Using on Other Carriers(GSM)

I am a n00b in the subject of unlocking phones to use on other networks etc.
Is there a possibility when the SPL is unlocked that we could use this on any GSM network since it is a 'world' capable phone with the GSM radio and a SIM card?
I have used a lot of WINMO phone son VZW and I flash and unlock quite often. Just had no idea how this process worked. sorry if this is a duplicate of any kind
thank you

You can call Verizon and ask them for the unlock code to your phone. The number is 1-800-711-8300, option 2 I believe. Either way you'll end up talking to a human who can do that for you. Then you'll enter the code (code A) in All Settings > Personal > Security. According to others, this unlock on the SIM will remain, even after flashing with a custom ROM.

no software to unlock the sim card, i don't want to call vz

I can buy unlock code for Imagio.

Why dont you want to call verizon? They are perfectly happy to unlock the sim for you as long as you dont have any problems with your account like delinquent payments. I called and had both of my phones unlocked in minutes and tested my ATT sim card, worked great on the aTT network

GSM 3G on america?

Did you see if you had E or 3G or H?
I've looked at the specs but haven't found the GSM 3G bands that it has.
Just this:
Digital Dual (CDMA,PCS) /1X, EVDO /Rev.A <---- perfectly clear
GSM Quad Band (GSM/GPRS/EDGE) <---- perfectly clear
WCDMA / HSDPA / HSUPA <---- not clear if it has 850mhz here
I guess it doesn't have 3G in 850mhz but I still have hopes.
Regards!

I only get "E" - my SIM is 3G capable, but the corporate plan is text-only. In other words, I can't say for certain if it will get 3G speeds. HSDPA is available here in the US, so it should be possible for an Imagio to have 3G in the States.

I called yesterday, told them I would be going overseas, they gave me the unlock code. Simple as pie. I can use my neighbor's AT&T sim card without any issues minus stuff that is Verizon specific.

The SIM unlock was easy and successful. Just call Verizon at the above number and its a done deal in 30 seconds. Will try my wife's SIM in it later.....woohoo....

because i dont have vz wireless phone number, but i need to use the t-moible or at&t, i call them, but they need me vz wireless phone number... i dont have, they not unlock for me

as i was told u are able to get it unlocked verizon will do it if ur account is 3months old and in good standing... also as far as using it on gsm not sure as of yet but will say tmobile basic signal i E in an area where out of ur basic ntwork jumpin off of another tower it will put u on H or even G but there is no 3G

H is HSDPA, which is 3.5G (faster than 3G... 7.2mbps compared to 1.5 mbps or something like that)
Edge is like 0.3 mbps and GPRS like 0.1
not really sure, but you get the idea.
Here in Mexico we have HSDPA but never get above 2mbps, at nights we do peak at 3mbps but avarage is still at much 2mbps.

Did I do something wrong?
I told them I was going over seas, I gave them my sim number and they said I was all set to go over there. Does this mean my phone is unlocked, I didn't have to put in any numbers. I will hate myself if I said the wrong thing. And if I did it right then how do I switch between sim cards and cdma?

For you phone to be unlocked they would have to give you a number to enter.
To switch between sim and cdma, go to settings -> phone -> network and change it from global mode to GSM

Not true, works fine with t mobile and at&t, didn't enter any numbers did it all from their, weird, but whatever.

I think a few things from the last three posts need clarification:
1. When you call VZW Global Support, they should have given a security code to unlock the SIM. It is a string of numbers. It is not a phone number.
2. Once the SIM is unlocked, if a SIM is present in the phone, there is no guarantee that switching back from GSM/UMTS to Global will switch the phone back to CDMA. There have been times where I've done that, and the phone has stayed on AT&T (my employer uses AT&T). I think a better method is to use either CDMA or GSM/UMTS, and to avoid the Global setting completely.

On item number 1 I would agree with you ignore my experience because even my friend who unlocks all kinds of phones for metro says it is a weird case. I have never received any unlcock cod yet it says "sim security unlocked" probably will be screwed up if I ever want to flash or reset it but whatever.
On number 2 I can't agree with you because I bought an at&t go card just for sh**ts and giggles and I have no problems, infact I can switch between the two while the phone is on, done many tests. But if anyone else experiences this issue I would like to know.

I have never heard an unlock like that. But could be... like an 'on air update'... Most times is a code or the frown upon methods (connect it to a PC or a box).
If any one wants to know, no it does not have GSM 3G for 850mhz band, not 3G with ATT and others in the world that uses that band. Tested it myself.

