Telus TP2 Radio(s)

Exactly what cellular radios does this phone [Telus TP2] have?
My carrier [Telus] has recently completed their 3G overlay, and I'm still showing "EV".
Should I be talking to them about fixing this, or...?
It was (is?) my understanding that this phone was fully 3G capable.

Can someone help me with this?
As far as I can tell, my phone should support the Telus overlay of HSPA on their CDMA network, however I'm showing "EV" an my network type on the notification bar.
I visited a Telus store, and talked to a rep, who just babbled to me about how my SIM was "registered" as a CDMA phone, and therefore I couldn't use HSPA.
>_>
Thoughts?
EDIT: The rep also fed me this convoluted bullsh*t about how when I'm roaming, I'll be able to be on HSPA networks, so I'll get better bandwidth roaming than on my home network...

Wow no one knows the answer to this?
I've searched, and there's no answer, per se, just descriptions of Telus' technology and the antennae in the TP2, which seems to indicate that the TP2 should be able to get on the Telus HSPA network...

I have a SIM-unlocked Telus Touch Pro2 I bought off Craigslist, figuring it'd be good to go when the HSPA network rolled out (Only four months later!). As I understand it, the telus model can make and receive calls on quad-band GSM frequencies, but only use EDGE speeds for data. Has to do with the firmware for the chipset inside the phone. The only HSPA 3G band the phone can use is 2100 Mhz, which is the bad used in Europe, not Canada. It's a major piss-off, especially when a month ago the stores made this out to be the top-of-the-line phone, perfect for ever and ever.
It would seem that should Telus decide to plug in some firmware upgrades, they could activate the new 3G bands, but why bother? We've already signed away our souls to the company.
Who knows, maybe they'll fix it when they release Windows 6.5 for our rig. Because that's on the top of the to-do list, right?

Well there are new radios that we could flash...would that change anything?

Now I may be misinformed but I think that the Telus version is a CMDA phone with GSM capabilites on some frequencies. I do not think it will work on HSPA in Canada as they use different frequencies (850 and 1900). This is why so many people were waiting for the ATT version to come out as it uses those frequencies.
Remember GSM does not equal 3G.

What I would like to know is whether the distinction between 3G and GSM is on the hardware side, firmware side, or software side. Telus would have you assume it's all the hardware's fault, but I'm not sure on that one.

From everything I have read its the chip in the phone that isnt programmed/capable of doing the frequencies required. It may actually be a second chip but I cant confirm that. Other posts have stated that there wont be a software fix to "unlock the frequencies" needed.
GSM is a cellular line and 3G is a data connection.

I just purchased an At&t Tilt 2 unlocked for use on Telus 3G+ network. The Telus Touch Pro 2 is a CDMA , Quadband GSRM and UMTS/HSDPA 2100. The Telus TP2 will only work with EVDO data on the Telus network. If you unlock it for use with Rogers it will work on GSRM with Edge data. That is why I have ordered the At&t Tilt 2. Unfortunately Telus won't honour my unlimited data plan and say it is only for EVDO and that I have to change to one of their current plans to have HSDPA. Like all of the networks, they get your money one way or the other. I'm pleased that with the Tilt 2 I am free to switch providers here in Canada and still get 3G as well as when I travel in Europe.

Questions about using a Touch Pro2 from T-Mobile on AT&T

So I have a Touch Pro2 on my personal T-Mobile account. My company has issued me a iPhone for my work phone. Which they pay for 100%. My question is if I unlock my Touch Pro2 and put my sim card from my iPhone in the TP2 will AT&T change my data plan to a PDA one? Since I do not pay my company phone bill I don't want to do anything to change that plan or add more money to it without permission. By the way the iPhone is mine so if I leave the company I take it with me. So I want to get the Touch Pro2 to work on my company line so I can sell the iPhone pocket some cash and cancel my personal line.

