Hey all.. I just got my unlocked G2 to work on my local carrier's 3G. Im from the Philippines which only supports Band I (2100) UMTS. Turned out that my old sim wasn't 3G ready/activated and I wasnt able to connect to the 3G network before. Bought a newer sim, inputted the right APN settings and I was good to go. Now I can browse and access the internet/market on my phone wherever I go.
The G2 is indeed an international device. Thanks for all the help.
Hi all,
I am desperately looking for a solution to the above problem.
Background: I moved about a year ago from Germany to Canada. My HD2 worked well with the sim card from Telefonica/O2 on the network over here. The phone itself is not locked but branded. Anyway when I tried to change to a Bell sim card it did not want to work. So I looked up the frequencies. My HD2 works on the following frequencies:
GSM1800
GSM1900
GSM850
GSM900
W-CDMA(UMTS)
The providers over here have the following frequencies:
Telus (including Koodo)
2G
CDMA 850/1900
EVDO 850/1900
3G (and fake 4G)
HSDPA 850/1900
HSPA+ 850/1900
UMTS 850/1900
WCDMA 850/1900
1x EV-DO CDMA2000
Bell (including Virgin Mobile, PC Mobility)
2G
CDMA 850/1900
EVDO 850/1900
3G (and fake 4G)
HSDPA 850/1900
HSPA+ 850/1900
UMTS 850/1900
WCDMA 850/1900
1x EV-DO CDMA2000
Rogers (including Fido, Petro-Canada Mobility)
2G
GSM 850/1900
GPRS 850/1900
EDGE 850/1900
3G (and fake 4G)
HSDPA 850/1900
HSPA+ 850/1900
UMTS 850/1900
WCDMA 850/1900
I thought at least that with the frequencies like CDMA and GMS matching I could use any provider that works with these frequencies. Obviously I was wrong there Anyway I want to use the phone. Can anyone out there help me and get me the information which provider would work with the phone? I would use anyone as long as I can just use my HD2 again.
Thanks so much for any kind of help.

EU HD2 will work on gsm in Canada but looks like will not match 3G wcdma used in Canada.
I used my EU HD2 in Canada on Rogers for a week & was fine on gsm.
Do check in phone settings to see bands are set to auto or gsm only, if set to wcdma only then will not connect to anything.
Not much you can do on 3G issue as hardware & not changeable, the australian Telstra HD2 & USA T-Mobile Hd2 is more compatible as hardware supports the 850,1900 & 2100 wcdma bands ....

Thanks Mister B
I was with my German sim card also on Rogers. I just did not know if the phone would also be able to handle the local sim card. I will try Petro Canada or Fido. Rogers is a little expensive. Anyway thanks. Gives me hope

Hey all,
I just wanted to give a feedback on my recent experience. I yesterday checked at a Fido shop and I can confirm that it works. I now can use my HD2 again :good::victory::victory::victory::good:
I will get a sim card next weekend and then will see how to update my phone to something more current.
Thanks again for the tip Mister B

I was wondering if anyone has successfully flashed an AT&T rom to another carriers device, specifically a Verizon galaxy s4. I was told to try it but I wanted to know if it's been done before.
Is the bootloader on your s4 unlocked?

No it is not.
That's good. However, flashing an i337 ROM onto your phone may result in a hard brick. I don't know about the partition layouts on i337 vs version s4.
With an s3, cross-flashing custom ROMs from an international s3 to a North American s3 will hard brick the North American s3.

I think mine is an international version. How would confirm if it is or not?
Is the Verizon s4 a cdma phone with an 3g/LTE sim slot? Flashing an AT&T ROM to your phone may disable phone calls and data as the AT&T ROM requires a specific bootloader and radio frequencies to work. It could also hard brick the phone.
If I were in your position, I would find out how to flash a custom ROM before attempting to flash the AT&T ROM.
Any particular reason you want/need the AT&T ROM?

My phone has CDMA and GSM network settings. I am using this phone on AT&T because I cannot afford to buy a new one right now. Everything works except sending sms on a LTE signal. Fails every time. If I switch to HSPA+ I can send sms but being on this signal causes my battery to drain really quickly for some reason. So I'm trying to sms to work properly on a LTE signal. Someone suggested I try flashing a AT&T rom to my phone since it would most likely have the correct sms files which he believes is why sms doesn't work properly while on a LTE signal.
I understand. Are the APN settings the same for 3g and LTE?

Yes they are
I did a quick search and found this:
Does your mobile web work? mms uses mobile data and standard text messages do not. I have had mobile data take up to 2 days to work on a new activation you stated you took the apn settings off the att site but I just thought I would post what is on my phone just in case it may be different
Name: ATTPhone
apn: Phone
mmsc:http://mmsc.mobile.att.net
Multimedia message proxy: proxy.mobile.att.net
Multimedia message Port: 80
mcc:310
mnc:410
apn type: default:mms:hipri
both standard and roaming protacols are ipv4
everything else is not set also try turning mobile data off then back on.
also make sure that the phone is in global mode

Yeah everything works except send sms. I can receive sms all day but it fails to send. I can send and receive mms, make and receive calls and browse the web. It's just send a standard text message fails every time. Those are the same APN settings I have currently. And it's not a new activation. I've been trying to figure out a solution to this for about a month.
international version has better roms than any other carrier ....... am using an s4 att version with international carhdrom 4.4.2
Verizon S4 on At&t

