[Q] how-to question (nexus s) - Android Software/Hacking General [Developers Only]

Hey. I need to know if anyone knows how to do this.. I need some help.
When you subsidy unlock a phone or root an android, you can use a sim card from any service provider, not just the one it had been locked to.
I'll use t-mobile & AT&T for example: If I use my AT&T sim card in my t-mobile branded mytouch4g, AT&T's system cannot detect what kind of device I'm using.
I like that because AT&T's data plans for smartphones are extremely limited, with 5GB/month being the highest one. (also costs something like $50/month.)
BUT they have an unlimited data plan with no softcap for regular phones for $10/month!
I've been subscribed to it while using the mytouch4g for the last six months & used a t-mobile blackberry with it before that.
It's nice not having to worry about overages.. but as you probably know, t-mobile & AT&T use different 3g frequencies so even though my data is unlimited, it's locked to EDGE speeds.
Now finally, to the question!
I just bought a Samsung Google Nexus S for AT&T. How can I modify it so that it does NOT transmit it's IMEI or serial number or whatever it sends that lets AT&T know what kind of phone it is? I don't think just rooting will do it.
I was thinking.. Since there's a t-mobile version too, maybe there was something that could hide or rewrite its identity information. Or maybe someone knows how to manually edit it so that it can send a fake IMEI/serial/whatever.
It'd be cool to be able to use the Nexus so that I can stop waiting for EDGE lol

Can I use Touch Pro on verizon without data plan

Does anyone know if it is possible to use a Sprint Touch Pro on Verizon WITHOUT activating a data plan? I found directions on how to hack the phone to work on Verizon, but would just like to use Wifi instead of the $30 data plan. Thank you.

call verizon and ask if they will even add your meid to their database.
I talked to Verizon a while back and they insisted up and down that there was no way to add a smartphone manufactured after November 08 without a data plan. I didn't ask anything about phones from other providers so as not to arouse any suspicion.
Basically you just have to call in and see if you could trick them into activating the phone on their service. The IMEI gives the make and model of the phone away though, but perhaps they won't check.
That's a bit of a gamble to buy the phone not knowing if it will work. Going through a person instead of the site will probably get better results though! Hopefully someone here who has done this successfully will chime in

[Q] HTC Maps on MyTouch 4G?

So I want to use a navigation app on the MyTouch 4G without using any data. If I'm not mistaken, the Google Navigation app uses data to download the map of your current location. The new HTC Sense maps (again if I'm not mistaken) are saved on the phone and don't use data. So my question is if I can get the HTC maps on the MyTouch 4g (specifically without having to root the phone and flash the new Sense rom onto it)?
What's the point of using a mthd without data? Really just defeats the purpose of having this kinda phone if you ask me... Just my opinion though

^ What he said!
They build HSPA+.....
what you were sayin' ...? ))
But, srsly, I see were you coming from....I would rather store my maps on SD so it can be cached faster, especially for "out of 3G/4G range" towns
Its not that I don't want to use data with the phone, I do. Its just that I am considering switching to the cheaper limited data plans that T-Mobile will roll out in the near future. So thats why not using data for the nav would be great.

The "limited" data plan will only work with certain phones. The mt4g will be a premium device that will require the unlimited data plan.

Yeah but I'm using a G1, so I can just use that to get the new data plan, then I will buy the MyTouch 4G off-contract and swap the sim.

Tricky fellow! LOL! J/K
Sounds like a good idea.
If you're trying to avoid getting the unlimited plan by pretending you're still using your G1, it won't work. They have a database of all the IMEI #s and the IMEI of the phone you're using gets transmitted, so they can see what you're using.
Back on AT&T, I bought a used iPhone (original model) and spoofed the IMEI to avoid having to pay for the iPhone data plan. Not sure if you can do this on Android.
You can see what I'm talking about by going to your T-Mobile account online and somewhere it should say which phone you're using. If you switch to another T-Mobile phone, it'll change. Carriers only have the IMEI #s of the phones that are branded by them. So if you put your T-Mobile SIM in an AT&T or unlocked, unbranded phone, it wouldn't show that phone under your account.

