CDMA to GSM , sprint to tmobile problems - Nexus 5 Q&A, Help & Troubleshooting

Trying to switch from CDMA to GSM, sprint to tmobile and tried 2 ways that haven't worked. 1st way involved selecting preferred network to global ,swapping out SIM cards ,selecting APN . The 2nd way was dialing *#*#72786#*#*, swapping SIM cards, while phone is restarting select APN, restart.
Our phone came with a free 1 yr service from FreedomPop. I'm suppose to be able to cancel service at any time.
I also took the phone to a wireless repair store and they told me the phone can't be switched to GSM. I've read that it can. HELP!!!
The main problem is that the phone can't send texts or call out. It can receive calls and texts.

GSM Settings While in Ireland

I have a Verizon TP2 and have unlocked the SIM. I'm heading for Ireland next week and have purchased a prepaid GSM SIM for use in Ireland. Do I need to reset any of the Phone Settings on my TP2 or will it automatically make the changes when I insert the SIM and turn it on in Ireland. Thanks.

i am using sprint TP2, easy switch to GSM network, just go to setting/connection management/phone setting/network
choose GSM ONLY, then system will search GSM network automatically
remember insert GSM SIM card in the phone first
You will have to get data connection setting for the prepaid provider if you want to use your data connection

That is what happend to me with my VZW TP2 in Greece.
Switching to GSM only worked for the phone but I need settings for SMS and Data.
Got the settings but VZW put some kind of lock on the connections settings app. My settings would always revert back to the vzw settings and I would always get connection failur pop up.
Got back home and found online some details about "CMGaurdian"
This program either locks the conection manager or imediately reverts changes back to stock. I think you may need to disable this in registry to enable data and out going sms reliably.

[Q] US GSM Carrier Unlocked Sprint Touch Pro 2 - Data Issue

I unlocked my Sprint Touch Pro 2 and I am using an AT&T SIM card here in the United States successfully.
The first few times I used GSM mode, a menu would pop up and ask me which network settings I wanted to use (AT&T or T-Mobile).
Now, that menu is no longer popping up. So, I am unable to select the settings for AT&T. Data is now not working on GSM (the phone tries to dial #777 as if it is connected to Sprint).
How can I get that dialog box to pop back up and prompt me to pick the carrier settings? I'm assuming that is what will fix it.
Thanks for the help.
well, I got it working by manually defining the following parameters in a new gprs network connection:
Access Point Name wap.cingular
Username [email protected]
Password CINGULAR1
it works, but then when I go back to CDMA on Sprint, it tries to use this connection.
Is there an autoconfig program that I don't know about? It popped up on my screen when I first started switching between CDMA and GSM, but it hasn't come up again.....
How do I enable "auto-switching?" More importantly, why won't it just get this info from the AT&T SIM card? Why do I have to enter it for it to work now, when I didn't have to a few days ago?
Do you mind share the information how you unlocked your sprint pro2 (CDMA I assume)? I have same phone and want to use it in GSM oversea. Sprint customer Service told me it is not a global phone. can't unlock.
thanks in advance!

[Q] D2G was unlocked by turbosim. but it have problems..

