Recently, I got a prepaid T-mobile sim for using in a business trip. After the trip, I put back my original T-mobile sim in. But, the Amaze does not recongize it. I tried my original sim in my wife phone, it is recongized. I have tried several working sim in the Amaze. The Amaze does not recongize any of them.
I put back the prepaid sim, it works. It only recongize that particular prepaid sim. All other sim does work in it, it just shows No SIM Emergency Calling only.
It is a very very strange problem. Any luck to solve it ？
my amaze is running custome 4.2.2 rom. sim unlocked. s-off.
It worked fine (can use different sim). before using thatparticular prepaid sim card. Now, it seems that it is locked that particular prepaid SIM.
please help!

Have you tried putting in the SIM you want to use then going into your Mobile Network Settings and searching Network Operators, then selecting the network; and/or, resetting your APN to default?
yes. but it did not work.

My understanding is that a phone does register on T-mo and associate the IMEI and SIM. If you've ever looked at your Plan on My T-mobile you see that your phone is listed. When I switched from a Wildfire S to the Amaze it did switch after a couple days and show the amaze...all on its own, and of course for that phone number...but I was not switching SIMs with different numbers or 2 different SIMs with the same number, whichever is your case. There are a lot of variables that you didn't mention, so instead of the 20 question thing I would respectfully suggest you just call T-mobile and get them to switch things. I know, I know, I like to figure this stuff out too, but sometimes you just have to have them help. Alternately, of course, you could just do a live chat with support...might have to get a support login (they are separate from My T-mobile logins).
My phone is sim unlocked. When I put in att sim , it still say no sim card. I tried different sims, it always says no sim card. It only recongizes that particular sim card

Got a lot of conflicting info on this.
1.Are different sims given for smart vs dumbphones? 3G vs 4G? Etc
Ie: will a smartphone not access 4g on a GoPhone sim?
2.Can a Rep on the phone identify your phone by the imei?
Thank you for any enlightening!
I may be wrong but I think the gophone sim works differently than a regular sim, there are att sims that say 3g but they work just the same as the new sim cards att is using, as far as the rep being able to tell ur phone make and model by the imei that's a yes for sure, they can detect what phone you have without you giving them that info and slap the $25 2gb data plan on your account.

To put it simply- if the network system knows that X phone has X IMEI or even model code it shows when it connects (I777 vs say I9100) and its endorsed by them, then they'll know what it is.
Do you want to know this to avoid paying ridiculous data fees? If so, get an international unlocked/unbranded phone that your carrier never had/in their system. I've been milking dumbell data rates on my Nokia E series phones for years now and not because I use the balls out of the data, but to have that unlimited/cheap peace of mind.
When I upgraded from my Captivate to the SGS2, the AT&T clerk said I needed the 4G sim card and installed one.

I received the same treatment. With my last five phones, I've only been able to swap out the SIM cards twice — once because I bought a phone on Craigslist.
Really? I'm still on my, what is it, 4-5 year old 3G sim and no problems whatsoever.

I was on my old 3g Sim card as well but when i got the sgsii it wouldn't connect to the "phone" APN, i had to use the old "wap.cingular" APN. The old 3g Sims aren't provisioned on AT&T's network to access hspa.
Before getting a new Sim card, i would never get over 3Mbps down. Now i average 5 and on good days it'll peak to 7-10.
to answer the question about different Sim cards for smart phones or dumb phones; pretty sure they use the same card because when i went the other day to get a new Sim, the rep just grabbed one from a stack and activated it, there was only one stack. Also it would cost more and bee more confusing for them as company to do that.
And at&t can identify a phone over the network only if that phone is familiar to them. So if you bought an AT&T sgsii off craigslist/ebay/friend and plug in your Sim card, they'll be able to tell.
If you buy a phone that isn't sold/recognized by AT&T, most of the time they can't tell what the device.
A good check is after you put the Sim in your phone, wait a couple hours then log onto your account online and if it shows a picture of the phone your using, they can detect it.

I have this as a gophone. They gave me a normal sim card not the go phone sim card. It has hspa + also.