All of the above is true... Sold phones for years at radioshack...
Well it doesn't matter anyway because the new data plans will be available for all phones. From the leaked(?) document: "T-Mobile will respond to our customers' needs by introducing a new low-cost $10/$15 200 MB Web feature that can be added to any device."

Not that it matters (see my previous post), but even when they detect someone switches phones, can they really just alter your data plan without asking your permission?
The way AT&T did it, they would send you an automated text first a number of times. Then they'd add it. If it's stated in the TOS then they can do it. See if you can call them up and find a nice rep who'll try and keep it for you though.

No -- they just disable access to Internet but still charge you for the plan.

Until tmo recognizes that you are on a mt4g...then they will require the correct plan. Not to mention what you proposed was at the very least dishonest

Just answer the question
Can someone just answer his question without requiring his motives?
There's other people with legitimate reasons to do the same. What if you are in an area that has bad data reception? What if you wanted to use navigation outside of the city?
There's been plenty of times that I couldn't use Navi because of poor reception.
Use the navigon app it is now downloadable from the market. Maps are stored on the phone.

Sprint to Tmobile

Ok, can someone help me. I want to switch to Tmobile because in my area Data is 10x faster with them. I have to bring my daughters as well. I'm an Android junky, they are not. My question is, will sprint I phone 4s work on tmobile? Tmo says I have to have sprint unlock them, then I can put Tmo sim in and we're good. Is that true? Will it work on Tmo 4g? And will Sprint unlock easily? Thanks. I'm just gonna wait on the ONE to switch mine, but my kids don't know the joy of Android

Don't think so
Sprint is on a PCS network and Tmobile uses GSM. They are totally different. You could bring an ATT IPhone to Tmoblie.
You should try to get your daughters away from those IPhones...
Good Luck
Yes, the 4S has a GSM SIM card that can be unlocked, but they're not still not going to want to let you use it on a domestic carrier - they will generally unlock for a customer in good standing for international use. Looking at some threads about people trying to get the Sprint 4S to work on T-Mobile it looks like way too much hassle requiring special equipment (at least at one point in time) and with poor results when it comes to function on T-Mobile's network. The phones also need to be jailbroken because Apple is cooperating with Sprint to not allow you to take the Sprint phone to another domestic carrier's network - this brings a whole new set of potential problems.
If you really want to try it, Google it and see what it would take on your part. Personally, I wouldn't want to do something like that with a kid's phone unless they were going to understand the process and be responsible and able to troubleshoot if things went wrong (same reason I wouldn't root a kid's phone for them without them understanding what's going on and the problems they might face and how to fix them).
Unless they're deeply invested in Apple's market, I'd sell the 4S's and get them N4's or S2's or something. This doesn't have to do with any personal dislike for iPhones - but for the fact that if you're going to go with T-Mobile their ability to get a signal and what kind of signal will depend on the local network and what work T-Mobile has done, even if you traded the Sprint models for factory unlocked ones. They may end up only ever getting 2g, they might have poor coverage due to lack of 1700MHz and more. And since they're your daughters I'd guess you want to make sure they can get a signal no matter where they are in case there's an emergency. I would explain things to them like adults - explain the reason you want to switch services and the impact on them if they choose to stay with an iPhone, show them how Android is really not all that different - teach them about making informed choices and to understand why they are making a certain choice.
Big THANKS that was the BEST Answer I could hope for

[Q] AT&T Data Plan Question

Hi all,
People on here have been a huge help about this phone so I wondered if any of you would know this.
I have an AT&T branded One X, it has been unlocked and is on a custom rom. I'm not using it as my main phone, and my gf's phone broke now. I wanted to loan her my One X, but I believe she is on the $10 unlimited data plan for "non-smart phones". If she uses the phone, will AT&T know that its a smart phone based on some code in the phone, and is there some setting I can change to avoid this? If its just by data usage, I really don't think she'll use very much cellular data.
Anyway if anyone has any insights it'd be great!

