Hello all, I'm about to purchase a Mytouch Slide for use with AT&T, and wanted to make sure I wasn't going to have any issues with anything not working (GPS, SMS/MMS, etc.). I know I won't have AT&T 3G, only EDGE, but I can live with that. I searched but found very llittle on the subject, I'm assuming thats because both this handset, and this section of the forum, is fairly new.
Hopefully I'll be able to learn more about the handset in the next few weeks, and be abe to start helping others around here too. This appears to be a rather productive, professional forum. To that end, I'll say thanks in advance
What exactly are you asking.
So far the only people I know of, that can unlock this Phone is T-Mobile. Also, you must have an account in good standings & be a customer longer than 3 months..

What, really? So, I can't just buy one from, anywhere, and go use it? I'm new to this whole unlocking thing (CDMA background, and I work for a CDMA carrier), so I'm not really sure how the unlocking process even works. I guess that means I'd be much better served purchasing one that is already unlocked?
Well you can ask them lol but yah Check local listings new mytouch slides are only 300 and get them unlocked idk XD sorry

I'm sorry, I don't understand what your post says. The MyTouch Slide is significantly more than $300 new. It was posted above that they can't be unlocked. Are you stating that infact isn't true, and they can be?

unlocking works the say way it does for CDMA as it does with GSM. The only difference is instead of having to take my GSM phone to my carrier (or call them) to have my ESN number changed to my new unlocked phone like i would have to do with a CDMA phone. I can just pop my SIM card into my new unlocked GSM phone.
Even if you work for a CDMA carrier you should know that. If you work for any cell phone carrier you should know that

I understand the idea behind being able to take my sim card out of one GSM phone, and put it into another. The network looks for the info on your sim, not your ESN/MEID. And honestly, the only carriers that 'unlock' any CDMA phones currently are a couple of the pre-paids (MetroPCS & Cricket) as far as I know. You can't take a Verizon phone to Sprint, or visa versa. I work for a MetroPCS retailer, I know all about flashing CDMA phones to the MetroPCS network, and it's alot more than simply opening it up to be able to be used with anybody. Not to mention needing to use a 3rd-party flashing software that will flash Metro info to the device, as well as extract the MEID from the handset and add it to the MetroPCS database so the MetroPCS activation system will recognize it as a usable handset. So, it's really not a fair comparison.
Regardless, it still leaves my question unanswered. I've never dealt with GSM phones outside of simply buying a new one at the AT&T store. Being able to 'unlock' it to use with any carrier is a new idea to me. So, instead of everybody telling me I'm stupid and that I should know how it works, can ANYBODY point me in the direction of an explanation of what it takes to unlock a GSM phone, what changes need to be made, and why a MyTouch Slide is special WRT it not being able to be unlocked?

Might I ask how you got yours unlocked?
I got mine unlocked from theremoteunlocker.com
Gsm phones are locked via its hardware just like how when you use your pc the bios is software interlayed into your mobo so they could lock it if they wanted to only accept the types of processors they accept e.g tmobile locked their phone (the mobo) to only accept the tmobile simcard (the processor) the unlock code is a delevoper or admin unlock code that removes the simcard lock so you can use any simcard on it

Got it, I just figured that out from reading the website that you said you used. SIGNIFICANTLY easier task than 'unlocking' a CDMA handset. I've already sent them an email, if I can infact get one unlocked, I'll be buying one this week. Thanks!!

Look around on tmobiles website, the have the conditions for giving you a unlock code posted. If you meet the conditions they will email you the unlock code.
I did it with my slide, I called them Friday and they emailed me a unlock code by Monday. Free and easy.
Found the URL. http://support.t-mobile.com/doc/tm51885.xml

I'm assuming by perfect you're not including 3G since the slide isn't set or rather, doesn't contain the correct radio module to use AT&T's 3G band. Or does it and we're being lied to by the carriers (no surprise there) hmm...
Hi all,
I am not sure what subforum to post it so forgive me if I've chosen wrong...
I have an unlocked HTC Desire HD bought in Europe (Poland in particular). I am currently in US for some time and to my surprise it does not work with AT&T GoPhone SimCard I hoped to use it with. The phone says "no simcard"...
Does anybody here knows what's the reason? Is there a way to correct it (load a different ROM onto the device?)? Or - if it's impossible to fix with AT&T - what are my options for finding a prepaid (I won't be here for a year to justify signing on for a full year contract) card that will work with this phone and have some decent data plan?
Poland uses GSM network and usually in US they use CDMA so it is not possible to use your DHD in US if the carrier uses other network than GSM because the 2 radios are completely different. Not sure if this can be changed but doubt it.

