I bought a new att 8525 about a month ago it came with an ATT 3G sim card
I have a Thailand phone and SIM card(the network is AIS)with international roaming. Before I bought the 8525 when i would be in the U.S., I would just use my thai cellphone, an old tri- band nokia and when in the states It would automatically conect to Tmobiles' gsm network(1900 frequency I think)
On the 8525, The phone was locked of course so that the thai sim would not work. I ran Pof's program Auto unlock v3a. I put the AIS sim back in the phone and it worked and automatically conected on Tmobile's gsm network . I was exstatic!!!
Then... I caught a plane back to thailand. While between planes in Taipei I turned on my phone with the Thai sim and it connected !!! I was still exstatic!!!
THEN...I landed in Bangkok thailand. Turned my phone on and it will not recognize any netwoks other than some weird 1900 gsm network that I have never heard of. It does not recognize either AIS or DTAC or Orange which are the big three in Thailand.
I took my Thai sim out of the 8525 and put it back in my old nokia phone and it immediately conected to the AIS gsm network.
So it appears my new 8525 phone is not recognizing 900 and 1800 gsm networks. Pof's program definately ulocked the sim because it doesnt ask for an unlock code. I read the NO gsm issue but I am not sure that is this issue because the phone does appear to recognize 1900 gsm both here and remember it did conect to Tmobile 's 1900 gsm network in the states.
So the issue is recognition of 900 and 1800 gsm.
What can I do? Can someone please help?
Thank you in advance
Here are my device info after runing pof program, I am not sure what the info was before I ran the program:
ROM version: 2.15.502.3
ROM date: 04/09/07
Radio version: 1.16.00.00
Protocol version: 32.53.7018.01H

Have you checked to see what is enabled under the bands tab in the Settings > Phone panel?
Possibly, something is disabled there. It is possible that you have a resricted setting. If you do not have the "Band" tab visible, the registry hack is in the wiki or certainly somewhere. Try the google search link in my signature.
registry tweaked to add band tab but still havea problem
Thanks for the advice.Sure enough the band tab was not visible so I tweaked the registry to ad the band tab.
However when I try to change the gsm band from"auto" to 900/1800 I get a messsage that says :
"Warning unable to change gsm/umts band, please try again later."
regardless ofhow band setting are changed, auto./gsm, my phone still only detects the 1900 gsm band. arrrgh!
I have since my last post also updated my radio to 1.50,still nothing.
any elpis gretaly appreciated.

"Warning unable to change gsm/umts band, please try again later."
This ussually means there's a live connection somewhere. Make sure your disconnected from gprs, internet, etc., then your manual band changes will take.
thank to everyone that makes this forum possible
Problem solved after i shut down the phone, inserted my att sim, then phone all of a sudden starting recognizing all the 900/1800 networks here(asia/thailand). I then shut off the phone, inserted my thai ais sim and it also started picking up the networks. Not sure why I was geting the warning message .If it is due to having a live conection somewhere, my gprs was not configured on the new phone yet for thai/ais simand would not connect.
Anyway thanks you all for this forum.Now I will read , read read some more on the best 6.0 ROM for my phone.

Vodafone requires that a new Access Point Name (APN) be set up for the SIM. The problem is that the Photon won't let me me create and save a new APN. What I've discovered is that, if I set the MCC and MNC in the APN to Sprint's values (310 and 120), then I can save the newly created APN, but the data connection won't work. If I set them to the appropriate values for Vodafone (505 and 03) then press save, the newly created APN disappears.
I spoke with Sprint today, and after 40 minutes of getting bounced around, finally got to someone who told me that this was by design. So if true, it appears that the SIM is unlocked for voice but locked for data (at least, if the carrier requires specific APN settings, as Vodafone does).
I also tried using APN Manager from the Android app store to create and select a different APN - no dice there, either.
Any suggestions, or am I out of luck?
The good news is that I brought my trusty old Touch Pro2 with me, just in case, and it is working fine ... but going back to the TP2 after a blissful week of using the Photon is really, really hard.
Doesn't make sense to me that it would only be unlocked for voice and not data. Did you try contacting Motorola directly? I'll rather hear it from the horse's mouth.
It's hard to tell who's really the horse in these situations ... nonetheless that is a great suggestion, and I've just submitted the question to Motorola's support site.
Im sorry...im very confused by this. Ill be traveling to lebanon tomorrow and specifically got this phone to be able to pop a sim in and use data and voice....your saying i wont be able to uze data?

I am saying that I can't use data ... your experience may be different. I suspect that this may work for some carriers but not for others, depending on what settings they require for data. If they require you to create a new Access Point Name profile, then it most likely won't work, given my experience.
I'm able to use data on a foreign sim. I was able to save the apn also. This is with Telcel and Movistar in Mexico. Setup the same as my Samsung Captivate.
So is there any possibility that this thing would ever be unlocked for US gsm networks like the Touch Pro 2 was? That would make this unit epic....

Which carrier did you purchase the phone from - was it Sprint?
So here is the latest, for anyone who's interested.
I emailed Motorola asking about why I couldn't save the APN, and was told
Motorola does not have any access to the Access Point Name (APN).The APN can only be access or generated from the service provider.
I then contacted Sprint again, and got a hold of someone who took my request more seriously then the previous Sprint people. After several days, however, this person came back with
I contacted Motorola and was told that the data will not work with the Motorola photon gprs data
I have no idea what the truth really is, but the bottom line is that I could not get the phone to work with data using a Vodafone Australia SIM. I even had Vodafone replace the SIM with their most current SIM - didn't help.
My Touch Pro2, on the other hand, had no problem getting the SIM to work for both data and voice, and I ended up turning my TP2 into a wireless router so I could indirectly use my Photon while out and about.

