I noticed that the SIM cards keep changing every so often.
The new SIM cards have a smaller gold-metal surface area, whereas the older ones have a bigger gold-metal surface area.
Any ideas why?
Is there any benefit to swap out your SIM card to the newest? The SIM that comes in the box has a smaller gold-surface area.
(When was using previously using the iphone, my SIM was pretty beat up from switching phones all the time and the gold-metal part practically had indentations, which did give me reception problems. When I swapped it out with a new one at the store it did fix the problem. Obviously a surface contact problem.)

Here's the pic.
I did have a weird situation where replacing the sim actually somehow increased my data speeds...the old sim was only a year old ...but i ain't complaining
didn't really notice any less surface area tho

That's interesting....hmmm....now I'm really curious haha...
I swapped out my 1 year old SIM as well and now im getting 3G signals in my house whereas my old sim would drop 3G service more often.
Idk I change sim cards for all my phones since g1 since there's nothing on it ever since using google contacts

There is typically no need to replace your sim card unless you are having problems with it (ie not registering on the network.)
However older sim cards have a restriction on how many times they can register on the network, and after they hit the limit the phone will stop connecting, so if you want to prevent this issue (usually takes a couple years, and is a lot more likely in areas where your signal drops, for people who travel a lot, and in 3G coverages areas where you swap back and forth between 3G and 2G) you can use one of the newer sim cards. To Identify whether your sim is the newer variant with no registration restriction look at the back where the gold contacts are, if its a newer sim it will say in small lettering "TMXXXX" (where X is a number, ie TM4322) and it will also have an expiration date printed (it must be activated by this date or it becomes unusable.)
In terms of 2G/3G the sim card itself and its age should not make a difference as the capability to connect to those networks is dependent on the phone, not the sim. You can think of a sim card as a gateway that connects your phone to the billing system and authenticates it.
Having had said that, if you are having connection issues it could just be a defective sim card, to check, just place the sim in a phone that isn't having any connectivity problems, if it starts having problems, replace your sim.
In terms of the digit you highlighted in that picture, I believe it has to do with the manufacture year, although if I remember correctly its digits 4 and 5 that make up that information, but otherwise isn't anything important to a consumer.
well i got curious and checked ....i have the bigger sim ...i don't think the numbers matter much

That's what I thought...until a lot of people started noticing better 3g connection/speeds with the new sim cards. Just a placebo effect perhaps?
The size difference could also be for users who want to make it a micro sim so they can put it in their unlocked iPhones. I don't have either of these sim cards to compare, so I'm not sure.
hmm.. the sim im using is almost 8 years old. its been moved from phone to phone so many times there are wear marks on the contacts. still works fine though.
When I first got my g1 a few years ago I had issues with the market. There were apps that I knew were available (private apps) but I could not download them. I went to a T-Mobile store and looked at the display phones. One of them was able to see private apps, the other like mine, could not. I talked it over with the rep and we decided to replace the sim card. It was a random, no other ideas, decision. Started the G1 back up and Market was now working as expected. There were no other benefits noticed. Since then, I tend to replace the sim anytime a new phone is purchased.
Your milage may vary.

When I got my Vibrant, coming from the g1, tmo wanted to just pop it in the Vibrant. I made them put in the new sim card just to be safe, figured the one that came in the box brand new SHOULD be better.

Its only on the newer ones, the old ones don't expire, they just stop working after a set number of registrations on the network.
In regards to sim issues, they really shouldn't have any impact at all. Changing a sim card refreshes the billing information in the system (like what kind of services your phone is supposed to have and what not) customer care can do this without the need for a new sim.
Hoenstly though, sometimes a sim replacement is needed, I've seen stranger things.

When I bought my phone out right, the rep opened the box and took out the SIM then sold me the phone.
I guess it doesn't matter since swapping out your SIM at the T-Mobile corporate stores is free.
I just tried this since there is a tmobile store across from where I work. I used SpeedTest app and ran it 3 times before the swap. Average was about 2500 kbps download and 300 up. I swapped the sim out, went back to the spot where I originally tested and ran three more times and got about the same rate with the new sim. My old one was about 3 yo from when I had my Dash.

