If i unlock my phone, will T-MO charge me for it?

my dads house gets ZERO SERVICE but i am 99 percent sure that AT&T gets fair coverage there. i have tried to connect to AT&T's service but my sim card doesnt support it. i did some reasearch and have found that in order to register on AT&T's network, i need an unlocked sim card. only problem is, are there any charges that follow with doing that? and will T-MO just unlock it because i ask them too?

Just call them and tell them you are going out of the country and need an unlock code.

ok the reason i wanna unlock it is to
connect to at and t's service at my dads house because he doesnt get any service there. so if i unlock it, will i be able to connect to at and t's service for free?
yes i read the thread and searched so dont get mad if this is a normal/ noobish question.

If you currently have T-Mobile then you need an AT&T Sim card to place in your G1. When you boot it will come up saying Unregistered Sim and will ask for a SIM Unlock code. After you enter the code you will be able to use the AT&T Sim card in your G1. You will NOT have data unless you change the APN's. Contact AT&T for that information or search for AT&T APN information.
If you ask T-Mobile for the SIM unlock code they are likely going to ask you to clearify. There is a sim lock (which protects your text messages and contacts) and it is programmed in your sim card. Then there is the NETWORK lock (or subsidy code) which will allow your phone to be used on almost any network. You need the SUBSIDY lock. Not the sim unlock.
To qualify for the SUBSIDY code for T-Mobile contact them by calling the toll free number. Do not call them from the phone because they will need the IMEI.
1) You need to be on a non-prepaid plan for at least 90 days of active and uninterrupted service. If yes, go to 2.
2) Call T-Mobile Customer Care from landline and give them the IMEI of the G1.
3) If you give them a valid reason for having it unlocked then they will submit a request and you should get your subsidy unlock code in about 72 hours via e-mail. BTW... telling them you want it unlocked so that you can use a competitors service is probably not the best request.
4) Once you've aqcuired the subsidy code, boot up your G1 with the AT&T SIM inside and enter the code provided in your e-mail from T-Mobile.
5) Contact AT&T for the APN information or find it here on XDA (search).
6) Enter the APN information by:
On home screen press MENU
Go to SETTINGS
Go to WIRELESS CONTROLS
Go to MOBILE NETWORKS
Go to ACCESS POINT NAMES
Press MENU
Select NEW APN
Fill in the blanks
You will never have to enter the subsidy code for your G1 again (even after a wipe or flashing to another ROM.)
NOTE: If you can't get the code from T-Mobile there are services on the web that will unlock for a fee. These usually range about $20 or so. There is no cost from getting it from T-Mobile should you qualify. Good luck.

ok thank you all so much, but some final questions,
ok so i can just call at and t and tell them that i would be interested in getting my phone unlocked because at my dads house t mobile doesnt get service, but they do, and i want to connect to their service?
also should i just visit the closest at and t store to do this?
if i have an at and t sim in will my billing and account info stay they same? like my plan wont change and t mobile would still be my mobile network even thoughi have an at and t sim card?
and i know i am planning on telling them that i am going overseas for 2 weeks for a vacation. that seems to work with these dudes.

P.S.!
will AT&T want me to sign a contract with them if i ask for one of their sim cards??? i just thought of that. i dont want a contract with them! lol. will they (AT&T) charge me for when i use their sim card and network?

Is this a serious question? If you were AT&T would you let someone use your network for free?
You might be able to use a pay-as-you-go AT&T SIM card in an unlocked G1. Not 100% sure about it so don't quote me on that.

fml i wasnt thinking
i totally overlooked that fact. dang

unlocking the phone will allow you to use pre paid sims with att as well
and you might be able to get a month by month contract with them (not sure of their available plans) either way google should show you the way

Original question(s) seem to be solved.

[Q] Why isn’t sim card being recognized?