I don't think this is a case.... This phone is AFAIK the same phone in technical terms as HTC Inspire being sold in US. This is a quad-band and is working in US with Polish sim-card in roaming mode (with horrendous prices of course). So this is something with a sim-card and/or radio-software compatibility. I would push for the first one as the phone is saying "no sim-card" signalling problems with recognizing it.
Hey
i think your problem lies in the frequencies used by european phones, arent the same as in us... on my old HD2 you could change the freq, but afaik its not possible with android phones... check this chart http://www.worldtimezone.com/gsm.html
hope u solve the prob.

Once again - I am afraid it's not that simple...
Once again - I am afraid it's not that simple... I believe the incompatibility is somewhere at the either sim card (being rigged in some special way by ATT) or radio software. The HTC Desire HD is a quad-band phone accodring to it's specs (I've checked at the GSMArena . COM). I've seen reports on the internet that people managed to run GoPhone simcards on unlocked HTC android-based phones. I just kind find any information about what might be wrong (incompatible) with my handset
Thank you for your replies anyway - hope someone will have other ideas what to do, otherwise I am stuck with $20 "phone" I got with my gophone card which is making me upset while having a proper phone not working...
RESOLVED!
I managed to google out the information that ATT is somehow locking the GoPhone simcard to the phone it was bundled with. I had to call Customer Support to get it unlocked which they did. Now my Desire HD is properly working with data plan accessible
Thanks for anybody who was trying to help me with this.
Regards!

Does anybody know the access point configurations for an HTC Legend (or similar european HTC device) to access data on GoPhone on AT&T?
Thankss
Can a bad esn phone move to another carrier and be used normally?
What does bad esn mean
TX!!
No it wont transfer to another carrier, and it is caused from a phone bill not being paid, or a phone being lost or stolen and reported to the carrier. If you flash a phone to another carrier or use have it unlocked, then the phone will work on other networks, just not the network the esn was banned from, until the bill has been paid

Best answer i think, let me see if I understood!
You can unlock the phone, and then flash a ROM. And the NOT original carrier would work.
Is there something like that with IMEI/GSM?
I have been searching for a cheap note 2 n it seems that bad ESN phones are the cheapest....
So my question is If i buy a sprint bad ESN note 2 will it work in India with a CDMA connection... Will I have to unlock or flash it before using it...???
And if yes can anyone point me to the right thread or a tutorial...
Thanks in advance...!!

you would have to flash it. you will need your new carrier's prl and 3g connection port e.g. (123)[email protected] then just use qpst and configure, or find someone over there to do it for you
I would suggest you buy a World Phone with a bad ESN so that it has a GSM slot , even though it has a bad ESN you will be able to use it using a indian GSM sim card !
SO dont buy a Sprint/Verizon Phone with bad ESN ! Verizon's new phones with 4g capablity are GSM radios enabled so you can buy those
Hi guy,
please, let me know if I read right thing...
I can buy a phone with bad esn and use phone with normale sim card gsm ?
or I must unlock the phone buying code on line?
must I flash phone with another firmware ?
are these instruction valid for all verizon phone ?
Thank you so much
I sorry for my bad english and ignorance
Paolo
You're better off just buying a phone with a good ESN, if you plan on using CDMA in the States. Otherwise, if you plan to use GSM then just get a new Nexus 4 or Galaxy S3 (they're cheap now.)
The reason bad ESN phones are cheaper is because people use them for parts.
Unless your phone is an international phone, it won't have a sim card in it. Verizon in the states runs on cdma.

Just to clarify this better, *MOST* US CDMA phones (Sprint, Verizon and many else) have SIM cards built-in and you can't swap. Besides, quite a few of them doesn't support AT&T / T-Mo's HSPA+ at all, so swapping another SIM (likely HSPA) usually makes no sense.
For example, in China here, the Epic 4G Touch from Sprint is modded to expose its SIM slots, making it possible to swap SIMs, but because E4GT isn't a "global phone", it lacks HSPA+ support and can only use CDMA SIMs (in China, that is, China Telecom).

So hold up ...
Can i buy an S4 with a bad ESN from At&t and then unlock it (there are free and paid for solutions) and then use that same s4 on tmobile ?
The main question is within the USA do different networks share banned IMEI and ESN lists ?

No. You have to use a device that has the proper network type (GSM vs CDMA) & frequency range.
Plus, how are there any bad ESN S4's already? The damn thing is brand new.

