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

Samsung Galaxy S i9000 on Telus 4G LTE SIM?

I picked up a used Samsung Galaxy S i9000 that was on Virgin (CDMA?). I rooted it, and put JB on it. From another device, I have a Telus data plan that is on 4G. Looking at the i9000 specs, it says it supports GSM and 3G. This where I get confused. The Telus plan I am on is 4G LTE (data). Does this mean that this Sim could fall back to 3G if I use it in my Samsung? I have ran a number of unlock tools (including the Samsung Galaxy S Unlocker) and think that my phone is unlocked, but the radio shows that there is no connection. When I ran the unlocker, it completes but does not say "its done". I can see that I now have the correct APN setting for Telus. The phone sees my SIM and my phone #. And I have the nv_data.bin file ( was not there before running the unlocker). When I look at the phone details, it sees my SIM, knows my phone number etc. It just won't connect. It also has the correct APN settings. If I try to dial a number or use the data, it does not work. Wondering if there are other settings I am missing?
I think the issue is that the sim only runs on Telus 4G and does not fall back to 3G (what the phone is capable of), but again, this is where I am green. I don't know how this works. Does the phone 'ask' the Sim to fall back, or does the network and Sim dictate to the phone what network it will use?
Area of coverage: Burlington Ontario (GTA). Sorry if this has been discussed, but my search terms did not find anything.

4G LTE not active

I have an unlocked Galaxy S4 active i9295 and I cannot get the 4G or the LTE working since I do not have even the option I only have WCDMA/GSM I travel around the world with this phone and now I am in Ireland on 3 and still I am getting H+ showing and not LTE or 4G. Is there a way to activate 4G or is there any special 4G sims ?

I would check your APN settings, seeing how you are unlocked, the proper APN may not be installed to match your Sim, check with your carrier, to make sure they are 4G and LTE capable and get their settings.

Try ShowServiceMode. It should help to unlock LTE band. It worked for me here in Poland, because local career's LTE was locked by my Russian firmware. But using this program I can only switch between phone calls (GSM/3G) and LTE, they cannot work simultaneously.

Thank you guys. One major thing is that why I can even see the option in the settings? If anyone else has some information please help out.
Thanks

Is it cdma or gsm?

I tried searching it, but I kept finding it for other phones and then answers that did not fit what I have. The most common answer is, if it has a sim card, it is GSM. Sprint is CDMA though, so is it CDMA and GSM? When I took the SIM card out, it said that I would not be able to use 4G LTE without the SIM, but I still had full bars, so does it use GSM for 4G, but CDMA for 2G (calls and sms). I was told that the Google PE RUU did not work on my phone because it only works on GSM, but then when I ran MSL finder, it told me it had no MSL (ie not a CDMA phone) and I have en IMEI, not an ESN.

This should be in q&a

If you're on Sprint or Verizon, you're using a CDMA carrier. Since CDMA is too old to support LTE, they used the SIM card to access access GSM technology (LTE) To keep up to date with the new carriers that are running insane download/uploading speeds using LTE.

Got it...I was looking at the some hidden menus and I found the section to choose GSM/WCDMA.CDMA/LTE and some other few options. Thanks for the clarification.

Yup, if you choose GSM/UMTS, you won't be able to receive data at all since Sprint isn't a GSM carrier.

On that note, it has several options, including CDMA only, GSM only, and then gsm/cdma/wcdma/lte (ie all of them). Is it prudent to just leave it on all, or since I am going to use it on Verizon and/or sprint/ting, just leave it cdma/wcdma/lte? If I choose the catch all one that includes gsm, will it affect the phone negatively, as in extra battery usage, overheating, no signal, etc?

If you switch to CDMA Only, you're gonna get a much longer battery life than if you were using CDMA/LTE since your LTE service will be disabled. This means that you will only get 3G but your battery life will last longer since LTE requires more power than 3G

Verizon SIM on band 2 & 4 in T-Mobile H811

Now that Verizon is rolling out band 2 and 4 LTE, I thought I'd try an experiment. Some background: I have a Nexus 7 LTE (2013) with Verizon data-only SIM, and an LG G4 H811 on T-Mobile. The H811 is SIM/network unlocked. I attempted putting the Verizon SIM in the T-Mobile phone. Full signal with Verizon SIM, but no "4G LTE" indicator. Attempted entering Verizon APN settings, but they would not save. (Is this device specific, or is the SIM card rejecting the APN settings?) Tried simply entering Name "Verizon" and APN "vzwinternet" but omitted MNC and MCC settings, and now "4G LTE" indicator DOES show, but no internet connection. Under About Phone/Network I am connected to Verizon on my H811 and Mobile network type is "LTE" but still not actually connected. Any suggestions for entering the Verizon APN info on a T-Mobile device and making it stick? I'm a paying customer on both networks, so please no indignant comments about "why don't you just ditch T-Mobile and/or Verizon?" This is just to satisfy my curiosity.
FYI, the Nexus 7 LTE (2013) does not have CDMA radios, so I don't care that the H811 also does not. Shouldn't the SIM work for the LTE bands that the H811 does have? Doesn't Verizon have some deal-with-the-devil arrangement with the FCC regarding their LTE that they have to allow any device on their network?

Is your H811 rooted? if so you may want to try injecting the APN into the apns-config.xml file located system/etc

Not rooted. Just found out how easy it is with unlocked bootloader. This might my next weekend project. Might also try unlocking band 13. I don't suppose anybody's tried that with the H811 yet?

You could open dialer. Type 277634#*# then touch unlock apn. Then you can get the g4 an changes stick

Small issues for you:
1 - You might have data on 2 & 4 (eventually), but you won't have CDMA connectivity and you won't have VoLTE, so you'll never be able to actually make calls.
2 - Verizon has a device whitelist (and blacklist) in place, so they actually need to ALLOW your device on the network, vs. a traditional GSM based telecom who simply implements a blacklist. The reason you aren't able to connect to anything even though it shows as connected, is because they haven't allowed you on their network. Here's the ****ty (****tier) part: Unless you have a Nexus 6, iPhone or a verizon BRANDED phone, you won't be allowed on. They've been very clear about this for about a decade now, and they're not changing anytime soon.
Small edit: The APNs allow you to connect to the network in the first place, so the APN isn't the issue here. The whitelist is.
