one x on go phone plan?

im in a werid situation. the only phone i want is the htc one x. my plan expires the 26th of this month and i dont know what to do the phone comes out may 6th. heres the deal my dad is making me pay my line by myself so he will give the original family plan line to my little brother. so with his upgrade i intend to buy the one x and use the 50$ unlimited plan from their go phone options
will everything work ? the guy told me data wont work on 4g phones. and will a go phone sim even work on a smart phone ? i really want all this to work out because i need a nice screen and camera but do not want a contract. what other options should i look at because even atnt contracts minimum is close to 80 bucks !

are you talking about using an international one x? i decided on a prepaid plan and it works - but i bought an at&t branded micro-sim card from amazon. others are cutting down at&t sim cards. some are transferring micro-sims from unlocked iphones. there are people posting on the boards that the $50/month plan works for them - you just have to be careful about not drawing attention to yourself by your data usage. i am a minimal user so i went for the $2/day when used only plan (i am on personal wi-fi most of the time) and bought a data package.
you should also be aware that carriers like straight talk and net10 are offering $45-$50/month unlimited plans with purchase of their micro-sim cards. you can find out which network they run off in your area - they all use the towers of the larger phone companies.
check out some of the threads in the general forum as well as this one mentioning at&t. may help you. just be aware that having an international htc could mean no access to certain apps. it seems, for example, that google wallet will install but not open (at this time) on an unrooted international one x. could be a function of at&t, but i think it's google. found a way around that for google voice, but not for wallet. don't know if google wallet will install and open on an unrooted phone.

thanks for all the info. i was able to see h20 works in my area. im not buying the international version this is straight up the may 6th atnt released version. thats why im curious how am i going to keep the same number yet somehow use call sms and minimal data. i too am on wifi a lot but i def need 3g for work and gps. im just worried about getting a micro sim card and im hearing a lot of people getting cut off data on atnt once they found out their using a smart phone
also sucks to be buying an lte phone and no lte available lol
would this work ? what kind of speeds are on it
http://www.shopstraighttalk.com/bpd...ction=view&productVariantExtensionId=13837291

there are a couple of people on these boards who are longtime at&t users and know far more about the ins and outs. you might try searching them out in the at&t-related threads in the one lx forum, since you are planning to buy, i gather, an at&t phone. better to know ahead of time what you can and can't do. it may still be worth your while to check out straight talk and net10, however, since the last i looked they were advertising programs for at&t gsm phones that claim to be unlimited for $50/month. no lte, obviously, but also possibly no hassle over a separate data package, though they are making it clear they will pull your account if you go over their "unlimited" limit.

alright i searched around a lot and straight talk does use atnt towers so that may be my best bet i just need someone to help me confirm that if i buy the atnt one x should i let them install a sim card in it ? will it even matter? as soon as i get home i would take that phone out and put in my prepaid one. does atnt prepaid not let u use data anymore for 4g phones? lol so confusing

check out howard forums re at&t prepaid and also straight talk. i got into at&t recently. apparently there have been some policy changes that i wouldn't have noticed since i am not a long time user. one of them applies to smartphone data usage limitations - as in, you have to buy a data package if on one. there are a couple of people on these boards claiming they are using data without a data package on their smartphones and it's a matter of not triggering usage limitations. i have no way of knowing and it's confusing to me, too, so i'm just sticking with what i have till i run into a wall, then i may jump to net10 or straight talk also.

[Q] GoPhone... Will a Glide work?

It seems that the Glide is only an AT&T-branded phone. Has anyone used one with GoPhone? Thought about picking up an unlocked one on eBay but I don't want to encounter the same "Invalid SIM card" issue I encounter when I put my GoPhone SIM card into my unlocked AT&T-sourced Skyrocket. Thanks for any info!

I can't say for certain, but I don't see why not. I use my phone with the T-Mobile monthly 4g plan and everything works fine. I do however, only have an EDGE/2g speed data wise due to the frequencies, but the phone was designed for AT&T so that wouldn't be a problem for you.

Appreciate the reply, narume. I think that the issue arises from this:
trinikartel said:
Let me know if you ever get that working.
What i THINK is that any phone that comes out of AT&T's clutches are in their system (both imei and with carrier iq) so once it you pop a sim into it and the information is matched to a device in their system they know what can and can't be allowed for the device. With international devices they don't have those IMEIs (which is why they always want the imei from you so they can match it in their system)
Your note is international...they can't "match or track it" so to their system it's just another random dumb phone
Your skyrocket is a known LTE/HSPA+ device to the system so it says no cheap data for you

So...assuming that this reasoning is correct, if AT&T knows that it's their phone they will have blocked its IMEI from being able to access data through GoPhone. And I would need 3G access in order to use it on my MicroCell. Anybody...?

