Possibly simlocked?

Is it possible I bought a simlocked I9020A? Works fine on at&t but my tmo simcard wont work at all (no edge). I got it off craigslist but did a factory reset, so figured anythng the previously owner did should be undone.

Aren't all GSM Nexus devices unlocked by default, only difference being GSM/3G frequencies?

So why did you buy an att nexus s when you have T-Mobile?

If you're able to make calls with the tmo sim then it is already sim unlocked. Though I am not sure why you're not getting edge.
Btw, is it rooted?

Wrong apn settings?
Sent from my Nexus S 4G using xda premium

yeat I thought I'd at least get edge with a Tmo sim in. I use ATT in the US, the Tmo sim is my womans and was just to test it since since we are traveling to Europe in two weeks.

It won't hurt to check your IMEI and /efs
Sorry, didn't see that it works on AT&T :/

You should get Edge at least. Guess there's something wrong somewhere else. Talk to your carrier. If you can use some features it's not simlocked at least.

I would try adding a tmo apn. Not sure if it'll work but worth a shot.

I have the same problem, but the other way around. I have an I9020T which does not seem to work at all with AT&T. I've made many phone calls to Tmobile, to AT&T, and to Samsung's tech support. I haven't found a resolution, yet. The last thing that was told to me by the AT&T tech support person this evening, was that perhaps I need a newer simcard - one that is fully compatible with this newer model of phone.
I'm also prepared for the possibility that the phone has a hardware defect, however I don't want to send it in for an RMA until I'm absolutely certain.
Samsung (after checking my IMEI) has told me that the phone is definitely sim-unlocked and usable on any carrier.
A couple helpful hints when talking to any tech support person:
Make sure that they cross check your IMEI number. They have a database, and if they can establish some facts about your phone that way, it can really expedite the process.
Also, be aware that tech support people step through flow charts with you, and they usually aren't actually very technically savvy. If you can get them started on a constructive tack - they'll find the right flow chart, and you might get a lot more help than if you simply call up and say "it doesn't work."

myTouch 4G Slide sim unlocking

Here we go with yet another unlock solution.
This one applies to almost (if not all) devices which are radio S-off, it’s fairly easy to use and doesn’t wipe data/settings nor have that ugly side effect (when using diag files) in which you lose conectivity to mobile network.
Supported devices so far:
HTC Sensation (pyramid)
HTC Evo 3D (shooter)
HTC EVO 3D GSM (shooteru)
HTC myTouch Slide 4G
Click to expand...
Click to collapse
(by the use of revolutionary)
and:
Sprint EVO 4G
Droid Incredible (HTC Incredible)
HTC Desire CDMA (HTC BravoC)
Click to expand...
Click to collapse
(by the use of unrevoked 3 – not tested)
These are the required steps you have to take:
1. S-off your phone by using Revolutionary (if you haven’t already done that).
2. Fill in the form with the required data. This will generate an unique Config.dat file for your device. Please enter a valid email address, as you’ll be sent there the link to download the file.
This step you'll have to take here
3. Put the file on the root of your sdcard and reboot your phone into HBOOT (adb reboot oem-42). Once you’re there, navigate to Simlock and press Power. The phone will load the file and remove the simlock. Some text will appear on the screen and at a certain point you’ll be asked to press Vol-Up to restart the phone.
4. Just do it, and you’ll be done!
PLEASE NOTE!:
This solution is heavily linked to the device it's being applied to by the use of IMEI, which can be considered a breach in security.

This solution provided for you on this site is given AS IS and in GOOD FAITH and is based on the research I made. I may not accept any liability or responsibility for the use of this applicaton.
If you find this tool useful and appreciate my work, Paypal me a beer, it helps development a lot..

Not for certain circumstances.. T-Mobile will only give it you you if you meet some criteria.. i.e. you're account has been active for 6 months.. I don't know what the actual criteria are.. that was just an example...
not to mention that you have to wait over 24hours to get the email with the unlock code.. this method was a lot faster than a half hour phone call with a t-mobile rep.

I was a customer for about 6 days and was given the code over the phone.

my touch 4g Slide NO CALLS with S-off sim unlocked METROpCS
So its 2014.. I know I should get a better phone.. Good news its I got my my touch 4g slide bootloader unlocked and S-off. Also did the sim unlock on the site that emails you back the file and unlocks the sim.. BUT here is my problem
when I put my metro sim in the phone.. no matter which rom I load (which I can now load rom recovery from sd) the phone wont work..
When I go into the settings metropcs and att show up but when I try and select it, it tells me not allowed right now, or sim card doesn't allow that connection. So I cannot get it to work. Is there a way they are locking sim cards to their phones?
I would have thought getting S-off and running the simlock file I'd be good to go.. Anyone PLZ help I am desparate to figure out what is wrong here.

