Unlocked Phone APN Settings
Edited by davidbk on Dec 7, 2015 at 8:13:59 AM

Hello! I'm new to the community, and wanted to share something I recently learned: yes, unlocked phones, internation versions or domestic versions, CAN use AT&T mobile networks here in the US.

 

Some misinformation is out there, and I'd like to help get everyone connected!

 

1) If you have an "i" on the model of your phone, it means "international." That means it can be used anywhere, US, Europe, Asia, etc.  It DOES NOT mean it can only be used outside the US.  I have a Sony Xperia Pro, MK16i, I live in Virginia, and I just connected to the AT&T network. It is, however, a quad-bandwidth phone that supports 850MHz/1900MHz, which are the bandwidths used in the US. Your phone must be able to support these bandwidths to work in the US.

 

2) Unlocked phones do not have the APN settings auto-filled.  That makes sense, the manufacturer doesn't know what service provider you want to connect to!  But, here is the caveat: the service providers you call for customer support or tech support don't usually know the settings, because their phones come pre-loaded with APN settings on their in-store models. Calling them won't help you, but these numbers might:

 

Programming non-AT&T devices with the correct APN and MMS data settings

 

3) When finished, be sure to "select" this APN in the new APN list (which may only have one APN to choose).  If you are still not connected, go to your local AT&T store. See what APN settings are on their demo phones, you know, the "pre-loaded with APN settings" models, for your manufacturer. Type that data into your APN settings, exactly. I am going to create another access point with data from my local store this weekend, and see what that does!  If it works, I will share that with you, also.

 

4) check out this website for more information about international mobile network use and international cell phones:

Good luck!

A few comments:

 

-  If an AT&T customer service rep doesn't know the APN settings (or at least how to find them for you) they aren't doing their job.  There have been cases of AT&T devices that don't have the APN data properly pre-configured for whatever reason. So they need to be able to tell customers how to set it up.  AT&T explicitly does not support unlocked devices (not AT&T branded), so that is possibly the realy reason they would not give you the APN.

 

-  Keep in mind that there is a different APN for access to the LTE network.  GoPhones use yet another APN.  All are easily found by searching on these forums, or other places on the internet.

 

-  If you want/need data access on AT&T's network with an unlocked smartphone, it must be compatible with the 850 and 1900 MHZ 3G bands (not to be confused with the GSM bands).  Otherwise you will only have EDGE data speeds.  For LTE access, the phone needs to be compatible with the AWS (1700/2100 MHz) band.  When purchasing an unlocked device, its a much better idea to look at the actual phone specs to verify they are compatible with AT&T's network, rather than things like a letter in the model number, or terms like "quad band".

I tried using these settings to get my MMS to work for my GoPhone, however, the APN protocol field is not even in my options on the HTC One X. I have the data package and can get online but MMS simply will not work. I've tried several APNs and none work for MMS on my phone. Is there a separate code for phones that don't have an APN protocol field?

I'm not sure what all you have tried but instead of:

MMS port: 80

Try:

MMS port: 8080

If that doesn't work, I would go to xda developers and search there

I have a One X, and APN protocol isn't required.  

 

If you are having trouble getting MMS working, double (triple) check your typing.  One time, I was driving myself crazy with the APN settings until I realized that I had typed backslashes instead of forward slashes!

 

Also, make sure you didn't just make a new APN, but you actually need to make it the active one, as well.  On your list of APNs (you should have at least 2 now, the default "pta" LTE APN, and the new on you entered manually) make sure the circle to the right of it is colored/selected.

Thank you for this! I have followed everything that was specified but it still gives me a "Failed to connect. Try later" error.

 

My phone is an unlocked Samsung Ace II x, here are the specs:

 

http://www.gsmarena.com/samsung_galaxy_ace_ii_x_s7560m-5340.php

 

Could you please quickly look through it and tell me if it would be compatible with AT&T's prepaid network? I just have unlimited texting and 250 call minutes plan.

Most any phone has the hardware to be compatible with AT&T's 2G network (as long as it has 2G bands 850 and 1900, which most phones do).  So voice, SMS, and EDGE data should work, as long as you have the APNs right.

 

Just so you are aware, the phone you linked will not be compatible with AT&T's 3G data network (requires 3G/HSPA bands 850 and 1900, not the same as 2G bands).  But this should not affect your ability to connect via 2G/EDGE.

 

Voice and SMS should work regardless of the APN settings.  Do voice and SMS work?

I bought an unlocked Galaxy Note 3 and I'm receiving H and/or H+ instead of 3G, 4G, or LTE. I checked the configurations and everything seems right but I still don't get anything faster than H+. Is there something that I can do?

Hi,

 

My Galaxy Note II (GT-N7105) has following bandwith spec.



FDD-LTE (800/900/1800/2600MHz) + WCDMA (850/900/2100MHz) + GSM (850/900/1800/1900MHz)

 

Is this set compatible with ATT LTE network?

I have seen H and H+ symbol in this set but never seen LTE.

 

Thanks!

AT&T uses LTE  bands 4 and 17 (700 and 1700 MHz).

 

As your phone does not support these LTE frequencies, it will never be able to get LTE on these bands.

Hello,

 

I just bought an international unlocked version of LG Optimus Pro but am having hard time making it work on the at&t LTE/4G, I already took it down to the at&t store and they tried a couple of things but couldn't help, they told me that it's not built/compatale with at&t network (which I find hard to believe). So how can I configure my APN to work on my LTE/4G plan that I already have? I already tried all the APN settings listed on this page but with no luck so far except for running on E (edge). Your help is really appreciated.

