I'm trying out a new TP2-CDMA from Telus (Canada) and this is by far the best system I could ever try in my case. I've always been a GSM user (since 1994) mostly because it gives you the latitude of using what ever device you want just by inserting your SIM card. so I got the Phone Inserted my Rogers SIM in it and it got me on the Rogers network right away I then activated the phone on the Telus network and it is also working fine... of course...
But the best thing is that I set it on "Global" network and it stays on GSM (Rogers), and when I get to an area where there is no GSM signal it switches by it self to the CDMA (Telus) network!!! this is amazing! NO MORE DEAD SPOTS! Of course you need to have two Service contract from two different service provider, but if you absolutely need to get service in areas where your current provider does not offer any, well it sure beats the hell out of having two different cellphone in your pocket... I have set my main cell number to transfer to the other on "No Answer after X # rings" and I get all my calls no mater what network I'm on!
The only down side to this TP2-CDMA Unit is that Telus got rid of a bunch of stuff that is in the TP2-GSM... like the GPS for instance... Well I guess you can't have it all...
I got Bing to work... so there is a GPS.... but Google Maps won't work...
Just thought I'd share my joy...
there is a telus gps registry fix on pccgeeks.
GPS works... i have google maps, tomtom7, and bing running fine, but sometimes, getting a lock can take very long
still new to winmo, so not too much going on with the phone, but am learning =b
zedex26, you are right!! there is a GPS!
The only thing is that I can't make Google Maps to work... it instals but when starting it it keeps on saying Loading... and never opens.
Anyway now were talking!! it has almost everything I was used to... But NO "Camera Flash" not that it was so usefull as camera flash but as a "FlashLite" it was...

in google map
go to menu -- option -- gps setting -- use manual com 4
go back in option select "use gps"
close
reset your device
should work
inspireqc,
I finally got GM to work... Don't know why but the device needed to be on the CDMA network in order for the program to load... because on the GSM network, the program does not even load... it keeps on saying "Loding" and I could not even access the program... It's like it does not see the data connection...
Anyway There are other maping SW that work very well on both network on that particular device.

I've found that I have to manually switch the data connection in order to use Google Maps when I switch between GSM and CDMA. It does work w/ both, however it's much better when I'm on Telus b/c this TP2 can't use Rogers 3G network. Keeping my fingers crossed for when they finally crack this baby open and hopefully find that the North American 3G freqs are there.

Did you have to sim-unlock your phone first?
My friend looked up the technical specs of our chipset and they do support North American HSPA but it is not available, either by a hardware or firmware\software lock.
WOW
GSM and CDMA both work... that's fantastic.
Does this mean that it hold 2 different SIM cards? Or is the CDMA part devoid of a SIM card?
Would it be possible to use a GSM SIM card from any provider around the world and reconfiure the CDMA part to work with any CDMA network around the world?

well i would think it would be a radio issue have the same with mine. use it strict on rogers. i also looked up a little but the tp2 telus is 800 and 1900mhz hspa and rogers system is 850 and 1900mhz hspa so the frequency may be a issue as well.
anyone know how to fix the caller id name problem while on gsm?
Canadian folks, or TP2 users in CA, i have a Sprint TP2 thAT i would like to get to work in CA, what is the best scenario for both voice and data,thanks a lot

for sprint phone i would stick to telus or bell unless you can put a sim card in your phone then your looking at rogers and the cdma global phone wont work on 3g rogers just edge
Thanks hiwire men, Sprint TP2 is a World phone as you know and will take any SIM, so you saying it wont get 3G with Rogers? why is that, is it Rogers or what is the reason? and hand how is Telus and Bell do it, they just input it in their database and bam, or will it require some ROM flashing. thxxx

after reading up if you want 3g on rogers network you need a tilt 2 do to the fact rogers uses umts/wcdma 850/1900 mhz sprint is 900/1900 BUT the edge network will work on your sprint phone to rogers other then that it is it. rogers is doing alot of work on their 3g network and i think most of the fido network is 1900 mhz and rogers is 850mhz 3g but i think personally it may work in the future but not gonna be anytime soon. The 3g should work on telus and bell and might on fido ill have to see my friend and try it out. but i know for sure right now it dont work with rogers.
thank again, I do not have any FIDO preference, I assume coverage with Telus or Bell are about the same.So just walk the TP2 to the TELUS or Bell store and it is done?

