Avoiding Data

Hello,
I'm currently on AT&T using a G1. The nice thing about my current situation is that I am not forced in any way to use a data plan. Without getting into it I do no need data at all. I was wondering what the best way would be to avoid data on this phone. My current plan is to get the t-mobile version of this phone and to unlock it since there is a lesser chance of AT&T having this IMEI in their database and edge won't automatically connect since the APNs wont be configured. Once AT&T detects a smartphone IMEI they automatically put you into a plan so my plan is to avoid this. I'm sure there has to be one other person who uses this phone on AT&T without being forced into data. Any tips?

Consensus over on the ATT forums seems to be that ATT can't read non-ATT branded IMEIs. There are folks that commented on running Nexus Ones, and other non-ATT smartphones, and ATT could not figure out what phone it was. One guy had the data plan added when he put his SIM in a Nexus One, and he called ATT, they said it registered as a Blackberry. He told them it was a dumb phone, and they took the data plan off. Its not guaranteed that you will be safe from getting a data plan added, but I'd say its a pretty safe bet.

You can avoid any problems by going into the Settings / Connections and deleting the Internet connections. If there is no connection setup, the device cannot make a data connection to the carrier.
EDIT: Sorry, I just noticed that you said G1. This is a TP2 forum, and I wasn't expecting that. I don't know how you stop a connection with a G1. With the TP 2 (or any WM 6 phone), the above should work. Just make sure that you delete the connection each time you hard reset or flash a ROM.

go in settings and remove your apn settings

Oops that was some poor writing. When I said "this phone" I meant the touch pro2. I think redpoint73 answered my question pretty well. Thanks all.

[Q] Can I use a t-mobile SG3 with AT&T?

So I'm planning on getting an unlocked SG3 but it's originally from t-mobile and I currently have AT&T. Will this work? I'm not planning on getting the expensive data plans though... But I heard that AT&T wouldn't be able to read the phone because it's not an AT&T phone.
Also I have a SIM card. Would I be able to go to AT&T and ask them to transfer my contact/info from my SIM to a microSIM free? Some people have said that they simply want to get a microSIM and said that they have an adapter to make it a regular SIM card so that they can still use it for their "dumbphone."
P.S. I don't know anything about networks or phone details since I'm not knowledgable about the hardware and whatnot about technology. So please keep the explanations as simple as possible. Step by step processes would be nice!

Yes you can fully use the T-Mobile version on att and get H+ speeds. Not sure about data plan... I know that worked for international version though.
Just store your contacts on your Google account and you can sync your contacts to any phone in a minute. No need to store by Sim. Yes there are microSIM adapters, but I don't like them as they sometimes mess up the prongs that read the SIM.
The only thing you won't get is lte speeds but h+ is more than sufficient.

I can confirm that as I am using a T-Mobile sg3 on at&t whilst typing this. The only problem I had was the mobile data wouldn't work at first and my local store changed one character of my imei and it started to work. There are other APN settings that work too.

Need Help Getting Sprint Network on Verizon Note 2

Okay, I'm sure the information is all out there, so before I get told to search forums or google, I have. My issue is that I'm just having the hardest time putting all the scattered information together and understanding it. There's too much information to decipher whats needed, accurate andd up to date for my situation. So I was wondering if someone whose done this before could just give me the straight to guide.
I have verizon, my girlfriend has sprint. She broke her S4. I have an old verizon note 2 that is unlocked, rooted, custom recovery and on CM11.
What I need to do is get it on the sprint network and get her service switched over to it.
I know it has something to do with APN settings, but there's so many different ones whether it's for internet and MMS. I basically just want her to be able to use it to make phone calls and maybe regular texts. I got all confused when I saw things dealing with PRL and what not, so I don't actually know which things I need to make this work.
I put the sim card from her S4 into my Verizon note 2 and opened the access point settings under mobile network. There are a bunch of sprint ones in there now, I don't know which one to choose. I tried the one just labeled "Sprint" and then rebooted to get the APN settings to switch over but I still have no service to try and activate the phone.
So could someone please give me a simplified walk-through of putting in sprint's settings on a verizon note 2. I tried flashing a Sprint CM11 rom but it failed. So now i am going to try flashing a sprint touchwiz rom to see if that will make all the necessary changes for me.
Update: I Just finished flashing jellybomb touchwiz rom, it flashed but wont get into the phone setup, says there's an encryption error and the phone needs to be reset. I did that and it still does the same.
Thanks in advance guys, I've flashed a lot of roms, I've just never switched my phone to another carrier before.