Picture Of S-off UNLOCKED bootloader NO SVC
Here is a picture of the phone.. Likewise no SVC with metro sim.. I don't have a tmobile card to test with but I think either the sim lock didn't work, or metropcs is somehow locking the sim to IMEI
Anyone with ideas here plz help. If it is IMEI to sim is there a way to unlock sim or change iMEI? I know its illegal to change an ESN but imei..
Also if its blacklisted would it be blacklisted for metro too?

So I thought of a couple things. With a little research, one got shot down right off the bat:
http://www.phonescoop.com/carriers/carrier.php?c=11
http://www.gsmarena.com/t_mobile_mytouch_4g_slide-4018.php
Some carriers use weird frequency bands that the phone wouldn't support. MetroPCS uses 1700 or 1900MHz (depending where you are), which the phone totally covers. So not that.
Related to that though, is the APN settings. If you have more than one (my Rogers setup has 4), it may be stuck on an APN that just isn't working for you. So Settings > Mobile Networks > Access Point Names.
Finally (just thought of it), you may want to test your MetroPCS SIM card on a different (smart)phone. I had recent problems with my SIM (I guess it was swapped out too many times, besides being 6-7 years old), although it worked fine on a feature phone. And if you can get your hands on a different SIM (T-Mobile or otherwise), and encounter the same problem, it could very well be a (hard-to-resolve) problem with the phone. If it is blacklisted, it would be blacklisted nationally if not internationally, and there is an IMEI database to check it against:
http://www.imei.info/
Hope this helps.

Check your imei for blacklist status on the tmo website. MetroPCS is now wholly owned by TMo, it shouldn't need to be unlocked. AT&T and Tmo share blacklist data as well. If your phone is sketchy you are out of luck.
If the SIM is old you might try a new one and see if that helps.

I was looking into this, and this forum thread came up:
http://www.howardforums.com/showthr...-married-to-ESN-of-one-phone-only-that-sucks!
Looks like you can transfer phones by letting MetroPCS know of the new IMEI, but you cannot register two (or more) IMEI's for the same SIM. So depends on how you want to use your Doubleshot. I'd give them a call (or better yet, go into their store), maybe the old IMEI will still work (the thread was a bit iffy on this result) with the new (Doubleshot) one entered.

Thanks

Wow! so that's a bummer. I really like the doubleshots keyboard but I think the exhibit from them is better. Although I tried several firmwares on it and Netflix will no longer work with custom roms (thank DRM for that) I did get hella mods to this one, but would love to have both, I was thinking the sim was somehow locked. I have a sim reader any software to check? copy clone??? new to GSM, but know lots about CDMA.. I wish it were easy to just clone IMEI like ESNS

[Q] Changing Numbers when Flashing to different carrier

In this thread, i do not ask for any help with any flashing to other carriers. I only have a question about it
Donor: Samsung Prevail
Phone to be flashed: nS4G
So i got a used NS4G from a friend. It has his number on it
My question is...if I flash it, will I have to take the phone to sprint to get the numbers changed? or will the number change to my donor number when I flash it? oR WILL a new number appear?

by the way my donor is activated and was used before

:banghead:
Be careful. What you're talking about doing is a felony and you seem to have no idea what you're getting into.

Not to be rude but if your title is more specific, e.g. with NS4G in it, maybe there wouldn't be that many viewers. I thought it would be something I could help with, but I'm not familiar with CDMA networks. I used to be on Sprint once upon a time, and I remember I had to take the phone to the Sprint store to have them activate my number on it. Goodluck!

This may work but u 1st need to get the MSL code for the ns4g. Try the app called "get my msl" . U need this code to call sprint. Just say ur buddy had sprint and he gave u the phone.
When u call they will have u enter the phone prompt commands so be on a stock ROM so they work and it will match what they see in their monitor.
This is compared to actually having an old phone that u wanted to switching to ur number.
Now they may catch on or say that the phone was never a sprint phone since the ESN # behind battery isn't in their system. So hopefully they don't bring that up.. then ur good just as long as u did the flashing correct.
Good luck

Felony? How about the carriers give users the ability to move a phone from one cdma network to another just like GSM phones are capable of. Is unlocking a simlocked GSM a felony also?
What should be a felony is having a user buy into an expensive 2 year contract by spending $299 on a phone made in China for $180 cost and not letting you use it anywhere but their network even after the contract.