Well sim doesn't really determine what your plan allows you to do, so sims are dime a dozen. I may consider upgrading my sim if they'll be able to put my current number on a newer sim, else I'm not really concerned too much. (and, for your laughs, I'm still only using Edge to avoid having gutter battery).

this is only partly true. IF you have a att phone they can detect what type of phone you have by your IMEI #. that number is cataloged in their systems however if you have a European phone or a unlocked phone from another carrier then no they cannot tell what phone you have.
as for sims there are 2 different types of sims (go phones I dont know) there is the regular sized sims and the micro sims. Micro's for att are used for iphone 4 and up and I believe they are the only phone for att that uses the micro sim. As for functionality of the sims no the old sims (3G) work with thier HSPA+ just the same.....

Same thing when I upgraded. But my sim was a few years old and pretty scratched up from being put in different phones so I figured even if it would work it was time to be replaced anyway.
When I bought the sgs2 the clerk was surprised I still had my Cingular Sim card and suggested I get the new one. I got to keep my Cingular relic.

The only problem I've run into is my mms stopped working a few days after using the phone and I'm on a gophone account. My inspire works fine. Not sure if they ran an imei sweep and the sgii doesnt play nice with gophone accounts. They still had my imei as an old nokia flip phone. You don't have to have data on a gophone, but if you want internet you'll need to buy a gophone data package.
You mean you need an unlimited $50 type GoPhone account right? No one needs a data account above and beyond that.
I bought a cheap GoPhone $50 plan today...using that sim in my Note AI get tomorrow.

I always assumed that it was used if you went abroad and were roaming on GSM/UMTS (which requires SIM cards) -- so that those roaming charges would be charged to your Sprint account.
The phone is an international model with GSM capabilities. The SIM card is only used when roaming internationally.

...and can be swapped out for a local SIM card (which will get you a local number and cheaper rates) from whatever country you are in.

I thought I heard that you needed to get Sprint to unlock it or root your phone in order to be able to use your own simcard, though.

Nope; from what I've seen on numerous other forums, people have reported no problem in using pre-paid SIM cards overseas and it doesn't require any intervention by Sprint. The only issue is that it works for voice only; not data.
From the notes of the Feb. Sprint Advocacy Call:
What is Sprints policy of using pre-paid SIM card for international phones. (certain international phones such as the Photon does not save APN settings that do not use Sprint's MCC/MNC 310 and 120. This stops any attempt to use a pre-paid SIM for data in the Photon for example). Sprint claims it’s a Motorola issue and Motorola claims its a Sprint issue). The use of data for a business traveler or the occasional international traveler is important.
1. I actually brought this up to Art when I got my Photon, and the response he got from the product team was "Sprint does not lock phones". I've heard from several people who have traveled overseas that, yes, you can use a foreign SIM card for voice (you use the Sprint card if you want people to reach you on you normal Sprint phone #), but data does not work because of the reasons stated. The problem is that Sprint blames Motorola and Motorola, of course, blames Sprint. Data is important, so some resolution (or a better explanation) is needed.

I believe that you need to contact Sprint to activate their sim card.

Yes; if you're using your Sprint number, you will have to call Sprint to activate international roaming. The question though was about using a SIM card from an oversees carrier in the Photon.

Yes, the card if for calling internationally. The phone comes unlocked and you can put any international Sim in it. I can also confirm that it is quad band. I am currently using the phone in turkey with a local sim and didn't require unlocking

I am completely stock:::: International sim cards work by simply"putting into the slot; nice and easy " thats what she said!! ..i used a telcel sim in Mexico with no issues for voice or text issues ( of course this depends on what type of service they offer with their sims. I was not able to use outgoing calls until i called their customer service and activated it) Also i was not there long enough to activate data ( nor did i find out if i could) but i was informed that you would need an apn app that can be found in the market such as APN global

Because it's a world/international phone when you leave the us you don't have to buy a new phone!
Photon
Last fall I went on a vacation to Turkey and Bulgaria, I bought local sim cards and had no problems at all. However, photon sucks at auto detecting the apn which is used for 3g data. For that just find the apn codes by downloading the app "tweakker apn internet mms" or google what it is. Usually its easier finding it yourself because when I was in Turkey it wasn't that easy for me to find a tech guy at the cell phone store, especially one that read english.
it works fine in India (Voice and 3G Data) and I love this phone
As noted, the SIM card in the Photon is for international roaming use only.
It is not used to provision CDMA service. The two large US CDMA carriers (Verizon, Sprint) have made a decision not to use SIM cards to provision wireless service for their subscribers. Instead they essentially use the phone's serial number and associate it with an account and phone number.
up up.
china telecom's Uim card is Modified before they can be used for Photon 4g.
odd question, but can i activate the Sprint sim card and use it inside the US instead of internationally? then put said sim card in another gsm phone? and use current sprint plan, not international plans