I'm thinking the only time one would see a difference is if they are having poor contact surface from the SIM wearing out. I've seen ooolld SIM's where the metal had indentations like no other.
Just read the thread and said why not had the same sim card since I first signed up with tmobile 5 years ago.
When I talked with the rep on the phone and explained this to him and asked could this help he stated that the official tmobile policy is if the old sim card works no need to switch. However, because of the technical specs on the card could cause better reception, they just can't guarantee it, they only guarantee it will not get worse. He asked if I was having issues and I said no i'm just a nerd and wanted to know if it would help. Just swapped it out going to give it a test around the house and will report back.
Back Story:
Upgraded from G1, perfect 3G everywhere in chicago, couldn't even get it to drop from 3G no matter where I went. With the Vibrant and and old sim card, constantly dropped to 2G no big deal still was speedy
New Sim Card:
will report after testing
Old Sim Card
My connection constantly jumped from 2G to 3G all over my house constantly
New Sim Card
Solid 3G all through the house, will report back after tomorrow when I travel all over chicago
I am traveling to Jamaica, and I would like to disable data but still allow voice and sms. I know switching to airplane mode will disable all sms/voice/data.
Even for voice, make sure your aware of the international charges. ATT (and cell phone providers in general) are notorious with hitting you for insanely high bills when traveling internationally.
Their reps are also often wrong (if something sounds to good to be true, ask for it in writing) - for example my nephew believed it when they told him that he wouldn't be charged for receiving SMS/Emails overseas as long as he didn't open and read them. That was a flat out lie, and my sister had to pay the bill.
Personally, I always pop out my SIM card when traveling overseas and replace it with a Prepaid International SIM card, though purchasing one locally works as well. A number of such plans will disallow all data access.
Edit: Note that to use a prepaid SIM card, you need to SIM unlock the phone first. As long as you've been an ATT customer sufficiently long, they will give you the code if you call customer service and state that you'll be travelling overseas and need to use a local SIM card.
From a bill-paying standpoint, unfortunately no. ATT requires the device (and any smartphones in general) to have a monthly data plan in order to be active.
From a end user stand point: Menu>settings>data manager>data delivery>uncheck data enabled.
This will essentially turn off your data connectivity but you will still be charge the monthly fee.
work around: call att's customer care (611 from your mobile device) and have them perform an IMEI swap. You give them the info for an older device you have lying around that does not require data or a go phone. then remove your data feature from the account. Last step: keep that sim in the atrix and have voice/sms minus the data.
hope this helps

