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
Just got my Droid 3 yesterday, and I activated it on my account. Do I need to do anything special to enable International Roaming?
All I did so far was register the device MEID to my Verizon Wireless account (I was previously using a phone that did not have global roaming). And the Droid 3 connects just fine here in the US on CDMA bands. Do I need to do anything to "register" the SIM card that came with the phone?
Thanks.
Sent from my DROID3 using XDA App
As I know you need to call VZW and activate your SIM card.
You only need to register the sim card if you plan to travel outside USA. It doesn't hurt to have SIM activated just in case. To do it, you need to call Verizon Global Support.
BTW - while in US, I strongly recommend you to switch phone to CDMA mode instead of Global as this will save you quite some battery especially if your CDMA coverage is not perfect all the time. Switch to Global only if you leave US travelling to country like Canada (where there is compatible CDMA network you can roam on). All other countries, switch to GSM/UMTS only for best battery life.
Hi,
I am a newbie here, so bear with me
After much research and trying to understand what each model was, i bought a moto x (1st gen) developpper edition unlocked.
It is supposed to be new. has the white back and the black front.
I am using it with ultra mobile. Got the sim cut to nano size with a punchout tool.
Thing is the sim goes undetected.. the phone does not get a signal (although I think it can detect networks). but shows the sim undetected icon in the top.
The sim has been checked and works perfectly fine in several different devices.
What am i missing here?
While I did not realize the seller listing did not list GSM as a feature, it does list the following:
3G UMTS bands: 850/900/ AWS/1900/2100 MHz with HSPA+ up to 42 Mbps (B5/B8/B4/B2/B1)
4G LTE bands:700/AWS/1900MHz (B17/B4/B2), Wi-Fi: 802.11a/g/b/n/ac (dual band capable), mobile hotspot
From what you mentioned you definitely have the GSM version. No worries there. The developer version, besides being half Oreo, will also say Developer Edition on the back.
Not that any of that matters for your problem. A sim undetected issue is between sim and phone, the network is not involved yet.

Did you check the sim after you cut it to nano or before? Make sure it works in another phone in it's nano form (no putting it back in the cutout). You'll need another phone that uses nano sim.
An improperly cut sim will have issues. If sim is the problem easy fix just replace it.
If sim checks out then check your phone with another nano sim to make sure it's not just that one sim it doesn't like. if it's the same result then you might have a hardware issue.
Yes, thanks I checked the sim in other devices, it worked totally fine.
Thanks so much for your reply..So i received the cutter i had ordered and we did a last ditch effort, using it to make sure the sim got cut properly.. Surprise it worked! Phone is good to go and completely working.
This was simply an issue of the sim not being cut properly
I got a Razr I XT890 running retail 4.1.2 en.EU rom and despite bootloader unlocking (out of warranty now and rooting neither of two sim cards for Union Wireless (Wyoming, U.S.A.) nor one for Verizon show as recognized: a sim icon as well as the signal bars both have red, crossed circles over them and "Emergency Calls" displays on the bottom of the lock and home screens.
I took it to my carrier and they suggested that perhaps the sim card reader was damaged but I absolutely love this phone; has anybody had or overcome a similar problem?
Dunno if this is true, but is the razr i not a gsm phone and u need a cdma phone to get it to work in the usa? So only the razr m works there?

Verizon is definetely a CDMA carrier, meaning you absolutely need a CDMA phone that is from Verizon directly, same with Sprint in the U.S.
You can either use AT&T or T-Mobile or H2O in the U.S. with your Razr I, before you buy anything, double check on which frequencies those networks operate (cause its different) and then check which one of those are covered by the Razr I.
The Verizon sim card doesn't really do anything, they provide it for their customers who go global, for domestic service all information gets programmed directly into the phone by Verizon when you register a phone with them. Most Verizon phones don't even habe sim card slots, cause they want you to stick with their carrier til the end of time, some phones do, they call it "global ready" then.
So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.
I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.
I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.
Just for perspective, I got a EU version of the Mi 9. Popped in a T-Mobile sim and it worked out of the box. Try the other sim slot. Could be your sim card if not.
Try these codes in Dialer. See if that helps anything.
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
I was just making an ATT account so no previous activations or sims. So that could be the issue. I will try activating a sim with an old phone and then move the sim over. Or since it is the same hardware as a Galaxy S10, ill see if I can find a store that will activate a sim with a floor model S10 and then let me swap the sim into my Mi 9
Straight talk (ATT sim) lte without issue. no programming necessary , I have the global model though

Where did you guys buy the China version from?
US mobile white SIM from starter kit (T-Mobile) works well with LTE on Chinese model of Mi 9. Black one (Verizon) technically works, registers in the network and enables data, but Verizon refuses the IMEI as non-certified brand of the phone. Trick with activation on the iphone first and switching to xiaomi did not work, service gets cut off, when trying to make a call, it keeps dropping. AT&T based: Cricket and Straight Talk work just fine too.

Thanks for the info.
I was wondering about Verizon, since it support some CDMA bands and support 2 out of 3 of the LTE bands they use (doesnt support B13). Unfortunately I never tried it myself since half the coverage near me uses the band this phone doesnt support on Verizon.
I went and got my ATT account updated to an old Nexus 6 IMEI number and it got LTE on the N6. I then took the sim and put it in my Mi 9 and now the Mi 9 has LTE. So for anyone just getting this phone, you must have an IMEI on your account that is recognized as an LTE phone. If you try to add the IMEI of the Mi9 it is not recognized by ATT and wont provision LTE.
IMEI spoofing does not work with Verizon, as they simply ban the device. They call it “non certified”. Bands are seem ok.

I been purchasing from liaow. Never ran across a issue with them
I've been having the same issue, with a recently-bought (last week arrived) Mi 9 Global on AT&T postpaid. LTE showed up and worked fine day one, now network speeds are dropped down to 3.5G speeds. Anyone else have success with getting LTE on a fresh SIM?

I got the Chinese version and I'm in the US. And I I have the straight talk T-Mobile sim and everything works like it is suppose to expect my internet. It says its 4g but it is very very slow. Any ideas?