 

Thanks,

 

Khalid

Why do you find that hard to believe?  There has been little or no standardization of LTE bands worldwide, and carriers have been using a wide variety of bands for LTE.  In particular, US carriers are notorious  proprietary bands to prevent the use of their phones on other networks.  AT&T uses LTE bands 4 and 17.  These bands are used in very few other places outside the US (mainly in Central America).  So its pretty safe to say, unless the phone you bought is intended to work with AT&T's network, its not going to.

 

Similar, the AT&T network uses 850 and 1900 MHz (bands 2 and 5, I believe) for HSPA (called "3G" to most, but AT&T will also call this 4G), which are also bands that are used by few other carrier in the world.

 

Also keep in mind that band compatibility is set in hardware, and therefore no amount of APN fiddling or even flashing a new radio is going to add support for a band that is not already supported by the phone.

 

Whether the model of phone you purchased is compatible with AT&T bands, I can't answer for certain without knowing the specs of your exact model.  This information is probably best obtained for the seller (although sometimes those are incorrect as well).  If the specs don't include the bands I've already stated, then it simply won't work on LTE and/or HSPA.  If the specs do include the bands, then it should work with the correct APN.  But if the phone was not specifically intended for use on AT&T's network, its unlikely this is the case (a few "international" versions do have AT&T compatibility, but this is the exception).

 

Before buying a phone for a source other than the carrier you intend to use the device on, one has to be extremely careful about doing the proper research on band compatibility.

Whether the model of phone you purchased is compatible with AT&T bands, I can't answer for certain without knowing the specs of your exact model.  This information is probably best obtained for the seller (although sometimes those are incorrect as well).  If the specs don't include the bands I've already stated, then it simply won't work on LTE and/or HSPA.  If the specs do include the bands, then it should work with the correct APN.  But if the phone was not specifically intended for use on AT&T's network, its unlikely this is the case (a few "international" versions do have AT&T compatibility, but this is the exception).

 

Before buying a phone for a source other than the carrier you intend to use the device on, one has to be extremely careful about doing the proper research on band compatibility.

ATT is using BAND 5 LTE in Bloomington/Normal IL I can confirm that. ATT is refarming spectrum because they lost some with the failed TMobile deal.

This was an outstanting post, much appreciated! The APN on my wife's phone somehow got reset when she travelled back to England, and data wasn't working upon return to the US. Called AT&T and they basically said "nope, you're all set up here on our servers, you have to call Sansumg!"

 

(sigh).

 

But in googling the question, found this post... excellent - worked immediately upon making the changes described here.

 

Thanks again!

Did your wife use a local SIM when in England?  I believe sometimes the phone will read the APN from the SIM, therefore overriding the default AT&T APN on the phone.

The Sony Xperia Z1 compact does support AT&T LTE network, I am not sure if the Honami is the same as compact model, I just bought my Z1 compact and it works with AT&T LTE network.

Is this an existing SIM (used from a former AT&T phone) or is it a new one?  If new, the account might not be provisioned properly with a data plan. Is it a post-paid or prepaid account?

Tumbler1, could you let me know your settings? I have a Xperia z1 compact also and I can't connect to lte network. I have lte on all the phones around so I know it's availability is here. I went to att & installed a new Sim card. Still only H+ on the display. My email is dgary8atcox.net. Let me know if you have any suggestions.

Thanks,

I tried using both apn settings that were posted on my HTC ONE mini but I am still seeing only 3g+ and H+ on my phone. How do I know what bands the phone is actually on. Does it use all the ones listed or only the ones where it was originally purchased? I got it on Ebay from Denmark saying it was unlocked.

You have to determine what bands the exact carrier version of your phone is specified.  Unfortunately, looking at the specs (such as sources online) for your particular phone can be confusing, as they sometimes list all the bands that might be available for a particular model, but not your actual carrier version.  I think that is what you might mean by "all the ones listed".  Does the phone packaging contain any specifications?

 

Since you have H+ (HSPA) on the phone, it seems you are looking to get LTE reception.  AT&T uses LTE bands 4 and 17 (700 and 1700 MHz).  So unless your model of phone supports those bands, you will not get LTE speeds, now matter what APN you use.  

 

Looking at the following website, the EMEA (Europe, Middle East & Asia) version of the One Mini only includes support for the 800, 1800, and 2600 MHz LTE bands.  So if this is the version you have, you are out of luck in regards to LTE.

I have 2 Windows 8  Lumina 920 phones and while I can connect to the internet with no problem and send and recieve text messages I can not send a photo with a text message.  I could not receive photos until I changed the MMS (URL) from http://mmsc.mobile.att.net  to http://mmsc.att.net .  I made this change just as a guess.   Photos also worked with http://mmsc

 

A senior ATT tech spent a patient hour with me and we got nowhere, and now we are planning a joint call to Nokia.  My phone has an Access Point set up but my wife's does not..The Access Point seems to have been inserted by ATT and can't be changed but it can be deactivated if I create another one.  We are using a WAP gateway of proxy.mobile.att.net and trying various changes in that does not seem to work.

 

Both phones are factory unlocked and we switch using them on ATT in the U.S. and Telcel in Mexico.

 

Any Ideas -