Hey all, I’m having problems with my sim card not working, my Captivate doesn’t recognize it at all. I got this captivate to hold on to from my older brother who is currently serving overseas (not possible for him to use phone) a few months ago. When I got it, I rooted it, sim unlocked it (I have t-mobile), and got to flash roms and have fun with it thanks to you good folks on these forums.
About 2 weeks ago, the speaker was issues that really bothered me(had to keep tapping it in to get It to work) so I decided to send it over to Samsung to fix. The phone was still under warranty, so it cost nothing to fix fortunately. I just got it back yesterday, and since then my t-mobile sim card would not work. I rooted, sim unlocked, and flashed many different roms and still not working. Its as if the phone thinks there is no sim card at all (“No SIM Card Emergency Calls Only”). I also tried this app called Samservmode, and enabled all bands (GSM/WCDMA) to see if it would work; it didn’t.
I was ready to call Samsung again, but when I went over to my friend’s house and tried his att sim card; it worked perfectly and I was able to send texts and make calls. So something must be wrong with my sim card, it works perfectly on my g1 though (my backup phone that was used while Captivate was away). I was able to use the same t-mobile sim for a few months in a row before I sent it to Samsung, isn’t this possible for me to do it again? Any advice on doing so would be much appreciated; thanks.
P.S. My t-mobile sim card is prepaid if that matters, so I don’t use 3g or edge or any data networks.
Also my current setup (if it even helps, I've been flashing between froyo and ginger nonstop trying to fix this issue)
Firmware: 2.2
Baseband: I897UCKB1
Kernel: 2.6.32.9
Phone number and network is unknown
Mobile network type: HSDPA
Service state: Out of service
Roaming: Not roaming
Mobile network state: Disconnected
Everything else works pretty fine on this phone (wifi, bluetooth, etc.)

UPDATE: I went back to my friend's place and with his att sim card in, I tried adding a t-mobile APN based on
http://forum.xda-developers.com/showthread.php?t=744535
Unfortunately this did not resolve the issue. I did this with his att sim card because when there is no sim (or in my case, my tmobile sim) in the phone, you can't access mobile networks in settings.
I am also currently on stock I897UCKH3

UPDATE 2: So I just tried my other friends t-mobile sim card (that is on a plan) and the captivate had service; was able to make calls and text. My prepaid sim card seems to be the culprit here. I don't understand because as I tested my friends sim card on the captivate, I also put my sim card in his iphone 3gs (unlocked) and it worked fine there. Is the captivate on strike against my sim card or something? I'm going to try calling t-mobile tomorrow (doubt they'll help since the captivate isn't their phone) and see if anything can be done. In the meantime if you guys have any advice, I'm all ears.

UPDATE 3 (This is getting kind of annoying): I just got off the phone with both Samsung and T-mobile and both of them don't know what to think. I'm beginning to think this is a special case and this problem only occurred to a very few amount of people. If anyone can help with suggestions I would be very grateful. I'm thinking about going to a t-mobile store today to see what they think, maybe seeing the issue in person would help in their perspective.

Doubt anyone is going to answer or even post, but here goes:
BUMP
I also went back to stock and followed this guide:

with no success.

You try getting a new sim card?

Does T-Mobile have any policy of replacing prepaid sim cards? If so, that sounds like your best option. Also, Samsung might have been angry at you cheating their system, and purposefully disabled your sim card. Make sure you take out your sim before sending it back for repair.

Thanks for the reply guys, much appreciated. I decided to just live with it and keep the captivate as a galaxy s wifi if you will for media purposes only like an ipod touch. My g1 will be a phone. Once the nexus prime comes out I will start up a contract and finally experience 4g speeds and w/e else I can get with a contract thats not available on prepaid.
Also I did not send Samsung the phone with the sim card in, idk how they must've known to block it. Thanks again.

[Q] Does HTC G1 work without a Data Plan?

basically i want to get a tmobile prepaid payasyougo plan with 1000 minutes for $100. i was looking for gsm phones and found the G1. i would like to know if i buy a new G1 on ebay for like $100 will i be able to just put the tmobile sim card inside and activate the phone? or do i need to get a tmobile sim card with a data plan on it? basically i want to know if i can use the G1 for just voice calls on a prepaid sim card. i also would like to know if i can use the wifi to connect to my router, or is that blocked unless i have a data plan? are any features in the G1 disabled if i put in a sim card without a data plan? i plan on using the G1 for only voice calls and browsing the web on my home wifi. can this be done on this phone? thanks for your help in advance

There ya go
Btw, I wouldn't pay 100 for a G1. I got mine for 15 bucks used.

if your g1 isnt rooted than no, the stock g1 wont let you sign in without a plan unless you borrow someone's sim card set it up and then change out sims, what you want to do is get one, root it (probably need someones card to do this) flash a rom (many are far better then stock) and when it comes time to sign in it wont madder what tmobile sim car you have in there. and if you unlock the phone you can put in just about any sim card (rooting will not unlock the phone) good luck! oh by the way if you cant borrow a card, try to buy one that is allready rooted for you, if you check ebay you'll be sure to find one, hell i sell some on ebay that are ready to go. oh and yes you can use wifi.

