well hello my question is r simple, i want to know if the rom CM7's post with the radio unlocked i can use for the Droid Pro, but for the European version because here we use GSM / HSDPA
Changing ROM's does not affect the frequencies that the radio uses, nor does it render your phone unlocked for use overseas.

Positive. It is more evident in the united states since we deal with carriers and different frequencies and such. My T-mobile branded phone was rooted, running CM7. If I used an AT&T sim card, it would ask for an unlock code. I got my unlock code from HTC and with an AT&T sim I am only able to use 2G speeds due to different frequencies for 3G and 4G. You can change your radio, but not the frequencies that the radio utilizes.
One quick alibi though. There are some root methods, such as the G-free method, that can sim unlock your phone.

then I can put the rom, but my problem would be the frequencies used by radio stations? there is some method to this?
It is not so much an issue for you because companies overseas use the same frequencies...you just wouldnt be able to purchase a sprint, tmobile or verizon branded phone..

ok thanks for ur help
i want to buy a d2g with a Bad ESN but i am planning to use a sim in it so i am wondering if its possible to flash it and get it to work or im just wasting my time
Will you be using the phone on Verizon? If not you should be okay
Sent from my XT894 running ICS
“Bad ESN” means the phone is blocked on VZW's CDMA network. Nothing more, nothing less.
You can use it with any GSM carrier (including AT&T and T-Mobile, provided you perform the band unlock) and any CDMA carrier that is compatible with the device (MetroPCS being at least one in the USA).

Can someone please help me with me new galaxy 3s? I just bought it from USA and i want to use it on Greece but it is locked on verizon.... What should i do?
That's an 800MHz/1900MHz CDMA phone. If Greece is like the rest of Europe and uses GSM, the phone doesn't have the radios to work there, so you can't use it. (The SIM is for data, not voice, but you need the basic connection to the network for it to work, and a CDMA phone won't connect to a GSM network.)
You should sell the phone to someone in the US (who wants a Verizon phone - it can't be "unlocked" for other carriers) and buy the GSM version of the phone.

New Verizon phones have worldwide roaming ability (including the S3) so it should work on any GSM carrier outside the US.

It is a sch i535rwb 4g phone. How can i check if it has a worldwide roaming phone? Also what should i do so that i can use it in Greece?
You need the SGH T999 (The GSM variant of the SGSIII) The Verizon variant should NOT work in Greece on a Greek carrier.

Are you sure for that? If i am not wrong this is an US version too, whats the diference and i can use sgh t999 in Greece?
I used to think it was native but apparently not. You can still enable worldwide roaming though.
Here's the thread, you need to do some hackery

You can just root it and and flash the synergy mod rom and it will work on any carrier
Does it actually have a SIM card slot or just a built in one?
If you're looking to use it primarily in your area I'd look for a different phone - sell or trade this one. I've heard the GSM can be used but that it's pretty terrible and certainly not what you'd want for a primary phone.

Got my FIDO Razr HD. Rogers SIM = all is good. AT&T sim = asks for unlock code, which i buy online.
After entering code, phone appears to do a factory reset. During the reboot, a box pops up:
"SIM not allowed MM #3"
Now the phone permits "Emergency Calls Only" with the AT&T sim. Rogers SIM = still good.
When I put AT&T sim into my other phone (HTC desire) it works fine on roaming (rogers network). So I know sim + signal is fine.
Don't understand this error message.
Did I mess up the unlock?
advice appreciated, thanks.
Do you have another Canadian SIM you can try? Bell/Telus etc?

Are the SIM cards prepaid or postpaid? Did you have to cut then yourself or were they already micro sized?

Thanks for the replies everyone. to answer the questions:
1) i don't have any other sims right now: just rogers + ATT. Next time i am w/ friends I will ask to borrow telus/bell microsim.
2) they were regular sims that were cut down.
3) haven't had a chance to visit USA since posting topic- but when i do, i will test both cards and also visit an AT&T shop to bug them about it.
Is sim corrupted? I don't think so because it works fine in HTC desire. But I guess trying a new one will prove or disprove.