If data roaming is disabled, no data should be used. It is disabled an many phones by default. I had several Android phones and I travel at least twice a year to Europe and I never had any data charges. If you want to be 200% sure, you can disable data completely, then follow bl4ck0ut recommendation.
"As long as you've been an ATT customer sufficiently long, they will give you the code if you call customer service and state that you'll be travelling overseas and need to use a local SIM card."
That WAS the policy but according to the AT&T rep I spoke to yesterday, that has been modified. Customers with new phones (newly released phones, such as the Atrix) will not be given an unlock code until ONE YEAR after the phones' release date.
That's just not right, if they're going to modify their terms, they should say that up front.
I have been digging through the threads and it gets confusing with different people referring to unlocked tablets that are overseas etc.
I have a tmobile US springboard that is running the most recent rooted mediapad rom from this board (it runs great btw).
I was hoping I could use this device as my phone. I rarely take voice calls on the phone. I have Bluetooth in my car which is really the only place I talk to anyone and I have a Bluetooth headset if I need it. Most of the time I send texts and use data.
The problem is that when I put my phone sim card in the tablet, phone and sms work fine but data stops working (more specifically, it redirects to my.tmobile.com). From what I have read, I think we are just going to have to deal with it for now but I wanted to see if there are any options because some people thought that removing the imei file would help. There is also some stuff about data in the build.prop for the device.
How about getting a device subsidy unlock code from t-mobile? I should be eligible.
IMEI unlock
I copy and paste tmobile policy as blow:
support.t-mobile.com/docs/DOC-1588
" For information on the SIM Unlock Code, refer to the following:
If you purchased a device from T-Mobile, it has been programmed with a SIM lock which will prevent the phone from operating with other compatible wireless telephone carrier’s services. If you wish to use the phone with the service of another wireless telephone carrier, you must enter a numeric SIM Unlock Code to unlock the phone.
If you have a Postpaid Plan, T-Mobile will provide the SIM Unlock Code upon request to eligible customers, provided the requesting customer has a minimum of 40 days of active service with T-Mobile and did not request a Subsidy unlock code in the last 90 days.
For customers with a Prepaid Plan, T-Mobile will provide the SIM Unlock Code upon request to eligible customers, provided the requesting customer has a minimum of 60 days of active service with T-Mobile and either a Prepaid Plan account balance of at least $10.00 or a prior refill within the last 30 days.
T-Mobile will provide the SIM Unlock Code upon request to eligible former customers, provided that T-Mobile has such code or can obtain it from the manufacturer.
If you paid full retail price for a device, you qualify to have the SIM subsidy unlock code providedif you meet the following requirements:
The device must have been purchased at a T-Mobile retail store or authorized T-Mobile retailer.
The device must be paid for completely. You must be able to fax the proof of purchase to T-Mobile."
As indicated if the device is paid for completely, we qualify to have the unlock code. Have you or anyone tried to get an unlock code and tested?
I bought a Springboard on ebay and signed up for prepaid data for 60 days with tmobile after which time I requested a SIM unlock. I received the unlock code and after inserting my AT&T sim I'm able to make calls , get data, and text.
I can't specifically verify which bands on ATT nor whether I am getting real 3G data. I can verify that I am able to talk, text, get data.

If you're able to get more than 384kbps then you've got HSDPA/HSUPA/HSPA or whatever (real 3G is 384kbps). On most country, the signal label would change to H, on T-Mobile it would probably change to 4G. I can't exactly verify the label change though, since I'm on a data plan with 3G only speed (so my top speed is 384kbps).
If you can't trust the label then use those speed test app and verify it yourself.

I have a question: Since your device has updated firmware (mine is running ICS), does it mean it has been unlocked already? Have you tried a SIM from another carrier? In another word, will updating to a generic firmware unlock tablet automatically? My reasoning is that all the coding/decoding is through software and an updated generic firmware removes all the T-mobile stuff as far as I can tell. The software that is in charge of sim lock is very likely been replaced as well. My doubt is that people can then buy a Springboard with data contract at a much lower price and update the firmware to remove the lock. I bet T-mobile is smart enough not to let that happen.
I finally got the unlock code from T-mobile and bought an ATT sim card. Unlock is not that as simple as I thought to be. Strangely, my ICS does not pop up the unlock code entering interface. I cannot remember from which post I downloaded the ICS. It is within "the" giant thread. By using the famous ()()2846579()()=, it showed nothing after "SIM card lock state". So I flash back to HC3.2 and unlock the device in the pop up interface. After flashing again to the most recent general firmware from huaweidevice.com, it shows "SIMLOCK_DEACTIVE" after "SIM card lock state". Recalling the sim card lock status is one of the features installed after a second boot during the installation and I did not recall my first ICS did that, I am wondering if the first ICS does not install the component related to sim card lock status. Probably my springboard under first ICS is unlocked by software.
Anyway, I am pretty happy with the latest version and have an officially unlocked springboard. From this experience I learned that SIM card lock status in general does not change after update the firmware (at least the official one). And probably someone can do it by modifying the firmware by his/her own.
By the way the ICS I first had has no fastboot option.

I am thinking of unlocking too and I am wondering where you found the HC3.2 to flash? I searched the forum and the only one I found appeared to be made up of many smaller files. There appeared to be multiple versions of files and I was not sure which ones I needed and how to flash them.
If you only want to unlock, flash the latest ics for general purpose from Huawei. The unlock interface appears after you insert a sim card other than tmobile.