The reason it isn't working on LTE is because the Verizon S4 only supports 2 LTE bands and does not have all the LTE bands needed for the AT&T network. There is no way for you to use the LTE network fully and get SMS to work. This is a hardware limitation.
US GSM (AT&T - Model: SGH-I337):
GSM/EDGE: 850/900/1900/1800 MHz
UMTS/HSPA+: 850/1900/2100 MHz
LTE: 700/850/1700/2100/2600 MHz
US CDMA (Verizon - Model: SCH-I545)
CDMA EV-DO Rev. A and Rev. B: 800/1900 MHz
GSM/EDGE: 850/900/1800/1900 MHz
UMTS/HSPA+: 850/900/1900/2100
LTE: 700/1700 MHz (Bands 4, 13)
I have not personally needed to do this, but you can modify your "SMSC" preferred network type from "LTE/GSM" to "GSM Auto" which should route all your SMS messages through HSPA+ instead of LTE. Therefore, you can use your phone on LTE (calls/data) like normal but the SMS will be HSPA+.
Root device if you arent.
Install Advanced Signal Status
Hit "Additional Info" in the app and then "Phone information".
Change dropdown for "Set preferred network type:" to "GSM Auto".
You can hit "Refresh" button and it should show "+13123149810" for AT&T otherwise change it to that for AT&T.
Restart phone.
Hopefully that works!

Actually I can activate all the LTE bands through one of the hidden menus. But when I do it still doesn't work.

That is because the Verizon S4 itself, hardware wise, does not support all the bands AT&T uses (like band 17). There is nothing you can do to make your phone work on network frequencies that your device doesn't support, no software can change that.
Sorry.

But in the service menu I have it shows all those bands and gives me the option in which ones to activate
XT907 on stock KitKat ROM (rooted).
I get EDGE only, no HSPA with FreedomPop GSM SIM. I've configured APN as described on their site.
https://support.freedompop.com/app/answers/detail/a_id/2670/~/activating-your-phone-gsm-sim-card
I have a good strong signal. I assume it connects to AT&T towers. Even if it were connecting to T-Mobile, I'm in a refarmed area, so I'd think HSPA should work.
Any ideas?
UPDATE: Problem solved. Needed to force UMTS in settings because it defaults to GSM.
So Ive got both my Verizon and At&t sims working however I run into a issue when selecting Verizon as my data provider.
Sim 1 is Verizon (wont allow Verizon in sim 2)
Sim 2 is At&t
Select sim 2 for data and sim one switches 2 "31000" for calls and texts only which is fine. Sim 2 (At&t) handles lte, calls and texts no problem.
Select sim 1 (Verizon) for data and sim 2 (At&t) goes into "no service". Cant make calls, texts or anything.
So basically the only way to get both sims working is to use at&t for data. Problem is my Verizon card has unlimited data. The Verizon data works perfect whether I have 1 sim in or both.
Any ideas?
It's probably because AT&T has decommissioned EDGE service in your area. SIM 2 can only be EDGE when a CDMA (Verizon) SIM is in slot 1 and is being actively used for data. With two GSM SIMs you can have 3G and LTE simultaneously...but not with one CDMA and one GSM. It's a hardware limitation I believe, though I'm not totally sure as it could be a bug too.
Check the AT&T coverage maps to see if your area requires a 3G handset...if so, then your Axon will always show No Service on the AT&T side when Verizon is being used for data.
Yep thats it. At&t shut down 2g on January 1st this year. Thank you.

Was this limitation discovered through trial and error or is it actually documented by zte someplace. The limitation about cdma/sim2 edge specifically.

ZTE is pretty tight-lipped on CDMA for the Axon 7...originally they claimed they were going to disable it altogether until it got Verizon and/or Sprint approval, which seems to have not actually happened...so they've basically said nothing about it at all, except that it's shown on the specs of the phone.
But anyway, no...ZTE has not stated there's a CDMA-use limitation on SIM 2 for EDGE only...it's just that everyone has seen this occur through anecdotal experience...and we know for sure that simultaneous 3G/LTE is possible with two GSM SIMs so it seems that there is some issue that CDMA creates where UMTS cannot be received concurrent active data use on a CDMA SIM.
A while back I tried a tmobile sim and freedompop (on att) global sim. With tmo on 2g and fp on hspa, the tmo side was constantly disconnecting (I believe we discussed this in one of the other vzw threads). I came to the conclusion that it had something to do with the actual frequencies being used by both sims. Changing the tmo setting to 3g/hspa fixed the problem - likely because it was now operating at different frequencies.
Tmobile's 2g operates at 1900 mhz.
Here in chicago att's 3g network operates on band 5 (850 mhz) and band 2 (1900 mhz).
I believe when it was switching to att 3g band 2 is when the tmo service would cut out.
Verizon's cdma operates at 850 and 1900 mhz and lte bands 2,4,13 (1900, 1700/2100/700 mhz). Att's gsm operated also at 850 and 1900 mhz. This limitation might exist then to prevent 2 different sim services from operating on the same band at the same time.