I know this is an odd request, but is there anyway to use the internet while talking on the phone. Normally I wouldn't care but I'm tired of the iPhone goons hassling me about it since those new commercials.
If not would there be a way if I unlocked my phone for GSM so I could talk on one frequency and surf on another?
Please direct me to a link if this has already been answered, I searched and didn't find anything.
Whoo boy, the old GSM vs. CDMA debate. No to your first question; it's a technology limitation of CDMA, which is why AT&T loves flaunting that fact. GSM also has the leg up in the number of simultaneous connections for conference calling. If you're looking for ammunition, CDMA generally enjoys better penetration of structures, and I know that I have found my service on Sprint to be stronger and much more reliable than my old plan with AT&T. Some people would even say that CDMA offers better call quality than GSM, but that's a huge debate with opinions on both sides. Also, GSM's encryption method was cracked recently, making calls potentially more vulnerable to eavesdropping. Finally, even when I had my old Tilt on AT&T I don't think I did too much surfing while talking on the phone; I really don't think it's as amazing a feature as they make it out to be.
For your second question, the CDMA Worldphone edition Touch Pro 2 used by Verizon and Sprint does have a GSM radio, but the question has been asked before if both networks can be used simultaneously and I believe the answer is always no. Anyone else feel free to correct me if I'm wrong.
last I checked in order to use cdma/gsm phone networks at the same time can't you just pop in a sim card!!!!!

one word IMPOSSIBLE!!!!!!!!!! GSM and CDMA are hardware radios an unlock is IMPOSSIBLE unless the phone is a world phone with both CDMA and GSM but your phone doesn't qualify so try getting a GSM/CDMA hybrid and then come back to me. However verizon will upgrade to LTE which is GSM based!!!!!!!! watch em LTE will allow voice and data at the same time. When LTE upgrade is complete say goodbye and good riddance to CDMA it will be shut down soon!!!!!

qjsmartphone - I thought that the TP2 was a world phone and thus held both antennas for cdma and gsm?
trogdor1138 -thanks for the input.
now I'm with sprint, and they offer 4G. This may be an ignorant comment, but can't a world phone with both antenna's say call on cdma and use the 4G provided by sprint? Or am I missing something? I kind of new at this so forgive the question if it is stupid. If there is a wiki on it please give me the link and I will be glad to read up. Thanks

I'm not sure what you are talking about, but CDMA variant of Touch Pro 2 does have both GSM and CDMA hardware in them.
Also, LTE and WiMAX is a two new 4G technologies that will eventually replace 3G data.
LTE is not based on GSM, they are two different communication technologies.
Back to OP's question, if you are using CDMA branded TP2 you cannot surf and talk at a same time. It is limitation on CDMA technology.
4G and 3G is not compatible, is your grandparent's old 2G phone do 3G? no.
How about your 3G phone accesing 2G? yes. Usually when newer technology is being deployed, they make sure that it is backward compatible, so that they can lower battery consumption and remain accessible to area where new technology is not yet available.
Just be near wifi and then show them you can surf while talking.

Or pop in a ATT or T-mobile SIM card and switch to GSM mode. The phone IS capable of voice and data when using GSM.