At&T data plans
the iphone plan and the PDA plan are completely different features and are not cross compatible. If the company bought you an iphone, in order to make the internet work on the TP2 you will have to have the feature changed out, if it is the company's account, you may not have that access to make the change, and internet won't work until it is changed.

You dont need a pda plan to use a unlocked touch pro 2 from tmobile i have one and im on att, the tmobile version doesnt register on the att network so the most they can charge is the lowest data plan. as far as your plan the iphone plan is probably the only plan that doesnt change on its own, although if you put the sim in your touch pro 2 youll still get data and still be charger the iphone plan. but remember your only get edge dta speeds with a unlocked version.

That is correct. Tmobile TP2 has different 3G radio hardware than ATT. I got a Tmobile TP2 and unlocked it to use on ATT so that they couldnt take away my $19 unlimited data plan. the Edge radio works and thats fast enough for what I use the phone for.

I have tp2 on att network also but i cant connect to aim or any instant messaging programs what should i do. I configured the settings to connect to the internet and it works.but i cant use aim,yahoo,and myspace im.

Well seeing as how my previous company phone was BlackBerry Curve running edge I don't think it would be entirely a problem.

Is it faster or slower?
HTML:

How different? Is T-Mobile chip is faster than AT&T chip or slower? If I'm with T-Mobile TP2 phone and AT&T service what will happen if I'll flash the latest AT&T stock radio on the T-Mobile phone?

3G on TP2 w/AT&T
Is there any way to get the 3G to work on my TP2 (unlocked T-mobile)with my at&t 3G sim card ??? It is so f***ing slow!
Please don't tell me that I have to buy Tilt 2 to have it work!

Buy a Tilt 2.

I just got Tilt 2!

You're taken care of now, but just for the record, the TMo and ATT 3G services propagate over different frequencies. The 3G radio in the TMo phone is tuned to transmit/receive 3G info over TMo's frequencies, and the Tilt2 is tuned to transmit/receive 3G info over ATT's frequencies. It's not a question of which chip is faster, but rather which chip can access which carrier's 3G frequency.
Most GSM phones have quad-band edge, meaning they can access edge-speed data on most carriers. But most branded GSM phones have only their particular carrier's 3g band.
Flashing the ATT ROM onto the TMo phone won't affect the speed of the 3g radio, as it is a hardware difference, not a software difference.

Thanks, I figured it will be easy to buy Tilt 2

damn it !!!
So are u saying that my tmobile phone will never work on ATT with 3G?? this is CRAP! if there is no hardware difference why cant there be a workaround ? radio related maybe to unable the phone to use ATT 3g frequency???

TMOBILE HTC Touch PRO 2 has different hardware -meant to read "band" specifically for Tmobile's 3g.
ATT TILT 2 has hardware specific for ATTs 3g network.
You can use Tmobile phones on ATT using Edge..but you will never get to ATTs 3g network. You simply just dont have the hardware. It's just like buying a phone that has not internal GPS chip and no matter how you flash it or add/remove software, you simply can't use the turn-by-turn navi software (unless you use an external bluetooth device).

Additionally, anyone know about the radio compatibility of a HTC branded TP2? I purchased mine already unlocked, and not sure if I can get 3G from ATT or not...

Yup, that is exactly what I feared...Good to know, and I Think mine will end up on Craigslist before long.

the reason the 3G wont work is because the 2 carriers use different basebands for service. While they both have 3G capabilites, ATT uses 850 and 1900 and Tmobile uses 1700 and 2100... it may have changed but i know thats what it used to be. It is the same reason that (forgive me for mentioning the dang thing) the iphone 3G wont work on tmobile, it will only work at EDGE speeds.