Hi!
Rooted with cmahendra's offline Lelus method (and to anyone who's done that, my hat is off to you).
**SHORT VERSION**
Sim goes into the L9. I get bars that show network availability, however I am not able to connect/make/receive phone calls.
**DETAILED VERSION**
Starts like this: I have my CM rooted Aria that works a-ok as far as the network. Phone message memory getting full all the time and incoming texts bounce back, with no way of knowing who sent them. Can't have that, so I buy a stock L9.
Sim works. I want to have Wi-Fi calling, which is the *only* reason I bought the L9. Wi-fi calling is not working: call up T-Mo and they say I need to give a 911 address and all will be well. Ok, done.
Sim works. But no Wi-Fi calling still. Call up T-Mo and they say "Ohhh! you need a "3G-B" (I don't think that stands for gigabyte) sim card" Ohhh and what's your phone model etc etc. I tell them "it's a no-brand phone I got overseas," they don't need to know the model: they didn't with the CM Aria. They're clicking settings on their screen other side of the phone while we're talking: I can feel it.
Sim *stops* working. Need a working phone, so let L9 aside and get a stock T-mo S2. Same issue, cell network not connecting.
Let me show THEM! Ha! I'll unlock it. Unlocked the S2.
Sim still doesn't work.
Put the Sim back in the rooted/unlocked Aria? Network works.
What settings do they have in their stock phones that disallow network connectivity, because in the CyanogenMod Aria I have the phone fully works, GPS, tether, etc etc. In their stock-from-T-Mobile phones, network = nada.
Thank you for reading.

What the heck are you asking? I don't see any understandable questions in your message. I see you blowing off steam.
It does look like T-Mobile cooked your sim. You may need a new one.
Call them again and ask for "Customer Retention" through the automated system. Those people are more knowledgeable. A new sim should be free if they killed it.
Also, a data plan is not required for wifi-calling.
T-Mobile will give you a SIM regardless. They are always free.
I'm not sure as I am unrooted, but most carriers block network access via files in the EFS folder. This folder is VERY delicate. Anything improperly changed here can render a phone useless. If the SIM works in another device, it's not the SIM. Have you tried a different SIM in your phone?
Also, if you're blocked from network access, when you make a call, you should be prompted with, "We're sorry, but this device has been blocked from network access." If you do not get that prompt, then there is something wrong with the phone itself, be it software or hardware.
Looks like the L9 isn't registering in their system. Where did you buy the phone, blacklisted perhaps?
As for fried your sim, why does it still work in the Aria.
As for 3G-B, you probably need a newer sim, others call it a 4G sim... They should send you one free or pick one up free at a local tmo..
Thanks so far folks...

