I unlocked my MyTouch 4g (Glacier) and I want to use my Verizon sim card in it but it does not detect Verizon in the network operators. How do I get verizon on there? Is it possible? I thought unlocking it would allow me to do this.

Verizon does not use 'SIM' cards
as 'SIM' cards are used for GSM networks and Verizon is a CDMA provider

I did google this extensively. The phone that I have here is on the verizon network and has a sim card. Why would I make that up?

Verizon is a CDMA network. The SIM card is there because the phone you have also has a GSM radio for traveling overseas. However, just because it says "Verizon" on the SIM card doesn't mean your phone connects to Verizon when you roam. It's actually connecting to Vodafone when you're roaming in most countries. That's what the SIM card slot is for. Now if you unlocked that phone, you could use it on T-Mobile or AT&T if you set it to GSM Mode.
That Verizon phone will work in the US and Canada whether or not that SIM card is in there. It's impossible to get a GSM phone (your MyTouch 4G) to work on a CDMA network (Verizon).

Thank you for the real explanation and not being a jerk about it, as I did not know this.
It sucks that I cant use it but now I know.
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 just bought Verizon Samsung SCH-I705. I just wonder that can it could be unlocked to use Tmobile SIM. I know that this one has LTE SIM but just wonder?

This has been asked before and the answer is still the same
Verizon - CDMA Carrier
TMO - GSM carrier
Two different radio's. You can use an unlocked TMO tab and use it on AT&T (Another GSM carrier).. The Verizon tab shouldn't have a SIM card in it. Unless it is a World tab or LTE. In the LTE case, only the 4G is sim controlled, the 3G is controlled by the CDMA radio.
Verizon:
Frequencies and Data Type Digital: (CDMA/PCS)/1x, EVDO Rev A, LTE (Band 13 only)
Tmobile
Frequencies and Data Type GSM: 850/900/1800/1900
So your answer is no.....

I believe you answer is just partially correct. My Verizon Tab has a SIM slot. I currently own a Verizon Iphone 4S, Iphone 5 and Samsung S3. Used to own BB Tour, Storm, Bold, HTC Incredible 2, HTC rezound. After unlock, all of them (they have both CDMA and GSM) can be used with any SIM card. That why Verizon called them Global Phones. I also believe that the Samsung S3 is LTE phone with SIM card slot and I have no problem to use it with my TMO SIM card

My US Cellular S3 had a SIM card too, but USCC is a CDMA phone. The SIM card was for 4G LTE only as USCC is a CDMA carrier. Some of the BB was "World Phones" meaning that they had 2 radio's in them, 1 CDMA when you was in the USA, the other was GSM when you traveled outside the USA but could not be used inside the US unless it was (the GSM part) unlocked. I know there are some other Android "World Phones" I had the Motorola Electrify, I think it's counter part on Sprint had a different name. There was a few more on USCC that was World Phones, They had dual radio's. But the S3 and Note 2 didn't. But I would guess that it could be possible that Verizon's variation could be different. I never looked that close. But if there is a way to unlock it and use it on a GSM network, then do a search, the phone is old enough to have already been unlocked, and a search would turn it up if it was. If your search comes up negative, then you will have your answer.

Thx for your reply. My Verizon Samsung S3 was unlocked by Verizon (by agreement from verizon with FCC) as they did with Iphone 5 (can be considered as factory unlock). Both of them can be used with GSM carrier here but not the Iphone 4S (for abroad use only even it is unlocked by Verizon).
I searched and have not seen any solution for unlock the Samsung Tab I705 in US but there are unlock code for sale for I705 in Europe and in Asia. I checked the I705 specifications but only see LTE 700Mhz, Class 13 (as you stated) in your previous post. Same thing with Verizon Samsung S3 I535 but I can use S3 with TMO sim. That is the reason I want to find out anyway we can unlock I705 (Tab 2) to use with SIM card for GSM carrier. Anybody can help?
DAMN!
I was looking for the same thing!
>.>
yes it can be done
I know that the verizon galaxy tab 2 can be unlocked. A friend of mine had verizon do it by claiming they where traveling outside the country, and it works on T-Mobile just fine. because it does have both radios. PLUS i want it for the LTE anyways and it does work for the t-mobile LTE. problem for me is that i no longer have an account with verizon so they will not give me the unlock code for the tablet so i need another way to unlock it.... can i do this by rooting it and putting a customer ROM or does that no effect that portion of the tablet.

I have Samsung Tab E Verizon SM-T567V it's Global and 4G supported with a dedicated sim slot. How to sim unlock it???
I currently am using my nexus 5 (unlocked from Play Store) on sprint and I will be going out of the country for a couple weeks and want to use a local SIM card when I get there. I have a couple questions.
1) what do I need to do to switch from Sprint CDMA and LTE SIM to a foreign GSM SIM?
2) once I get back in the country what do I need to do to switch from the from the foreign GSM SIM back to my Sprint CDMA and LTE SIM
Just simply swap the sims.
That's it? No changing anything in the settings or calls to sprint? Seems too good to be true. Glad I chose a Nexus!

Hi All,
I bought a Tmobile galaxy s blaze 4g (SGH-T769) from HSN last year, it was never activated or used on tmobile. I tried to put a old at&t sim I had in it and it said sim invalid. I get the same message when I put an active Verizon sim in as well.
I used a service online for an unlock code and after following the directions it prompted for pin and it seems to be unlock after entering pin
When I insert the Verizon sim it does not display invalid but it cycles between Verizon APN and Vodaphone NL .
When I try to make a call it said not registered on network
When I put the at&t sim back into the phone, I get the not registered network but am thinking because its an old inactive sim or not?
My issue is I want to use this phone in Brazil this summer so I need it unlocked and right now I am not sure if it really is unlocked?
any ideas?

Just so I get this correctly, Verizon, even though it has a sim, is CDMA network Only. So my my only option to test is a vlid AT&T sim?
Thanks for responding
update
I used a friends at&t working sim and it worked great so the phone is unlocked. I guess the Verizon 4g lte is different frequency anyway plus for some reason I thought it was some form of GSM. lol
ALL good to go here..