[Q] Moving S4 from Verizon to iwireless/t-mobile

Hi,
I am thinking about moving my Galaxy S4 and moto RAZR from Verizon wireless to iwireless (a t-mobile affiliate). I understand that I need to unlock my phone but I am unable to find out if I move it to iwireless if I will still have 4G data. The iwireless sales rep said that I will still have voice and 2.5G service but couldn't tell me if I would still have 4G.
I was looking at this table I found on a site explaining how to unlock the phone but I don't know enough about the subject to make an informed decision.
Samsung Galaxy S4
Can someone confirm whether or not my Verizon S4 or RAZR can be unlocked to work with the iwireless/t-mobile 4G network?

It seems as though your grasp of the subject is strong enough to know that it might work as you'd like - and it might not. You need to call back and ask to speak to a CSR that actually knows what bands their service works on so they can give you accurate information. That's kind of their job...
Also -
Verizon LTE operates on Band 13 while T-Mob operates on Band 17, both of which carry completely different spectrums; this means no LTE on either of your unlocked phones.There's a slim possibility that you will get intermittent 3G but the most likely scenario is that you will get talk, text and 2G / 2.5G only.

Band 17? My Verizon branded S4 is getting T-Mobile LTE. I'm fairly sure its on band 4.

T-mobile is band 4 which is 1700/2100 mhz. The Verizon s4 is not capable of 1700mhz. But if you are getting 4G it may be because your area is using 2100 mhz. I am specifically moving to iwireless and I was told they use the 1700 mhz band.

Many Verizon phones are sim unlocked, so it's most likely unlocked as well

Yes, I think all Verizon LTE capable phones are unlocked.
The I545 (Verizon S4) can receive LTE on band 4. T-Mobile serves LTE on band 4. The coincidence works well.

My RAZR MAXX HD definitely wasn't SIM unlocked... For the life of me I couldn't get it to work when I moved to ATT from Verizon... Not even GSM would work.

I just need to get some clarification from you guys. Are your VZW phones bought in the US and being in the US on t-mobile's or iwireless's 4g network. Because after I made the first post I went to the phone unlocking place in my local mall and talked to there techs, they said that the VZW S4 will not get 4g. I have also been doing extensive searches online and keep finding half saying it will work and half saying it won't. I have a feeling that the ones that work are working outside of the US as I found posts saying as such.
I read some where that the razr you had to flash the radio FW to get GSM to work properly.

I got my vzw S4 off craigslist but 99% sure it was purchased in the USA. I'm on T-Mobile's $50/mo plan.
Verizon's LTE phones are sim unlocked due to an agreement with the FCC when vzw purchased some bandwidth.
I think there was an update around 03/2014 that enabled band 4 on the I545. Then had to make some apn changes and tell the modem to use gsm/lte on band 4.
The one quirk I have is it will say "no service" after a reboot and until I make or receive a voice call. Then I get the "T-Mobile" instead of "no service" and things work as they should.

I'll have to go to iwireless and have one of the tech put a SIM card in my s4 and razr to give it a try.
The only options I have for the network mode on my s4 is
Global, LTE/CDMA, and GSM/UMTS. Can you post you settings?

I was just at iwireless today and tested my phone with their network and was unable to get it to work. iwireless is a t-mobile affiliate but they do not use 4G LTE in my area. Their system runs on a 3.8G 1700MHz which the VZW S4 does not have. I am told that they will be starting to switch all the 2G radios in the area to 4G LTE later this year, which should work with my VZW S4. So I am just going to have to wait till the end of the year and go back and test it again.

That phone was before VZW bought the band 4 spectrum and cut the deal with the FCC. All VZW LTE phones are SIM unlocked. Any AWS capable VZW phone is SIM unlocked and can use LTE on band 4. The S4 got it with an update last year.
I am probably going to do the $30 plan soon and plan to use my VZW S4. I am not going to port my number right away in case the service in my area sucks (doubtful, live in DFW in dense surburbia).

I went out off town this weekend and went to a t-mobile store and was able to get 4g service after adding the correct APN. But it is too bad that iwireless that is in my area does not use that band yet, they are staring to upgrade to that band later this year. Until then my s4 will only get edge service.