It's been a while since I was in Australia, but if I'm not mistaken, Vodaphone operates data on UMTS 2100 down under. The photon is tri-band, not quad-band, so you're not going to get data with a Vodaphone AUS sim. Virgin Mobile in AUS operates their 3G network on 2100 AND 900 MHz, so that would be an option. Another one would be Telstra. A SIM from either of those providers should work, giving you access to the APN settings. They remain grayed out until the SIM can register with a UMTS data circuit on the required radio band.

It depends on where he is in Australia. In most areas Vodaphone's network operates on UMTS2100 which the Photon does support. In some smaller areas it's UMTS900 which the Photon doesn't support.
Is it possible that the SIM card is supposed to "provision" your data similar to when you activate the phone on the Sprint network initially?
Or is the creating of an APN always a manual program effort by the user?

This is a good point. It's entirely possible he's in a UMTS900 zone...

This is from Motorola's site:
NETWORKS4
Worldphone - WiMAX 2500, CDMA 800/1900, WCDMA 850/1900/2100, GSM 850/900/1800/1900
I believe WCDMA 2100 is the UMTS band being referred to. I am fairly certain the Photon is a Quad-band true world phone. http://www.motorola.com/Consumers/U...Mobile-Phones/ci.MOTOROLA-PHOTON-4G-US-EN.alt
EDIT: I see now you meant UMTS on 900 MHz rather than GSM at 900.

It sounds like the guy is having APN issues, not reception issues. Otherwise he would have at least been able to get EDGE/GPRS connections - but those too require the APN.
FYI, I was in Sydney for most of the trip, with a few days in Canberra.

I started two threads on the official Sprint Support forums. One in the normal Moto Photon, and one in the Premier area. Wonder if Sprint will respond.

Yes, it's ridiculous that Data and voice are so segmented, but these are smartphones! Gone are the days that you just had to worry about the GSM voice frequency. Now you have to make sure the data frequency and radio band are supported by your phone.
For what it's worth, I've had little luck with Vodaphone sim cards overseas. I typically use Tmobile or Orange sim cards in the UK, and TIM or Wind in Italy. For points in between, I just roam on the UK Tmobile sim. Next trip won't be for a bit, so I'm eager to see what the photon is like...
did you try rooting and manually editing the apn database with SQLite?
This was taken from the atrix APN editing thread:
Code:
2) Enable Airplane Mode
(hold power button for three seconds, select Airplane Mode)
3) Open Root Explorer
4) Navigate to: /data/data/com.android.providers.telephony/databases/
5) Click on "telephony.db"** (this should open the db using SQLite Editor)
6) Select "carriers"
7) You should see a long list of APN settings for various carriers. Edit/add what you want
8) Press back twice to close the SQLite editor and you should be back in Root Explorer. Close Root Explorer.
9) Disable Airplane Mode
So Just add the APN with the sprint MCC and MNC, then manually edit the APN's MCC and MNC and see if that works
Howzit guys,
I brought a HTC Aria in the USA on AT&T network. I came back to SA and rooted my phone put Android v2.2 on (phone came with v2.1) thinking that would unlock the phone, but it didn't. I ended up looking on the net for a website that I could get an unlock code for my phone. Long story short, I found one, paid for it and it worked. I'm using the phone on Vodacom no matter what I do I can't get 3G or HSDPA to work, only GPRS. HSDPA and 3G work fine in the states.
After doing some research I noticed that in the Mobile Network settings on the phone there is 3 options under Network Mode:
1. WCDMA only
2. GSM only
3.GSM / WCDMA auto
Now from what I've seen I need to use WCDMA to get the 3G / HSDPA to work, but when I select option 1. I don't get any signal and then phone eventually switches to GSM automatically. I was at work on the weekend helping a customer with her laptop and she had a 8•ta 3G modem, and 8•ta 3G modems are currently running off of MTN's network I was told this by an 8•ta technician and I noticed when connecting the modem it said something regarding WCDMA.
So now my question, if I change to MTN do you think I will be able to use 3G / HSDPA on my phone?
Any info regarding this will be greatly appreciated.
Thanks
The American version of the Aria uses different 3G frequencies (because that's what AT&T uses), so unfortunately your phone will not work with 3G in South Africa. There is a different version of the Aria (called Gratia in most regions) that is the exact same phone except it supports the correct 3G frequencies for your country, but there's nothing you can do with the phone you have now to make it work.
Hello there people of XDA.
After recently getting a LG G3 Sprint (LGLS990), and doing everything i can to the cellphone i want to know if i can enable the WCDMA 900 band, ive been able to make it detect my SIM card, put in a custom ROM change the modem, but i still haven't managed to make it take data on the WCDMA band 900, if i enter the hidden menu i see "WCDMA only" and "LTE only" options for a modem settings, and changing them to "automatic" just makes them take GSM anyways, i know it takes 3G for another company which is WCDMA 850, but when i select WCDMA 900 it says "FAILED"... any suggestions? ive tried this on STOCK and BAREPOP, and to no avail..
PS: ive messed so much with NV registries i accidentally changed my ESN and MEID T_T and now i cannot change it back, ive had to enter a IMEI of an old phone i don't use anymore for it to register to my network if i can get help with that as well it would be highly appreciated (i know its illegal to change ESN but right now it has an ESN that isn't even recognized by sites and the original ESN is not blacklisted, so i promise this is nothing illegal i want to do)
Thank you for your time and patience
