Nokia Lumia 710 for AT&T

Hello, I am interested in getting the Lumia 710 and it seems that it has the 3G bands required to support AT&T's network WCDMA 850/1900
Has any of the new owners tried to unlock it and get AT&T's 3G?
thanks!

Wait for the HTC Titan 2 before investing in this phone...
or get a free one at walmart online... but youll have to get it unlocked since its on
T-Mobiles network resulting in only EDGE speeds

This isn't for me it's for someone else who likes the device for the design and color combinations, the device has the 850/1900 wcdma band so I was just asking if someone has already unlocked it since ebay sellers are offering the unlock code and tried geting 3G from the AT&T network once the sim card has been inserte, but thanks for your reply.

I can confirm the device works on AT&T's 3G network, I unlocked and tested Data, Calls , txts and MMS

How did you Carrier-unlock it? I have been looking into a free unlock for a while now but no luck.

you need to get the Network Setup app, turn off the device, remove sim card, factory reset the device and go to marketplace over Wifi and then go to Nokia collection, you will find it there, if it isn't there search for " NokiaNetwork Setup".
I'm not 100% sure that you need to factory reset it, try removing the sim card and restart it then try the steps above.
Let me know if it works

[Q] How to get an Unlocked One S to pick up AT&T 3G

Hopefully I'm in the right spot here, first time posting.
I just bought an unlocked (T Mobile version) One S, popped in my AT&T SIM and I'm not getting any data whatsoever. From what I had read, it should be able to use AT&T's 3G, but I'm not picking it up. Is there anything that I need to do in order to activate it or whatnot?
Many thanks in advance.

u need to setup AT&T Apn on ur phone

I'm having the same problem, I bought a second-hand device, T-Mobile Splash-Screen but using Orange (Romania). Calls/SMS work fine but no 3G. If the VPN settings are the issue, are they all the same, where could you find them and so on?

Just Google for the correct APN for your carrier.

Do this. I've tried to post the exact settings on here, but some of the information will shop up as a link, and xda won't let me post links yet. If you google it there should be an xda thread about it, that's where I got my APN info from.

Hey! Were you able to access ATT's 3G towers?

I'm using it on straight talk att and I get 4g as soon as I enter the correct apn.

Anyone using a non-AT&T 8X on AT&T?

Is anyone here using a non-AT&T branded HTC 8X on AT&T with everything working on 2G and 3G? I don't care about 4G for this particular case.
Does Voice, SMS, MMS in both directions, and data work?
Does AT&T detect it as a smartphone and require the right data plan?
Thanks.
Edit: I decided to buy both a Verizon 8X and a T-Mobile 8X to test.
After 4 days the Verizon was detected
T-Mobile one has still not been detected. Will update if it does.

I'm pretty sure you would be able to get 3G with any unlocked 8X but only certain models have LTE radios. You will probably need to add an APN to get you're Data/MMS working 100% and I at least had an issue with tethering (not sure if it is hardware or software related) but other than that you should be golden.
Although obvious, I may as well say it. It should be an unlocked phone.

I'm asking for people with personal experience because Windows Phone is such a pain with APN configuration. I have tried a couple unlocked Verizon phones but they won't work with MMS no matter what I do. There is the generic unbranded GSM version, but that one is expensive compared to the branded ones. Also people are complaining that that HTC connection setup utility is broken on the 8X so I would just really like to know if anyone has actually tested it. I don't want to get the AT&T version because they recognize that one and require a data plan and I don't want one on this line.

Yes. Voice, SMS, MMS and data worked fine. AT&T see it just fine and actually, you will probably see it listed in MyATT after you put the SIM in.
My phone is a C625a which has LTE however, an international unlocked version or a Verizon version will work but only certain models will get LTE because of the radios as mentioned above.

Is your phone a non-AT&T 8X? Or is it the AT&T branded one?
They are detecting it as an 8X?
Like my thread title says, I want to know if anyone is using a non-AT&T branded 8X. I DO NOT want them to know what phone it is because if they recognize it then they will require a "correct" smartphone data plan which I do not want.
I tried a Verizon Lumia 822 but I could not get MMS to work at all. They even removed the internet and MMS apn configuration pages built into WP8. I could use the Nokia app for setting the APN, but even with the correct MMS settings incoming MMS would not work. Outgoing would work just fine and everything else worked.
I just want to know if anyone has a non-AT&T 8X where everything on 3G works and that AT&T doesn't detect it.