They will know. There's no way to hide it.
As a former AT&T emoloyee, they have a system that detects smart phones. Not only do they detect it, but they will automatically add the $30 plan. Of course they will warn you, but a lot of people ignore it. I would suggest not doing it. Also if coming from a dumb phone, you need to change sim cards anyways. If you don't plan on using the HTC for data, no need to use it. Trust me, it is the same for iPhone and BlackBerry.

The two responses both say this, but AT&T doesn't have magical powers. For a while I had a Nokia N97 Symbian phone that I would call a smart phone, but at the time was on a non smart phone plan. When I upgraded to an Android phone (and got the carrier discount) I upgraded to the smart phone data plan.
If they track the data usage and you only use a small amount of cellular data, then it shouldn't come up. If they track some other info (like the EIN and compare it against a list of AT&T branded phones, maybe?) then there should be something that could be done about this.
Anyone else have any insights?

They track it by what type of data you using. In AT&T systems, there are four kind: pta (LTE), phone (3g/hspa), broadband (tethering), and pdpwap1 (non smartphone). If the system mismatches of what type of phone and plan you should have, then it will go with the plan you are using. This doesn't mean you can have a smartphone then downgrade and lose your data plan. AT&T is too smart for that and they want their money.

They detect the imei when using the cellular network. Not just from data usage, they can detect while sending texts, while making calls, anything. The system may not catch it right away but they will catch it. And while I don't see at&t doing so, it would be within their right to backlog you and charge you.

The N97 is an unlocked phone and not AT&T branded. AT&T has all the IMEI numbers for the phones they sell (and can correlate it to phone model), but not for the ones they don't. Its easy for them to read the IMEI number, and therefore know the phone is a smartphone (since OP has an AT&T branded One X). Don't need "magical" powers for that.
Even for IMEI number they don't have a record of, they might still try to tag you as having a smartphone and change your plan (probably by inspecting the data, as already mentioned by another). Folks on here have reported having their plans changed when using various unbranded phones (Nexus line phones, are ones that I remember specifically). But this is far less consistent (as your experience attests).
But for the OP, he is screwed by the IMEI number, and will be caught almost instantly.

New GoPhone Account for Nexus 5 ?

So I'm leaving Verizon and want to go with prepaid for my new Nexus. ATT has the best coverage in my area and I like that GoPhone gives you un-throttled LTE speed. I have a brand new ATT sim card that I plan on activating, but I'm unsure about what IMEI to use. I have an old ATT Samsung Captivate that I can use the IMEI from, but if I use that will they setup my account without LTE? I've also heard that ATT does an IMEI scan every now and again and if they detect a device that isn't in their system it gets zapped and wont work any longer. Any truth to this? Maybe AIO is the better choice? Help!

From what I understand, the only thing they use the IMEI for is to determine a phone's capabilities. While using my N4, I went to their store, got an LTE capable phone, wrote down it's IMEI number, and called AT&T and told them that was my phone so they'd put me on an LTE plan.
But since the N5 is LTE ready, why wouldn't you give them the N5's IMEI?
I thought the IMEI had to be in ATT's system for it to work. The Nexus 5 is not officially supported by ATT.
The IMEI is just an identifier. It's mostly used to lock out stolen phones. As long as its not blacklisted you'll be able to use ATT's network. I've used plenty of other carriers phones on ATT and have never had an issue.

That's what I'm planning on doing. lol If you're really that unsure you could always call ATT to verify.
Att might not have the nexus imeis yet. I remember for the nexus 4, I had to give them an s3's info. If you already have LTE on your phone, no reason to change anything with the carrier.