Apparently no one HAS TAKEN A BAD ESN phone and successfully flashed to another ROM carrier...otherwise there would have been tons of comments by such a person on this thread by now. ;-/
I can add that anyone wanting to use the s4 active on TMobi (i537 or i9295) will not be satisfied because you can NOT use the TMobi wifi calling and you can not tether. You will also have to go through a process to add HSPA frequency in order to get a decent data and voice signal in most locations around the midwest. AND with the i9295 international... you will not be able to use LTE/4g data speed networks!
I'm selling my unlocked and rooted i537 right now for $175 because I want my TMobi wifi calling and tethering back. I did not find out about these issues until after I had already bought the phone. Anyone interested? hit me up....
I'm a new to ATT and was wondering if a lost phone can still be used inside/outside the US when inserted with a SIM card? Or is there something that blocks the phone?
You sound like the guy who "purchased" a GS3 on Craigslist which was sim locked by AT&T when it was reported stolen. Honestly, why would it matter if you're new to AT&T? If your phone is lost or stolen then report it and they'll in turn shut down that SIM. You can report it to Samsung as well who may track stolen devices no matter the SIM entered.
Won't give any other answer as I'm sure it's a violation of the rules to aid criminal like behavior.
Sent from my SGH-I747 using xda app-developers app
Haha. if i had "purchased" such a phone why would i ask? couldnt i just see for myself..?
Why would it matter? cause i just switched from VW, which as you know doesnt use SIMS.. I also just came back from a trip overseas where everyone just switched their SIM cards on the plane.. so being a new ATT customer i was wondering how that thing works.. if phones can be locked despite putting a different SIM locally/internationally.. it's just good honest curiosity. ATT CS did tell me i can put any ineternational local SIM and it'll work as long as its a partner..
You kinda sat yourself up for those kind of comments. You didn't ask in the OP if a phone could be used in/out of country.... U clearly said "lost". This is they word that will probably lead everyone that reads this post to think that 1:its a stolen phone or 2:what the guy above me said. Just making an observation.... If this is not the case maybe you should edit your OP to read differently.
Again.. this is just curiosity.. i don't understand why we can't talk about this.. i asking in general how SIM technology works whether it's active or deactivated.
Since you guys like scenarios VS hypotheticals here's one -- Imagin i lost my phone and bought a new phone under the warranty.. then later found my old phone.. will it still work if i put my SIM in? will i need to report that i found my phone? Those are valid questions that should get valid answers...
SIM cards will work in any phone. You not have to call AT&T to have them activate it. Although I don't know if the new lte SIM cards work in older 3g phones I'd assume they should. And you'd have to return one of the phones because AT&T will block the imei of the one reported lost or stolen. So you generally return the lost/stolen phone.
Edit: Also we should stop treating everyone like criminals because you find the post "suspicious".
Once reported lost or stolen...at&t will block that imei. So no, if you find that lost phone later...it won't work on at&t. Get it sim unlocked and sell it.

here is a set of answers that should help your curiosity, since you are new to GSM/WCDMA-based networks (aka most networks that aren't VZW or sprint):
1. SIM cards can be switched in phones very easily. AT&T's 4G LTE SIMs can still be inserted into previous non-LTE phones (i.e. an old Moto Atrix) and it will work fine as long as the SIM card is valid. Your phone account/line is tied to your SIM card, NOT your phone. this is useful for those who have 'beater' phones for clubbing/debauchery nights.
2. phones from providers such as AT&T are usually SIM-locked, meaning you can only use an AT&T SIM in them. You can use other AT&T SIMs (say, from another account/line) and it will still work fine.
2.a. If your phone is reported stolen to AT&T, they will blacklist the IMEI and it CANNOT be used on AT&T's network anymore, period. So if your phone is stolen, you can have it barred from AT&T. This is why people who buy phones off craigslist often run into issues - the phone is actually stolen. There are no workarounds.
2.b. If you need to use your phone with a different provider's SIM (i.e. another country carrier, or t-mobile) then you need to get it unlocked. this requires a code that you input when you insert a foreign SIM. you can buy this code or get it from AT&T for free, pending a few requirements.
3. Verizon, now that they have an LTE network, uses SIM cards as well now.
Per the insurance rules if you do find the "lost" phone you are supposed to send it to them. I know they black list stolen phones, but from my experience they do not black list lost phones.

I just upgraded an Atrix 2 to an Atrix HD; and after 3 weeks the Atrix HD for a GSIII (fix your software MOTO!). Well between those two phones they switched the SIM card form factor. The Atrix 2 had the ones they've been running since ATT bought Cingular; and the Atrix HD used this one about 2/3 the size called a micro Sim card.
My question is this; can I use my micro SIM in my Inspire 4g I have for a backup?

yes you can. if your slot is snug enough and not a push-slot you don't even need an adapter, just put it in so that the contacts are correctly aligned and it will be fine. did this all through europe when my SGS3 batt died.
I've wondered the same thing. Coming from sprint, I had to verify the ESN wasn't bad if buying used. This one done by calling sprint. I assume its the exact same thing but calling ATT with the imei number to see if its clean?

Make sure it's the unlocked GSM version, which can be used with any GSM provider. The CDMA versions are locked to their respective provider, as far as I know.
If it's an i9250, which is unlocked and GSM, you can use it with any prepaid GSM carrier like Straight Talk, T-Mobile, etc. etc. etc. These models don't have any branding on the back, so it just says "Google" and "Samsung". Although I'd be wary of buying it unless he has an active SIM to test in it to make sure everything's OK.
If it's a Sprint or Verizon model, don't bother with buying it to try and flash it to another prepaid CDMA carrier. Just buy a GSM model.