Even if you run at&t 3g it is much slower than verizon's. Either that or safari renders slower than s**t on brother's Icrap 3g. T mobile's is faster if you can find their 3g coverage, good luck.
PS I am still looking for internet connection settings for tmobile as I sold an unlocked imagio to my buddy and he can't get the data connection working.

does anyone ever solve de 3G problem with the 850 MHZ band... I live in Venezuela use movistar i ve the imagio sim unlocked can´t get 3G due to band restriction

Why im Roaming with AT&T phone + BELL / TELUS SIM

Hi,
I would like to be able to modify my AT&T radio and change the default Mobile Network Code for my carier, is there any software to make easy to modify the ROM file ?
Thank

I'm not quite sure I understand what you're asking, but a radio will work on various different networks, depending on which SIM card you have in the phone. So I'm not sure that it's in the radio that you need to look.
What is it that you're trying to achive exactly, why do you want to change this code ?

Well, here is my problem;
I bought a Tilt 2 on ebay, and I also get an Unlock code for it. I have inserted my Bell SIM and the phone work correctly. I have configured the APN setting correctly and now I have internet without any problem.
The only bad thing is that the phone always think i'm in roaming, but that's not true. I have to deactivate all setting about roaming check, it's not a big thing but If I got to USA I will be charged for real roaming. and another downside is that many application pup info about roaming and data charge.
I'm searching since couple days to found a solution, and I'm pretty there is one but I have not enough knowledge on programming stuff. I've look all every registry in my phone and no one can't correct this ''roaming'' situation.
That's why im turning to Radio, since this phone is an AT&T, it's propbably seaching to compare SIM network provided and ROM network. I've found an interesting site about MMC/MNC http://en.wikipedia.org/wiki/Mobile_Network_Code
and found that the default network for AT&T is 310-410. Here in Canada We have bell and telus that use same technology then AT&T (UMTS 850 / UMTS 1900).
I would like to change the default ''home'' network code to 302-880. because my Sim Provided IMSI is 302-610 (Bell).
So to make it short. I want to change the default ''HOME'' network 310-410 to 302-880 so the phone will not be in a roaming profile.
Hope that someone can help me, and I'm pretty sure many people will appreciate this fix.
Thank You.

I don't know much about this, but surely it's your SIM card that is providing this code ? Since I could buy an unlocked Tilt 2 and put my own SIM card in it, and use it fine here in the UK on a UK network.
I can't believe that your phone thinks it's roaming just because it's a Tilt 2.

Yes, I found in my registry ProvidedIMSI="302610" that is the SIM registred network 302610 Bell HSPA network. So my SIM is telling the phone to use this network, but there is something in the phone that say it's roaming and not a home network. and I need to find and change this.
I'm not the only one in this situation and i would like to find a fix.

i have no knowledge about this only thing i can think of at the moment is just change the current radio version and flash a new rom. the latest version for radio is
4.49.25.95
and is found here ------> http://forum.xda-developers.com/showthread.php?t=549939
follow the right steps. [:d]
best of luck

Yes, I've updated the Radio to the latest version and still have the problem of ROAMING. i've try 2 old radio and always got the roaming icon.
Any other input will be accepted!!
Thanks

I read somewhere that roaming starts when you are out of your area code range.
But you can try this too
go to ------> setting ---> personal ------> phone -------> Network (in the bottom tabs)
In the network tab click Find Network and make sure it is the same network you are using.
Network selection should be "Automatic".
Now in next tab BAND
select network type to "GSM" and GSM/UMTS band to "Auto".
Try this and let me know if this work else i will ask somebody knowledgeable like Sir Phunkee

I've just test the phone with a ROGERS SIM card and I get 3G signal and i'm NOT in roaming mode..
Now, What that mean ? Rogers 3G is UMTS/HSPA 850/1900MHz same as BELL.
Why it say Roaming when phone is connected to BELL with BELL Sim and not on ROGERS SIM??
Could someone help me with that ? fix, cab, anything ?
Thanks

Hi
I do not know think you want to do with your tilt 2
Why you don't do a hard SPL and install a cocked rom !! as energy
I am using a tilt purchased from AT&T without contract
I get a unlock cod from the internet then I do a hard SPL it and install the energy rom in, is work like a charm with Rogers, without any problem( only the gps wish I never try
Perhaps this is can resolve your problem you should try
thanks

Already done Cjoco My Tilt 2 is Unlocked and Hard-SPL with latest EnergyROM.
Like I said before, SIM ROGERS work like a charm in my phone, No roaming warning. but with BELL and TELUS SIM I get the Roaming notif but it's not true, Im connected to BELL and VOICE,DATA,etc. work #1.
People say that it work with ROGERS because this carrier have a fallback signal if 3G is not available, with BELL if I lose 3G signal my phone doesn't work.

