What exactly is the point of SIM Unlocking? - Touch Pro2 CDMA

I was just wondering what the point of doing this is? Like is it just so I could use like the Verizon CDMA network or what?
I have the Sprint Rhodium400 and its STOCK radio version is 2.32.00.WU, so I mean according to what I read this is unlocked.
anyway, I was just wondering what if any point doing the Security Unlock has for me?

the SIM unlock is to use it on US GSM networks such as ATT and TMobile, it doesnt allow it to work on other CDMA networks like Verizon

Oh ok, thanks for the heads up on that one.
Good looking out (I was wondering about that for the longest time)

If your radio says WU that means that you can use any GSM sim card (not CDMA) on any network w ur phone. Security unlock - HSPL will let you flash your phone with custom roms. You can find more info about HSPL by following thread by OLIPRO. Of course thank him for his work. Have fun flashing.
FYI... Do not flash your phone w CDMA roms.

This is not true. The stock radio in verizon roms has a wu but all sims are locked minus the stock vodaphone sim. The locked sim does not have to do with the radio on the verizon tp2.

first. he has sprint..
second. verizon doesnt have wu.. unless you flash it w one (stock is always wv)
i do give you credit cuz i did not know that wu may still be locked.
no hard feelings.
peace

The Sprint TP2 has no SIM lock in the system, but the radio ROM is lacking support for the US bands. So while the Sprint TP2 will accept any SIM it will not get a SIGNAL in North America unless you pay for the security unlock and apply a patched radio.
The Verizon TP2 HAS a SIM lock in the system, but the radio ROM has full support for the US bands. So if you just want to use a SIM card, then all you need to do is get an unlock code from Verizon.
Both version radios have support for Euro bands.
Default behaviour:
Sprint = Use any SIM you want, but only get a signal in Europe and Japan when in GSM mode.
Verizon = Can't use *any* SIM except Verizon until you unlock, but to unlock you can do it by requesting a free code from Verizon CS.

so u can use ur phone on a different network (phones with sim cards obviously)

Yes. Once unlocked, you can switch the phone to GSM mode and use any GSM SIM card.

I do have Sprint (The Rhodium400).
It has been HSPL Unlocked for about 6 or 7 weeks now, just was curious about the Radio unlocking stuff (as I have never messed around with it).
I have already run the gauntlet of the various Custom ROMs out there. All (well most of) them seemed to be very VERY well built, however none seemed to suit me to quite 100%, so I have been working on my own for about 3 weeks now give or take.
It is a slow going process (mainly due to working so much), but it is very fun and a learning experience none the less. Looking forward to the day it is finished (So that I can start on the next one, lol).

..also thought I read somewhere in CMONEX thread a recap saying if unlocking sprint radio/SIM you'd be able to use Verizon towers... (will look for post & put hyperlink here soon)
also, from ppc/cmonex sticky:
BIG NOTE: if you have the Sprint branded TP2, then after running this SIM/Sec Unlocker, you'll need to flash a patched sprint radio (in other thread) to finish the process.
... sprint is a Security (CID) unlocker, which needs unlocking first, then a "patched" (unlocked?) sprint radio also...
"Originally Posted by Syriel View Post
By default, the stock Sprint radio only has support for GSM 900/1800 (Euro bands) even though the hardware supports GSM 850/900/1800/1900. When you flash Oli's WU radio to the Sprint TP2 it re-enables support for GSM 850/1900 (NA bands).
The reason that Sprint disabled the (NA bands) is because the Sprint TP2 (unlike the VZW TP2) is SIM unlocked from the factory. The VZW TP2 ships with full band support, but it is SIM locked from the factory.
"
Guess I'd just make it simple: Sprint needs a band enabler - 850/1900 (security unlocker?) & then a radio that works on it... (patched WU)

So I have Sprint service on my TP2.. if I unlocked it would I be able to receive a call from either network or do I have to manually select one and swap back and forth?
I can understand having a default outgoing radio (choosing CDMA or GSM).. but it'd be more useful to have the ability to take make use of both lines..

you would have to switch back and forth
and of course have a SIM card from a GSM provider like ATT or T-Mobile

Changing the CDMA Radio

I just got off the phone with Telus and what they told me is that they are releasing ANOTHER TP2 on the GSM network and that I would have to buy another phone TP2 just to get onto the GSM network.
This being said, is there any way to modify the radio signal in my CDMA phone to read both CDMA and GSM, or atleast get more speed out of my phone for connectivity to the net?
*update
I just got off the phone with HTC and the lady I spoke with told me, that to change the radio frequency I just had to change the ROM. That being said IF, I put a Telus HSPA ROM on there the phone should be capable of working on the network. Now that being said. If this is possible would it not be possible to run on both networks, CDMA and HSPA, making the signal control software dependent, meaning I have CDMA controls for standard phone calls and HSPA for running the highspeed network?
Update in previous post.
Eazy, just HardSPL and security unlock your radio bro...Only then you can use the GSM networks in your country (I'm guessing it's US)
But you can only activate one at a time. Either GSM only or CDMA only..CMIIW..
Just my 2 cents
Actually it's Canada
Right but if I unlock the phone, and switch it back and forth on and off the networks, how would that affect my account, could I hide the fact i was doing this?

