I am using the old sim from my backflip since the new one they gave me with the atrix didn't work! Does it matter what sim you are using with 4g?
i don't believe so i'm using the one from a very old lg incite to propel pro to iphone to this phone. it displays H+ on the screen and all.
Not particularly but the reason it won't work is most likely because its parked on your account waiting to be activated. If you still have it, try giving customer care a call and having them activate it. SIM cards do change and can affect your overall service.
P.s. Call from a different phone

I've been using my 3G Sim card when I first got it. It doesn't make a difference in the speeds. AT&T has just been capping them and HSPA+ is in almost no cities.
SIM card DO make a lot more difference than most people think.. as they age they die just like all other technology, and so if you've been given a new SIM I suggest you call AT&T from a separate phone (so you don't get cut out mid conversation) and ask them to activate your new SIM.

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.

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.

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.

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 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

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.
Dear EVO 4g LTE owners,
At the moment I own a Samsung Captivate, I imported it from the USA more then a year ago. I'm actually quite fed up with it, it has a lot of speed issues and other issues like randomly turning itself off.
I really want to have an EVO 4g LTE, but since they don't sell it in my country, I'm forced to buy it through eBay. I often see phones with a bad ESN.
My question is if I can use it here for calling and data internet(we have GSM networks here)?
Can I unlock it, so I can put my own sim card in it?
Oh and will I have warranty on it?
Does anybody know if it has Dutch(Nederlands) (NO NOT DEUTSCH) language on it?
By the way; if I'd buy it, I'd flash it out of the box
The 4G LTE is CDMA and LTE, so it won't work on the GSM network in Rotterdam. Also, there is no user accessbile SIM card slot like other LTE devices, so you definitely wouldn't be able to swap out the SIM. Also, I'm pretty sure ESNs that are flagged as bad won't work on the carrier to begin with because they reported stolen or otherwise tagged as bad because of unpaid bills on the account or something. Maybe that wouldn't affect your service if you used a different carrier, but that's a moot point here, you won't be able to use this phone on any other carrier to begin with.
The LTE doesn't have a SIM slot that would allow you to use it on a GSM network. The only SIM that it has is embedded and inaccessible without taking the phone apart and even then, I don't think it's as simple as just popping yours in.
Edit: ^Beat me to it.

Thanks for replying,
Hmm I didn't read the specs well on PA I see. My network (Tele 2) provides LTE, but only in the Amsterdam area...
It won't work. It is designed to work on Sprint towers exclusively.
I have seen options to have it work on other US networks(boost, cricket, etc). Not for anything international though.
Consider a HTC One X as the exact same option.
Good luck.
Look for an International HTC One X in your area. Same phone, different look.

ESN dummy, really need help.
I'm getting a great deal on eBay for a Galaxy S5 on Sprint. It has a clean ESN, I checked it, however I dont know if the phone is unlocked. Will I be able to pop in an Indian GSM sim card into the phone and use it without any restriction?
If you have any skill flashing phones [and have a donor phone], I would recommend flashing the bad esn Evo 4g LTE to PagePlus. That's what I did.
I acheived 3g data too, though that part was hard.
If you're interested in this, let me know and I can try to post some of the guides/links I used [I used several].

I didn't have another sim card, but I'm pretty sure you activate his line first, then switch out the sims. I activated mine on my other line, and the sim card was attached to that line.
OK. Thank you. That will work then right. Just swaping sims to regain each others current phone number?

I never had a 4g phone before, so they sent me a 4g sim. When i activated the sim, it was on the other line so the sim was "attached" to that number. You can go online and switch it, but there has to be a 24hr wait period (give or take.) So I didn't want to wait a day to use my phone, so i went to a third party VZW reseller and got a new 4g sim and activated it there onto my line. The phone, I believe, initially has to be activated on the upgraded line first. Many people have said they have gotten the phones and put in their sim right away and that has worked as well.
I recently upgraded to an HTC One, but don't want to sell or give up my beloved Atrix 4G. I know I can use the microSIM from the One with an adapter in the 4G, but I've read horror stories about ruining the contacts, sim card tray, phone, etc., etc.
Does anyone have a link to a known adapter that will work without damaging the Atrix? One person said they use a microSIM without an adapter. Is that possible? I can't just get a new SIM from AT&T as the old SIM was deactivated and they won't issue a new one for the same phone number, even if both phones are not being used at the same time. I want to be able to use the Atrix on the weekends. Any recommendations will be appreciated.
Well the atrix manual says not to use adapters, so maybe get a new sim. just trying to help