then i think problem is with your sim card not with your phone. Just get your sim card replaced and i am sure the problem would be resolved.

the problem may be with his sim card, but im not sure replacing it will fix anythibng. im also with bell and have the same problem on my fuze.
bios2k, how old is your sim card?

bobzero My SIM card is 2 Week Old. so, i'm not sure it because my SIM is old.
I'll give a call at tech support @ BELL to see if they know why it doing this. I'm not sure if they will be enough good to explain this situation.
I've read last night on many forums the RILPHONE.DLL could be a possible cause of our problem.
In my config I can select GSM(850,1700) + UMTS(850,1700) but there is no option to select UMTS only. so maybe the phone is searching for GSM first (rogers) that's why when I insert a ROGERS SIM my phone is not roaming.
Is there a way I can extract RILPHONE.DLL for our EnergyROM or Stock Tilt 2 rom. Maybe I can ask a Programmer to take a look at this DLL to see the code.
I'll let you know.

I've just talk with BELL technical support and they have no idea why I'm the phone say it's in ROAMING. I've talk to the billing department and they say I don't have any ROAMING fees, so nothing to worry about..
Now, I'm still at the same state = no solution

Same here.
I was checking around and found many got this problem, including BBs. Now, some claimed that after upgrading the O/S for his BB, it went away. Another person with different device upgraded his O/S and started having that problem, and it wasn't there with stock ROM.
Make me think it has to do with the software side of thing and nothing to do with SIM or radios. To pinpoint what is causing it, can be a tough task though.

scooper True, Hard task for people that don't know much about programming ROM and files, but maybe we can have help from other that wanna look at our problem.
I'm available to test if someone want to Help us .

You should try to change the radio and rom of your phone. Make sure to Task 29 b4 flashing. Another thing to make sure is you use the right radio, i mean the specific radio for telus, t-mobile or att.....
Wrong radio can also cause such problems.

I have the same issue with my Unlocked Tilt2 on Telus. I found a lot of people with unlocked winmo devices on bell/telus complaining of this problem and never have seen a solution. People say that a Fido sim will do the same thing. Only Rogers sims seem to not show roaming. PLEASE post if you find the solution or even cause of this.

I just did task29 and reflash ROM. I soon as I have the main menu Roaming Icon appear on top just beside or 3G.
Damn!! still stock with this roaming issue
anyone have Q's ?

In need of instruction...

To give a back story on what I'm trying to accomplish, I'll explain my situation.
I work for Bell, in a retail store, the main reason I came to these forums was to find a way to re-flash phones in store to avoid having to doa what little stock we have of the phones. One of my colleagues from another location told me about the new update from Kies locking phones up at a ridiculous rate of 25%, so I'm trying to be pro-active about it.
Once I got in, I got a bit carried away with 2.2 software and what not. Now, i'm no expert, but I'm computer literate and made sense of most of the process, some extra guidance would be nice though.
Playing with the phones we have in store, I was able to flash every available software I could find on said phones, however a constant issue is found. I can not get a solid data connection. If I disable data, everything works fine, soon as I turn it back on, nothing happens.
Furthermore, I followed a thread regarding re-flashing everything back to Bell's stock settings and it didn't help me along at all.
I have done some searches, but i'm coming up dry. I know you've probably heard this hundreds of times and I'm sorry for being new to the process, some guidance towards this all would be great.

Can you elaborate more on this?
what do you mean by unable to get a solid data connection?
what kind of data connection are you referring to?
USB cable between phone to PC?
or Wifi data
or APN (3G) data?

not sure where you got that number from, but it's not that accurate
the reason for the ridiculous high amount of returned phones is due the Internal SD card problem that was found.
even under normal conditions if it gets formatted a lot or used a lot it seems to die faster than its Europe counterpart.
apparently on the Canadian version of the I9000 they use a bad batch of Flash Disk for the storage memory
there is a sticky Topic Poll about it.
it is NOT the ROM flash from Kies that are killing the units, just anything software that constantly access the internal SD can produce the same effect.
http://forum.xda-developers.com/showthread.php?t=793404
the rest of the returns you guys at Bell are seeing are due this other problem discussed here http://forum.xda-developers.com/showthread.php?t=775017
it can be reproduced, but you need the ideal conditions to do it.
it has to do with signal quality and tower availability