Any at&t phones will work on go phone, and you can use a microcell as well, your phone still uses the 3/4G signal to connect for calls and texts. Also to get data to work for pictures, and mms you just need to call them and they will send you the apns, my nephew in law has an atrix 2 on a microcell with pic messaging working great. They also have a solstice 2 (dump phone) on the microcell, both go phones.

If you're getting Invalid SIM, you may have a locked SIM card, something AT&T started doing with their prepaid a while back. New prepaid accounts have the SIM locked to the phone it was purchased with for ~3 months, after that I believe you have to either call or visit a store to have the lock removed.
Other than that, there's no reason it shouldn't work, but do remember that AT&T will see it as a smartphone. This means with their new prepaid plans, if you're using the 10 cents a minute plan you'll be unable to use data at all. If you're using one of the flat amounts per month, like the $25 or $50 plans, you'll need to purchase a data package (even though the $50 is SUPPOSED to include unlimited internet, smartphones aren't eligible).
I previously used a Motorola Flipside on AT&T's prepaid, before this change I was using the 10 cents a minute plan, with 1000 texts a month and buying a 500mb data package, then rolling over unused data each month with the 10mb package, and everything worked the same as if I was on postpaid - text, mms, internet, etc.

Thanks all! I'm 1½ months into my prepaid service. I'll check with AT&T after 3 months have passed and see if they can remove the SIM lock.

You might go ahead and call customer service anyway, who knows, you may get lucky. 3 months was what a rep told my friend a year or so ago, but that may have changed or may not have been the rule at all. Alternatively, you can go into a local store and purchase a new sim (or purchase one on ebay) and have them transfer your account over to it, just make sure they give you a regular sim and not a go-phone sim.
I just tested my captivate glide with the sim I was using in my flipside. It seems to read the sim just fine, though obviously I'm not still a prepaid customer so I can't make any real calls with it. I've also used it on a T-Mobile MyTouch 3G that was unlocked, briefly, when I was working on the flipside. Once you have the sim lock removed I expect you'll have no problems using it in any unlocked or AT&T locked phone.

If you use the 50 dollar plan and use the wap.cingular apn it will use data just set that up before you put in your sim, and do call they should unlock it for you, if not tell them you will be going to straight Talk at&t phones work locked on them since it's a part of at&t just ran by walmart.

I have two Glides that I activated in June. NEITHER WAS SIM-LOCKED, ever.
Both are the newer 4G SIM, not the older one that says 3G on it. Got em from eBay for about $2.75 each. Both were activated online, about 3 weeks apart.
The first one, I activated with an IMEI of a Glide that broke and was able to use the SIM on a different Glide and other phones, even the Pantech Burst and got 4G. I activated it as 10c plan, then moved it to the $50 unlimited.
The second one was activated with 0000... generic IMEI with the 10c plan, and just like the first one, I was able to use the SIM on any GSM phone I have in the house (and that's quite a few).
APN: wap.cingular - only the name is needed, no userid, etc.

Sprint GS3 to Ting?

I just found out this network provider named Ting, that works on the Sprint network but prepaid (way less money), they have the exact same phones as Sprint, does anyone knows how to activate a Sprint device (SG3) to Ting?
Thanks.

Ting just announced a BYOD beta yesterday, but the SGS3 isn't supported officially. Check their blog for details.
If you're feeling adventurous, keep an eye on Ting's forums, since people are always looking for better ways to bring SGS3s over, even without official support (Ting is awesome about letting users do stuff like this). There are already a few methods that mostly work, but hopefully the BYOD program will make porting phones easier and cheaper (no donor phone, no pricey software).

I'm on these Sprint S3 forums because the S3 phone that I got from Ting is totally Sprint branded. So, it just doesn't make since why the S3 isn't on the porting list, along with the Ting newly announced Note II. Bummer.
However, you will enoy paying for what you actually use on Ting. My Sprint bill was $82 per month, but my last Ting bill was just $17 for using the same Sprint service the same way I always use my phone. So, I haven't change how I use my phone, and I get to pocket $65 per month. It's like I'm back on the old Sprint Premier plan since my monthly savings pays for a phone upgrade every eight months or so.

thats my point, I am paying ~90 dollars a month for plan that I barely use, my reception is awful and the data plan is worst. so I cannot flash this phone to att or t-mobile (those work better on my area), Ting will be the best possible solution, paying 30-40 dollars for what I am actually getting right now.