3. Does AT&T detect this as a smartphone (Which will force you to have a smartphone dataplan)?

Simply using a SIM card does not mean AT&T knows what kind of phone it is. AT&T does not detect all smartphones as smartphones. They can detect all AT&T smartphones correctly and they have the ability to detect some non-AT&T smartphones, but not all. It's mostly the very popular unlocked models such as the Nexus models. Most other phones aren't in there database and just appear as unknown.
For instance they do not have the ability of detecting the ATIV S. I have one of those running on one of my lines with a $10 unlimited data plan. It doesn't support AT&T LTE, though, but that isn't an issue for the line it is on.
I would buy another ATIV S for this line, but it's too expensive at around $500. There are many 8Xs available for around $250 and I want to see if anyone is using any of those models without a correct data plan on AT&T.

Don't give up. Since you are the only one here did this. Go to your Myatt account page and see which phone is listed there for your line. If it listed as unknown or generic phone, it does not know you are using a Smartphone. If it listed as you are using a 8x, it means AT&T knows your phone is a smartphone. That's what OP wants.
As for OP, unlike WP7, WP8 lets you add data and MMS APNs easily.

I ended up buying both a Tmobile 8X and a Verizon 8X. AT&T hasn't detected either and it's been 3 days. The Tmobile one fully works and the Verizon one can't send MMS.
Verizon removed the ability to set a MMS APN manually and the HTC Connection Setup app doesn't work on the Verizon one. It works on the Tmobile one but I believe it configures the phones using the Phone APN for both Internet and MMS. You don't have access to the Phone APN unless you have a smartphone data plan, but thankfully Tmobile didn't screw around too much with the firmware and I was able to manually enter the connection information for both Internet and MMS.

That was interesting. On AT&T 8x, you have two buttons, one to add data APN and one to add MMC APN.

Yeah the T-Mobile has both Internet and MMS APN options, but on Verizon the MMS APN option was removed with the Portico update and was present but didn't work (didn't save anything) before Portico.
The Verizon Lumia 822 had both internet and MMS options pre-portico and they both saved what was entered but post-portico they were both gone. Nokia has an APN configuration app though that works post-Portico. Unfortunately even with MMS configured the 822 just won't receive MMS. When an MMS comes in it says "Message not found". Sending MMS from the 822 works fine on AT&T though.
Basically Verizon ****s up MMS so you can't fully utilize a Verizon phone on a GSM carrier.
My T-Mobile 8X mic doesn't work when set to speakerphone though so I will need to get it replaced. I found a few people online with the same issue but they found no solution other than replacement.
The 8X is such a mess.

I guess Verizon will use its CDMA network to deliver MMS. So, it is a problem for them to expose the MMS settings for GSM which may hinder the MMS on CDMA network.

[Q] Supercid carrier firmware swap m8 verizon to att

I have terrible reception and no MMS on an unlocked Verizon m8 swapped to AT&T sim. Phone is unlocked via sunshine with TWRP custom recovery and flashed to the latest Verizon firmware via http://forum.xda-developers.com/showthread.php?t=2723159 running Viperone 3.1.0 and I believe some kind of faux boot. Can I switch to AT&T firmware to get the best reception from this phone. So far I have read the hardware is all the same and was thinking I could open up the AT&T bands with this new firmware. Is there a better firmware? Can this be done on a Verizon phone? Any advice would be appreciated because I don't want to brick it and would be better safe then sorry.

If your phone does not support the at&t bands, there is likely nothing you can do about that. Also check you APN settings in phone settings, mobile networks. If they are wrong or missing, you won't be able to use data. You can google the settings for your carrier.
Good luck!

APN settings are fine have tried all of them I believe. Was wondering if I change the firmware for the phone and turn it into an AT&T phone and replace the ROM again with the Viperone ROM if that would free up the bands if the hardware is the same. If the hardware for the Verizon phone is different from the AT&T phone then I'm stuck but I'm hoping they released 1 phone with the same hardware and just put different firmwares on it so i can change the radio firmware etc.

Are u running the att viperone version or the Verizon version? I have a vzw branded m8. Running viperone. But I run the T-Mobile version so that I have a bit better call quality and I do receive all my sms mms and most my 4g antennaes. My only gripe is going between towers with 4glte on, it doesn't travel very well between towers.. So I run on wcdma only and I get my 14 gb data which is fine so that I can travel and get plenty speeds without buying another phone.