I'm referring to 3G connection. I have set up the APN, even tried different settings, all producing the same results.
In regards to your second reply, the phones I've seen at this location for DOA's have mostly because of a failure to fully turn on, the display won't show. I've experienced similar issues when a flash doesn't work properly, a re-flash fixes it. We started seeing this issue after samsung released the update. However, I'm not going to flash a customers phone to have them lose 3G connectivity, or open up other issues.
Basically, I'm looking for two things. Primarily a way to re-flash everything to work as if it were out of box, with the latest software update. Secondly, to be able to get a stable 3G connection on 2.2, everything else seems to work fine at this point.

i'm not even going to touch the 2.2 topic as it's not even released officially.
the current stable official flash is JH2, on JH2 3G should work properly (stable), another thing you can do is to go into the service menu using the secret codes (wiki) and make sure the proper 3G bands are selected for WCDMA
1900 and 850 should both have a start next to it
next check is the *#0011* to see if the towers keeps constantly changing
that's another reason for unstable 3G if the phone keeps jumping towers every few seconds
this is also related to the 2nd link i mentioned about people getting Comatose Syndrome on the phones, which locks up the phone, and they have to reset the phone to get the phone to work again.

I'm running JH2 currently, I ran *#2263# 850 and 1900 are available. Also, ran *#0011# both are available, ran a test on youtube it worked for 5 minutes.
Any ideas?
**Edit**
I lied, on the *#0011# it only shows 1900.

Get something straight
the update samsung released was JH2, and it is not causing the problems you've seen.
the problems with the symptoms described are after they were flashed by the Alpha & Beta versions of Froyos 2.2, which many of them do end up losing the 850 band, the band issue can be fixed with much work.
there have been at least 4 different leaks of froyo, each one bringing its own volume of chaos and bugs, the most dangerous 2 are JPH and JPK, one loses the IMEI / ESN number ID, the other one kills the internal SD

Since the I9000M and I9000 are hardware based bands, you should always have the 850 and 1900 bands for 3G
Many who have tried Froyo and back had come across the problem of losing the 850 band, mainly because the Froyo leaks were intended for the Korea test team running international I9000 devices
some times just by flashing the Firmware back to stock or Froyo betas doesn't actually activates the 850 band, even though it shows as selected in the Service Menue
if you go back to the Band Selection screen of the Service Menue, you should choose bands that are knowingly not available in canada, like say band 900 for example, and then go back again to the service menu, and band selection to only choose 850
once you can confirm 850 works, then you can select 1900 as well, and now both of the bands should be active permanently until some body else screws it up again.
using *#0011# and trying to call the voice mail are the fastest way to verify for line and for 3G on 850
you can also try the app speedtest from speedtest.net

[Q] Please help me, no 3g, then no data at all

I bought nexus one from my friend.
I am currently using HD2 with 3g data.
When I plugged in my sim card to the n1, it only worked with edge.
So, I seared internet for some information and I found out something about "*#*#6436#*#*" and change the setting to WCDMA only. Then the phone got no signal at all, so I changed back to WCDMA preferred. Then I did ping test but it did not seem to work very well.
Then I played with some APN setting and I realized that I lost data connection completely (phone still working)
I have tried to reset the phone but no luck.
Can anyone please help me with the problem? I am using T-mobile.
Thank you.

Pull your battery, and look at the back of your phone. At the top of the dark area there are numbers, look at the PB or FCC ID numbers. If they end in 9110 then you have an AT&T version of the phone, and the hardware will not work with T-Mobile's 3G service...

are you in the USA? you need to list your location. it is likely that you purchased the wrong version of the nexus one. there is an ATT version and a tmobile version. each only works with the proper 3G. so an ATT n1 on tmobile only gets edge, and vice versa. check which version you own.

GSM on the Sprint HTC One M7

Alright, this is my first post to my recollection, so Im hoping this gets some great responses.
I own a network unlocked HTC M7, coming from Sprint. The thing is, Im in Jamaica, and im using a local service provider called Digicel. They do have 4G services, but regardless of the band I select I only get GSM. Thats the best it gets to be honest. On WiFi, Im all fine, but once it hits mobile data, I automatically get back to the days of our fore fathers.
I have done some research on my own and found that Sprint apparently provides 4G on their CDMA network. I am not very sure if this phone may have 3 radios as a result, and thats what causes this, but I needed some help. I literally just phoned support (Digicel's), who sometimes doesnt seem to have accurate information easily accessible indicated that Digicel's 4G data is available on their 1900 band. TBH, Im not very sure they are certain, and really and truly I am not either. Can I get some help with confirming if this can be used on other carriers comfortably re the radio config?
and if so, is there anything that can be done to have this use 4G on my network? I already did the *#*#4636 thing and ran through all possible network types. Still having the issue. Running lolli 5.0.1.
*Update
After having done some more research, I have found that the local service provider uses the 850 band for their 4G mobile data.