I also love Ting. I used to pay $225 for a family plan. I now pay ~$80 for the same thing. 4 phones all sharing the account. Can't beat that price with a stick!
I have figured out how to fix MMS on CM10 for Ting.
1. Use Voice Dailer and say "Edit APN's" apns is a single word. Or use Nova Launcher and create a shortcut to edit APN's. To do that hold down on an empty spot on a homescreen. Then choose "shortcuts", then activities, scroll to settings, choose APNs. That will give you an Icon that goes directly to edit the APNs settings.
2. Click on the icon you created and look at the APN2 settings. Click on each and find the item MMSC. Change the server to be http://mms.plspictures.com
and press OK, then click the menu hard key on the phone and select save. Do this for both APN2 items.
3. Reboot and your MMS should work fine.
I have not figured out how to edit the string for LTE data yet but I am working on it.

Ouch. just ran myself on TING. $119.50 for my average month (currently paying $35) I guess I use too much data even just the MINUTES would be $46 a month (I guessed 1500 since you don't get N&W from what I see on ting)
I currently with with 500 anytime minutes BUT that includes 7-7 N&W as well as any mobile mobile to mobile. so I only really use 200-300 minutes a month that are not mobile or 7-7 N&W
so when you figure out if ting works for you or not BE SURE to account for this very critical difference.

Fixed 4G!
Ok, if you have a SGS3 and you port it over to Ting it is very easy to get it running right.
If you are running a TW based ROM then you simply update PRL and profile and it will pick up the correct settings.
If you are running a CM10 based rom there is an extra step. In the attached file (apns-conf.zip) there is a file named apns-conf.zml
Extract it to you phone somewhere easy to get to. (I put it in the root of the CD Card). Then go into the phone and use any file util that allows root operations and move that file to /system/etc/apns-conf.xml overwriting the file that exists with that name.
Reboot the phone and you are good to go. 4G LTE will now work.
By way of explanation I flashed a TW rom, used an app to extract the APN settings. Then changed the default APN settings in the file attached so that CM10 would have the same APN settings as the TW rom and it worked.

Noob forever

All this is amazing, I'm trying to get my family on Ting, and my mom has a Sprint Gnex. I've looked everywhere, read the via programming thread, but you managed to get 4g working on a Sprint Galaxy SIII on Ting?! I assume you also used a donor phone and dragon magic?
You would be my forever hero if you pointed me in the direction of what you did, and hopefully I can apply it to the Gnex.

Basically he just went to stock, saw what file was changed when he got 4G working (by updating profile and PRL) and pulled that file so you could replace it while on a CM rom

would this work for metropcs to ting? Or is this only a sprint thing?
I mean if i wanted to switch from metropcs to ting, how would i go about doing so? Get a ting SIM card and than edit the APN?

With ting. One phone with 500 mins and 10gbs of data (amount i use) would come out to $200+ wtf Lol

ting is utterly USELESS for mobile data users.
its really designed for those people who only use minutes and text and not very much who are massively overpaying with the unlimited and high minute and data plans most of us use.
for those people its fantastic and very cheap.
for us Boost is one of the best. you can get down to $35 to $40 a month for unlimited everything.

Indeed. Many smaller retail businesses here have an open network. I guess it's supposed to motivate customers or something. I'd imagine some ports are usually blocked, but I rarely need anything except 20-22 and 80 anyway.

wow around here EVERYTHING is locked up tight. its very rare to find an open access point anywhere.
xfinity is around a lot of places (I have comcast so I can access those) but its largely useless as only the web browser works. none of the apps or gmail or any push notifications of anything like that works (port restrictions??)
the rare time I see an open access point pop up its usually too far away to get a reliable connection too and don't have time to go walking around with the phone in the air to try and find it

Thanks i'm going to get a used S3 and use it on ting.

Looks like ill be cancelling Sprint n jumping to Ting, seems like its a really good deal. I pay $80 a month for 450 minutes which I used about 15 minutes of, unlimited texts which I sent about 4000 last month n my data I rarely use now, bc I either use Wifi or my tablet. Sucks Ill have to pay the cancellation fee, but Ill be saving more in the long run.

before you cancel see about putting another handset on the account first and see if you can "sell" the account to someone else (for free) ie do a TOL a transfer of liability. someone else gets the account they may want or need and you don't have to pay termination.
how far are you into your contract? might be cheaper to "buy out" your contract and then terminate out of contract (not usually viable till near the end though)

[Q] current GoPhone user w/o smartphone plan wants GN2...