You hit the nail on the head exactly clockcycle, it's not registering. Something *in* the phone is not letting it connect, because my sim works successfully in any and every other unlocked phone I have, blackberrys, GMS world phones, the rooted Aria, but in the two "newer-released phones-- the L9 and the S2-- it doesn't work.
Phones are legit. Craigslist and brand new. Worked perfectly until calling T-Mobile for "support". The sim is fine and the goal is to keep it and not get a new one. It works.
My strong guess is that if I put a different rom that is *not* stock, the phone will work fine. It worked fine in the beginning, until I called them to address the wi-fi calling issue and they started poking around in my account, asking questions and clicking on things. I didn't want to address the wifi-calling issue too much because we could go off on a tangent.
You're right kevev, it didn't look like there was a 100% clear question. A lot of story though, to make sure there aren't 50 posts of did you do this and id you do that. A full story gives everyone the most info they need to understand the situation instead of "yo! my phone is not connecting!" which we see sometimes .
So the more clear question is:
"I am experiencing carrier settings *in* my L9 that are blocking me from connecting fully to the network on a perfectly fine sim card, how can I get around these settings and what/where are they."
I think tribalartgod understands what I'm getting at most completely. The inside-the-phone-settings. When the sim is in the phone I have bars, but when going to make a call the screen message is "emegency only". Can't try different sims in the L9 because of the need to cut the sim down. Also the L9 is not unlocked, just rooted. My guess is a de-bloatwared rom is the fix. Looking for answers from people more knowledgeable than me which is most likely all of you. Thanks again!
Craigslist, new, boxed, doesn't gurranty they aren't blacklisted.
BUT, the Aria uses a miniSim, the L9 uses a microSim. Did you cut your Sim yourself? It might be misaligned, cut wrong.
It's less than $2 to get it unlocked..
It sounds like its IMEI blocked dude. This can happen with various insurance or installment plan scams, even to brand new devices. There are options to still use the phone, but you are hosed on T-mobile. I have a blacklisted L9 because the previous owner quit paying his EIP, but it's unlocked so I used it on an AT&T MVNO connected to an AT&T MicroCell (I wanted WiFi calling too, but that won't happen with a blacklisted IMEI). Until you've gone to T-Mobile's chat support and ask the if the IMEI is clean, writing long posts in this thread is futile, and it is pretty clear everybody in this thread THINKS they know what they are talking about, but nobody has simply asked T-Mobile about the status of the IMEI, which takes two seconds.
Hello.
I have a network locked S6 that I used it for 2 years by being unlocked with root at a gsm service.
One day I installed a Spotify apk virus not knowing where to look for the real deal and it reset the IMEI to 35000000000006, making the phone stop recognizing any SIM, yet the apk worked as expected providing full non stop play.
I was in the middle of the pandemic with nowhere to go with the phone so I researched and learned how to re-rewrite the original IMEI with z3x, which I successfully managed to do, the phone now seeing when a SIM is inserted. I also installed the latest firmware that was available for this model from this network provider - June 2018, before was April 2018. Trouble is that the initial unlock method have gone and the phone is again network locked.
I have tried to unlock it with z3x with no success, different steps with custom-rom etc so I decided to order the codes online.
I received 2 codes, the unlocking code and PUK code, both valid. Upon reboot if I insert any of them it says that the code is invalid after which at a second attempt it says network unlock successful. The same behavior happens if I try only with the main code or PUK code, but the problem is that the phone remains network locked even after restart, requesting the code again.
I have tried #7465625*638*# and then enter the codes in different order multiple times as advised by the seller yet the same, network unlock successful except that phone is still locked. The phone is in stock mode after a factory reset and I'm out of options google being unhelpful on the matter.
Question is, did I did anything wrong with z3x, damaging something? If so, what and how to repair? Is there any other option to make the phone fit for purpose again, to be used as a phone?
No responses
Today I found out that by typing any code, random numbers, it falsely says 'network unlock successful' at the second attempt so the original codes were of no use so far. I don't know what I'm looking at, what type of files to reset/replace or what to do. ANY advice will be appreciated...

ROFL
My knowledge is that a network lock ( also known as SIM lock, simlock, or subsidy lock ), is a technology that wireless communications carriers use to prevent the mobile phones they sell from being used on another network. Cell phones can be locked to a particular country, network, or subscriber identity module (SIM) card.
A network lock has really nothing to do with phone's IMEI, it's SIM-card related, believe it or not.
FYI: On phone's Android exists /EFS partition where among other things the Network Unlock information is stored. If this /EFS gets corrupted or even deleted then you will not be able to make or receive calls, SMS, MMS, etc.pp.
It's not me who is the idiot here: I'm sure of it.

Oh boy. Where did I said that the IMEI have anything to do with network lock? I just presented the full history of the device, on what type of troubleshooting went thru to learn if the steps taken to solve previous problems somehow interfered with network lock, namely repairing the IMEI with its specific NV data file and flashing the latest firmware, nothing more.
Because the original unlock codes are not positively registered and even more, it says that is unlocked on random codes despite is not, this wasn't a google-able solution. I thought coming to the largest site of android&phones dissection would at least earn me an advice, a method, something...
FYI: As already stated, before the IMEI+firmware intervention the phone was unlocked professionally at a gsm service with root, this is all I know, method that went poof after the intervention. The phone is not blacklisted, works with the original carrier which I have no interest in using so no network data is damaged except that it doesn't unlock by the recommended method that always works - original codes, instead is displaying a false positive.