I'll jump in here...
I thought Sprint/Verizon phones with both GSM/CDMA radios cannot use AT&T nor T-Mo SIM cards. I thought they only accepted the GSM SIM cards of countries outside the US.
Wait... HardSPL fixes that, doesn't it?... Oh well, I think I should stop stalking the CDMA forums when I have almost no idea on anything CDMA-related!
But, I'm still in favor of the WiFi suggestion!
mac people live in their own little world. don't let them bother you. sure, they can talk and surf the web at the same time...if they have 3g coverage. but there are areas where they have no coverage at all let alone 3g. then they can use the 'paper weight mode'. i also love how they tout their app store meanwhile we've had multiple wm app stores for years already. also i get to choose what apps i want to use without htc or sprint telling me what i'm allowed to.

i think you can use any SIM card you want if you phone is SIM Unlocked
yes you can use any sim card if your phone is sim unlock buy the Sprint TP2 is not working with us 3G
unlock
I called up VZW and told them I was going to Europe and wanted to use prepaid SIM cards instead of paying Big Red the $$. They gave me the SIM unlock code and now I can use T-Mo or AT&T SIM cards with no problem. Only downside is that their GSM frequencies are slightly off from the rest of the world so no high-speed data when using VZW on GSM carrier in the states...

The Verizon TP2 has a simple SIM lock on it which is similar to standard GSM SIM locks. Remove the SIM lock and you can use any SIM card with a compatible network, including US networks.
The Sprint TP2 doesn't have a standard SIM lock, but instead has the US frequency bands disabled. Hence the need for a new radio.
Ok, so I've searched all over and haven't had much luck. I have no experience with cdma phones, as t mobile is all I've ever had.
I was given a new US Cellular HTC Hero s. I opened it up and saw the sim slot and though, sweet I can replace my sensation with it (I smashed the screen pretty bad). Well, that was a no go, as the phone is cdma. Looking online though, I see it can run in gsm (options global mode, cdma mode, gsm / umts mode. I unlocked the bootloader using the htc site (not sure it matters) and popped in my sim card again, and tried both global and gsm mode, though neither got signal or would dial out. (under networks, it had the tmo apn info.)
So, is the GSM mode offered on this phone only for non US bands? Would a custom rom (now or down the road) allow it to work on tmo? I read something about the HTC Merge and someone being able to switch out the modem in the rom that allowed it to work in the US, but that is well beyond me. I can follow instructions, work ADB and flash roms.. but thats about it.
Is it possible, or will it soon be, to have this phone work on GSM or am I just stuck trying to sell it as a us cellular phone (or perhaps another cdma carrier.. like I said, I don't know anything about cdma)
As a Canadian I'm not sure about who owns US cellular or if they are their own company but I'm guessing they work like Verizon world phones. They have sim card slots but will work only outside of the US. If those verizon phones are used within the States, they will only pick up Verizon's frequency, as opposed to T-Mobile or AT&T where you can unlock them and use them with any GSM carrier within the States. But yeah, you can unlock it and it will work with any GSM carrier outside the States but within the States I think it will only work under US Cellular CDMA network...please correct me if I'm wrong.
That's right, u.s. cdma "world phones" have gsm radios but are locked down from connecting to gsm networks in the u.s. This is not just the normal sim lock found on gsm phones but they are hard coded to ignore u.s. gsm networks.
Some have been unlocked to work on any network through various methods including flashing a modem from a non-us varient of the same phone and other hacks. I can't comment specifically on this phone however.
Sent from my SPH-D700 using XDA App
Well, that points me in the right direction, and confirms what I read about swapping modems (on the other phone mentioned).
So basically it's software telling it not use a certain frequency, and not that the phone itself is incapable of picking it up (had my doubts about that)
Pretty shady the way phone companies are allowed to operate (don't get me started on my unlimited internet in my contract [pre data caps in tmo]. "Hey! check it out, this phone uses data 5 times faster than your old one, oh, and you get half as much too) sorry, end of rant.
I'll keep searching, and post if I find something..
On a side note, can cdma phones be flashed to another cdma carrier like verizon or sprint, or is it the same deal, coded to only use a certain frequency range?
only thing I've heard of is flashing sprint and verizon phones to cricket, metro pcs and boost.
Got my FIDO Razr HD. Rogers SIM = all is good. AT&T sim = asks for unlock code, which i buy online.
After entering code, phone appears to do a factory reset. During the reboot, a box pops up:
"SIM not allowed MM #3"
Now the phone permits "Emergency Calls Only" with the AT&T sim. Rogers SIM = still good.
When I put AT&T sim into my other phone (HTC desire) it works fine on roaming (rogers network). So I know sim + signal is fine.
Don't understand this error message.
Did I mess up the unlock?
advice appreciated, thanks.
Do you have another Canadian SIM you can try? Bell/Telus etc?