Sorry for the newbie-ish question, but I hope to get a solid answer before I make a purchase.
I'm running an Android phone on AT&T currently via a GoPhone sim. I don't have or use data, and I don't even care about it. All I use it for is voice/sms/wifi-data. But, I'm needing to replace the phone. What I'd like to do is get a Galaxy Note II, but *keep* the same GoPhone account setup...no data...no mms...just plain old voice/sms.
So, my two questions:
1) I've seen threads about persons trying to make it work with data and the proper apn, but has anyone had success using this just as a 'dumbphone' on their $0.10/minute cheap GoPhone plan?
2) Will I have to get another sim card (micro), and have AT&T transfer my account to it? Or, will I need to cut my current one (normal size) down? Will that work?
Thanks for your patience and expertise!!

Yes, I've tried GN2 as a GoPhone!
Okay, Koohiisan, let me see if I can answer your questions for you.

Sometimes you just have to buy something and try it out to be certain. I did that, and now I think I can answer your questions in a meaningful way.
You'll be pleased to know that yes, you can do this with 100% success! Like yourself, I had a GoPhone account and the GoPhone SIM to go with it. After receiving my Galaxy Note II, I pulled the SIM from my prior phone, cut it with a SIM cutter (normal -> micro) and put it in the Galaxy Note II. It booted up, detected the SIM, and connected to AT&T's network with zero issues! Calling and SMS works perfectly with no changes needed.
I did disable the APN using APNDroid, just so I wouldn't run afoul of AT&T's network since I, like yourself, didn't have data at all.
So, to answer: yes, you can take a GoPhone SIM, cut it (by hand or with a dedicated cutting tool), and install it in a Galaxy Note II and it will work with no issues! Hope this helps! ;D

800 dollar phone with no data,, seems like a sin ..lol jj

I know...it's tempting to add it...but I did the get phone for less than *half* that price, and I'm incredibly cheap.
My next plan is to try to enable the T-Mobile freqs and unlock it so that I can have a little more freedom about adding data down the road.

As I understand it, MMS (picture messaging) requires data. If you are running this same comfiguration I am (dumb-phone GoPhone SIM without data), then you won't be able to get MMS.

I thought the default GoPhone plans included mms?

I can't post a link to it due to my post count, but if you Google for "How to use an AT&T GoPhone data plan with a 4G Android or iPhone" you'll find the post from marathon studios that I just read on this subject. According to that site, it looks like the GoPhone data APN is actually 3G, and is different from the 4G AT&T APN. So without using APNdroid to change to the proper settings your phone would be pointed by default to the wrong APN.
According to that article, however, you still need to have a GoPhone data package on your plan. I'm on the cheapest $0.10/min plan and I can not add a data package to that plan...so like I said...if you are in my same situation you'll never be able to do it because you can't add the data. :/

LOL...I actually went and spoke to an AT&T customers when I had GoPhone. You CAN get MMS if you're on a phone that is 3G only. Any smartphone requires that you buy the data package to receive it.
Also, you'll have to forgo MMS or use a 3rd party Text Message like PINGER or such to receive MMS. However, if you're on a regular phone, you can only pay a few cents per kb download. this also apply to 3G with data package. I hope this help. Oh, and it doesn't work on iPhone 4/4s or any 4G phone.

FIX
Here are the actual screen captures of my apn settings on AT&T gophne with my Galaxy Note 2 SGH-I317 that allows me to send picture messages, I also took a pic of my cut sim card to show that it works, i tried it without wifi and it still works. It even goes in an out of 4g in the proper areas.

Using a free data sim from t-mobile for calls

I had a t-mobile 200 mb free data plan activated on a kindle hdx7 about a year ago. 2 months later I got an IpadAir2 and gave the kindle to my daughter and took out the t-mobile free data sim and she put in an att sim to use the data share family plan for $10. She is using most of the 20 gb bucket we have per month between her phone and tablet.
I activated a free sim from t-mobile for my ipad air2 and put the original free sim from the kindle on ice for a while. Tonite I found it and for the heck of it put it in the fire phone to see if the data plan would work in the phone. And it did! I chose the t-mo lte apn and rebooted the phone. And data started flowing. I was able to sign into Ooma mobile and make a successful call over data. The same with Time Warner's Phone2Go app. Was also able to make a successful call over data with this one. The only thing not working is using text messaging. It just won't work with the phone number assigned to the data sim Google voice worked too. Texting works thru google but mms does not work. The clarity of voice was best with Phone2Go, followed by Google, then Ooma. I heard well on all three, but was fuzzy and staticy to the receiver.
So if any of you have those free data sims from t-mo laying around, they will work on the fire phone for app calling. And anything else you want to use the data on.