You can't activate a non Sprint branded phone on the Sprint network. Period. The esn is not in the Sprint database and even if you wanted to use the phone strictly for traveling internationally, The sim card from Sprint will not work in the Verizon phone for the same reason. You'd have to "clone" the phone/esn and that is completely illegal. I would spend my time on craigslist or Facebook and try to trade your Verizon phone for a Sprint one. That's what I would do.
FYI . Verizon phones are actually in demand due to the much larger customer base so making a trade for a Sprint S4 or Note 2 should be fairly easy. But MAKE SURE you check the ESN with Sprint before making a trade because a blacklisted esn phone can NOT be activated and you will be SOL.

So only networks like at&t and T-mobile will work on my Unlocked verizon phone?

If you're referring to your Verizon phone being a "world phone" which does in fact have a sim card and gsm network capabilities, then technically yes it would perhaps be possible to get it to work on AT&T or T-Mobile onl;y but it would be very difficult and time consuming to unlock the sim portion of the Verizon phone and hack it so that it would not be rejected by either network due to the ESN. You'd have better luck trying T-Mobile because they seem to be more lax with unbranded iPhones etc on their network. But in all honesty you would be better off trading your Verizon phone especially if it has a clear esn and getting a phone that's ready to go with no headaches and fully functional on the network.

thanks for the replies

SM-n910v 5.1.1 rooted - questiong about using it on att.

So I bought this phone the other day from a kid, and I saw it was pulling LTE with a Nano Sim from ATT - so I figured great, I threw in an Mirco SD card with unlimited data from ATT - it's only showing HSPA+ 6/4 up down which I can live with. I redid all the apn settings to make sure I'd be able to use it for text/calling etc. Reason I decided to get this phone was because I wanted to root it and then hotspot on it. I don't know why att has to be a douche bag about hot spotting. I'm okay if they gave some basic cap (even with the unlimited plan), but alias I am unable to get LTE speeds no matter how I goof around with the phones apn settings. I don't know how he got LTE speeds on the phone. However the LTE symbol popped up it wasn't rooted at the time.
Now next question: I have twrp installed and I've flashed/wiped/reset the crap out of this phone goofing around with some of the settings. Deleting all the Verizon stuff, but Now I'm kinda wondering if I am at a stand still. I understand after reading a bit that Verizon and ATT using different bands, so I understand I may be capped because of that. But I just can't wrap my mind around the fact that when he popped in that little sim card it showed LTE and It was in fact an ATT sim.
So now on to why I made this post - I'm wanting to flash an att 910a firmware to the phone. I understand it's risky - but if I have TWRP in stalled won't I be able to get myself out of a boot loop? OR will it render the phone unable to log into twrp? I've read people using the 910t firmware on a 910v phone. I know there is kernels bits and bytes that may render the phone useless? I'm hoping by flashing the ATT firmware on there it'll allow me to get LTE speeds.
Also, when flashing the 910a is there a kernel that's preferred?

