[RESOLVED] Using a HTC Touch Pro2 on AT&T GoPhone (prepaid) Network?

[smitty7002]

so i bought the AT&T LG Neon slider phone, that was gonna be used as a GoPhone meaning it's on a prepaid plan.

My dad has an extra HTC TouchPro 2 smartphone laying around, it says on the box "HTC Touch Pro 2, Global Smartphone". It was bought from verizon to be used on for his business phone, but it also says it's a global phone (meaning it can work with AT&T's GSM network instead of verizon's CDMA?)...it also has a cracked front screen but i was wondering if u could just replace it with this.

So i would need to unlock it somehow, and probably erase the company stuff off of it, it has this "iAnywhere Afaria" software as well. Then would i be able to insert my AT&T sim card out of my LG Neon into this HTC smartphone and be able to use it strictly for SMS + calling? i dont wanna waste my money on the data, but how would that work? would AT&T prepaid require me to keep a data plan or be able to disable my phone?

Im still not sure whether u can unlock the phone to be able to use the US GSM cuz i know it's global phone that can use non-GSM networks..

thanks A LOT for your help, i'd really like to make use of this phone laying around the house haha.

So I originally had only my old GoPhone, a LG Neon with a prepaid LOCKED sim card. It is important to know that if you bought a sim card and it came with a monetary bonus, such as $50 of free airtime, that you'll need to call AT&T GoPhone support (611 from ur AT&T phone or 1800-331-0500 from any landline) to "unlock" the SIM card otherwise it won't be recognized in any SIM device.

So for future reference here's an entire overview what I did

1. Originally an old Verizon HTC Touch Pro2 Smartphone that had been deactivated, I performed a hard-reset to make this phone start from scratch.
2. Once this was performed, obviously Verizon wanted me to activate this phone, I just ignored all of that, and preceded to install a variety of programs, tinker with settings and such.
3. Once I was ready, I went to the wonderful site made by Olipro and Cmonex, here.
4. I bought the software via Google checkout and received the download link for the EXE software that this site will send you. I paid a total of 11.50GPB (equivalent to US$18.03) for this software.
5. I unzipped the file, and ran the EXE. There are a total of three parts in this software that you must perform, to get your phone unlocked. STEP 1 - Flash Hard-SPL: "It will flash your device with a patched SPL. To do this, you MUST have activesync [aka Windows Mobile Device Center (WMDC)] synced with the PDA, failure to properly apply Hard-SPL will result in rest of steps failing." STEP 2 - Unlock Radio: "Your device will be flashed with a specially patched radio - this will allow the phone to be unlocked - AFTER this has completed (which is of course dependent on step 1, you are ready)." STEP 3 - Run Unlocker: "This will run the unlocker on your device...it's a nice little GUI program I made, so when it pushes it to your phone, do please pay attention."
6. So off we go...running this unlocker. Windows 7 x64 is confirmed to work so don't worry if you see a warning message.
7. Follow the instructions, you should install a CAB file to your phone. In my case, my phone had randomly shut off before the ROM installation for Hard-SPL began, so you need to eject battery, put it back in and turn it back on, making sure WMDC is connected.
8. Let the ROM flash, it should be pretty quick, took around 45sec for me as I had a fresh HTC (recently hard-reseted).
9. Confirmation of successful Hard-SPL should follow, now you flash the Radio firmware which should follow the similar procedure as STEP 1.
10. Once that's done, do STEP 3, which should be quick. A GUI program will pop up on your phone, select the first two options, and you can leave the CID key alone, then press continue and you should now have an unlocked phone!
11. In addition to this, I also ran this flash to update the radio firmware as I didn't realize the SIM problem till later. I don't know whether it makes a difference but it certainly doesn't cause harm so you might as well do it .
12. Insert the SIM card you had "unlocked" from the customer support at AT&T, or any unlocked carrier of your choice. Go to settings and set it to "GSM/UMTS Only" and Manual. Scan for your network, it should connect. Place an outgoing call, try incoming and send a few texts. All should work as is.
13. If you're worried about the Data Charge, just for a safe precaution, install NoData to toggle any data services off.
14. So...if you look at this thread and DON'T act like the n00b I was, you should be able to do this in like 15mins haha, not the various days I took by posting n00b question after one another.

IMPORTANT: To unlock your phone without external software via Verizon and avoid paying for the third-party software, you can call their customer service number 1(800)-711-8300, and follow the guide posted here. I'm not sure if you still would need to run Hard-SPL and upgrade the radio firmware, but Hard-SPL can be found here and the newest radio firmware is in step 11, here.

All I can say is...thanks PPC!