So you tried go sms pro ? That one seems to work one of the best. Also did you try google hangouts since they added support for google voice in to it ? The hangouts is supposed to work off wifi also so that could help you when on wifi at least. Did you check the at&t m8 forum for this conversion I saw another member thought they posted the conversion in the at&t forum for the m8. I have not had the time to look for myself yet.

Sprint HTC A9 Sim Unlock

Hello I have a Sprint HTC A9 that has been successful unlocked for domestic use, but I have voice with no data. I have S-Off, boot loader unlocked, running stock os. Has anyone else ran into this problem? Can someone please advise?

A friend mentioned that the Sprint variant might not have correct bands installed to be compat with other carriers. I'm wondering if replacing the radio firmware with the developer edition version would work, but I can't get around simlock to test.

HTC A9 Sprint Unlock success!!

Please share? I've been trying for days and made little progress.

There is a guy from Craigslist in my area that did it and he will not tell me, I asked. If there is any kind of way that I can back it up, screen shot it, or whatever. Someone please let me know. I don't have any personal data on it, because it has no data so I'm not using it yet. I don't care about sharing. Let me know and I'm more than happy to.

If it's an MSL code, he should have supplied that for you. I think MSL is unique to the IMEI/MEID/ESN of your device.
About your successful unlock, congrats! Your success let's me know it's do-able. I'm calling a local computer repair shop that offers unlocking services tomorrow. :fingerscrossed:

I've tried a half dozen ways to get this phone unlocked, but so far I've come up empty except for one scenario:
S-OFF
1. Change CID/MID to unlocked and flash unlocked RUU. Phone works fine, radio not functional.
2. Change CID/MID to sprint and flash sprint RUU. Phone will work with T-mobile SIM for one boot-up. As soon as phone is rebooted the SIM locks.
You can't just reflash the sprint RUU either. If you want to get another successful boot, you have to flash the unlocked RUU, then the sprint RUU and you'll get one boot. My only guess is something in the partitions is zero'd out by the unlocked RUU. I've also tried using the CM13 build immediately after the sprint RUU, and again I get one boot, but as soon as I reboot, CM13 shows sim not inserted.
Perhaps someone can make sense of this.

My HTC A9 has delivered APN setting, which cannot be modified. However, I was able to create a new APN manually and use that one. After that, data started to work. So far, I see it was able to connect to 4G and also LTE. At one place with strong LTE signal, i tested the download speed, and it was 82mbps. I have never seen that kind of download speed on my iPhone.

// , Did you unlock an HTC One A9 [Sprint] for complete LTE on T-Mobile or on AT&T?
// , Let me make sure I understand this correctly.
Can I do the following:
1. Unlock a Sprint HTC One A9.
2. Buy a data-enabled T-Mobile SIM card or AT&T SIM card.
3. Enter APN & Data settings.
4. Use that same HTC One A9 with T-Mobile or AT&T, with no loss in performance?
If this is true, that surprises and pleases me.
I assume that one can unlock an AT&T HTC One A9 for use with T-Mobile with no loss in performance, as well?

i am not sure if my experience is any different from others here. but, here's the detail of what i went through....
My Sprint variant of HTC A9 was purchased directly off htc.com back in 11/2015. Since the phone was paid in full, I believe the phone was not locked to begin with. I had been using it on Sprint for the past 10 months. Just recently i switched my plan to T-Mobile. With T-Mobile's sim, I see the phone picked up the sim card. Phone started to work (i can make/receive calls) but data would not work. I talked to a couple of HTC rep for support. Both of them told me it should work. From their understanding, A9 and the new HTC 10 should work on all US major carriers...especially mine is a CDMA phone. According to them, CDMA ones can work on GSM....but GSM would not work on CDMA network. Anyways, they were no help for me.
I started doing research on my own and found many people experiencing the same. Phone would work but data would not connect. It was not working until a member on this board, Lussardi, came to rescue. He suggested to manually put in APN. So, I started to check out the APN setting. I see with t-mobile's sim card in, the phone is using a delivered T-Mobile APN setting. I went ahead and created one myself named T-Mobile Manual. I put in APN: fast.t-mobile.com and MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc and left everything else default. After I selected to use this new APN, the phone started to pick up mobile data. Now, depending on the area that i am in, i can see it's using either 4G or LTE. At one place with strong LTE signal, i did a speed test. It was over 80mbps.
Anyways, that's all. Good luck everyone.

// , Thank you!
// , Thanks for the thorough response, and for not just giving up.
The large corporations generally don't care too much about usability for this sort of outlier customer experience.

Can you give any instructions on how you unlocked the sprint version of the HTC A9?
Thanks.
