What do folks know about the MT4GS on the AT&T network? I used the Sensation exploit to sim unlock the phone. Got the code, entered it and it says network unlock successful but I can't get it to connect to the AT&T network once I insert the AT&T sim. I attempted to add the AT&T apn settings to the MT4GS but they won't save. I have a network unlocked MT4GS and an AT&T sim card.
Can anyone offer any advice?
Is your sim card activated? And have the proper data plan?
You need to go to the att store and have it activated and then have the towers updated.
Thats what my brother in law just told me who works at att. He said you can call them as well.
I actually have an att sim he gave me thats active, but needs to be paid, so i couldnt test it. I used it to unlock the phone.

Love you all are weighing in so quickly to help me think about this problem. XDA really is the best. I've tried all the things suggested and still no luck. I just had a thought that I'd like to run by you all. The phone is 4g. Do I need a 4g sim card from AT&T? The sim card is active. It's moving from an unlocked T-Mobile Vibrant to this unlocked T-Mobile MT4GS. So I know that the sim card works and can be used in an off-network device. But I don't know much about 3g/4g and sim cards. The current plan is 3g data on AT&T.
The problem is that the MT4GS behaves as if the sim isn't even there. I can put in a Simple Mobile sim and it fires right up. I can put the AT&T sim back into the Vibrant and it works right away. So how do plans work with sim cards?
If it is a 3g plan will the MT4GS not even see the sim card?
You guys rock.
It could be. make sure the sim is in right way and it isnt badly damaged. Since simple mobile works it leads me to think the sim is having an issue of some sort.
I would try getting a new sim from att with a 4g plan, see if that works. If im not mistaken, theyre free, if you get a paid plan.

You will not get 4g on the slide, so you don't need a 4g card. Differing spectrums. Vibrant gets 3g on ATT but its the only one.

After you enter the new AT&T APN settings make sure you hit the menu key to actually save the APN settings. Just hitting the back button well NOT save the settings at all. I'm using the MT4GS with my AT&T account and everything works great. Although you well NOT get 4g or even 3g, you well get 2g.

Sent from my Sensation_ReMiX using Tapatalk
Just wanted to confirm it's working here too. AT&T sim (it's a 4G sim, from my SGS2) in a sim-unlocked myTouch 4G Slide running Bulletproof 1.something. APN had to be entered manually, but I didn't have to manually tell it to use AT&T.
The issue was Cyanogenmod. I don't know why or how but once I flashed Bulletproof 1.1 it took the AT&T sim fine. I reflashed CM in order to verify and it wouldn't take the sim again. I don't know. After flashing Bulletproof 1.1, I used the Tweakker app (an app I wish could be included in every rom) to get my AT&T APN settings and everything worked from there. Thanks everyone for the troubleshooting help. I don't know why it seems to have issues with our CM rom and the AT&T sim card.
The phone is, as we all know, limited to the edge network while on AT&T. Thanks peeps.

So heres a question. When i talked to the sales rep they said i would be getting a new sim card. So if thats the case is the new card compatable with my current Tilt 2 phone (HTC Rhodium) since the Inspire is not a world phone?

Sounds like the sales rep you dealt with was a confused. New sim cards have been released for LTE, but they are not supposed to be activating them until the old sim cards are depleted.
AT&T has released a new batch of SIM cards that will support HSPA+ and future LTE devices. I have attached a image of what the new SIM looks like. You will not notice any difference between the new SIM's until you begin using LTE devices in 2012.

Not true. SIM profiles will change and when you upgrade to a new data network the older SIM may not have the full profile and can't get it via SIM OTA.

you guys do realize that ATT is marketing their 4G, when its actually only HSPA+?
also, you seem to think that the SIM card is going to need to be changed for '4G' speeds? why? the only thing that needs to change for '4G' is the hardware has to support it.
SIMS cards do need to be changed from time to time because of types of services or network upgrades.
Older SIM cards may still work but that doesnt mean you will always get full network/sevice potential.
There is good reading outside of XDA about this if you search a little, and ignore the junk search results

What's this then:
http://www.bgr.com/2010/10/21/att-starts-switching-to-lte-compatible-sim-cards/
Cingular changed their UICC profile (SIM) in 2005 when they introduced ISIM and USIM profiles to support 3G. Now to support LTE, they've introduced... wait for it... a new SIM! OMG!!!!
BTW, LTE unlike HSPA+ uses a totally different core called EPC and thus has a different APN and several other new profile settings.
BTW, BTW, APN is typically a device driven setting and NOT a UICC setting. There's a difference.

Anyway, AT&T shipped me a new SIM when I received my Atrix 4G. Not really sure if it's necessary but AT&T did that.

Since you have practiced, you should be correct. I didn't get a chance to test my original SIM in Atrix.
However I still recall my China Mobile SIM didn't get 3G while roaming in US... Maybe just my problem.
What will happen? Will the phone activate just like on AT&T? I know you cant switch back and forth with an iPhone since its all 3G CDMA etc... but will the sim chip change that? Can you hot swap?
It should, from what I heard, work like any other GSM phone.
So yea, your SIM should make you be able to make calls, text and data on the Charge.
Yes you are correct

You still must register the device in their system. However, once you do, its all activated.
Is there a reference, like a white paper or a tech spec that can actually answer this question? This Tbolt is not the first Verizon phone I've had with a SIM card, and just like this thing, they worked just fine without the thing. How do calling functions transfer with the card when it has nothing to do with the SIM card or LTE?

Per Verizon Website:
http://support.vzw.com/clc/faqs/VZAccess/4g_sim_card.html
Yes. You may activate any 4G LTE device that has been certified by Verizon Wireless to be compatible with our 4G LTE network, including devices not purchased directly from Verizon Wireless. Simply activate your 4G SIM card on a Verizon Wireless price plan.
I don't see anything that say you have to activate the device only the sim card.

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.

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.

Can I switch my verizon s3 sim card to a att one x?
I have looked up apn's and such but every time I put in an apn, then click save...it isn't there. There are no apns on the phone at all.
I have been on Verizon for over a year. I like their coverage but they are expensive each mo. I picked up this phone from a person who needed money, said the phone had been cut off because they couldn't pay their bill. They had unlocked it and rooted it before it was cut off. I can get on internet and use it as long as I am around wifi (except for phone calls of course) but I would like to get it to work and switch to Straight Talk.
When I go to settings and networks it says "Disconected because service is unavailable" I click it anyway and go apn's. there are none there. I make a new one and save it and it disappears. This is done when I have my verizon sim card in it. When I take the sim out I can't get to the APN's they are grayed out.
Any suggestions? Thanks so much...

This.
It will not work. Verizon uses a completely different network that your One X is not capable of connecting to.
Verizon uses CDMA for voice and 3G, which doesn't use a SIM. I've never used Verizon, so I'm no expert. But just doing a quick search it looks like the SIM is only for LTE. Plus, Verizon doesn't use the same band for LTE that AT&T does, so even LTE is not going to work on this phone.
http://support.verizonwireless.com/information/4gsim.html
As a rule, GSM phones will not work on Verizon. There may be some exceptions (such as phones that have both GSM and CDMA support). But the moral of the story is that you need to do thorough research before buying any phone that is not direct from your carrier, as failure to do so may mean spending your money on a phone that does not work at all on your network.
The phone will work on Straight Talk, as ST uses AT&T and T-Mobile, which are both GSM carriers.