Its sad you have to go through such measures just to get a decent phone without paying an arm and a leg for it. But to answer your question if I understand correctly, one you flash it and use the donor phone on ns4g it will look like the donor phone to sprint or other cdma carrier on the network. So the old number should no longer matter and the ns4g should register the Samsung Prevail number.

OK thanks for the help

I got my NS4G flashed to boost, it is actually more than a simple flash, the ESN is changed to that of the donor phone. So sprint will always see it as the prevail. Just remember the prevail can never be used again without changing that ESN also.

You need to have your NS4G connected as USB modem.

my 10c on the matter - the number is tied to the SIM card you are using. No matter what you flash, you can't change that. My advice - do not play with this type of things, you'll get your phone locked up and from there on it's all downhill

He's talking about cdma phone. Flashing to other carriers is done ONLY on cdma networks for one reason and one reason only... they don't have sims.

Besides SIM unlocking you need to perform the US band unlock as described both here, on Rootzwiki, and who knows where else, to use the DROID2 GLOBAL on AT&T or T-Mobile.
As AT&T uses standard WCDMA bands, yes, it will work with their 3G voice/data network as long as the band unlock hack is in place.

You can perform the hack yourself provided you buy a SIM unlocked device.
Refer to http://forum.xda-developers.com/showthread.php?p=22769743 for instructions. Do note that whenever you soft-brick your device you will need to SBF back to 2.4.x and apply this hack.

Dumb phone plan from who? If you get everything done (band unlock as described in the other posts) you can use your phone with an AT&T SIM and don't need any plan at all from Verizon. Is the theory that AT&T won't recognize it as a smart phone because it is not one that they ever sold?

Any non-carrier-locked GSM phone that has compatible bands can work on AT&T's network. You don't even need a list, just check which bands AT&T uses and check the phone's tech specs.

I think the problem is that people don't want AT&T to recognize the phone as a smartphone and helpfully add on a data package on postpaid plans, (presumably these people are intending to use Wifi for data). The claim was made that some people had moved a SIM from dumb phone to a smartphone purchased elsewhere, and suddenly they got billed for a data package. See, for example, http://www.zdnet.com/blog/bott/can-at-t-really-add-a-pricey-data-plan-onto-your-wireless-bill/2667
In the past, there were posts saying that you were "safe" if you used a model that AT&T had never sold, as their system would not be able to recognize it as a smartphone. Not sure how true this really is!

They probably detect it based on IMEIs. But yeah, it's just a speculation without clear facts.

search around a bit. radio is subjective, two people with the same phone and same service in the same room will get different results with radios. best thing is try a few out and see if any are better for you.

Simple mobile uses tmobile bands therefore you only will get edge speeds, try the Att go phone sim from Walmart you'll get great speeds and maybe straight talk
Sent from my Inspire 4G using xda premium

The one issue with GoPhone is that if the SIM has been activated in a different phone, and less than 6 months have passed since it was activated, you will likely get an IMEI locked message. This doesn't mean there is any issue with the Inspire, simply that the GoPhone SIM is locked to the IMEI of the phone it was activated in.

I use red pocket mobile. In northern cali. Runs on ATT hspa plus. Not bad no issues. T mobile doesn't offer a 3g plan. Red pocket is 50-60. Might want to look into it.

The six month policy is for unlocking the phone to other carriers. you have it backwards, my friend. If you call them and tell them that you are changing phones because the one it was activated on was damaged or non functional anymore, they will send a code to the phone to unlock the SIM. I think they can only do that for a SIM that is locked to an Android. If it was activated on a non-smart phone, you can go to any AT&T store and tell them you want to change phones and they will do it.

Not sure what you found to be incorrect in my statement. I never claimed the gophone sim couldn't be unlocked to be used in the inspire, just that it is locked by default to the phone that it is activated in. Also, though what you say is true about being able to get it changed, by default AT&T personnel don't seem to be able to diagnose the problem, when you give them the error message. A friend of mine had this issue when he tried to use a gophone sim in a nokia smartphone, and after going to the AT&T store, calling them up, etc, he asked me and I told him his SIM was probably locked to the phone it was activated in. Once he knew this, he called, and they unlocked it. However, neither the store nor customer service was able to help him, until he told them what the problem was. I also picked up the inspire I am using now for cheap, because the seller tried putting a gophone sim in it, and it came up with an "IMEI Locked" message. He assumed there was a problem with the phone, and AT&T customer service was unable to help him. Knowing the issue with GoPhone sims, I bought the phone, and have had no issues with it. So, though what you say is true, you have to know about the gophone simlock issue, in order to get it resolved.

Please post all questions in the Q & A section. Thanks! Thread moved.