So... Google FTW - I now Have realized after reading that ATT has very ignorant customer server reps. After posting this I was thinking I wonder if that KID got LTE because he had a nano sim or because he has an IMEI that is LTE compatiable that is registered to ATT... So I decided to pull my sim out of my note 5 make it touch all the contacts in the sim card slot and booted the phone. Registered as 4g (not hspa+) and ran a speed test and I got 55/15 not to mention it instantly connected to the att network. So I need to call att and give them either the imei to this phone or give them a dummy one. Cause it is obviously compatiable enough to get LTE type speeds... But not with the new sim card they gave me (bit of info: I had a samsung tab a tablet with unlimited data and didn't know the sim isn't swappable to phones, so I had to have a new sim programmed in it's place so I could use phone/text etc with the note 4 910v).
You know sometimes when you're talking to a rep that doesn't understand technology.

Are Verizon phones unlocked? New SIM not recognized.

I have been under the impression for a long time that Verizon phones are unlocked, and had a tech tell me this - contracts stay in effect, but phones are free to come and go. So I took my N7 (for which I pd full retail, no contract) to a prepaid carrier and was able to use it with their SIM for a couple of weeks. It took help from a tech to configure the APN settings, but things worked fine. I did get a constant message in the status bar: not a Verizon SIM. Today the phone will not work, even though it shows many 4G bars, and says: No SIM or SIM not recognized. This message pops up every time I try to dial. I called the prepaid carrier and they said they are sure that Verizon has locked the phone and I should call them to unlock it. (Right!)
I don't know if it's a coincidence, but this happened right after I ordered a cell extender which requires the purchase of its own SIM. At first I thought there must be some confusion involved with this, but tech said he was sure it was a Verizon lock. Any ideas or information? Thanks!

Yes, the Verizon N7 is carrier unlocked; however, this isn't necessarily a prerequisite to using a pre-paid carrier's service if they're already using the same CDMA frequencies (in which case, their most likely just "leasing" their service from Verizon and reselling it as their own - these companies are called MVNO's (Mobile Virtual Network Operators) and there are plenty of them out there).
What I think is most likely happening is that Verizon is temporarily deactivating your SIM card, as if it were a Verizon SIM, due to the fact that you're still using the Verizon Note7 firmware. You have a couple options here:
If you have another phone, and another SIM card, you can do like the rest of us are doing and reactivate the other phone with the other SIM and then pop it into your N7. This will restore service to your Note7 and release the "hold" on the previous SIM, so that you can repeat the process with that card next time Verizon does one of their sweeps (appears to be a weekly event). A pain in the ass? Yes. But, after doing this a few times, I've gotten the process down to about 5 minutes. I just need to make sure I have my spare phone (a Verizon Note 4) nearby wherever I am.
Because the N7 is carrier unlocked and is capable of operating on either CDMA networks (Verizon & Sprint) or GSM networks (T-Mobile & AT&T), you can flash another carrier's firmware (like T-Mobile) and use their pre-paid service, or the pre-paid service of a MVNO that operates on GSM (like Simple Mobile). I use T-Mobile as an example because I know that they are not... yet... disabling SIM Cards (temporary or otherwise), but I can't say, with certainty, that the other two are not either. I do know that all of them have pushed firmware updates to permanently disable the ability to charge the Note7, so, if you go this route, you want to make sure you flash the firmware released circa mid-late October and then do whatever is necessary to block all subsequent updates.
Hope this helps,
Matt

Thanks. It does help and that makes sense. What was odd was that I was still able to access internet (not wi-fi, but network showing 4 bars 4G). I got a new SIM today and when I popped it in, same thing. Are you saying I would have to activate the SIM on a second phone (currently N5 still with Verizon while I prepare to leave them) before putting it back in the N7? Just keep switching SIMs back and forth?

It's kind of a crappy solution, and one that I doubt will continue to work forever (or, at least until the N8 is released)... but yeah. That seems to be the only work aground right now.

Yes, and it's a whole crappy situation. I can accept the recall, but not the hotlining by Verizon. I have learned from this I will never buy a phone from a carrier again. Should have bought non-carrier specific directly from Samsung.