I have this phone on Telus...I got it unlocked and I put my work sim card in this phone and it's on rogers. I switch networks when necessary....If you get a Telus sim card you would be able to use it GSM.
You should be able to pick which network you use. I saw it in phone settings, I think.

TELUS does not provide GSM at all. They are CDMA and UMTS.
So does this mean its possible. If i have a CDMA Sprint HTC Touch pro 2. That i have the potential of using it on At&t in the US?? All i have to do is unlock it?? Any information would be greatly appreciated.. Thanks!!
And if one does unlock a radio on said Telus phone, can one use both radio frequencies, thus enabling both CDMA and HSPA frequencies?

So Telus new 3G network is not GSM? It does have drop down menu showing "Send SMS over" GMS and CDMA. GSM is selected by default.

TP2, Not using CDMA any more, flash to GSM

I don't know if it is ok or not for what I want to do. I currently have a Sprint Touch Pro 2, but I have no plan to use the CDMA network, so is there a GSM ROM I can flash to? Thanks.
Never flash a GSM specific anything to your CDMA device. To gain GSM access you'll need to HSPL unlock, SIM unlock then flash a new radio. Search or check the Rhodium CDMA stickies for more info and step by step instructions.

I have a Sprint TP2 (i live in London). I bought it just for the 3.5mm jack. The sprint CDMA phones (as far as I'm aware) are already GSM unlocked to make it easier for their customers to ROAM. Mine definitly was, I just inserted my Vodafone Sim Card and switched it GSM (All Settings/Phone) and hey presto it's all good.
But definitley do NOT flash a GSM ROM to this phone it may brick it. There are plenty of good CDMA ROMS about here and on PPCGeeks (which leans a little more to CDMA).
Cheers.
this is like the 4th thread about this from the op, hopefully it has sunk in that this can't be done.

Can You

i need to get an unlock code for the htc touch pro 2 if u give someone that has sprint your imei because i dont have sprint or a credit card to purchase it online

Make sure your Radio says xx.xxxxWU at the end.
Sprint phones are not unlocked for us carriers.

That's half true.
What Diamond_dawg says is 100% correct in respect to the SIM lock.
Sprint TP2 devices do NOT ship with a SIM lock. The phone will accept any SIM card without issue (even those of North American GSM carriers). There is no specific block on ATT/TMO SIM cards.
What Sprint does do is ship a gimped radio ROM on the devices. By default the Sprint radio has the NA GSM frequencies disabled, effectively making it a dual-band device. Or, comparing it to a computer, the "driver support" for 850/1900 simply isn't there.
You don't need to SIM unlock a Sprint TP2, they come that way by default. You do need to security unlock it however, so you can flash a radio ROM with full quad-band support.
Verizon phones are the opposite. They ship with a SIM lock, but have a quad-band radio ROM installed by default.
Interesting....

CM7 question on the radio unlocked

well hello my question is r simple, i want to know if the rom CM7's post with the radio unlocked i can use for the Droid Pro, but for the European version because here we use GSM / HSDPA
Changing ROM's does not affect the frequencies that the radio uses, nor does it render your phone unlocked for use overseas.

Positive. It is more evident in the united states since we deal with carriers and different frequencies and such. My T-mobile branded phone was rooted, running CM7. If I used an AT&T sim card, it would ask for an unlock code. I got my unlock code from HTC and with an AT&T sim I am only able to use 2G speeds due to different frequencies for 3G and 4G. You can change your radio, but not the frequencies that the radio utilizes.
One quick alibi though. There are some root methods, such as the G-free method, that can sim unlock your phone.

then I can put the rom, but my problem would be the frequencies used by radio stations? there is some method to this?
It is not so much an issue for you because companies overseas use the same frequencies...you just wouldnt be able to purchase a sprint, tmobile or verizon branded phone..

S6 Edge - G925R - US Cellular

I have a rooted S6 edge unlocked for US Cellular (G925R). I see a lot of ROMs here on XDA but moslty for other variants .
Is there a way to safely flash a ROM belonging to different version for the version that I have ? Is there a workaround that can accommodate this ?

I assume the G925R has an unlocked bootloader, which is how you got root.
You should be able to modify the updater-script in a ROM to allow it to flash properly on a G925R (zerolteusc), I guess a ROM for the T-Mobile S6 Edge could be edited to work on a US Cellular.
Don't try it without confirmation from a more experienced member though. I'm just saying, editing the build prop will work, but T-Mobile is a GSM based carrier whereas US Cellular is CDMA, so not sure if the ROMs for the G925T will work on your phone.

Thanks, I will look further. Pardon me if I am asking a silly question but I see an option to choose the preferred network mode as LTE/CDMA or LTE/GSM. Also my device has a SIM card slot so is this device capable of both CDMA and GSM ?Currently I am using a Tmobile SIM in it and I have also tried an AT&T SIM, both worked as I could make calls. I am asking this as I am planning to use this phone outside US and if the device is CDMA only it will not be able to work on the networks outside.

No problem.
Pop in a SIM Card of your choice and you can use the phone on most GSM based carriers even abroad.
You mentioned that AT&T and T-Mobile were working, so you're all set.
Verizon, US Cellular and Sprint devices are CDMA but they have a SIM slot. So they will work with GSM carriers provided they are unlocked.
Oh, and about the network mode, select the right one depending on your network. If you're on a CDMA network, choose LTE/CDMA or if you're on a GSM carrier, choose LTE/GSM.