I don't think the Sprint SIM card will work inside the US.
I'm using a SIM card in Peru, voice and 3g data work without a problem. You just have to goggle search the APN settings of the operator that you are gonna use.
I'm on ICS 676.226.3.XT910.Retail.en.EU and my phone fails to register on a GSM network. All other radio modules (Wifi, BT) work just fine. Phone is unbranded.
Problems started on 672.180.33. I decided that it was a faulty radio module and installed a new leak. Unfortunately, nothing happened.
Phone is able to identify that the SIM card is inserted, it can read the contents of SIM card and it shows the phone number that is stored on SIM card. It also identifies SIM serial number via 'SIM info' app.
I did the reflash. Wiped both phone storage and internal storage. Again, no results.
Also, when doing a network operator search it finds all operators in my country. But still it fails to register while doing a manual search.
I tried another SIM card from other operator and everything is the same as with the main SIM card.
Should I get a new SIM card from my operator? Or is it a problem with phone?
Solved the problem. The SIM card was the problem.
Tried another SIM card and it worked.
Anybody using the Razr on AT&T GSM in the USA?
I called Verizon wireless and they told me that with the new ICS update the Droid Razr has been globally unlocked. Does this include AT&T in the US? I tried using a sim that I had on my AT&T phone but it didn't work even with customer support trying to help from AT&T. I'm going to change the sim tomorrow to determine if that's the problem. Thanks for the help!

From what I understand the phone is not unlocked to work on AT&T or T-Mobile. It can use most over seas GSM providers tho
Yeah i went to grab a new sim from AT&T and it still doesnt work. Although it does detect AT&T GSM/UTMS access points. As i understand it, the issue is in the software not hardware capability. Any roms that allow for AT&T use?

Hey i came to hong kong for a business trip and tried a local GSM sim but i get this sim is not supported error. DOes anyone know how to fix this.
I tried same thing sim on another phone it works. So not sure what the issue is ? did i need to get an unlock code from verizon before i left ?
If you can get access to a computer for awhile go through Adams unlock process in the original android dev forum and you'll be carrier unlocked, not sure what Verizon would give you for a code cant hurt to call and ask, but keep in mind unlocking it is something that can be done by you from here

You sure it wasn't a "Non-Verizon SIM" on going notification? I've read of people using all sorts of different carrier SIMs and they all had at least voice/sms service if they had a signal. The phone is already SIM unlocked, so VZW couldnt give you much.
Sent from my Galaxy Note II
The non-Verizon SIM notification doesn't actually do anything. You should be able to get voice just by putting the SIM in. To set up data, you'll need to be rooted and add the APN manually.
so i'm trying a fix a galaxy note att branded i717 note. my friend bought it craiglslist. here's what happens.
phone simply will not accept ANY att sim card. either "active" sim or fresh unactivated sim. same goes for tmobile sim cards. in both cases it will show "no sim/emergency calls only".
fine. i was under the impression that it should ask for some unlock code after inserting tmobile sim card, but it doesnt do that. clearly other MVNO sims didn't work either. note - both att and tmbole sims are 89014xxxxx
interestingly i had a foreign sim card (NON 89014xxxx....). => this works! instead of "no sim/emergency calls only", i simply get no service but no errors either!
WHAT is wrong with this phone? blacklisted? hardware fault? flash a different rom? any ideas?
Possible Sim card port damage...

well there's your problem, i hope you didn't spend too much on it.

I think I can help. Try resetting your phone, reinstalling the rom, or there is a bad thing going on with your phone. Are you sure itbis from AT&T? If the SIM card slots do not work, gently use a cloth to clean them. Is it a micro SIM card or did you cut a regular one down yourself? thank me if anything I mention fixes the problem.
hi, thanks everybody for posting. some strange things happening.
I tested two Tmobile MVNO (ultra and ptel) sim cards, both work! I didn't try simple mobile yet.
i found ONE tmobile and ONE at&t sim card that gets read properly. then i tried few other att/tmobile sim cards and they are rejected. !!!??!!!
I think i need to go the debug mode and change some settings there? *#197328640#
clearly sim slot is not broken. imei is not blocked.