I am using this phone with at&t with no problems, I took my sim out from my iphone 5 and used a adapter to go to micro sim and it works fine, no issues.
I'm receiving a Fido RAZR HD to be used with AT&T this afternoon, I'll let you guys know if there are any issues.
OOI, is AT&T seen as a much better GSM network than T-Mobile in the US?
I was looking at the T-Mo USA site, and there are some amazing "Monthly4G" SIM only plans (e.g. $30/month for 100 minutes, unlimited texts and 5GB of HSPA data).
This seems much better value than AT&T, Verizon and even Sprint! But is their network sketchy compared to the others?

AT&T offers the second largest network coverage behind Verizon. They are also one of the two GSM carriers in the United States, and tend to be more popular with mobile phone enthusiasts because their UMTS bands are more common and used with other regions such as Canada or Australia. T-Mobile does indeed offer excellent value, but they use mainly AWS band in addition to PCS band in selected regions, thus making them the lesser choice for using unlocked phones from outside the country.
Hey,
Just looking on wiki:
http://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
It looks like T-Mo mainly use 1900 for 2G and 1700 for 3G, whereas AT&T use 850 and 1900 for both 2G/3G, right?
So if I bought a Canadian Razr HD XT925 and came to the US, would I be able to use T-Mo's 3G network? I am guessing no, since it does not support 3G on 1700MHz.
But then there is a note on that Wiki page saying that they now have a roaming agreement with AT&T after the failed acquisition. So if I forced the phone into "WCDMA only" mode from the test menu, would it then fall back onto the AT&T 3G network?
Sorry for taking the thread slightly off topic
Cheers,
Su

As you have read, T-Mobile did acquire PCS bands from the failed merger with AT&T, but these bands are not as utilized as their 850 MHz band so it's not as widely available as you may think. Some areas might be able to use the 1900 MHz band for T-Mobile 3G, but I would check with fellow T-Mobile users to confirm first before you dive in headfirst. I know that there are T-Mobile users in the Dallas-Fort Worth area that are getting 3G data connectivity with their unlocked AT&T iPhones.
Well T-Mo do daily plays for like 2 bucks right, so I can always try this out before committing to a contract
Do you think AT&T would be the better bet if I am bringing my own device from Europe?
The reason I ask is that I may be coming to a US college for a couple of years, so naturally, I'm planning ahead to see if my phone will work over there

If you're using a device from Europe or Asia, then yes, you have a much higher chance of being able to get 3G connectivity with AT&T. Off the top of my head, Nokia seems to be the only one that tries to actively keep AWS band in their radios.
Hmm, so I did a bit of research on GSM Arena. Seems the Nexus line of devices consistently support 1700MHz 3G (including the Nexus S which I currently have).
Guess who cancelled their Nexus 4 order last week, and opted for a Canadian RAZR HD instead...
Whoops
I switched to sprint about 5 months ago and I got my s5 with a 2 year contract. We also got another line with another phone. The account is in good standing with payments on time always. Will Sprint unlock it for me so I can use it on a trip im taking overseas? I'm not sure what their policy is..and I know they do it OTA, so that means I have to be on stock rom right?
Yes stock rom. Sprint more than likely unlick. Of course you will have to mnew monthly charges. But depend sd wherr your going. If going to us territories sprint will work. Just call sptint anf see
They will usually unlock it for international roaming after having the phone on your account for 90 days.

please note that most of the world is now based on GSM and Sprint is a CDMA based service. Once unlocked you would probably need a GSM sim card installed in order to use the S5 (this sim card can either be one from the US, a more expensive option, or a local sim wherever you are traveling to).
In Europe, especially UK, there are many cheap GSM sim operators.

Yeah that's the plan for me to buy a local sim in that country so I can use the phone with a local number there. Do you know what bands the gsm works on?

Depending on the country involved they use 900 and 1800 mainly but the s5 has all the bands used in Europe. Note that T Mobile is a major carrier so you should be ok with this phone if it is truly unlocked