I got a G1 from stock no sim to cm6 working fully...all without sim
The thing I posted above does NOT need root...
You may have to downgrade, but that doesn't need root...
Try the following...on the emergency dialer type <enter>reboot<enter>
If it reboots congrats, the wifi thing will work
If not, you need to downgrade....but don't worry its not too hard
I can help you through it most likely

Straight Talk And Sprint Cluster F HTc One $ S3

So i wanted to do the BYOP with straight talk.. Went to the store got a BYOP Kit $59 and another 1 month $45 Card. Then (after checkin straight talk's MEID check on there site) Checked the MEID of the Samsung S3.. Went thru the activation process and it went thru fine.. Phone Didnt work. It was stock no root ect. Well... I suspected maybe there was a lost/stolen or past due so i called sprint and after 4 attempts and some social engineering that SWIM is not and is proud of was able to determine there is 249 balance and they wont release the phone .. The guy lied to me and said it was deavticated and free and clear. Great.
So yesterday I find a HTC one with a cracked screen but still works.. Great. I run the MEID thru straight talk and Sprint and its good and clear.. Awesome no past due's everything is ok.
Get home tried using the Tmobile Micro Sim and completed the activation process and it goes thru ok! (Dont you love how they make ya feel warm n fuzzy..) I go into the setting on the HTC one and change the mobile data between 4g lte Cdma to gsm and then do the root and sim unlock running viper and get the hidden menu and via *#*#4636#*#* and change the settings to WCDMA GSM ONLY Gsm Auto Prl.. And nothing..
Then spent 2 hours on the phone with Straight talk, got them to cancle out the Tmobile sim and Activated a Att Mirco Sim (They Said it would be better coverage ect) And still Notta.. I got a Htc One 32gb Boot Loader Unlocked (Presumably SIM Unlock) and Rooted and Would really like to get it working on Straigh talk.. I have seen a couple of people on here that have accomplised this But cant get a response from them how they did it.
I really need a working phone cause of the kids, ect. Does anyone have any ideas?
I also have seen how some of these knock off MVNO's say that a past due bal isnt a issue and they can flash a Sprint phone No Issue.. But seems like the S3 wont work unless someone knows of a sure fire place that can do it.
Or getting my HTC ONE to work on a Sprint MVNO but im assuming they will want a UICC# or Sprint 4g Mico Sim card number. And I dont know how to get one of those or who might have them.
Any one have any solutions how i can accomplish getting a working Phone preferably with 4g.. Id even trade these damn things out at this point. I would most likely like to get that HTC One on Sprint thats been unlocked to work with straight talk using its International Capabilities and the ATT Micro Sim that is now active and registered because i have 3 months paid thru them.. Any ideas?

[Q] Swapping ROMS on Straight Talk

I just got straight talk working on my ATT Note 3. (SMS, MMS, data, calls inbound and outbound working) But I heard that the SIM card is locked to that phone forever. And I heard that flashing a new ROM will make it where the card won't activate on the new ROM. Then i would have to spend the money and buy a new card Is this true? or is this with the IMEI only? also I can't seem to check my data usage on Straight Talk. When I text 611611 "usage" it force closes the phone. I'm thinking it could be the ROM so that's why I was discussing about how safe it is to swap ROMS on straight talk and if they can be re-activated after a ROM flash.

the regional unlock thread has the side affect of unlocking the sim as well"you wont need this except if you want to travel international ". And changing the rom has no affect on your already activated sim you just have to re-enter the apn settings into the new rom. And your sim chip is portable from one at&t phone to another as long as it will fit in the phones sim chip slot. So no you wont need a new sim card if you change roms. I really wouldn't advise you to change roms tho. If you don't know what you're doing you could brick your phone.