Thanks for the replies everyone. to answer the questions:
1) i don't have any other sims right now: just rogers + ATT. Next time i am w/ friends I will ask to borrow telus/bell microsim.
2) they were regular sims that were cut down.
3) haven't had a chance to visit USA since posting topic- but when i do, i will test both cards and also visit an AT&T shop to bug them about it.
Is sim corrupted? I don't think so because it works fine in HTC desire. But I guess trying a new one will prove or disprove.

I am using this phone with at&t with no problems, I took my sim out from my iphone 5 and used a adapter to go to micro sim and it works fine, no issues.
I'm receiving a Fido RAZR HD to be used with AT&T this afternoon, I'll let you guys know if there are any issues.
OOI, is AT&T seen as a much better GSM network than T-Mobile in the US?
I was looking at the T-Mo USA site, and there are some amazing "Monthly4G" SIM only plans (e.g. $30/month for 100 minutes, unlimited texts and 5GB of HSPA data).
This seems much better value than AT&T, Verizon and even Sprint! But is their network sketchy compared to the others?

AT&T offers the second largest network coverage behind Verizon. They are also one of the two GSM carriers in the United States, and tend to be more popular with mobile phone enthusiasts because their UMTS bands are more common and used with other regions such as Canada or Australia. T-Mobile does indeed offer excellent value, but they use mainly AWS band in addition to PCS band in selected regions, thus making them the lesser choice for using unlocked phones from outside the country.
Hey,
Just looking on wiki:
http://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
It looks like T-Mo mainly use 1900 for 2G and 1700 for 3G, whereas AT&T use 850 and 1900 for both 2G/3G, right?
So if I bought a Canadian Razr HD XT925 and came to the US, would I be able to use T-Mo's 3G network? I am guessing no, since it does not support 3G on 1700MHz.
But then there is a note on that Wiki page saying that they now have a roaming agreement with AT&T after the failed acquisition. So if I forced the phone into "WCDMA only" mode from the test menu, would it then fall back onto the AT&T 3G network?
Sorry for taking the thread slightly off topic
Cheers,
Su

As you have read, T-Mobile did acquire PCS bands from the failed merger with AT&T, but these bands are not as utilized as their 850 MHz band so it's not as widely available as you may think. Some areas might be able to use the 1900 MHz band for T-Mobile 3G, but I would check with fellow T-Mobile users to confirm first before you dive in headfirst. I know that there are T-Mobile users in the Dallas-Fort Worth area that are getting 3G data connectivity with their unlocked AT&T iPhones.
Well T-Mo do daily plays for like 2 bucks right, so I can always try this out before committing to a contract
Do you think AT&T would be the better bet if I am bringing my own device from Europe?
The reason I ask is that I may be coming to a US college for a couple of years, so naturally, I'm planning ahead to see if my phone will work over there

Well T-Mo do daily plays for like 2 bucks right, so I can always try this out before committing to a contract
Do you think AT&T would be the better bet if I am bringing my own device from Europe?

