Arc S on eBay. The seller was in Hong Kong.
On the ebay listing it states that the phone uses the following frequencies:
• 2G Network GSM 850 / 900 / 1800 / 1900
• 3G Network HSDPA 2100
I can get service in Perth, Western Australia but I work up near Karratha in the NorthWest part of the state. I lose service as soon as I get off the plane in Karratha.
I went to the Sony forum and they suggested that it may be a hardware fault so I sent the phone back to the seller and he sent it back to China and then back to me but it has made no difference to the problem.
I found an article on the web that says that the Telstra Next G works on the UMTS 850 network. Is it possible to upgrade the firmware on the phone to make it use the UMTS 850 network (the eBay listing says it uses the 3G Network HSDPA 2100).
Can anyone provide any other advice that may help me to determine what the problem may be with the phone and why I can’t get reception up here? Thanks
Daniel
I found an article (see below).
Looks like Telstra Next G used on remote areas uses UMTS 850.
Mine has:
• 2G Network GSM 850 / 900 / 1800 / 1900
• 3G Network HSDPA 2100
That would explain why I have reception in Perth (Telstra also uses GSM900 and GSM1800 to cover 96% of the population), but to cover 99% of the population (up here around Karratha) I need UMTS 850.
"Global System for Mobile - GSM
GSM 850 = Will not work in Australia as there is no GSM 850 network
GSM 900 = Standard for Optus, vodafone and Telstra GSM handsets
GSM 1800 = Standard for Optus, vodafone and Telstra GSM handsets
GSM 1900 = Will not work in Australia as there is no GSM 1900 network
In terms of GSM 900 networks:
Telstra provides 96% population coverage
Optus provides 96.5% population coverage
Vodafone provides 94.5% population coverage (this is extended to 96% population coverage via Telstra GSM national Roaming Agreement in regional Tasmainia and regional Victoria)
Technically Three (3) also provide 96% population coverage via Telstra GSM national Roaming Agreement, how? several GSM 900/1800 handsets do accept the Three (3) SIM card for service provision, also if you have a 3G handset (UMTS2100/GSM900/1800) you can set the network settings to GSM only and thus get Telstra GSM coverage.
Wideband Code Division Multiple Access - WCDMA (a.k.a 3G UMTS and 3G HSDPA)
Due to Telstra irresponsibility in naming their own outright 3G network NextG they have indeed confused the entire market place (not to worry Optus are not far behind with yesG and i cant wait to see what Vodafone call their extended regional 3G network)
Ok lets take a look at 3G.
Telstra 3G = UMTS 2100 which provides 60% population coverage
Optus 3G = UMTS 2100 which provides 80% population coverage
Vodafone 3G = UMTS 2100 which provides 60% population coverage
Three (3) 3G = UMTS 2100 which provides 60% population coverage
now the hard part:
Telstra NextG = UMTS 850 which provides 99% population coverage
Optus yesG = UMTS 900 which extends the current Optus 3G UMTS 2100 population coverage from 80% to 96% population coverage (an increase of 16%) Optus will eventully drop the brand name Optus 3G and use the brand name Optus yesG once their entire population footprint reaches 98.2% (which will be around july 2010 at current rate)
Vodafone?
The new regional UMTS 900 network was supposed to be up and running this month (January 2009), however they announced in october 2008 that the network builder Ericsson was taking time to get it bug free so their new regional extension network will probaly come online sometime around June or July 2009, which will extend their current 3G population coverage (which is UMTS 2100) to 95%.
Ok now that all that BS is out of the way to answer the question:
In the USA only one major provider has UMTS 850, and that provider is AT&T (used to be known as Cingular).
In Canada the big UMTS 850 provider is Rodges Mobile.
So essentailly a 3G UMTS 850 handset from those two providers will work here (provided they are unlocked)
Or the other way round is when buying from the USA simply ask, what network band they use for 3G.
If its UMTS 1800, nope wont work here
if its GSM 850, again wont work here
If its GSM 1900 again wont work here
If its CDMA 800 or CDMA 1900, again wont work here
So what your looking for is UMTS 850.
Also you wont find any UMTS 900 handsets in USA and Canada as they dont use UMTS 900 there."
You had to get an American version of the device.. now you cant do anything about it i guess
Sent from my Xperia Pro using XDA
You can't add a particular band unless it was there to begin with. It's hardware, not a software issue.
Your best bet would be to see if any of the other providers use the same bands as the phone. (It's unlikely though; Telstra has the largest network and most other providers are leasing their lines).

If you really wanna do something to make it work.. then pull out the radio from your phone and replace it with the one which comes in the American edition.. then flash the baseband for american version for your device.. and then ka-boom.. everything works..
But i dont think you are going to do that..