[Disregard this post -- in post #3 I answer my own question]
Thanks, sashusmom. I tried this but I can't get it working. I can get to the TMO page where it tells me how much data I have remaining but when I try to browse anywhere else it takes me to the "upsell" URL to activate my device, get more data etc. I tried both unrooted and rooted and neither works. Another thought: I have a pre-paid TMO account that is tied to my unlimited 200MB SIM; is your unlimited TMO on a post-paid account, maybe?

I did some further research to see how this works and here is what I found:
Yes, you do need a post-paid T-Mobile account in order to have a SIM card that you can move from one device to another. Prepaid accounts with the 200 MB data plan, those SIM cards are married to the tablet they are activated on. Furthermore, if you do go the post-paid route in order to get this working, please note that you'll need a voice line on your post-paid account in order to get the 200 MB truly free; they give you a $10 bill credit every month as long as you have at least one voice line on the account. If you only have a data device, you will be charged $10 per month and you will not be eligible for the bill credit.

Furthermore, if you do go the post-paid route in order to get this working, please note that you'll need a voice line on your post-paid account in order to get the 200 MB truly free; they give you a $10 bill credit every month as long as you have at least one voice line on the account. If you only have a data device, you will be charged $10 per month and you will not be eligible for the bill credit.

Everything I wrote in the opening post is true for me. Please note that the apn needs to be T-Mobile US LTE/fast.t-mobile.com I just checked and data is still flowing. It is a prepaid data sim also.
Thanks for your research, but apparently it doesn't apply to me. I don't have a post paid account. That sim that was initially activated on my kindle fire hdx7 for the free data for tablets with 200mb and is working on my fire phone- I know it is the same sim cause I marked it with an F designating free. So it is not married to the tablet. It is working on my firephone. It is a data only sim so voice and texting does not work.
Also it probably does not work in a tmobile device. My kindle was not a tmobile device and initially was not even officially supported for the free data for life plan. But it worked. The firephone is also not a tmobile device.
Another thought for you Dustbinge- does your free data sim- 200 mb for life- have any of the 200mb left on it? If not it will send you to the upsell page. On prepaid you can add more data when you use up the 200 free mb.

ok--thanks for the update. I envy that yours is working because I want the flexibility to use Waze in either the Fire Phone or my Samsung Tablet. In any case, yes, I just started a new monthly cycle and I have about 163MB left. I tried one more time and verified that I'm using the correct APN but I still get the same result. My prepaid SIM was indeed activated in a T-Mobile tablet so there's that. And mine was only done about a month ago so maybe something has changed over the last year.

Sorry to hear it I must be flying under their radar with 2 non t-mo devices. Maybe other peeps could try it and post. It would make it clear then that my case is different. It will be really nice since my main sim is att in an iphone.
If you're adventurous, ebay is selling simple mobile preloaded sims for about $5 each. It has 1 or 2 gigs of data and unl. talk and text. I got 6 of them when they were
$1/each and I have 1 left. They were all activated without a hitch following the directions enclosed with the sims. I would buy more but am too cheap to pay the going rate for them. Maybe $5/month would be worth it to you. You can always buy 1 just to see if it will be good for you. Simple runs on t-mobile.

Sashusmom, thanks for the tip on simple mobile--will def look into that. Another thought on the prepaid TMO SIM working on your Fire phone and not mine: could it be related to our ROM setups? I am stock rooted. What ROM if any are you running and are you using any special build prop strings?

I'm running CM-11 for safestrap by ggow. Rooted, no build prop changes. I never used safestrap before but it was very easy. I tend to re-read stuff 3-4 times before I attempt new things and read every post before making any rom changes. Maybe overly cautious, but I never bricked.

I installed safestrap and flashed CM11 for safestrap to try to match your environment. I also never used safestrap before and the good news is that it was surprisingly easy. The bad news is that it had no impact on my TMO prepaid card working. Thanks again for your suggestions.

Your very welcome and I'm sorry it was a bust for you Let me know how you like CM11.

I am about to do similar task. I have an old Verizon RazrHD with sim slot. Ordered a TMO phone sim (not tablet). It will arrive this Thrusday. I hope it will work. I don't think build prop will help because TMO has a thread about adding new devices to TMO DB, they use IMEI.