If you're using a device from Europe or Asia, then yes, you have a much higher chance of being able to get 3G connectivity with AT&T. Off the top of my head, Nokia seems to be the only one that tries to actively keep AWS band in their radios.
Hmm, so I did a bit of research on GSM Arena. Seems the Nexus line of devices consistently support 1700MHz 3G (including the Nexus S which I currently have).
Guess who cancelled their Nexus 4 order last week, and opted for a Canadian RAZR HD instead...
Whoops
Hi all,
With Verizon releasing officially, the update making its SGS3 Global ready atleast for voice as of now, a lot of discussion is happening right now about the Global capabilities.
FYI. I'm a good reader and explorer on hofo,androidforums and xda. So any guidance is highly appreciated
So here is my question.
I have a Verizon S GS3. It is brand new.
1. Can I use it with Straight Talk T-Mobile SIM ( T-Mobile has good coverage near my house ) after doing the rooting, unlocking, etc. etc all the technical stuff
2. If I unlock the phone, will it be truly global capable, I mean, can I use my S GS3 on any GSM Network in the World, even in the USA, with 3G Speeds? Did anyone use it in any Country with 4G LTE Speeds?
3. I know this is really a very very strange question. But after unlocking the S GS3, will it be working on the AT&T LTE Netowrk in the USA? My thinking is, if it working in the LTE Network in the USA, then it will work in other countries as well, where LTE Network is going to be available in the future. Sorry, I know this is a bit weird.
If You can please refer and threads or links, it is fine with me. I'm also looking and not depending only on the answers that I get from this thread. But looking for replies/guidance/links though.
Thank You.
hope this is the answers you are looking for

for Q1:yes you well be able to use any network... install any mod now most of them are already rooted and unlocked
for Q2:yes you can... all you need to ddo is to download a program called hiapn.. wipe the existing apn settings.. then auto detect and you are good to go 3g and hspa
Q3: yes it works thanks to the magic of hiapn software... but not many countrys use LTE .. usa canada japan and maybe few others
Verizon SGS3 on any GSM Carrier
Hi experts,
I have a small doubt here.
If the Verizon SGS3 can be used with any GSM Carrier around the world, then that means, the Verizon SGS3 can be used with AT&T or T-Mobile as well along with Verizon Network.
But the T-Mobile or AT&T Versions cannot be used on the Verizon's Network. Is that true?
I'm have got a traveling assignment coming up to Europe this Summer and I need to know what is the best possible solution out there before I leave.
Thank You.
Verizon's GS3 uses CDMA technology for the phone calling and data, as far as I know the SIM in the verizon version is only used for LTE.
From what I have read in forum posts, (this one in particular http://forum.xda-developers.com/showthread.php?t=2013647) if you pop in a SIM card, calling and texting should work. If you want data to work then you need to change some APNs around. Stock touchwiz does not allow this so you would need an app to do that. AOSP ROMs should have a way for you to edit APNs.
On the topic of getting 4G on any other network besides Verizon, that is fairly unlikely as they all use different technologies/ bands. Verizon has LTE, T-Mobile has HSPA+, not entirely sure what AT&T has but I think its also LTE.
This phone will take any SIM card cut to micro-size.
3G+ speeds depends on the frequency the carrier uses. The VZW GS3 uses the following radio frequencies after the JB update: GPRS/EDGE/GSM (850/900/1800/1900); HSPA/UMTS (2100) [I had to search high and low to find this for my trip to China]
Each LTE carrier uses different radio frequencies, and global countries also use LTE frequencies different than the US ones. 4G is a very varied standard at the moment.
If you want fast internet on a non VZW carrier, it better have HSPA+, otherwise you are on 3G at best.
Right now, the only truely global phone is the iPhone5 on VZW, which supports 5 different LTE frequencies. Sad but true.
The US based SG3's dont even have the FM radio that the international versions have

Yeah, my girlfriend has a verizon s3 and with straight talk she is only on edge it never changes. It makes the phone nearly useless. Ive tried to talk her into letting me flash and unlock it but she isnt real interested in it. I dont even know forsure if unlocking the bootloader downgrading to 4.1.1 and using the att sim unlock method would work but I would assume that flashing it would allow you to at least get 3-4g. not?