Hello.
I bought D2G from ebay last month.
It was locked and has bad ESN.
And I unlocked D2G using turbo sim card from ebay.
That item number is 200539432676 and you can search it just type "no cut unlock sim card".
And maybe you can unlock it follow these steps.
0. You need prepare local carrier's sim card, another local phone, D2G
1. Put your sim card in local cellphone and turn on. After it receive signal, pull out the battery and your sim card. (Do not turn off the cellphone before pull out the batt. and sim)
2. Put your sim card on locked D2G with turbosim.
3. Turn on D2G and change the network mode (if you need) and set up the APN
4. Check the data roaming
Settings - Wireless & networks - Data manager - Data delivery - Data roaming
After that, My D2G work with roaming mode. I can use calling, text messaging and 3G internet service thru GSM/UMTS mode.
(I'm living in South Korea and local carrier provide wcdma hsdpa service.)
But my unlocked D2G have two problems.
1. When I use other local sims with turbosim, it's not work. I guess this turbosim
has compatible problem. (Maybe newer sim will not work.)
2. I only can receive incoming call and message(text and MMS) when my D2G was connected on "H"(Hsdpa). I cannot receive that things when signal turned to "3G".
I cannot use D2G for main phone.. Is there any way to connect HSDPA only? I tried to find some apps for do that, but there is no apps for it. If anyone know about the way, Please help me!
Thanks for read my post and please understand my poor english skill
TurboSIM is not the way to go. There are problems with incoming calls not going thru, losing service every now and then/etc
You should really try to unlock the phone by code. Have you tried online unlockers? You may be lucky your phone not to be from the locked down ones and to unlock with ease. Give it a try!

I already got code from Ebay seller, and it dose not work.
And now I'm in South Korea so turbosim is only one way unlock it.
And I guess I can use my D2G with turbosim if I can connect Hsdpa only.
Is there any way to do that?

[Q] Can't connect to network?

Hi I receive my idol3 today and I popped in my metropcs sim that I've been using for my S3. The phone recognizes the sim because it prompted me to choose an apn, but the phone remains in emergency calls only. I turned off, factory reset but the issue still occurs. Any help would be appreciated.
You may have to revise your APN settings for Metro PCS. Have you done a web search for the appropriate Metro PCS APN settings?

Yeah and it comes to the same as one of the options in the apn screen
it's weird it recognizes my number but for
Network: Unknown
Service State: Out of service/ Data: Out of service
Signal Strength: 0
wifi works and it reads my sd card.
Metro
Whenever you switch devices on Metro pcs you have to call customer service and have them swap the devices in their system. It's how most CDMA carriers do it and Metro used to be just CDMA before Tmobile. So your device isn't activated on the account the sim card is on. It's really weird for GSM based carriers and I do hope Metro will change their system.

Straight Talk LG Style 4 - Verizon sim / towers

So I bought the phone and a 35$ service card three days ago from Wal-Mart. Activated the phone around 3am that night. Phone hasnt worked once. No calling, texting or using data. Ive contacted ST CS numerous times with no help. Im told the same everytime. Dial *73 then turn off and back on, if that doesn't work repeat. Well it wont even let me dial * numbers. Pops up sim not registered, sim not provisioned, contact service provider. So whats what ive done. Yet they keep telling me my service and phone are active so they cant do anything. Ive seen a lot of people say to get an ATT sim and use that instead of the Verizon sim, and that will do the trick.
My phone number doesnt show up in settings. Network type doesnt. Cant edit or add or delete APN. PRL is blank in settings and no way to change it. Does anybody have any ideas or advice on what to do to fix all these issues???? I have 4 bars at all times but my service says 1x and yet i cant make calls or texts. Calls say im roaming and to buy a service card if I wanna make calls. Texts get stuck on sending then minutes later pop up they failed.

Are you certain that you activated the device correctly and entered the SIM card number correctly when you activated the device?
Give me an accurate and descriptive breakdown of the exact steps you took when you activated the device and SIM.
BTW, AT&T SIMs are for GSM devices, not CDMA devices, if your device is a Straight Talk device, your device is a CDMA device. I doubt an AT&T SIM will help.

I mean, I'm assuming I did everything right lol. I followed the steps the ST website took me thru. Phones brand new, never been activated. Brand new sim. I went to the website, chose activate, chose I have a ST phone, input my zip, input IMEI, input SIM #, input service pin, created my account, updated profile settings, restarted phone. The app says my service is active, the website says its active, ST CS says its active on their end. But I can't call or text or use data. My network type is 1xRTT. I have 4-5 bars at all times. When I try to call regular numbers, I get a "you are roaming, to place calls please purchase a service card" or something along those lines. When I try to call *73 like ST keeps telling me, it says sim not registered, sim not provisioned, contact service provider.