With the announcement of the T Mobile $100 2 line unlimited everything, I'm also interested in bringing my Verizon S4 MDK boot loader phone to T Mobile, but want to do my research first-- is it as simple as signing up for T Mobile and getting one of their SIMs and then-- would I be able to flash any of the ROMs in the S4 T Mobile Dev forum or is the T Mobile S4 a completely different device? Any caveats? Would I have to LokiDoki after the flash? Would I need to flash a T Mobile specific radio too (currently on i545vrufnk1)? Or is that all just overcomplicating things? Would i be able to just adjust the APNs on my current ROM after inserting a T Mobile SIM?

Quick reply to my post and for anyone else interested-- there's a post here that talks about using a 4.4.2 T-Mobile ROM by Fenny on the a Verizon S4: http://forum.xda-developers.com/showthread.php?p=57453019 I've tried it and LTE works great, MMS works properly, phone calls work as well. I'm on the Verizon i545vruamdk bootloader and Verizon i545vrufnk1 radio. The ROM is a T-Mobile m919uvufnb4 by Fenny.

Flash Verizon Firmware on AT&T Phone

I'm looking to bring an unlocked AT&T Note 5 over to use on VZ.
Is it possible to flash VZ firmware and have the phone work just as if it was a VZ to begin with (and receive 3g data, text, and calls) or is that something that's hardware related and flashing the new firmware won't help?
I've found this information, so I know the consequences of using an AT&T phone on VZ normally...
"If you're hoping to use your unlocked AT&T phone on T-Mobile, you should have no problems. Both carriers run their networks on GSM technology, so once your phone is unlocked, just pop in your new T-Mobile SIM card and you'll be up and running. AT&T and T-Mobile both use Band 4 for their LTE service, so 4G LTE devices should be able to access the network without issue.
Although Verizon uses the CDMA standard and not GSM, you still may be able to use your AT&T 4G LTE device on Verizon's LTE network, as they both run on the same spectrum; so LTE data should, theoretically, work fine. However, it's unlikely that you will be able to make or receive calls and texts, or access data over Verizon's 3G service.
Sprint is also a CDMA carrier, but runs its LTE network on a different band of spectrum than T-Mobile, AT&T and Verizon; it may accept selected AT&T devices on its plans, but you'll need to check first."
I'm curious, because I rooted an flashed the unlocked software on a friends VZ's s7 for use on Republic wireless, so I know this sort of thing can be done. I'm just not knowledgeable about the differences in these 2 scenarios.
Thanks so much in advance!

You can't flash any firmware on the AT&T note 5 other than official AT&T note 5 firmware because the bootloader is locked. I'm not sure about the part of using this Note 5 on Verizon.

Why so hard to use with verizon?

I've tried reading a lot on multiple sites for a while now and see people saying you can put it on Verizon and other saying you can't. I've got the phone rooted and it's working on T-Mobile but I really want to put it on Verizon even if it loses some functionality maybe. Do I just need to flash s7 firmware now?

Verizon doesn't really use the same frequencies as they are a CDMA network and ATT/TMob is GSM.

This device is an AT&T exclusive so it was built to function on AT&T's bands and services. The phone, when unlocked is easy to use on T-Mobile, or any of AT&T or T-Mobile's MVNO's such as Cricket or Metro as both use the same 3G tech, T-Mobile uses the 2G tech AT&T used to use and both use bands 2,4 and 12 on 4G LTE. However, Verizon uses entirely different 2G and 3G technology based on CDMA compared with AT&T/T-Mobile's GSM. Verizon does use bands 2 and 4 on 4G LTE so this phone may, in theory, be able to connect to Verizon 4G LTE on those two bands. However much of Verizon's LTE service is on a low-frequency band numbered 13 that is not accessible by Galaxy S7 Active. I don't think Verizon will permit this phone to register on the network even on Bands 2 and 4.
